A semi-permanent hair colour treatment mask that deeply conditions as it colours, adding deep black tones for the ultimate rich, glossy finish. Expertly created with Perilla Oil & Shea Butter, this 100% vegan formula will intensify colour in black and dark brunette hair that is natural or coloured. Though not designed to cover grey hair, Black Onyx Gloss lasts up to six washes and fades gradually for the perfect semi permanent hair colour boost.

Ideal for use with The Miracle System in shades 2.0 and 3.0 to extend hair colour longevity.

Josh’s advice...clients with any lighter pieces in their hair should not apply this gloss as it can produce undesirable results. Need help with product recommendations? Contact our Client Delight team!
