Please note that the following smoothing systems are Formaldehyde-free.
Keratin is a natural protein found in hair; it acts as a protective shield against humidity, the primary cause of frizz. Over time, hair can lose keratin from sun exposure and styling products. Keratin smoothing treatments restore the shine, strength, smoothness and elasticity of the hair.
A smoothing treatment seals the hair cuticle with a coating of protein that eliminates frizz, making hair soft and shiny.The process can take a few hours depending on hair type, length, and fullness.
