Brazilian straightening uses keratin for an ultra-smooth effect lasting 4 to 6 months, ideal for frizzy to coily hair (3C-4C), priced 150-400 €. Indian straightening uses tannin for a natural smooth lasting 3 to 5 months, ideal for wavy to curly hair (2A-3B) or damaged hair, priced 120-350 €.

Choosing between an Indian straightening and a Brazilian straightening means choosing between two philosophies of smoothing care. Both techniques are professional, thermo-activated, and formaldehyde-free at ULTRALISS — but they do not meet the same expectations.
Brazilian Straightening
Pure smooth effect, maximum discipline
Ideal for very frizzy / coily hair (3C-4C) or very voluminous hair.
Indian Straightening
Natural smooth, preserved movement
Ideal for wavy to curly hair (2A-3B) or damaged hair.

The Formula Difference
Brazilian straightening relies on hydrolyzed keratin, which rebuilds the fiber and seals the scales for an ultra-smooth finish. The JANNA COSMETICS technique uses premium formaldehyde-free keratin, safe and professional.
Indian straightening, on the other hand, uses vegetable tannin derived from plants like acacia. Tannin coats, tightens, and repairs the fiber without forcing its nature. The result: curls remain visible but tamed, frizz disappears.
Duration and Hold
- Brazilian: 4 to 6 months with appropriate maintenance (sulfate-free shampoo + post-straightening mask).
- Indian: 3 to 5 months. The hold is slightly shorter but regrowth is more discreet because the effect is more natural.

Which Texture for Which Straightening?
Wavy Hair (2A-2C)
→ Indian Straightening. Tames frizz without a rigid effect.
Curly Hair (3A-3B)
→ Indian Straightening to maintain movement, or light Brazilian for a straighter effect.
Frizzy Hair (3C-4A)
→ Brazilian Straightening. Disciplines the hair, reduces volume, lasting smooth effect.
Coily Hair (4B-4C)
→ Brazilian Straightening primarily, with careful preparation.
Damaged / Color-Treated Hair
→ Indian Straightening with tannin, more repairing and gentler on weakened fiber.
Post-Straightening Maintenance
In both cases:
- Sulfate and salt-free shampoo
- Nourishing mask once a week
- Avoid chlorinated pools and seawater for the first 15 days
- Tie hair as little as possible for 72 hours after a Brazilian straightening
Can I do straightening at home?
No. ULTRALISS products are professional, thermo-activated at 200-230°C, and require a prior fiber diagnosis. An incorrect application can burn or break down the hair. We consistently recommend a partner salon or an ULTRALISS Academy training for professionals.
Conclusion
There is no “best straightening” — there is the straightening adapted to your texture and your lifestyle. Brazilian for discipline, Indian for softness. And if you are unsure, a free diagnosis is offered at every ULTRALISS partner hairdresser.
