This is not dermarolling exactly, but there are lots of people on youtube that claim to have got results from massaging scalp daily with a brush for months. Im currently 3 weeks in and I thought I will give it at least 4 months. I dont believe in miracles, but at least I can say i tried it. This will help you get rid of the fibrosis/calcification. What I have noticed is that my dandruff is more or less gone, i think its combonation of massaging scalp daily + cold showers.
