I would always recommend wearing the hair from any new supplier yourself first before fitting it to any clients. This way you get to "crash test" it!! I find this really helps if clients are having any problems, as one of the biggest cause of problems seems to be aftercare routine and products - you will have confidence in what you're fitting. I've still stuck with the same hair I've worn for the last 4-5 years. I don't wear the top end hair but my hair always looks great, my clients are very happy with it, and most importantly I'm able to advise them exceptionally well regarding the aftercare. xx
