As a nail tech who has made the transition 2 years ago from fibre glass to Bio gel im looking to add a gel polish to my range of services and im really not sure which to go with. Obviously everyone screams about Shellac but is that because it was one of the first? Is it the best?? I hear lots of you talk of Gelish, is it better??? The other problem is i see gel polish manicure as a high cost when a fullset of Bio gel isnt far off the same price and also gives strength and reinforcement to the nail which the gel polish doesnt, so whats my selling point??? Advice from really users please x
