Hair and acne problem. 100 mg tablets.

I have very less hair on the front part of my head for almost 9-10 years. Also for the last 6 months i have been suffering from an acute acne problem, in spite of not having an oily skin texture earlier. I have tried Benzoyl peroxide gel 5% and Clindamycin 1% gel. But both haven't worked. Recently i visited a doctor. She suggested me Morr 3% . Is morr 3% safe for women to use? Also is it for frontal thinning of hair. I want new hair growth. For skin in spite of me having told her clearly Clindamycin didn't work for me, she prescribed me that very medicine. She also gave me T.doxycycline 100 mg tablets. However she didn't give any medicine for the lightening  of the acne scars. Are the medicines safe to use. Please help me with it.
