advise on using schwarzkopf IGORA VARIO BLOND needed

[Senorita_ee]

Hi everyone!

Manufacture's instruction for IGORA VARIO BLOND bleach powder states that it can be mixed with IGORA ROYAL COLORIST'S COLOR & CARE DEVELOPER with a strength MAXIMUM of 9%. My question is - can I use it with 12% developer? Why instruction says maximum 9%?

Thanks!

hi,
ive used it with 12%, with no adverse effect to the hair, though i stayed very close to client and kept checking, hope this helps,

TBH if the manufacturers instructions say not to use it with 12%, I wouldn't go against them. X

I use 12% with this bleach and also the Wella one, had no problems with either. Just make sure you keep checking it!
