Massage
A study conducted in Japan showed that scalp massage could increase hair thickness. The men involved in the study had regular massages over a 24-week period, and while hair growth rate did not improve, thickness improved significantly.
Researchers believe that this could be to do with increased blood flow and direct stimulation of the cells.
Nutrition
While hair loss can be affected by nutrient deficiency, the exact links between diet and hair loss are complicated:
Iron: Iron deficiency is the most common nutritional deficiency in the world and is a known cause of hair loss. Women experiencing perimenopause and menopause are at risk of iron deficiency, as are vegans, vegetarians, and people with certain conditions, such as celiac disease. In a study on mice, the reversal of iron deficiency also leads to the restoration of hair growth.
Zinc: Zinc deficiency has a direct link with brittle hair, and increasing zinc levels also leads to the regrowth of hair. However, researchers do not know whether zinc supplementation would help those without diagnosed zinc deficiency.
Fatty acids: A deficiency in essential fatty acids can lead to hair loss on the scalp and eyebrows.
It is important to remember that there is a lack of research on the role of supplementation. Researchers do not know whether supplements will prevent hair loss in people that do not have nutrient deficiencies.
In fact, the over supplementation of certain nutrients, such as vitamin A, vitamin E, and selenium, can lead to hair loss.
Stress
There appears to be a direct link between stress and hair loss. Likewise, a shock to the system, be that through physical or emotional trauma, can also act as a shock to the hair follicles and they can stop growing.
