Blondes seriously have more fun… or at least that’s what I usually tell everybody.  I’m 26 and started bleaching my hair when I was 12.  Even though I always go back to the dark side every once in a while, I always end up with platinum blonde hair.  I’m just happier with blonde hair.  I feel like it brightens up my face.  Since most people are in the same boat, let’s talk about how to keep bleached hair healthy.

Do you want to know how to keep bleached hair healthy? Learn a few tips on how to keep your bleached hair in tip-top shape...

How Hair Lightener Works:

If you really want to learn how to keep bleached hair healthy, you should first learn how lightener works.

Bleach can take its toll on your hair very quickly.   It basically works by penetrating the hair cortex and removing all color pigment.

  • The first component of hair lightener is an alkaline, which lifts up the “scales” of the hair cuticle to allow the next step to happen.
  • The alkaline is mixed with an oxidizing agent, which allows it to penetrate deep in the hair shaft to the area where color molecules hang out.
  • Once it’s in there, the bleach starts to lighten the pigment molecules by releasing oxygen molecules during the oxidation process.  These oxygen molecules break up the chemical bonds of chromophores, the parts of molecules responsible for color. “The changed chromophore molecules either reflect no color or a color outside the visible spectrum. This absence of color is seen by our eyes as white.” (Wonderopolis)

Hair lightening goes through a series of phases.  Remember the three primary colors that make every other color are blue, red and yellow.  Bleach first removes the blue molecules, which leaves the hair red.  This process is very quick, so if you blink, you’ll miss it.  Next, the red molecules start to come out.  This process takes a long time, and if you stop in the middle, you may end up with orange hair.  The last part of the process removes some of the yellow pigments, which results in a pale yellow.  The natural color of keratin, which is the protein that hair is composed of, is yellow, so your hair will never not be some form of yellow.  If you want a more defined shade of blonde, you will have to use a toner, but that is a whole other article in itself.

Did you love all that science talk?  If so, you should check out this super cool article about how hair color works.

Bleach Damage:

The next thing you need to know about how to keep bleached hair healthy is to learn how it damages your hair.

Bleach doesn’t just strip the color molecules in your hair… it also strips the protein, vitamins, and moisture.  It changes the structure and texture of your hair.  Remember how I said that it uses an alkaline solution to raise the cuticle?  Well if you over-process your hair, the cuticle won’t lay back down, which leaves the hair dull and susceptible to more damage.  Remember that the cuticle’s purpose is to act as a barrier and protect what’s on the inside of the hair.  If it becomes damaged, the inside will get damaged too.

  3. Hi there, I wonder if u can help me….

    2 months ago, i got my hairdresser to bleach my dark brown hair from my eyes to the tips of my hair to create an ombre look…

    After a week of brassy bleached hair from my eyes down, i then home-box-dyed my hair a very light ash blonde all over, including my dark brown tops of my hair…

    I was really pleased with the result after using Pro Voke: Touch of Silver twice a week lightening shampoo and conditioner (purple shampoo). My bleached parts of my hair turned a dark blonde with light ash highlights, and my dark brown parts turned a medium brown…

    I now really wanna change all my hair colour to light ash brown, I know it might be difficult coz i have 2 different colours in my hair!

    Would you be able to give me some advice on how to achieve this? xx <3

    Love Alex 😀

  4. Hi. Great information on your site! Wanted to ask a quick question about toner. I have reddish brown hair with grey (naturally frizzy and curly) I like my hair blonde (a level 9N I think), so my stylist gets my roots lightened and colour deposits at the same time. once in a while they throw a toner on for toning down brassiness. My question is: is toner healthy for your hair? I was told a clear toner always good to throw on after my hair service. Reason I ask is because last few times I had the formaldehyde-free keratin smoothers done, they seemed to not work very well at all and my hair now is fragile and looks like doll hair. Will toner help? I have used everybkind of sulfate cree shampoo/conditioners too….

    • Toners are basically just color… they work by depositing pigments to cancel out unwanted tones… they shouldn’t damage your hair too much… it’s probably being damaged from the lightener. Clear toner doesn’t really make too much sense, but some color lines have a clear shine you can do after a color service and most of them actually protein treat the hair and should do minimal damage. Hope it helps 🙂

  5. Great article. Have you ever noticed that your bleached hair is slower to dry? I just bleached my hair recently and it takes FOREVER to dry, even with a blow dryer. It doesn’t really seem like it’s in bad condition or anything but I’m kind of concerned. What do you think?

