What bleach products do hair salons use?

[onestepat]

Any hair stylists out there ...what bleach products /toners do salons use.
I know she only uses 20 volume developer
My hair is awful and will not survive till July.

I think pretty much any bleach powder with the corresponding vol developer.
Some prefer a blue bleach powder.

I ordered last week on ultimate hair and beauty supplies and bleached my roots.
Beware though, I have a slight yellow tinge now 😬

My salon uses the professional L’Oréal and Schwarzkopf ranges

Wella Blondor is the best bleach I've come across and is used by many salons. I buy my online along with developer/peroxide and Olaplex or Innoluxe to maintain the hair's condition.
