Brush your hair!! :)
When I brush my hair... well, scalp rather... every day until it's sore, it stimulates hair growth!
I've had fairly bad MPB for years now, and this is the FIRST thing that has worked for me :)
Now, it's not perfect, and I use antifungals on my hair nightly as well to control the dandruff (such as thyme, tea tree or grapefruit seed extract in water) but it does really help and gives regrowth!
I brush my scalp all over for about 30 minutes a day, but that might be overkill. Two 10 minute sessions a day seems optimal, as long as your scalp is red/hurting a bit by the end.
I use a fairly hard boar bristle brush.
Hope that helps someone :)