    • Bleached hair becomes more porous… think of it like a sponge. It is going to hold more water molecules… good observation! 🙂

    • Steph Taillefer Reply

      Really? My bleached streaks dry the fastest cuz its there so over processed.. my natural brown (underneath and inbetween the streaks) take forever! So funny we hve the opposite !

  6. Do you have any suggestions for how to best deal with hair that is very blonde? I’m naturally dark blonde/light brown, but have been a bleach and tone for about 4 years. I moved to a new city a year ago and went to a colorist who was listed in Allure magazine as being the best – she overlapped and over processed my hair. A TON of it fell out in the salon and 8 months later it’s started to break off. My new colorist (who costs a fortune) seems better, but my hair still looks so thin and damaged. I want blonde hair still but don’t know if I should give up the bleach/tone? Is it possible to switch to highlights after all the bleach? I really want to grow my hair long, but after all the trauma it’s been through, don’t know if that’s possible.

    • I was just reading this for product ideas and noticed your comment. I’ve had white blonde hair on and off for the past 4 years and you would never realise from its condition how often I bleach it (which is a lot). Personally I bleach my hair at home using freeze bleach which has a silver toning agent built in to prevent your hair ending up yellow and since I started using that I dont even need to tone it afterwards, I use 30vol (I have dark brown hair naturally) and leave it on for approx 45 mins but if your hair is naturally lighter I would recommend sticking with 20vol as it causes less damage and should only take around 30 mins. The best aftercare products I have found so far are a decent purple shampoo (I would recommend schwarzkopf bonacure or fudge as they work best at maintaining your tone) which you can use daily as normal or if you feel like an extra boost leave it on for a few minutes (helpful if you are beginning to notice a yellow tinge). For conditioner look for a moisturising conditioner with keratin (personally I use l’oreal elvive full restore 5 repairing conditioner) and leave on for around 2 minutes after shampooing as this will help replenish and lost moisture and close the hair cuticle. Another good conditioner for bleached hair if you’re willing to spend a bit more is TIGI Bed Head Dumb Blonde which is specifically designed to provide deep moisture and repair on bleached hair. A good heat protection is always good especially when paired with a decent hair oil which will coat each strand providing further protection. The best oil I’ve found so far is morrocan oil (their shampoo and conditioner is also amazing for over processed hair… but its expensive) which is generally around £30 for 100ml, if this is too much for your budget there are cheaper versions available which will do the job however they often take longer for you to notice a difference. I would reccomend wella professional reflections oil as your best alternative, its available at salon services for around £16 for 100ml or a decent argan oil (beware there are many copies on the market which are watered down with other oils so don’t risk anything under £10) . There are much cheaper versions available from any drug store but they are generally weaker so only use these if your desperate! Oil should be applied under heat protection before blow drying and I would let it sit for a few minutes to allow your hair to absorb the moisture. I find using these leaves my hair super soft and managable. You can also add a small amount of the oil to your bleach mixture before applying as well as smoothing some over dry hair as this prevents your hair being overly dried out during the bleaching process. Only straighten your hair if you need to and allow to air dry if your not leaving the house. When straightening do so in layers as this will stop you repeatedly going over the same bit too many times. If you feel your hair needs a good boost you can make your own hair mask by mixing your conditioner with a small amount of oil, apply to towel dry hair and leave it on for as long as you can stand before rinsing thoroughly! I hope this helps because its certainly been an absoloute lifesaver for me… before this my hair wouldnt grow and I had to cut it really short multiple times and now its at my collarbone and growing steadily. I could never get rid of my blonde now and im just glad I found a way to keep it super healthy! If you have any questions feel free to send me a message on facebook as I am constantly trying and reviewing new products and I have a lot of experience with the many fun aspects of blonde hair!

      COco, One time, many years ago, I had a perm on very heavily bleached hair. From about 24 inches, I was able to salvage a this 5 inches but a beauty school instructor, He used Aphogee Treatment for Damaged Hair. Wash the hair. Towel dry. Add the chemical liberally and work through with fingers. THen, pile the hair LOOSLEY. I put a big plastic claw or two and try to get air flow underneath the pile. NO cap. Under the dryer until it is dry.l It will be hard as plexiglass. DO NOT DO NOT DO NOT touch it at all. If you do, it will break like cheap glass at this stage. Get under the shower and wet it down., letting the movement of the water remove the excess material. Once that is gone, moisturize with companion products, esp with Keratin. What this does is deposit a polymer of some sort into the shaft and cuticle and close it up for a smooth hair shaft. I have been bleaching my hair myself since 1954, including prebleaching and foiling with 4 different colors (my really beautiful hair time). Various toners, Super blue lighteners etc. Now, I am 74 and have to deposit onto grey…but, that is another issue. Grey hair is more delicate. I have had 3 episodes with perms that destroyed my hair, 2 at salons and 1 at home. Aphogee always saved my hair. I swear by the products since 1966.

