cortex
no, nothing will
It slightly damages it.
The cuticle, the cortex and the medulla.
I have a cortex straightener, and I find that it rips at my hair, as well as even if I have the heat control at the lowest it doesn't stop heating so It tends to burn my hair.. I had a cheaper straightener before, called a biosilk and my hair was always really soft and since I got my cortex my hair is destroyed..
Hair gets it's color from melanin pigments found in your hair's cortex.
The main part of the hair shaft is located in the cortex layer. This layer is composed of keratin and contains the pigment that gives hair its color. The cortex also determines the strength, elasticity, and texture of the hair.
Of course, the chemicals in the products we use to dye our hair is very drying to our hair which damages it, just not as worse as bleach but still damages it.

Structure of the hair shaftYour smooth, glossy hairs have a more complicated structure than you might think. Each one can be compared to a tree: all its moisture lies in its centre, behind a tough outer layer of protective bark. If the 'bark' of the hair is well looked after the whole hair remains in good condition. If the 'bark' is stripped off to expose the centre the hair may break.The centre part of the hair, called the cortex, makes up most of the hair shaft. It is the cortex that gives hair its special qualities such as elasticity and curl. The cortex is packed with strands of keratin, lying along the length of the hair. These keratin fibres are made of the low-sulphur keratins, and are compressed into http://www.pg.com/science/haircare/hair_twh_14.htm
