What Is Keratin Hair Treatment?

Keratin hair treatment is a semi-permanent hair straightening treatment. This chemical process smoothens and adds shine to your hair by filling in the gaps where the keratin (a fibrous protein found in hair) has been depleted. This popular treatment is also known as Brazilian blowout and is guaranteed to give you free-flowing, lustrous tresses. It is targeted more toward frizz control and smoothening the hair than straightening it. Generally, hair straightening treatments break the protein bonds in the hair, but keratin hair treatment does not break the bonds. Instead, it coats the hair like a conditioner and helps restore hair health, reduce frizz, improve manageability, reduce styling time, and seals the hair cuticle without changing the hair structure permanently. Furthermore, this hair treatment repairs hair breakage and damage and rebuilds its strength, which makes your hair smoother and shinier.
