It is good to use only with 2% 7 vol because you may get a burn on your scalp and your hair may get damaged as it is very strong, that's why there are 9 levels of lightening. Use a low developer and leave it on for a little longer if your hair can handle it, and not a strong developer where you end up with melted hair in your hands with the 9 volume. If you don't know how to use such products, don't do it. Just like chlorine on clothes, think of decolorizer as chlorine for your hair. Be very careful!

Use with its own oxidizer, after 10 minutes it started running like water, the decapage swelled and burned the ends of the hair! The aluminum foil burned and the head was burning.
Terrifying experience

It is a very good product, my hair did not suffer. I was afraid to leave it on for too long and I didn't achieve the exact lightening I wanted, but next time I will leave it on for longer. I would definitely buy it again

good quality bleach podwer, it does lift from natural black virgin hair to amost a level 10, with 15 vol developer. higher developer will just burn the hair and not lift more. its a great product for virgin hair, but might be a little harsh for already damaged hair

9 levels of lift means happiness for me.
The previous 7-level bleach is good, but for this result you need a 9-level one. And if necessary, for touch-ups, I use a 20-volume developer.
However, you will need a protection system inside the bleach. It is possible. It also has its own scoop inside.

I haven't tried any other brand, except for some very cheap ones that I used when I was younger, but I think this one is really good! Of course, I also use Olaplex, so that might play a role too

Excellent hair decolorizer. Protects the hair. After two uses with a week's difference between them, the hair is soft and not dehydrated at all.

In combination with the Blondme Developer 30 Volume, my hair went from dark brown to quite light blonde in 2 applications. I left 5 days between the two bleaching sessions and my hair is still soft and not damaged at all (it's definitely not like before, but the difference is very small compared to the intervention that was done). I highly recommend it!
