Brazilian Hair Smoothing: the complete guide
Composition, protocol, duration, price and risks — broken down by the manufacturer
Brazilian smoothing is the most requested salon smoothing treatment. Formaldehyde-free in Europe since 2018, it combines glyoxylic acid, keratin and coating actives. This guide explains what's inside, how it's applied, what it costs, how long it lasts and how to launch your own white-label range.
Brazilian smoothing composition: actives & dosages
Glyoxylic acid
The main smoothing active. It reorganises keratin disulfide bonds under heat (220 °C) without releasing formaldehyde. Typical dose: 4-8 % depending on target intensity.
Hydrolysed keratin
Rebuilds the fibre, fills porous zones and improves shine + touch from the first application.
Amino acids & collagen
Cysteine, arginine, marine collagen: reinforce fibre cohesion and extend smoothing hold.
Plant oils (argan, açaí, coconut)
Nourish, seal cuticles and deliver the signature mirror-shine effect.
Film-forming polymers
Form a flexible film that disciplines the fibre, reduces frizz and protects against humidity until the next wash.
0 % formaldehyde, 0 % free glyoxal
Compliant with EC Regulation 1223/2009, CPNP-notifiable, usable in EU salons without restriction. That's our lab commitment.

FAQ — Brazilian smoothing
How long does a Brazilian smoothing last?
Between 3 and 5 months depending on hair type, shampoo frequency and aftercare. On fine hair, expect 3 months; on thick curly hair, up to 5 months. A sulfate-free shampoo extends hold by 30-40 %.
How much does a Brazilian smoothing cost?
In-salon expect $170 (short hair) to $400 (long thick hair). Material cost per service is $9-17, giving salons ~90 % margin. White-label manufacturer pricing starts from €35 excl. tax per litre at 200-unit MOQ.
Does Brazilian smoothing damage hair?
No, if it's formaldehyde-free and properly applied. It coats and rebuilds the fibre via keratin. Damage almost always comes from poor protocol: temperature too high, product on scalp, or formulas containing free formaldehyde / glyoxal.
What are the risks of Brazilian smoothing?
Risks disappear with an EU-compliant formaldehyde-free formula. Avoid: pregnancy (precaution), severe asthma (airway irritation), hair bleached over 30 % (strand test mandatory before application). Always do a 48 h patch test.
Which shampoo after a Brazilian smoothing?
A shampoo free of sulfates and sodium chloride. Sulfates open the cuticle and strip smoothing actives within weeks. We supply a matching post-smoothing shampoo, white-label.
Can I colour my hair after a Brazilian smoothing?
Yes, but wait at least 15 days after smoothing. Ideal: colour 2 weeks before smoothing — the colour holds better and smoothing seals it. Never combine bleaching + smoothing on the same day.
Does Brazilian smoothing work on coily hair?
Yes — it's the ideal target. On coily hair (type 4), it reduces volume by 70-90 % without breaking the root. Expect 2 applications 4 weeks apart for optimal results.
