ACTIVE INGREDIENTS · KERATIN

Protein support for hair that has been through a lot.

Hair fibre is composed almost entirely of keratin protein. Heat styling, chemical treatments, and mechanical stress deplete the protein structure and leave hair porous, rough, and prone to breakage. Hydrolysed keratin in OVESSI hair formulas delivers smaller protein fragments that bind to the damaged cuticle, smooth the surface, and reduce porosity. The result is hair that feels denser, softer, and more manageable without a heavy, coated texture.

FREQUENTLY ASKED

Keratin questions

How does hydrolysed keratin differ from a keratin treatment?
A salon keratin treatment uses high heat to bond protein to the hair cuticle for weeks. Hydrolysed keratin in a leave-in or rinse-out formula provides ongoing, wash-by-wash protein replenishment without the formaldehyde-adjacent chemistry of some salon treatments. The benefit is cumulative with consistent use.
Can I use keratin on fine hair without weighing it down?
Yes, when the formula is designed for fine or normal hair. Hydrolysed keratin at lower concentrations fills gaps in the cuticle without adding visible weight. OVESSI hair formulas balance protein with lightweight conditioning agents for a finish that adds strength without compromising movement.
How often should I use a protein treatment for my hair?
Once a week to once a fortnight for hair that is regularly heat-styled or chemically treated. Over-proteination can make hair feel stiff and brittle. Alternate protein treatments with moisture-focused conditioning for a balanced approach.
How do I know if my hair needs more protein or more moisture?
Hair that stretches and then breaks needs protein. Hair that feels dry, rough, or brittle without snapping needs moisture. Hair that feels both stretched and dry may benefit from a balanced treatment that addresses both. Start with one and observe the response before adjusting.
