How Does Hair Dye Work? The Interesting Science Behind It…

by

Long before I ever thought about doing hair, I was intrigued by the chemistry behind it.  I remember wondering to myself, “how does hair dye work?” almost every time I would get my hair done.  I mean, it made no sense to me.  You put something on your hair and it changes the color to whatever you want.  Is it magic? There has to be a reasonable explanation, right?  Well, it’s actually quite simple….

Hair Snips #28: What Causes Goose Bumps?

by

It’s common knowledge that when a human is cold, they get goose bumps (usually on their arms).  But do you know what causes goose bumps and what they are?  Let me explain…

It's common logic that you get goose bumps when you are cold or scared... but do you know what causes goose bumps? Find out from...

Goose bumps, aka the “pilomotor reflex,” are part of an automatic response of a mammal’s body.  Part of this reflex’s function is to generate warmth in a cold environment.  “How does it work?” you ask.  The muscle fiber attached to the hair follicle tightens and pulls the hair straight up, which makes the surrounding skin bunch up.  The straightened hair traps a layer of air against the skin which adds insulates the body.

Goose Bumps As A Result Of Fear:

This reflex does not do a lot to help hairless mammals like humans.  However, notice how when a cat is spooked, their hair stands straight up.  This defense mechanism is caused by the pilomotor reflex.  The purpose of the hair standing up is to make the mammal appear to be larger than they are, possibly scaring the attacker away.

Everyone has heard the term "dead ends" but do you know what that really means? Let me explain...

What Are Dead Ends, Really?

Well, here’s the thing:  all hair is dead– or at least the hair you see.  The only part of hair that is alive, is the hair found in the hair follicle, below the epidermis of the scalp.  The actual hair shaft, which is the part you see, has no biochemical activity in it.  According to dermatologists, that means its dead.

The phrase “dead ends” typically refers to the ends of the hair shaft, where the hair is likely more damaged.  However, it would be much more accurate for that phrase to refer to all of the visible hair.  “Split ends” is a better way to explain the damaged ends of the hair.

How Do Perms Work?

by

When you think of a perm, you probably think of some dry, frizzled 80’s hair.  However, in reality, perms are used a lot in today’s world to add texture to hair.  Trust me, they are a lot more common than you think.  But have you ever asked yourself, “how do perms work”?  I know I used to wonder about things like that before I went to beauty school.  In this quick article, I want to teach you a thing or two about perms and the science that powers them…
