Keratin Leave-In Hair Spray | Smoothing Mist for Frizz

~~£28.00~~£24.99Save £3.01

Overview

Every time you wash, dry or colour your hair, you're stripping away some of the keratin that makes it strong and smooth. Over time this leads to frizz, breakage and a rough texture that no amount of styling can fully fix. This Keratin Leave-In Hair Spray puts keratin back — not just coating the outside, but penetrating the shaft where it was lost. The result is genuinely more manageable hair that gets easier to style over time, with heat protection up to 230°C. 100ml / 230g / 3.53 oz. ECOCERT COSMOS Natural certified.

Key Benefits

Hydrolysed Keratin — broken down into smaller fragments that penetrate the hair cortex to repair internal damage and rebuild strength from within
Instant frizz control — seals the cuticle against humidity for smooth, defined strands that last all day
Heat protection up to 230°C — shields hair from blow-dryer and styling tool damage; apply before heat styling
Repairs colour-treated and chemically processed hair — replenishes the protein lost during bleaching, colouring and perming
Lightweight mist — evenly distributed and absorbs fully without leaving a heavy or greasy residue
Suitable for all hair types including fine, thick, curly and coily hair

How to Use

Step 1: Apply to freshly washed, towel-dried hair — or to dry hair as a refresh between washes
Step 2: Hold 20cm from the hair and mist evenly from roots to ends
Step 3: Comb through to distribute evenly before blow-drying or air-drying
As a heat protectant: Apply before using any heat styling tool — straightener, curler or blow-dryer
Do not rinse out — this is a leave-in treatment

Frequently Asked Questions

Do I need to rinse it out?

No — this is a leave-in treatment designed to stay in the hair. Rinsing it out would remove the keratin before it has time to bond with the hair shaft. Apply, comb through and style as normal. The lightweight formula absorbs fully without leaving a sticky or greasy residue that would make the hair feel coated.

Can I use it on fine hair without it going flat?

Yes — the formula is a lightweight mist rather than a cream or serum, which means it adds strength and control without the weight that causes fine hair to go limp. Use 2–3 sprays on fine hair (versus 5–6 on thick or coily hair) and keep the spray 20cm away to ensure even, light coverage rather than a concentrated dose in one area.

How quickly will I notice a difference in my hair?

Most people notice frizz reduction and improved smoothness from the first use. The keratin repair — which involves actual protein rebuilding inside the hair shaft — is cumulative and becomes more noticeable over 2–4 weeks of regular use. Hair that is heavily damaged from bleaching or heat will take longer to show full improvement than mildly damaged hair.

Is it suitable for colour-treated hair?

Yes — and colour-treated hair particularly benefits from keratin repair because the colouring process strips protein from the hair shaft. This spray replenishes that protein without affecting colour or causing premature fade. It is safe to use from the day after colouring once the hair has dried fully for the first time.
