Siyah
I’ve been using this hair concealer for a few weeks now, and I’m genuinely impressed. It blends seamlessly with my natural hair color, covers thinning spots effectively, and lasts all day without rubbing off (EVEN SWIMMING) although it doesn’t quite last 9 days.. more like 3-4. To apply I get my partner to basically paint it on with a little hair dye brush. It gives a fuller, more confident look without feeling heavy or fake. Definitely a great solution for anyone dealing with thinning hair or visible scalp areas.

Dont trust this company
Dont trust this company. their website terms are all in French, they are using fake TrustPilot scores on their websites too. Also if you need to make a return they will ask you to send the horrid items back to CHINA! They have no physical address in France, no contact number, no support service and they dont respond.

Absolutely rubbish, and the worst customer service.
This stuff is like a black tar that doesn't come off. I used it, reacted and then had to use thinners to take it off. Leaves patches and thick glue like residue. I've contacted them for a refund under their 100% satisfaction guarantee with no response. I've had to go through my credit card issuer for a charge back to get my money back. Avoid like the plague!!!
