Keratin Hair Masks

Protein repair

Keratin hair masks.
The weekly step that rebuilds structure.

Keratin is the protein hair is actually made of, so a keratin mask is the treatment for hair that snaps rather than hair that merely feels dry. A mask is where most of the work happens — longer contact time and a richer base than a conditioner — which is also why it is a once-or-twice-a-week step and not a daily one.

Using protein without overdoing it

Protein is the one area of hair care where more is genuinely not better.

1

Once or twice a week, not every wash

Hair loaded with protein and short of moisture becomes rigid and brittle in its own way — the same symptoms, the opposite cause.

2

Squeeze the water out first

A mask on dripping hair is diluted before it starts. Wring it out, apply mid-length to ends, follow the time on the pack.

3

Watch for straw

If hair starts feeling stiff and snapping more after a few weeks, cut the protein back and use a moisturising mask instead.

About this collection

Keratin is the protein hair is actually built from, which is why it is the starting point for repairing hair that has been over-processed. Bleach, permanent color and repeated heat break the internal structure down; a keratin mask puts hydrolysed protein back into the gaps, so the strand regains tensile strength instead of just feeling smoother on the surface.

Apply to clean, towel-dried hair, concentrating on the mid-lengths and ends where damage collects, and leave it for the full time on the label — protein needs contact time to penetrate. Once or twice a week is enough. Hair can be over-proteined, and the sign is hair that feels stiff and snaps dry rather than stretching.

Frequently asked questions

How often should I use a keratin mask?

Once or twice a week. Protein is the one area of hair care where more is not better: hair loaded with protein and short of moisture becomes rigid and brittle, which looks and feels like the damage you were treating. If your hair starts feeling straw-like, cut back and use a moisturising mask instead.

Is a keratin mask the same as a salon keratin treatment?

No. A salon treatment chemically smooths the hair and lasts months. A mask contains hydrolysed keratin that conditions and helps the hair feel stronger, and it washes out. Neither replaces the other.

Should I use a keratin mask if my hair is dry but not damaged?

Probably not. Dry hair is short of moisture and still stretches and recovers; protein aimed at rebuilding structure can make it feel stiffer rather than softer. A moisturising mask is the better fit.

Can I use a keratin mask on coloured hair?

Yes. Colouring and bleaching are exactly the kind of processing that costs hair structure, so protein is often what it needs. Keep to once or twice a week and watch how the hair responds.
