Minoxidil application? What are the signs that the treatment is working?

Not necessarily. It means it takes up to 6 months to see results with Minoxidil use. I suggest seeing a hair loss expert 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 that work well with Minoxidil. See an expert. Best, Dr. Emer

Make
sure you are applying minoxidil to the scalp not the hair shafts.  Growth related to minoxidil will be gradual
over months of twice daily application.   If unsure whether minoxidil is working after
6 months, see a hair transplant specialist for a microscopic evaluation which
will to tell you more about the quality and quantity of your hair.  Evaluating before you start minoxidil and
after 6 months of use would be the ideal times to compare results.

yes, If there are a lot of thin fine hairs growing will these get thicker with in 3-4 months by using minox twice a day .
