Western hair loss combat tip is to direct more blood flow to the scalp, thus we have medicines like Minoxidil, Regaine, which are believed to dilate the blood vessels in our head so as to direct more blood to our scalp, nourishing our scalp follicles. Certain hair loss therapies may involve the use of laser beams to direct more blood flow to the scalp.
Eastern anti hair loss tips exhort an 'inner-outer' approach, inner approach relies on traditional chinese medicine to strengthen the kidneys which is related to hair health and outer approach is via hair treatments using Chinese herbs to strengthen the hair roots.
A natural approach is to clean the scalp thoroughly, rid it of all the oil and dirt which inhibit normal hair growth.
This is what I have summarised from my research on hair loss. If you have any other methods you read about, please post a comment. Thanks!
