If you are still in school, you may want to contact the Applied Technology Center of Rock Hill District 3 Schools. They have a cosmetology program which includes nail tech and can provide a SC Board of Cosmetology license when the program is successfully completed.
Even if you are not a student or do not want to pursue a vocation as broad as Cosmetology, you may still be able to get some answers to your questions by contacting the school!
