Increasing blood flow to the scalp can be an effective way to reduce hair loss and restore hair. When the scalp is properly supplied with blood, it contains many of the building blocks necessary for the growth of new hair cells and keeping the scalp healthy.
Many hair growth methods, such as topical minoxidil and laser combs, originally improve hair growth by increasing blood flow to the scalp. Minoxidil dilates blood vessels, which results in increased blood in the scalp.

The laser comb stimulates "vascularization", which expands the capillaries and increases blood flow to the follicles. Poor blood flow to the scalp is probably not the main cause of baldness in most people.
There are other, more significant causes, such as a genetically inherited susceptibility to DHT, a byproduct of testosterone that causes male pattern baldness, or "androgenic alopecia".
DHT and genetics may be a more important cause of baldness than poor blood flow to the scalp. With an above-average blood supply to the scalp, it is possible to stop hair loss and stimulate hair growth by compensating for other causes with a rich blood supply.
The only way to successfully prevent hair thinning is to increase blood flow to the scalp. But it is much better to address all the main causes of hair loss, including stress, hormonal imbalances, and inadequate nutrition. Treating hair loss by eliminating the cause gives you a much greater chance of successful hair restoration.
