You don’t have to no. But considering you going into an industry that promotes beauty I think it is probably a good idea to.
If your to lazy to put time into your personal appearance how can you expect to have a clientele in the future that will have trust in you making them beautiful. The phrase the “mechanics car is always the last one to fix,”. Should not apply in the Beauty industry.
Oh and if your not into putting on a bunch of makeup do very minimal. Like powder, nudelips, and mascara go a long way.
