Hair shedding after 7 months use of minoxidil 5?

 I recommend getting a formal evaluation with a hair loss expert to go over your condition and advise you on best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Minoxidil may not be efficient any more to stop heavy genetic hair loss and you may need an another supportive treatment to combat with hair loss. 

You'll want to see a physician about this as there could be so many causes. It may or may not be related to minoxidil.
