I visited a dermatologist for my hair loss problem. He prescribed me Keraglo Eva tablets and Keragris revitalizing hair serum for 4 months. Now I have a doubt: after 4 months, will I face hair loss again? Will my hair continue to grow, or will the hair loss start again after completing the 4-month course? I’ve found a lot of information on Google, but I’m not sure which one is correct.   PLEASE HELP!!!

It started 3 days ago where my right index finger became swollen and painful to touch on its side. I expected it to go away a few days later but it's been 3 days now and even though it's not as painful as it was before, it's still swollen and painful. Over the counter painkillers have worked so far but I don't want to keep using them and I wish to get this resolved as soon as possible. Could anyone suggest what do to next about my problem? I would greatly appreciate it.
