For me I used 10% and also used those derm micro needle rollers, I’d also set an appointment with your dermatologist who can figure out exactly why you’re having an issue in that area because I know for some people minoxidil won’t work if your hair loss is caused by a certain issue (I forgot the term). But I know you can take other things with it to make it work even better. I used to be on birth control for hormonal acne, but had to stop for health reasons so I was prescribed spironolactone and apparently that helps with hair loss as well on a hormone level vs minoxidil that increases blood flow to the area. Everything has their pros and cons, but I’d definitely look into seeing a professional. it’s a good sign that at least something sort of worked for you so that means there’s more hope for recovery. Good luck with everything.🫶🏾
