“I want to straighten my hair, but which one should I choose?” That’s THE most common question at OLM Beauty Rabat. Tannin, keratin, Brazilian, Black Diamond: four treatments, four different results. Here’s how to choose based on your hair and your goal.
The basic rule: straightening intensity
The four treatments don’t straighten with the same intensity:
| Treatment | Effect | For whom |
|---|---|---|
| Tannin treatment | Gentle discipline, keeps movement | First straightening, lightly frizzy hair |
| Keratin treatment | ”Wake-up blowout” effect, anti-frizz | Keep your shape but without frizz |
| Brazilian straightening | Straightens 80-95%, mirror shine | Real long-lasting straightening |
| Black Diamond | Radical straightening, mirror finish, most durable | The smoothest, longest-lasting result |
1. Tannin treatment — the gentlest
Based on plant tannins, it’s the ideal entry treatment for a first straightening. It disciplines without radically transforming. Perfect if you have lightly wavy hair and want to test the concept without commitment.
2. Keratin treatment — the permanent blowout effect
Keratin recharges the fibre and gives the effect of a blowout from the moment you wake up. It reduces frizz while keeping your natural movement. Ideal for those who love their shape but are bothered by frizz.
3. Brazilian straightening — the real long-lasting straightening
Brazilian straightening (formaldehyde-free with us) straightens 80 to 95%, gives a mirror shine and lasts 4 to 6 months. It’s the most popular choice for a smooth, natural and durable result.
4. Black Diamond — the premium
Black Diamond is our most upscale formula: a radical straightening, a spectacular mirror finish and the longest hold (4 to 6 months and more). For those who want the smoothest possible result, no compromise.
What if my hair is damaged?
If your fibre is weakened (bleaching, balayage, heat), don’t straighten right away. Start by repairing with a Hair Botox or a damaged hair treatment cure, then straighten on a healthy fibre. That’s the guarantee of a breakage-free result.
