Great book

I own many books about hair. But the last I bought is :
Hair structure and chemistry simplified.

It's made for students , but we find in it many informations
about the structure of the hair, what happens to it
when we perm, color, bleach, shampoo, cut and so on.
It contains many electronic images.

As a long hair lover and owner, I really love to know
maximum detailed information about hair and treatments.
I developed my love for hair with your site and it continues.

New, the book is at high price. But I found mine, used, at
adebooks.com

It was just to share it with those who are maniacs like me
about hair knowledge.
Hope it will be useful for some.

No, I'm not a trainee trichologist but it seems to be an interesting career.

Like I said on abebooks.com, the
price is as low as $10.00 for used book . 286 pages ( in USA )
But you don`t live there as I see...

For exemple, in the book, they show that the tip of the hair
is rounded 6 months after being cut. It's already visible after a month.
It has sharp ragged edges when it's freshly cut.

They explain that the hair cuticles close in mild acid solution.
It's why it's good to rinse with diluted vinegar (acetic acid) or
lemon ( citric acid). It removes the soap and minerals in water.

In alkali solution, the cuticles open up and let the solution
penetrate to the cortex. Damage may be caused. It's
why coloring, perming, bleaching is rough for the hair.

The hair cortex is made of protein chains , but
there are some amino-acids free . So, it's useful
to use a protein treatment to help the hair keeping
his moisture, because these free amino-acids hold the moisture
in the cortex at a desirable level of 10 %.

The resistance of the hair is due to his high sulphur
content (4-8 % ). Raw eggs are rich of it.
In an other book, the recipe the man recommends to drink daily is :
3/4 cup of milk with 1 raw egg and a tablespoon of wheat germ oil,
and some other things. (emulsified in blender). A little bit difficult to digest.
( The book is : Healthy hair and common sense - Dale Alexander)
The book is for men who have trouble with baldness, but his
diet and informations are good for women like me, too.
