Keraspa is a professional haircare brand built around smoothing. Its best-known product is a formaldehyde-free keratin system, and everything else in the range either prepares hair for it, protects the result, or treats the same frizz-prone, chemically worked hair day to day. Because the range mixes salon services with take-home care, it is easy to buy the wrong thing. This guide sorts the Keraspa products ProHair carries by what they are for, so you can go straight to the right bottle.
There are five families: the Intense smoothing system (Kera 1, 2 and 3), the S+ and C+ aftercare pair, the Botox deep treatments, the Instant Hair Therapy take-home line (Rejuvenating, Replumping H.A. and styling), and a few salon accessories.
Keraspa Intense: the keratin smoothing system
Kera 2 is the treatment itself: a formaldehyde-free formula that uses Matrix Plus, a complex of cysteine amino acids, with babassu oil, wheat germ oil and vitamin E. Keraspa states it reduces curl by up to 90% and removes frizz, with results lasting about five months. It works with Kera 1 Collagen Shampoo, which cleanses the hair before the service, and Kera 3 Collagen Mask, which restores the pH and seals the cuticle afterwards. The Kera Mini kit holds all three at 60 ml for one application.
Best for: curly, very frizzy or unmanageable hair where you want months of smoother, faster styling. Our step-by-step smoothing guide explains the process in detail.
S+ and C+: aftercare for smoothed and coloured hair
S+ Sulfate-Free Shampoo is free of sulfates, salt and parabens, with a protein complex and sea-derived minerals. C+ Anti-Frizz Conditioner detangles and seals the cuticle with non-greasy emollients. Keraspa designed them to maintain its smoothing systems, and both are colour-safe. Buy them together as the S+ & C+ duo for 2.5% less.
Best for: anyone who has had a keratin, smoothing or straightening service, and coloured hair that fades fast.
Botox treatments: deep, chemical-free smoothing
Keraspa's Botox treatments are not injections and not straighteners. They are protein-and-moisture deep treatments. The two-step system is Botox I Clarifying Shampoo (vegan and sulfate-free, with coffee extract, rosemary and orange peel oil) followed by Botox II Treatment Cream (keratin, hyaluronic acid, collagen, amino acids and peptides), sold together as the Botox Duo. The Instant Hair Therapy H.A. Botox Deep Treatment balances hydration and protein with hyaluronic acid, baobab protein and hydrolyzed silk protein.
Best for: frizzy or weakened hair that needs smoothing and strength without a chemical straightening service.
Instant Hair Therapy: take-home care and styling
Rejuvenating — dry, dull, chemically treated hair
The Rejuvenating Shampoo and Rejuvenating Conditioner (formerly listed as Repair) share a shea butter and hydrolyzed rice protein complex. Vegan, gluten-free and sulfate-free, in 300 ml and 1 L. Rejuvenating duo.
Replumping H.A. — dry, brittle, maturing hair
The Replumping H.A. Shampoo and Conditioner use hyaluronic acid to hydrate the scalp and the strand and help prevent thinning and dryness. Replumping H.A. duo.
Leave-ins and styling
Kera 14 is a 14-in-1 leave-in with heat and UV protection. Infusion Lift H.A. is a daily leave-in protein infusion that works with your blow-dryer and flat iron. Kera Plus Styling Cream is a keratin blow-dry cream, Bounce-It defines curls, Blo adds blow-dry volume, Thermal Protector shields hair from irons, and Amazon Serum (babassu oil) finishes dry ends.
Quick decision guide
- Curly or very frizzy hair, want months of smoothness → Kera 1 + Kera 2 + Kera 3 (or the Kera Mini kit)
- Just had a keratin or smoothing service → S+ & C+ duo
- Frizz without a chemical service → Botox Duo or H.A. Botox
- Dry, dull, chemically treated hair → Rejuvenating shampoo and conditioner
- Dry, brittle or thinning hair → Replumping H.A.
- Heat styling every day → Thermal Protector or Kera 14
- Curls that frizz → Bounce-It Curl Enhancer
- Flat, fine hair → Blo Volumizing Spray
If you only buy one thing
If you have had a keratin smoothing service anywhere, buy the S+ and C+ pair: washing a smoothing treatment with an ordinary sulfate shampoo is the fastest way to lose it. If you have not, and your issue is everyday dryness, start with the Rejuvenating shampoo and conditioner.
Buying smart
The wash products come in 300 ml and 1 L. The litre works out cheaper per millilitre, and the Keraspa litre pump makes it easy to use. Duos cost 2.5% less than buying the two bottles separately.
FAQ
Is Keraspa's smoothing treatment formaldehyde-free?
Yes. Keraspa describes Kera 2 as a formaldehyde-free formula that smooths physically with an amino-acid synergy of cysteines.
What is the difference between Keraspa Botox and the Kera 2 smoothing treatment?
Kera 2 reshapes the hair and reduces curl by up to 90% for about five months. The Botox treatments are deep conditioning services that smooth frizz and strengthen hair without changing the curl pattern the same way.
Can I use S+ and C+ if I have not had a smoothing treatment?
Yes. They are gentle, colour-safe, sulfate-free products that suit coloured and frizz-prone hair too.
Why are some products listed as Repair elsewhere?
The Rejuvenating shampoo and conditioner are called "Repair" by some distributors. They are the same shea butter and rice protein products from the Instant Hair Therapy line.
