Dear Keshav,
Cosmetology is related to the study of cosmetics and their use. The course covers basic and advanced areas in Skin Care, hair care, electrolysis, weight management, make-up, Laser course, spa course, aroma therapy, salon services, nail course, mehendi course, salon management skills, etc.
Since you have asked the question months ago, I hope you have got admission in any decent college.
Also, selecting any course depends on individual's personal skills and interests. You should opt for the course in which you are interested.
Good Luck!
