There are nutrients and herbs that have the potential to affect hair growth in a positive or negative way.
There are three basic ways that nutritional diet vitamin supplements and amino acid supplements may act influence the hair follicles. The mineral rich and vitamin supplements may act directly on hair stimulating or inhibiting growth activity or they may act indirectly through other intermediaries. For example, a vitamin supplement or herb may influence the production of a hormone to which hair follicles are sensitive. This change in hormone activity in turn may change the activity of the hair follicles.
Some minerals and vitamins can influence the activity levels of another vitamin and minerals. For example, intake of lysine, vitamin B12 and vitamin C help in absorption of other factors like iron. It is worth bearing in mind that the complexity of the body means there are many potential interactions for even the simplest nutrient.
Vitamins for hair & hair growth
Since Vitamin C, helps the absorption of other factors, it is of some significance. Others are of secondary importance to hair growth like vitamin E. Vitamin E is necessary to provide good blood circulation to the scalp by increasing the uptake of oxygen. Not fundamentally required in a hair growth supplement, vitamin E is often present largely because people expect to see it in the ingredients - and the customer is always right!
Other common ingredients like the amino acids - L-Cysteine and L-Methioine are of questionable value. Although they are fundamentally required for good hair growth, even a rather unhealthy diet should provide enough of these amino acids and supplementation is rarely required.
Vitamin supplements are marketed by different names such as liquid vitamin supplements, natural vitamin supplements, daily vitamin supplements, nutritional vitamin supplements and by such names as mail order vitamin supplements or best vitamins supplements.
The deficiency which directly affects hair growth can be related to vitamin (H) biotin, Vitamin B6 and Vitamin B12. You can go for testing for others if they are on offer, but biotin and B6 testing is enough to cover 95% of vitamin deficiencies related to hair loss.
