I don't think there are too many hairdressers setting up mobile or working from home or chair renting businesses that have been on a couple of one day courses and then learnt on clients by trial and error?
All the hairdressirs that I have met have been through college or an apprenticeship. I've heard of girls who didn't complete training going mobile or WFH but from clients you tell me "this is why she's cheap" and they know there's a difference in knowledge and standard of service. These ladies mostly do trims, kids and same same regulars.
In beauty there is a lot of professional jealousy because frankly why should we share knowledge that we've spent years and ££££'s acquiring with someone who doesn't feel that they need to learn and will just set up in competition - there isn't the professional courtesy or respect, small wonder we're resentful.
Alanya I expect the reason you can't get anyone to do your nails is that you are better trained and more expert than your nail tech clients and they feel defensive, suspicious and insecure. I'm actually banned from a hair salon with a self employed beauty therapist - her landlord doesn't want me speaking to her or setting foot on his premises.
