I’m assuming the young ones who start at 16 are required to go to college so they most likely are if they start with her straight after leaving school but I totally believe sammy jo isn’t qualified to teach I know how much effort it is to get a qualification to teach eyelash extensions from one of my friends she actually had to do a course for months on an evening after work to be an accredited trainer so id imagine it would be the same with hair / probably more strict as its more regulated then lashes / beauty.
