Black Diamond straightening — absolute excellence
Black Diamond is a premium Brazilian brand recognised worldwide for its straightening. At OLM Beauty Rabat, we are one of the rare salons offering the range in two variants — well beyond our Brazilian tannin straightening in terms of finish quality and durability.
The 2 Black Diamond variants
Black Diamond Red — 1,000 MAD
The standard version of the range, at 1,000 MAD: it suits all frizzy hair types, from natural hair to colored or bleached hair. Radical straightening, smooth and shiny finish. Its formulation preserves the color while smoothing, making it ideal after balayage or coloring as well as on untreated hair.
Black Diamond Gold — 1,500 MAD
Our premium pure diamond-powder service. Maximum concentration of Brazilian smoothing actives, incomparable mirror finish, lasts up to 6+ months. For women who want the best.

- Higher active concentration than Brazilian tannin straightening
- Two variants to suit your fibre (Red, Gold)
- Deep reconstruction of the capillary fibre
- Lasts 4 to 6 months, up to 6+ months with Gold
