Schwarzkopf ケラチン色パーマネントヘアカラークリーム、1.0ブラックオニキス（梱包が変更になる場合があります）

Best hair dye for black hair, it last longer compared to Garnier product, in the 1.0 true black color. it last around 2 months +++ and the dye is easy to remove from skin, you need a good wash under the shower, around 15 minutes wash you hair and your skin, the dye on skin will vanish fast. I really like this dye, you get a special application for your hair points, its called Serum, it is really healing the hairs in the process of dyeing them.

Great hair color! The Onyx Black is rich and shiny, and it left my hair soft and strong with no dryness. Easy to use and long-lasting results. Highly recommend!

I was a L'Oréal girl until L'Oréal stopped making permanent hair colour. They call it permanent, but it washes out. It didn't used to do that. Black never washed out - ever. They also stopped putting expiration dates in the boxes. I started using this. It washes out, but it takes a lot longer, so my colour stays fresher longer. If you're like me and don't trust no one with your hairs this is the best brand to do your own. I've been using it a few years now. Nice colour and better staying power. It's not harsh on the scalp or hair.

Super recommended, it leaves your hair super black

Best box dye in my opinion. I have very thick hair and most box dyes do not take well to my hair. (Washes out after only a few weeks). Aside from having my hair done professionally this is probably the best quality box dye.
