Answer:
It's all about blood flow, really! its pretty simple. all you need are fingers and your bed or a chair or something like that.
1. (rumour) it may work give it a shot, anything containing cocanut butter, such as hand cream or something along the lines is suppose to help.
2. ok yes back to the original topic, rub rub rub! whenever you have spare time, RUB YOUR HEAD, not scratch RUB! rub the bald spots to help blood build the follicles.
3. use your bed just before bed... if that makes any sense, lay yourself over the bed and make your head tilt downward so the blood can go into your head, no don't stay there for too long or else your head will probably explode be carefull don't fall off of the bed and crack your neck!!!
