Hi there, I am a newly qualified level 2 hair. I have been trained on using Goldwell Colour but these are so expensive and seeing as I am paying for them (for my practice on clients I am looking at using the NXT colours which are double the quantity for less cost. I have a client who has had a Goldwell Colour mix of 5NN and 5NA (Ash) my question is when I looked at the NXT colour chart against the Goldwell the NXT 5-00 appears a lot lighter and a good match looks like the 4-00 what are peoples thoughts do you think the NXT browns come up lighter Vs Goldwell and what shade would you use for the tone in NXT? Thank You
