# Keratin Treatment

> Keratin treatments are semi-permanent chemical processes that smooth and strengthen hair by applying a liquid keratin formula and sealing it with heat.

## What is Keratin?

Keratin is a fibrous structural protein, making up the primary component of hair, skin, and nails. In hair, keratin forms the protective outer layer, the cuticle, and the inner layers, collectively known as the cortex. It provides strength, elasticity, and protection against damage. When hair is healthy, the keratin layers are smooth and tightly bound, resulting in a shiny, resilient strand. Damage from heat, chemical processes, and environmental factors can break down these keratin bonds, leading to frizz, dullness, and breakage.

## What is a Keratin Treatment?

A keratin treatment is a semi-permanent chemical process designed to smooth and strengthen hair. It involves applying a liquid keratin formula to the hair, which is then sealed into the hair shaft using a flat iron. The treatment aims to replenish lost keratin, fill in porous areas of the hair cuticle, and create a smoother, more uniform surface. While often referred to as a
