I've been having Bio on my nails for the last 7 years non stop, and sadly my friend that used to do my nails was diagnosed with cancer and died in august last year. When i finially removed the gel (5 weeks after she did them) they were still strong and healthy underneath - even after 7 years of being covered!
I then did my Bio training in november and take my practicle exam next week (eek!) It is quite expensive to do the training course (more so for me as i didn't have a basic manicure certificate) but it was well worth it, and you get a decent starter kit with uv lamp included in the training pack price x
I am so sorry to hear about your friend :hug: That's great you didn't any damage to your nails after 7 years - she must have been a good tech did she buff at all? Good luck with your exam next week I'm sure you will ace it... At least you've got all those years behind you of watching your friend!!
