Overview
Keratin Hair Treatment at a Hair Salon
Salon keratin differs from a home kit in three ways: the solution concentration, the flat-iron temperature control, and the strand test that happens before either. All three are why salon results last months and kit results last weeks.
The Strand Test
A small hidden section is treated first. The technician checks how the hair responds — how much smoothing, whether the cuticle seals, whether there is any adverse reaction. It costs ten minutes and prevents an irreversible mistake.
