I'm a male of 24 years old. I had perfect hair no hairfall or recession issues and one day I used minoxidil as someone told me it would make hair nice and thick. After using around 3 months I noticed immense shedding of hair and I stopped it instantly and my hair density reduced and it's been more than 6 months and my hair isn't back to its usual density. Minoxidil ruined my perfect hair density. What should I do.
