You need to see an expert doctor like me, who can do a HAIR CHECK test (https://baldingblog.com/haircheck-test-how-it-is-done-video/) on you to determine if you are going to go bald. This is a lot of recession in someone 20 years of age. Who do you take after in your family line? Blondes are the BEST candidates for hair transplants, but at your age, I would be hesitant to recommend it. You should absolutely be on the drug finasteride if you want to keep your hair. I find that blondes are the best hair transplant candidates because of the low contrast between hair and skin color. If hair is important to you, you will look at my comments seriously.
