Noooo! That's plain wrong advice.
As professionals it our duty to educate ourselves properly about the role of peroxide in hair colouring rather than making it up as we go along.
But it won't be a better colour result in the long run. If you use to high a peroxide you can get uneven colour which will fade much faster than it should.Only offered my advice from my own experience. Quite harsh but each to their own [emoji106]
