Mid 40’s diffuse thinning. Not bad. Gave Rogaine a try and within weeks was much thinner. It says doesn’t work at the hairline, but the hairline went from fairly full to very thin. If it doesn’t work at the hairline why would it shed hairs there? If it shed hairs at the hairline does that mean it will grow them back? Otherwise why continue to use it?
Your experience is unusual. Shedding reports with Rogaine do not explain your findings. I don’t have all the answers, and this is certainly such a case. There is a suggestion that for some users, Rogaine accelerates the anagen stage in the hair loss cycle, which means that it first has to go through telogen (hair loss phase). I would think it would regrow there, but I can’t confirm with any sort of guarantee.
Remember, hair grows at a rate of 1/2 inch per month, so in a month all the benefit you can get will impact only the lowest 1/2 inch of hair. This usually gets better in a couple of months, so do not get discouraged. Speak with your doctor and ask him/her to measure your hair bulk to get a baseline measurement to compare to after 3 months.
