Recovery after chemical treatment

Repair after bleaching, coloring or perming

Chemically damaged hair cannot be restored to its original state. You stop the damage and make the hair less brittle and easier to manage. Bonding and proteins fill the structure, while hydration does the rest. Honest advice keeps your client satisfied longer than a promise that isn't kept.

What happens in the hair

Bleaching, coloring and perming break the disulfide bonds and damage the keratin structure. The hair becomes porous, weak and stretchy. Keratin and proteins fill the gaps and seal the cuticle. Bonding partially repairs the broken bonds.

The right approach

• Distinguish between dry and damaged hair. Dry hair needs moisture, damaged hair needs structure. The wrong product will not solve the problem.
• Alternate between hydration and protein. Too much protein can make hair stiff.
• Always use heat protection. Heat opens the cuticle and accelerates breakage.
• Treat repair as a process of weeks, not as a one-off mask. Schedule haircuts to remove broken ends.

What it solves

Gently cleanse weakened hair with a repair shampoo and finish every wash with a conditioner that seals the cuticle. Give the hair a strengthening leave-in treatment and prevent new damage with a heat protectant for styling.

From KOOS's experience

Repair also works from the inside out. Biotin, for example in the form of gummies, can contribute to stronger hair. Keep in mind that the body first replenishes the organs. Only when those are at optimal levels will you see the effect in nails and hair. So do not expect a difference within a week, but after a few weeks. Think of it as a supplement to external care, not a replacement for it.
