I think all hairdressers have tried and tested many colour ranges until they find the ones that's right for you.
There's no right or wrong answer like with anything people have there own opinion. Just don't go for the cheapest option.
Once you've found one you're happy with learn all you can about it. The more knowledge you have the more confidence you'll have, which means more clients and more money x
Sound advice - thank you!
And thanks for all the replies, it's a bit daunting when you are starting out..i am used to Goldwell from college, but when i train in my friends salon soon i will have to use Wella and L'oreal...
