I completed a nail course a few years ago and have been practising on family and friends, I am wanting to go out and work on the public and make some extra money but when ive looked at my certificate there is nothing on it apart from saying I have completed a course, it isn't certified by anyone or anything, would this be ok to work on the public or not? I am considering going doing a proper course at college which is 1 year long, the previous course i did was a 3 day course, need help please!
