I am 21 years old. I was gradually losing the hair quantity and thickness on the vertex for the last 3 years.I consulted a doctor and did 6 prp sessions and used minoxidil,biotin and
vitamin.But I got no benefit from prp and minoxidil. So what can I do now? Is there any other treatment I shoulder try?Now I've decided to use dermaroller along with minoxidil.when should I use minoxidil?Immediately after dermarolling or 24 hours after dermarolling?My dermaroller is 1mm.How often should I use it?
