Peroxide asian hair

[Clararostock]

I have a client this week who has asian hair level 2 roots and ends level 5 and she wants to be a level 4 dark brown. Should I use 9% peroxide or 6% with this please?
I was going to use 4/0 and 5/1 on roots and mids and lengths 4/0 and 5/73 6% to balance out the roots incase they lift warm with being Asian hair. Just didn't know which peroxide to use on her roots ?

9% would give too much lift at the very root. Be careful you don't get root glow.

I would use 6% on the roots
