- Pregnancy or Breastfeeding: Do not use. This is stated on the approved product label.
- Children: Do not use on children. This is stated on the approved product label.
- Active Scalp Conditions: Do not apply if there are irritations, lesions or abrasions on the scalp, or with psoriasis, eczema or seborrheic dermatitis.
- Fine or Thinning Hair: A volume control treatment reduces bulk, which can leave fine hair looking flat and limp. Assess carefully before proceeding.
- Henna-Dyed Hair: Henna creates a coating that blocks penetration, producing patchy and uneven results.
- Known Allergies: Do not use where there is a known allergy to wheat, soy, oat or tree nuts. This formula contains wheat and soy proteins, oat extract and macadamia oil.
- Very Light Blonde or Bleached Hair: The formula is violet. It may deposit lightly on very pale hair. Confirm the result at strand test before proceeding.
- Frequent Swimmers: Regular chlorine or salt water exposure will shorten how long the result lasts.
- Sulfate Shampoo Users: Without switching to sulphate-free and sodium chloride-free aftercare, the result will fade quickly.
- Clients Wanting Straight Hair: BTX 50 does not straighten. If a straight finish is required, use the Kerasmooth Brazilian Keratin System instead.

What Makes BTX 50 Different
Kerasmooth BTX 50 is not a straightening treatment. It is designed to reduce excess volume and frizz while the hair keeps its own natural movement and flexibility for clients who want manageable hair rather than poker-straight hair.
There is no botulinum toxin in the product and no connection to the injectable. Unlike many products in this category, which are conditioning masks, BTX 50 contains a 6% glyoxyloyl complex that reorganises the hair's surface when heat is applied.
If your client wants a straight finish, the Kerasmooth Brazilian Keratin System is the correct product, not BTX 50.

FAQs
Do I need a flat iron?
No. Flat ironing is optional with BTX 50. The treatment is applied to damp hair, processed for 30 minutes, rinsed and then dried with brushing. If a smoother finish is required, the hair may be flat ironed in 1-inch sections, 3 to 6 passes each. Never exceed 200°C, or 180°C on fine or damaged hair.
Is this kit suitable for beginners?
This kit is intended for *professional use only*. We recommend that the treatment is performed by trained or qualified hair professionals who are familiar with Brazilian keratin application techniques.
How many treatments can I perform with the 120ml bottle?
The number of treatments will vary depending on the client's hair length, thickness and the amount of product used. As a guide, a 120ml bottle can provide multiple applications on shorter hair and fewer applications on longer or thicker hair.
How long do the results last?
With the correct application and aftercare, results may last over time. Persistence depends on individual hair characteristics, application technique and post-application care. For best results, use the Kerasmooth Sulfate-Free Shampoo and Conditioner as part of your maintenance routine.
Why is the formula violet?
BTX 50 contains a violet cosmetic colourant which gives the cream its signature tone. On very pale blonde or bleached hair it may deposit lightly, which usually reads as a brass-neutralising effect. Always confirm the result at strand test, and protect towels, capes and surfaces during application.
Does it contain formaldehyde?
No. Kerasmooth BTX 50 is formulated without formaldehyde and without formaldehyde donors.
Are the accessories reusable?
Yes. The mixing bowl, sectioning clips, tinting brush, wide-tooth comb and thermal roller brush are reusable. The disposable capes and nitrile gloves are intended for single use.
What are the eco-friendly accessories made from?
The mixing bowl, crocodile clips, tinting brush and wide-tooth comb are manufactured from a *wheat fibre and PP composite*, offering a more sustainable alternative while maintaining the durability required for professional salon use.
Are there any allergens I should be aware of?
The formula contains wheat, soy and oat derivatives, macadamia (tree nut) oil, and declared fragrance allergens. Always complete a full client consultation and strand test before application
