Despite the name, "hair botox" has nothing to do with injections or botulinum toxin. It's one of the most effective repair treatments available for tired, damaged hair — and it's often confused with keratin. Here's what it actually is.
What hair botox really is
Hair botox is a deep-conditioning, protein-rich treatment. A concentrated formula — typically containing ingredients like keratin, amino acids, vitamins and conditioning agents — is worked into the hair and sealed in. It fills and smooths the damaged, porous areas along each strand, almost like a filler, leaving hair softer, glossier and far less frizzy.
The "botox" name is purely marketing: it borrows the idea of a smoothing, rejuvenating treatment. There are no needles and nothing injected — it's applied to the hair itself.
What it does
- Repairs internal damage and breakage
- Deeply hydrates dry, brittle hair
- Adds shine and softness
- Reduces frizz by smoothing the cuticle
- Works on all hair types, including coloured hair
Who it's for
Hair botox is ideal if your hair is dry, damaged, over-processed or dull and needs reviving. If your main goal is long-lasting frizz control and smoothing rather than repair, keratin may suit you better; if you want a genuinely straight, formaldehyde-free finish, look at nanoplasty.

How the appointment works
- Consultation to assess your hair's condition.
- Clarifying cleanse to prep the hair.
- Application of the protein-rich formula, section by section.
- Processing and sealing with controlled heat.
- Aftercare advice to extend the results.
It usually takes around 1–2 hours depending on length and thickness.
Is it safe?
Hair botox is gentle, and the formula we use is formaldehyde-free. That matters because some hair-smoothing products release formaldehyde when heated (FDA). For more, see is a keratin treatment safe?
How long it lasts and what it costs
Expect around 2–4 months, depending on aftercare — a sulfate-free shampoo and fewer washes make a real difference (see our aftercare guide). At OK Beauty Hair, hair botox starts from £75; see the full price list.
