How Long To Leave Bleach In Hair 30 Vol

How long should I take 30 volumes? Bleach my dark hair to get rid of blonde hair? 3

Well, my hair is naturally black, but lately I have a variety of dark colors and I want to be blonde! First of all, I don't think the bleach people are referring to is pure hydrogen pixels, so it should be a lot. I try to avoid bleaching because it really damages your hair, but using Loreal's Perfect Blonde Mom Bleaching Cream makes my hair darker orange. I have heard that 20 or 30 volumes. Bleach is great for 40s hair because it is less thick or thin, but you have to leave it on longer than 40 so I would be happy for someone to tell me how long to leave it on 20/30 Should. My hair should be curly. . Blonde color. I realized that after the first bleach, my hair would not get the perfect color I was looking for, but if it was light enough then pale would be fine too!

Thanks in advance!

I don't have a perfect answer I'm sure but I made it myself. And I brought the bleach to 30 volumes for 35 minutes. I got scared and washed it. Then I tried 35 minutes on one of the 30 flights. And the color is light, but I painted it with a purple base and it helps. Still not satisfied, I cleaned it up after 4 weeks to finalize. Previously I used 30 volumes for 30 minutes and now my roots are at level 10 and my intersection / level is at level 8. So I applied some light gray blonde hair to try to get more color. Gets gray. Instead of immediately lightening my center / bottom, I've just added a little Vela 9NG with Developer 10 to flatten the top a bit and remove the light color. So beware of our roots, don't do that first =)

Don't panic like me and let go very soon =)

I don't know if I will! The colors are very woven!
