Before / After
Which Keratin Treatment Is Right for You?
Keratin cuts your styling time and keeps frizz down for months. We carry four smoothing formulas because no single treatment suits every hair type. It comes down to three things: how smooth you want it, how long it should last, and whether formaldehyde-free matters to you.
| Treatment | Best for | Appt. time | Lasts | Formaldehyde-free | Starting at |
|---|---|---|---|---|---|
| Brazilian Blowout | Less frizz, keeps natural curl | About 90 min | 10 to 12 weeks | No | $350+ |
| Keratin Complex | Thick, coarse or frizzy hair | 2 to 3 hrs | Up to 5 months | Yes | $350+ |
| Lasio Keratin | The straightest result on curly or coarse hair | 2+ hrs | 4 to 6 months | No | $350+ |
| Magic Sleek | Longest lasting, safe on color-treated hair | 3+ hrs | 6+ months | Yes | $375+ |
