Black Diamond straightening in Rabat — Red & Gold

Black Diamond straightening is our premium straightening service. Two variants: Red at 1,000 MAD, Gold with diamond powder at 1,500 MAD. Formaldehyde-free, lasts up to 6 months.

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.

Why Black Diamond?

  • 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
  • 100% formaldehyde-free

For which hair type?

  • Frizzy to unruly afro-textured hair → Red or Gold
  • Bleached or colored hair → Red or Gold
  • Discerning women who have already tried other straightenings → Gold

3 to 3.5 hours of complete care, in 6 steps:

  1. Personalised consultation (variant choice)

Frequently asked questions

What's the difference between Black Diamond Red and Gold?+

Two Black Diamond variants. **Red** (1,000 MAD): the standard version, suitable for all frizzy hair types, including colored or bleached hair. **Gold** (1,500 MAD): the premium pure diamond-powder formula, mirror finish, maximum durability. Our hair consultation determines the most suitable variant.

How long does Black Diamond last?+

4 to 6 months on average, sometimes more with the Gold variant and rigorous maintenance.

Is Black Diamond suitable for bleached hair?+

Yes — it's even one of its strengths. The **Red** variant is specially adapted to colored or bleached hair. The formula rebuilds fragile fibres.

Black Diamond Gold at 1,500 MAD: why this price?+

The **Gold** formula contains pure diamond powder and a premium concentration of Brazilian smoothing actives. The mirror finish, maximum durability (up to 6+ months) and reinforced fibre justify the price. It's our top-of-range straightening.

On which hair does Black Diamond give the best result?+

On **frizzy to unruly afro-textured hair**, on **bleached or heavily processed hair** (Red variant), and for women who have tried other straightenings and want to upgrade. On fine and natural hair, Brazilian tannin (500 MAD) is largely sufficient.

How long should I plan at the salon for Black Diamond?+

Plan 2 h 30 to 3 h 30, including diagnosis + preparatory shampoo + application + 30-45 min hold + flat iron + finishing. Longer than standard Brazilian because the active concentration requires more precise hold time.

Can Black Diamond and coloring coexist?+

Yes: color **before** Black Diamond (or wait 15 days after). Black Diamond Red is specifically adapted to colored hair. Our colorist will propose the ideal combination during the consultation.

What maintenance for a Black Diamond in Rabat?+

Same as classic Brazilian straightening but even more important: sulfate- and salt-free shampoo, weekly hydrating mask, anti-limescale shower filter (Rabat water), no sea/pool water without immediate rinse. A Hair Botox every 2 months extends durability.

First straightening: Black Diamond or start with something else?+

For a first straightening, we recommend **Brazilian tannin (500 MAD)**: lets you discover the effect, check your fibre tolerance. Once familiar, you can switch to Black Diamond. But if you already know what you want, go for it.

Is Black Diamond truly formaldehyde-free?+

100% yes. Like all our straightenings, Black Diamond complies with European standards (no formaldehyde, no MEA, no banned aldehydes). Ask for the technical sheet at the salon.
