How much is a keratin treatment in London?

The cost of a keratin treatment in London comes down to your hair length and thickness, the type of smoothing treatment you choose, and how long the results are designed to last. Because the product used is matched to your hair, the price is set after a quick look at your hair rather than from a single flat rate. At Simon Warwick Salons in Maida Vale, we confirm the price at consultation so you know exactly what to expect.

Quick answer: A keratin treatment is priced mainly by hair length and the amount of product needed. Longer, thicker or very frizzy hair sits higher on the price list. For current rates, see our keratin straightening treatments in Maida Vale or ask at consultation.

What affects the cost of a keratin treatment

Two people can walk in with very different hair, so the price reflects the job rather than a fixed number.

• Hair length and thickness. More hair needs more product and more time, so long or thick hair costs more than short or fine hair.
• How frizzy or curly your hair is. Stronger texture can take more work to smooth well and make the result last.
• The type of treatment. A full keratin smoothing treatment and a lighter, express version are priced differently.
• Add on services. A cut or colour booked at the same time is charged separately.

In short: the more hair there is to work with, and the more smoothing it needs, the higher the price. A consultation gives you an exact figure before anything starts.

You can see current pricing on our keratin treatments page, and we will confirm your quote in person.

Is a keratin treatment worth it?

If you spend a long time fighting frizz or heat styling every morning, a keratin treatment often pays for itself in time saved. Hair dries faster, sits smoother, and holds up better in damp or humid weather. Because a good treatment lasts for months, the cost is spread across a long stretch of easier mornings.

Good to know: if you want to understand the smoothing process itself, our guide to the Brazilian keratin treatment in Maida Vale explains how it works and what to expect on the day.

How to make your keratin treatment last

Aftercare has a real effect on how long your results hold, which protects the money you spend. Use a sulphate free shampoo, avoid tying hair tightly in the first few days, and keep heat styling gentle. Our full keratin aftercare advice covers the simple steps that keep hair smooth for longer.

Frequently asked questions

How long does a keratin treatment last?

A keratin treatment usually lasts around three to five months, depending on your hair type and how you care for it. As it fades, it does so gradually, so your hair softens back rather than showing a sudden change.

Is a keratin treatment the same as permanent straightening?

No. A keratin treatment smooths and relaxes frizz while keeping movement in your hair, and it gradually wears off. Permanent straightening changes the hair structure for good. Keratin is the gentler, more flexible option for many people who simply want easier, smoother hair.

Does a keratin treatment damage your hair?

When it is carried out by an experienced stylist, a keratin treatment can leave hair feeling smoother and healthier to manage. A consultation lets us check your hair first and choose the right treatment for its condition.

Can I colour my hair and have a keratin treatment?

Yes, though timing matters. It is often best to colour first, then have your keratin treatment, and we will advise on the right order at your appointment so both look their best.
