What peroxide strength do you use with a level 7?

[lilymay]

At college we are learning with strengths that..

6,9,12%.
6 - 1 level, tone on tone?
9 - 2 levels lighter
12 - 3-4 levels lighters

Collegefriend wantss a light warm chocolate brown. Hair at moment is just like a dark blonde a little bit gingery were we have bleached bath the ends to make sure they dont go to dark again. As prevouis colour diarichesse chocolate brown was to dark for her liking was a 6.53 though. Nice at top/midlength, ends went to dark.
Still deciding if to use goldwell 7G or Wella Koleston 7/75.
She doesn't want it to dark she wants it like Womens Brown Long COSPLAY WIG Curly Hair Fancy Dress UK | eBay

Would it be stupid to use either of these colours with 9%? As tint wont lift tint. What would we do if we were worried about it going to dark though? Go a level 8 with 6% or level 7 with 9%?

I'm not saying this to be preachy.

However, you need to get back to the books and understand how colour works and what part peroxide plays. It's important to understand these things before messing with hair as you could damage it using too high a strength peroxide. Once the condition has been compromised, the only real option is to wait for it to grow out...

A higher strength peroxide will not cause the tint to lighten by a base shade.

Also, the 'rules' on levels of lift that you have learnt will apply to the colour house your college uses (Goldwell?) but they will be different with other colour houses/brands so you must always check the manufacturers instructions carefully.

If you are really enjoying learning about colour, there is a good book I can recommend called
The Colour Book: The Official Guide to Colour for NVQ Levels 2 & 3
It's worth the investment particularly if you think you might go on and study level 3 and colour correction in the future.

I hope this has helped.
