Each hair consists of about 90 percent keratin (proteins), depending on the room humidity 5-10 percent water and a remainder of pigments, minerals and lipids (fats). Keratins are fibrous proteins that give hair strength and elasticity. They form the inner and outer structure of the hair and, because of their fillament-like structure, allow it to be twisted, bent and kinked.
Why is keratin so important?
However, intact keratin is not only very elastic, but also not soluble in water. Furthermore, keratin is characterized by the fact that it is very resistant to temperature, both cold and heat. It helps the hair to withstand sun rays, winter cold and the heat of styling tools such as curling irons, straighteners and co. for as long as possible.
Hair keratin is extremely resistant to external stresses. However, constant exposure to the elements leads to slow aging and degradation of the hair keratin. Small keratins become water soluble and are more and more washed out. But also perms, dyeing and bleaching can be quite hard on the hair and have a loss of keratin as a result. Those who process their hair daily with straighteners and curling irons also ensure a slow degradation of the keratin in the hair.
In hair care, keratin is used as a high-quality ingredient that builds and strengthens the hair from the inside out. Keratin helps to restore the healthy structure of the hair. Roughened, porous hair is filled with keratin and smoothed. The hair becomes more supple, shiny and easier to style.
Straighteners and co. are the main cause of keratin degradation and loss. Therefore, you should protect your hair before styling with HItze. For this purpose, there are various heat protection lotions, leave-ins or special heat protection sprays that are enriched with keratin and care at the same time.
