Is it possible to go from Norwood 2 to Norwood 1 using Dutasteride and Minoxidil?

I recommend a consultation with a hair loss expert to go over your condition and options. PRP and progesterone injections are also good options and/or hair transplantation. See an expert. Best, Dr. Emer

Given your age of 21, in part your hairline is changing form a juvenile to a more mature hairline.  However, having started on minoxidil and dutasteride as preventative medications will help you keep what you have.  You might want to change from dutasteride to finasteride as it has less side effects.  Also, you should see a hair transplant specialist for a baseline evaluation.

Preventative medications do not regrow your hairline, they prevent further loss. It is best for you to have a consultation with a hair restoration expert to assess your non-surgical as well as surgical options. Also, dutasteride has a higher side effect profile than finasteride.

It is unlikely the medications listed will help in your hair line. It may be part of a normal maturation of your hair line from an adolescent hair line to that of an adult male. Providing pictures may be more helpful.

Usually medical hair regiment slows down the progression of hair loss, but there is not significant amount of hair growth specially in the hair line area. If you are concerned about the hair line, it is best to get a consultation to get hair transplant for hair line.
