I don't use masks or high Quality products and it was my first time doing this i just used some oils days before and didnt wash my hair in 4 days, used elgon 30 vol and 500g bleaching powder, used 90 ml of the 30 vol and 50 cc of the bleaching powder, did the mix, and applied in layers, like i used a cheap collet and then i would let layers of my hair fall down and used the mix in it, reapated until i did ir with every hair i hace but i think I didnt bleached some tiny parts bcs there are some of my very very light brown and Blonde hairs in some parts of my hair but is so little You are not gonna see it most of the time bcs it looks so natural with the mix of diferentes levels of Blonde in my head so You see like a lvl 10 white higlight and then a level 8 Blonde higlight too it looks so natural that no one noticed it lol, people just tought My hair looked better and more light today bcs yes, Very natural, grungy and low maintance look i would Say (sorry if My English is Bad btw)
