Straightening or hair botox: what are the differences?
A professional straightening treatment lastingly changes the shape of the hair and reduces volume. Hair botox is a deep treatment: it repairs and tames the fibre without removing the curl. For a client who wants to lose volume, choose straightening; for damaged, dull or porous hair that keeps its movement, choose hair botox. Both services alternate well over a year.
What is professional straightening?
Straightening is a technical service that transforms the shape of the hair: volume is reduced and the hair becomes smoother and easier to style. The sequence published on our category pages is the same across families: preparation shampoo, drying to 80 %, section-by-section application one centimetre from the roots, processing time, full drying, then the iron at the temperature stated by the formula.
ULTRALISS carries five families of straightening — Indian, Brazilian, Korean, French and tannin — all formaldehyde-free, in professional sizes.
What is hair botox?
Hair botox is not an injection: it is a professional deep treatment for damaged, dry, porous or dull hair. It works on the fibre, brings back suppleness and shine and tames the hair without relaxing the curl.
On ULTRALISS, hair botox has its own universe, with categories by technique (Indian, Korean, French) and references in professional 1 kg sizes.
Straightening or botox: how to choose?
The question to ask in the salon is simple: does the client want to lose volume, or to recover a healthy fibre? Straightening answers the first need, hair botox the second. Neither service is better than the other — they answer different needs.
On very damaged hair that still wants straightening, a hair botox beforehand helps work the fibre before considering a gentle treatment. Conversely, straightened hair can benefit from a botox during aftercare, alongside a sulphate-free shampoo and a weekly mask.

Each universe gathers its own categories and brands. Here are representative references from both families:
Frequently asked questions
- Does hair botox straighten the hair?
- It tames the fibre and reduces frizz, but it does not lastingly change the shape of the hair the way straightening does: the curl is preserved.
- Can the same client have both a straightening treatment and hair botox?
- Yes, the two services alternate over the year. Hair botox is often used to work a weakened fibre, straightening to reduce volume.
- Which service for damaged hair that keeps its movement?
- Hair botox: it is designed precisely for dry, porous or dull hair that does not need to lose its curl.
- Do straightening treatments and botox contain formaldehyde?
- No. The formulas distributed by ULTRALISS are formaldehyde-free and compliant with European regulations.
- What aftercare follows each service?
- In both cases: sulphate-free shampoo, a weekly mask and a heat protectant with every blow-dry. Aftercare directly determines how long the result lasts.
