The 20 best keratin shampoos and conditioners for 2021

When we are talking about healthy hair, you’ve probably heard the word keratin and everyone else hair care products which contain the ingredient. But you may not be completely sure what exactly it is and what it should do. So I decided to help everyone and ask the experts what it was all about.

It turns out that our skin, hair and nails are made of keratin, which is a structural protein. “Hair consists mainly of keratin, as well as some proteins associated with keratin or KAPs, lipids and several other minor ingredients such as minerals and water,” explains Suveen Sahib, founder of K18 Hair. “Keratin exists in several forms. The key to hair strength and elasticity lies in alpha keratin, which forms long, spirally intertwined fibers in the hair follicle. Think of it as a rope inside the hair. They run the length of the hair. And provide this resistance, which contributes to the tensile strength of the hair. “

Celebrity hairdresser, trichologist and founder of Act + Acre,, Helen Reeve, adds that keratin nourishes the hair by filling in the gaps in the cuticle and is often used in hair care to help fight breakage.
