DMDM Hydantoin: What’s In Your Shampoo?

Most of the cheap drug store shampoos like Suave, Got2B, v05, Finesse, Dove, TRESemme, etc. usually contain an ingredient called “DMDM Hydantoin.” Actually, most professional-grade hair products use it too. So, what is this mystery chemical, you asNMGC 3EVC 1GNS 994Fk?

You will find DMDM Hydantoinin many hair and beauty products but do you have any idea what it is? The answer will shock you...

What is DMDM Hydantoin?

Wikipedia says that “DMDM Hydantoin is an antimicrobial formaldehyde releaser preservative with the trade name Glydant. DMDM hydantoin is an organic compound belonging to a class of compounds known as hydantoins. You will find this chemical in the cosmetics industry, in products like shampoos, hair conditioners, hair gels and skin care products.

How does it work?

This nasty chemical works as a preservative. The formaldehyde it releases makes the environment less favorable to the microorganisms. I wonder how our scalp and hair like that…

Scientists are concerned that since this preservative releases formaldehyde into the beauty product, it may cause consumer exposure to a well-recognized carcinogen. In case you don’t know, a carcinogen is a cancer-causing substance, like Formaldehyde. They use this ingredient in shampoo because it kills other fungus and bacteria. Ewww.

When you read the back of the shampoo bottle, you will most likely see "DMDM Hydantoin" listed, but what is it? The answer will shock..

Your Turn: Have you had any horrible experiences with ingredients found in beauty products? I’d love to read your feedback in the comments section below…

Not all OTC shampoos are using it. I checked all of my hubs suave that he loves, and none of it has this. Neither did my BIOLAge or redken. However, I do use SuAVE to clean my bathtub, not my pro products 😁

My reactions were itchy head;when combing out a batch of hair would come out; quit combing and used my fingers to detangle, no better. My hair would just come out on my hands, I would have to lift it off my fingers the first couple of times then it would slow down to only a few strands. I noticed it was more at the top of my head where I would scrub off oil around my face/hair.

So what are you using now? I have this issue too! I've been taking collagen to help but I'm not seeing a difference. This may be why
