He pressed the pads of his fingers firmly on my scalp, not the nails he stressed as that could damage the follicles, but the soft pads. He pulled them in opposite directions hard and it hurt in the areas where I was starting to get thinning hair. I did this vigourous massage for a few days and it stopped hurting and the hair got thicker again eventually. He said that was the most important thing he learned and if he did it sooner he could have kept most of his hair. I think it worked as my brother lost his hair and I kept mine so far.
Also don't wear a helmet. They can make you lose a ton of hair permanently.
Hope this helps.
