There is many different courses out there! You've got too choose the one that suits you i would advise not to go on a two day course though as these are a waste of money as their is no way you can be taught to be a nail tech in two days! im currently training in nails and i choose the college route believeing it is the best as you have so much more practice/experience and you learn all the different aspects of nail i.e nail art, advanced nail art, gel, l&p, fibreglass - courses may vary so id check out your local college and have a look what they do it is a long course but worth it and you come out with a lot more qualifications than just doing a quick course.xx
