Taking finasteride 1mg from last 7 months but still losing hair, what should I do?

A:  In clinical trials, 90% of men respond to finasteride but there is a small percentage that does not. However it does take time and often, we recommend committing to finasteride for a 1-2 years before determining how effective it is for you.  Adding treatments to your routine such as PRP, laser therapy, or minoxidil may help as well.  In fact, there was a study that proved the combination of minoxidil and finasteride work better together than either one alone. (Dermatol Ther. 2015 Sep-Oct;28(5):303-8.Combined treatment with oral finasteride and topical minoxidil in male androgenetic alopecia: a randomized and comparative study in Chinese patients.)
Consulting with a board certified dermatologist is important to determine the nature of your hair loss before stopping or starting any medication.
 
 

I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. 

Finesteride will not always cause hair regrowth; but almost always usually decreases further hair loss.

You didn't include much information about yourself or a photo.  The best way to proceed would  be to see a board certified dermatologist who specializes in hair loss.   They could evaluate your condition and make recommendations for you,  PRP treatments offer improvement for all types of hair loss.   Sometimes blood tests and or a biopsy of the scalp is needed.  

Finasteride doesn't always work and when this happens, you need to sit down with your doctor and review the Master Plan you have created with him for your short and long term hair loss
