How much does hair botox cost?

A hair botox treatment in the United Kingdom typically costs around 99 to 300 pounds as reviewed in June 2026, with short hair often nearer 150 pounds and long or thick hair towards the top of the range. London salons may charge a little more given demand, and the effect usually lasts around two to four months before fading gradually.

What you are paying for

Despite the name, hair botox has nothing to do with injectable botox. It is a conditioning treatment that coats and fills the hair shaft with ingredients designed to smooth, strengthen the look of damaged strands and add shine, then is sealed with heat. The result is softer, glossier, more manageable hair.

It suits people with dry, frizzy or damaged hair who want a smoothing, conditioning boost without harsh straightening. It is often chosen as a gentler alternative to a keratin treatment, and a good stylist will advise which fits your hair and goals.

Your fee covers the stylist's time and the product, and because the treatment involves washing, applying, processing and styling, it takes a couple of hours. Longer and thicker hair uses more product and time, which is why quotes rise with hair length.

The honest cost picture

Hair botox pricing tracks hair length and thickness, the product range used, and the salon's location and reputation. City centre salons sit at the higher end, and package deals can lower the cost.

What drives the price

Hair length and thickness are the main factors, since more hair needs more product and a longer appointment. The product range used matters, with premium lines costing more, and the salon's location and reputation count too, so a city centre or well known salon usually charges more. Package deals or quiet hour appointments can bring the price down.

How cities differ

London and city centre salons tend to charge a little more than salons in smaller towns, reflecting demand and running costs. The useful question is which product range is used and whether aftercare is included, since that shapes both the finish and how long it lasts. Compare the product and the stylist's experience rather than chasing the lowest headline price.

How it compares to the alternatives

Hair botox is most often compared to a keratin treatment. Both smooth and add shine, but hair botox leans towards conditioning and repairing the look of damaged hair, while keratin focuses on frizz control and manageability, which you can weigh up on our keratin treatment cost guide.

For colour rather than smoothing, treatments such as balayage serve a different purpose, and many people add a conditioning treatment to a colour appointment. Hair botox is about softness, shine and the look of healthier hair rather than changing colour or permanently altering texture.

What to expect and aftercare

There is no medical downtime with hair botox, but aftercare protects the result. Salons often advise a sulphate free shampoo and washing less frequently, which helps the smoothing and shine last longer, and you can usually return to normal styling straight away.

The honest expectation is softer, smoother, shinier hair that looks healthier and is easier to manage, lasting around two to four months and fading gradually. It does not permanently repair damage or change your hair type, and results depend on your hair condition and how well you follow aftercare.

Getting value without cutting corners

Value comes from an experienced stylist, a good product matched to your hair and sensible aftercare rather than the cheapest deal. A very low price on the wrong product can fade quickly or leave hair looking limp, so ask which range is used and why it suits your hair.

Choose a salon that asks about your hair condition and history and tells you honestly whether hair botox or a keratin treatment is the better fit. Pairing the treatment with recommended aftercare is often what makes the result last towards the longer end of the range.

Is it worth it, and when to wait

Hair botox is worth it for someone with dry, frizzy or damaged hair who wants a smoothing, conditioning boost and glossier, more manageable hair for a few months. For that person, the softer finish and easier styling can be well worth the cost.

It is worth thinking twice if your hair is already healthy and sleek, or if you expect permanent repair or straightening, since the effect is temporary and cosmetic. Setting that expectation upfront avoids disappointment.

It also helps to time it sensibly. Because the effect lasts two to four months and fades gently, many people book ahead of a holiday or event and repeat a few times a year. Following the recommended aftercare and washing less often stretches each result, which improves the value across the year.
