Reddit mentions of L'Oreal Quick Blue Powder Bleach, 16 Ounce

Yes it is. I don’t really dye roots, because I actually prefer ombre hair looks. However, many of my friends who also dye hair says it’s what they use for touching up roots. Also Sally’s (at least where I live) has it a little bit more expensive then amazon but here’s a tub of it: L'Oreal Quick Blue Powder Bleach, 16 Ounce https://www.amazon.com/dp/B000A409J8/ref=cm_sw_r_cp_api_i_5apsDb5NS3H3J

If it’s too much for that tub there’s always pouch versions available at Sally’s or Amazon which is equal to 1 scoop that comes with the tub: L'Oreal Quick Blue Powder Bleach, 1 oz (Pack of 2) https://www.amazon.com/dp/B072QRJGP2/ref=cm_sw_r_cp_api_i_PcpsDbWWME38W

Mix with 2 oz of your creme developer (I recommend Salon Care) and boom.

There is a great review on Amazon under LOreal quick blue bleach that explains a lot of the steps needed to go from brown to blonde but maybe there will be some helpful info for you. Also try youtube.

On mobile, tried to copy the link for the review, hopefully it worked. https://www.amazon.com/gp/aw/d/B000A409J8/ref=mp_s_a_1_1_a_it?ie=UTF8&qid=1494531504&sr=8-1&keywords=loreal+quick+blue+powder+bleach

After doing some researches I've decided to use exactly the same product as yours... So it's a bit reassuring you are using the same ! I've chose to buy these products:

The last part I'm struggling to understand is the immediate after bleaching process. I understand that I shouldn't stay with bleached hair, and I should use either a toner or a hair dye on my hair. Idk what colour should I expect to get (probably yellow) after bleaching. Can I put any tone of blonde in my hair in order to cover the yellow or am I oblige to use a ash colour?

I really like that colour but I'm afraid it would not really look like this over my bleached hair.

Otherwise there's this one I like but I fear that my hair won't be light enough to hold the colour.
