Keratin pricing can look confusing — quotes range from bargain-basement to eye-watering. Here's a clear guide to what a keratin treatment really costs in the UK, and why.
The typical UK price range
Most UK salons charge somewhere between £80 and £250+ for a professional keratin treatment. Where you land in that range depends on a handful of factors below. Very cheap offers are worth a second look — a suspiciously low price can mean an older, formaldehyde-based product or a less experienced stylist.
What affects the price
- Hair length and thickness — the biggest factor. More hair needs more product and time.
- Salon location — city-centre salons typically charge more than local ones.
- Product quality — premium, formaldehyde-free formulas cost more (and are worth it).
- Stylist experience — a specialist's time and skill are part of the price.

Is it worth it?
Spread over its 3–6 month lifespan, a keratin treatment works out at just a few pounds a week — in exchange for frizz-free hair and far less time spent styling. For many clients that's an easy yes.
