Hello dear, Androgenic alopecia, also known as Male pattern baldness, is related to genetic makeup and male sex hormones. Management includes: 1. Minoxidil preparation to be applied directly to the scalp to stimulate the hair follicles. 2. Finasteride preparations (Finax) that interferes with the production of male hormone linked to baldness. So, your Doctor is correct in prescribing you the medications. But these medications have to be used regularly under the guidance of a Dermatologist...as hair loss tends to return on stoppage of these medications. You are correct regarding the fact that these medications have lots of side effects on long term usage. And since you are just 19 years old, hair transplant can be a good option for you. Kindly discuss with your treating Doctor regarding this. Wishing you a Good Health. Take care.
