not harsh on my hair and bleaches quickly. Bought 4 boxes. We'll surely order again next time.
Didn't make my hair so damaged. My hair is still soft after a week (but with continuous use of conditioner) and it doesn't have the burning sensation when it touched my scalp and skin on my ears and neck. It does have a strong smell (just wear a mask when applying so you don't get to inhale some of the chemicals). The length of my hair is up to my breast so it's about 5-6 boxes of the bleach to cover up everything. It's a bit pricey but still worth it.
The reviews say you need more than 1 box to cover your hair depending on its lenght. I have long hair and the maximum amount of prod we could buy is only 1. Which is inconvenient because the shipping fee costs so much
Bleaches hair quickly but not too harsh on the hair. I have a thick super black hair so I let the product stay for about 45 minutes.
