Keratin protein and disulfide bonds

Hair is made of keratin, which gives it strength and elasticity. Disulfide bonds create hair's structural stability, but they are weakened by chemical treatments, heat, and daily wear and tear.
The PROHAIR+ Keratin Series restores hair's internal strength and disulfide bonds, and gives it a healthy, strong appearance over time.

Keratin and shea butter – the combination we didn’t know we needed.

The PROHAIR+ Series for damaged hair is enriched with keratin and shea butter, a winning combination that restores damaged hair, moisturizes damaged layers, and improve hair durability.
Regular use of care products helps strengthen hair by up to 30%, even after chemical treatments.

Do you undergo regular chemical treatments at the salon? You need the Keratin and Shea Butter Series in your roster.

This series is suited for hair that has been dyed, highlighted, or straightened. The products provide intensive care to restore the disulfide bonds in hair, giving shine and reducing breakage for a restored and well-groomed look.
