No I think physics chemistry and mathematics  is needed to opt for cosmetology. The basic qualification to get admission in cosmetology are 10+2 with physics, chemistry and mathematics as the main subjects. The age limit should be 17 years and above.

The other way to get here through pcb is...

If you have passed 12th standard and want to enter cosmetology sector, you may go for general cosmetology courses. If you are interested in clinical cosmetology, you will have to complete MBBS first. After that, you may go for relevant PG Diploma course related to clinical cosmetology.

Best wishes buddy. Thank you.

Hello Anjali,
To become a cosmologist, its compulsory to have PCM in 12th and after that as eligibility you must have a degree of physics or maths hons.
As you told, you are PCB student, so you aren't eligible for cosmologist.
You can choose other options.
Good luck