    • Hi! I have been platinum since 2009 and I have been through the wringer as far as damage goes.I FINALLY got the nerve to start doing my own roots and toning my hair to save all that money and my hair is healthier than before. One MAJOR thing that has helped my hair to get strength and length is ROUX Porosity Control Shampoo and Conditioner. When we are blonde( like the article states) our hair becomes more open, and POROUS so this porosity shampoo really boosted my hair volume and helped to close up the hair strands. I have to use the porosity products especially in the summer months because high humidity really opens up my hair and it starts to get fragile and break. This has literally SAVED my hair. I went from above the shoulder length hair to a year later it is below y shoulders just slightly. Another pair of products that have helped the strength is ROUX Repairing shampoo and conditioner. This stuff is cheap( at about 8.00 a bottle where I live) and it works better than any other salon brand I ave tried.Give it a shot for a few months and you will see a difference.

  7. i bleached my hair and it turned light pink. what should ido

    • Try and use a toner. It should take out any pink tones in your hair 🙂

  8. I’ve been bleaching my hair since October of 2012.. I’ve bleached it times before, but I’d always switch back to brown.. However, like you, I love my hair blonde. I’m the happiest at that state. The blonder the better. I just had bleached my hair again yesterday, and it’s really dry. Lol. I seriously need to get back to deep conditioning it once or twice a week again!! Ahh. So much work to being a blonde lol.

  9. Hi I bleach my dark brown hair and the colour result is golden blonde so now I wana know can I use a light ash blonde to cool down brazzy colours in hair or can I just buy purple shampoo don’t wana damage my hair further

  10. i have resonantly bleached the crap out of my hair going from black to almost white (the ends of my hair have turned strawberry blonde). if found your article on google while i was looking for good shampoos/conditioners for my hair because it is fried and frizzy as hell!!! i really need to baby my hair for a while and was very thankfull for your blog. i have been using nexus leave in conditioner but it hasnt seemed to help all that well, iv been wanting to try the bed head dumb blonde products but its really really expensive. thanks to your article i have decided to use baking soda and water for shampoo and bed head conditioner to save some money. i also have secretly been wanting to skip out on shampoo also because it makes my hair feel like the bottom of a broom when i rise it out but i never thought about actually doing it or using an alternative.. im a clean freak so ill use the baking soda alternative but if it doesnt go as planned i do have back up shampoo. i also am thinking about buying a bed head leave in conditioner since the nexus doesnt seem to be work all that well. let me know if you have any further suggestions and thank you for your blog =) soon my hair will be thanking you too lol

  11. I go back & fourth between blonde & dark leave both for a year or 8 months then change. I’ve decided that I want blonde so I went blonde my cousin is a hair stylist so I bought the bleach she does. I died it & half went blonde half went orange so I tried dying it 2 more times & each time it goes a lil more. But this last time I was brushing threw & some was coming out!! I don’t know what to do. I need help.

  12. Hi Hollee, I am just about to bleach my hair, by myself, because it’s too expensive at the salons here. My hair is medium brown colour, shoulderblade-length. Just a few questions before I start – Should I start at the roots, or mid-length – I am 44, so have a few grey/white hairs mixed in the re-growth, (especially at my temples). Also, is it ok to comb the bleach through during the processing time? Thank you. Cheers, Sue.

  13. It’s better and easier for your hair if you don’t wait as long as possible when all over blonde. You scalp will only heat up the first 1/2 inch or so of the strand. Waitin longer can cause bands and may make you have to leave the bleach on longer.

    before and after bleaching, I use eggs and milk on my hair and cover that with coconut oil. Helps A LOT.

