The three smoothing options, in one minute
| Keratin treatment | Brazilian blowout | Relaxer | |
| What it does | Smooths and reduces frizz/curl | Smooths with lighter effect | Permanently breaks curl structure |
| Longevity | 3–6 months, fades gradually | ~10–12 weeks | Permanent on treated hair (regrowth needs touch-ups) |
| Damage profile | Low — modern formaldehyde-free formulas strengthen while smoothing | Low–moderate; formaldehyde concerns in legacy formulas | High — alkaline chemistry permanently alters the hair |
| Reversible? | Yes — hair returns to natural texture | Yes | No |
What is the difference between a keratin treatment and a Brazilian blowout?
Both are semi-permanent smoothing services; the practical differences are intensity and longevity. A full keratin treatment delivers deeper, longer-lasting smoothing (3–6 months vs ~3 months). "Brazilian blowout" is also a brand name historically associated with formaldehyde-releasing chemistry — a growing concern under US regulation. Modern formaldehyde-free keratin systems deliver the deeper result without the formaldehyde question.
When is a relaxer the right call?
Only when the client explicitly wants permanent straightening and accepts the trade-offs: no going back, higher damage, and a hard line between treated and new growth. For clients who want manageability and frizz control while keeping their natural pattern available, a keratin treatment is the professional default — especially for transitioning clients moving away from relaxers.
Which clients should you steer to which service?
- Frizzy, wavy, or curly hair wanting manageability: keratin treatment — e.g. Botanica for most textures.
- Very resistant or coarse hair: classic-strength keratin (Fortifying) or any formaldehyde-free system reinforced with Booster™.
- Committed to permanently straight hair: relaxer, with a candid damage conversation.
Frequently asked questions
Can you do a keratin treatment over relaxed hair?
Yes — keratin treatments are commonly used to strengthen and smooth relaxed hair and blend regrowth during transition.
Which service is safest for color-treated hair?
A formaldehyde-free keratin treatment — it's gentle on color and adds shine. Relaxers on color-treated hair carry the highest damage risk.