  16. Thank you so much for this wonderful information..It really has given me some courage..Don’t laugh now,but I was an entertainer many years ago,(abouot 50,I said don’t laugh),but as the years went buy I have remained blonde most of the time..You have aolready guessed my age no doubt..I had Chemo a year ago and lost all of my hair..when it came in , it was pretty much 80/20 white with grey..I colored my hair as I always have since the 70s and it came out a beautiuf Light Ah Blonde thanks to ION…I used a 1o vol peroxide…but in two or three weeks it has faded ato white for the most part and I thought maybe just adding a capeful of a toner 2 shades darker than it is now (maybe on the gold side and not the ash to my shampoo would work…no perioxide with it…Does that sound sane?:?People tell me I look great and hope to live to be 85 and when I do it will still be with dyed hair and makeup…Thank you for all that you and all the other beauticians do…

  17. Hi. I need help! I’m the opposite of you. I have snow white hair and I want it to be a 9N blonde. I just did a root touch-up with Age Beautiful 9N permanent dye. There is banding (1/4-1/2″) where the new growth overlapped the previously colored hair. I know, I know — I find it IMPOSSIBLE to just get the hair color on the new growth ONLY! My question is…how can I touch up the roots and not get the banding?? I love the color. I leave it on the roots for 45 mins., add a bit of water to the remaining color and then put on the rest of my hair for another 5 mins. Looks good except for the darn banding! Any suggestions?

  18. hey i bleached my hair but stupidly missed patches. i’ve gone over it with a light golden blonde dye but the patches are still noticable. will it be ok to just bleach the bits i missed?

  19. I’m a guy with fairly long hair, and I bleached & toner’d it as white as possible recently, but it seems so lifeless and frizzy. It used to always have nice natural curls, but now it’s just frizzy. I feel like I look like Doc Brown. Someone recommended a try Wen conditioner, so I bought some, but after one use I stopped because it looked like maybe it was putting yellow back into my hair (although maybe it was my imagination). The salon ladies gave me the Paul Mitchell platinum blonde products. Should I stick with those, or should I use the Wen? Am I imagining things, about it making my hair more yellow?

    • P.S. .. Don’t go by that picture in answering my question. It’s yellow in that picture because I had only bleached it at that point, I hadn’t yet used the toner. It is much more white now.

    • It is possible that the wen is making your hair more yellow. Yellow is the color of keratin, the protein your hair is made of, so maybe that is a good thing. What I would probably do is use the platinum blonde shampoo to tone it down, and maybe alternate between the two. Hope it helps 🙂

  20. I’m with Jennifer, your article is concise and so so full of great advice, one of the best I have read on bleaching! You rock! My hair’s been through 2 bleachings with 20 vol thus far and I will be taking to heart your advice, thanks Hollee! 😀

  21. Thank you for your advice. I have been bleaching my hair for 2 years now and I’ve always been concerned how much damage I’m doing. Your advice has really helped me see the difference a few additional treatments can make to keep it healthy 🙂

  22. Hi, thanks for a great article! I gradually went from black to blonde but couldn’t go all the way to platinum like I wanted because only the top half of my hair is strong enough – the lower half (my hairs last my shoulders) is damaged from dying it so often for ten years, but now the blonde dye has made it sooo stretchy and brittle I’m terrified its going to all snap off, I don’t wash it daily, I only use a wide tooth comb and I have purple toned John Freida shampoo and conditioner, what do you recommend I use to help fix the stretchy weak brittle hair?? Also I dyed it about two weeks ago, if I dyed it darker when my roots come through would that help the condition do you think? I’m scared to use blonde again! It’s taken me forever to grow my hair this long and I don’t want it chin length!!! Thanks 🙂

  23. I just wanted to thank you for all the good information you posted about bleached hair. The way you broke it down really helped me understand the process. Everything you said made so much sense. I. Will be useing your advice with confidence. Thanks again,

  24. I just bleached my hair out Saturday, They cut the top of my head down to about 2 1/2 inches because of damage, but I was able to keep the rest of my hair. however, I’m taking Prenatal Vitamins just to make it grow! I have an appointment for them to wash it Thursday and do the deep conditioning mask. Do you have any tips to make it grow fast? and i’ve been wearing a fedora hat since saturday because of the grease and mullet look haha. and how long should i wait to style it? The top 2 1/2 inches will look AMAZING if I can tease it, but i dont want to break it.

    • I’ve heard mixed things about prenatal vitamins… Some people argue that it is the hormones from pregnancy that make your hair grow.. Not the actual vitamins… I would take “hair, skin and nail” vitamins with biotin in them, that are formulated to promote hair growth. I think you should wait a little bit before styling your hair to let it get stronger. Usually hair is really brittle right after bleaching it, but it will get stronger! Invest in some good deep conditioner with keratin in it, along with gentle shampoo (sulfate-free) and good regular conditioner.. Preferably with keratin in it. When your hair starts to feel better, you can style it but try to keep it as minimal as possible. I would only use heat when you absolutely need to. I would stimulate your scalp with massaging and scientific brushing and try to cut down on anything that would cause breakage! Hope it helps! Good luck!
