Hair growth supplements contain nutrients including vitamins and proteins that help to promote the growth of healthy hair in a person. These ingredients help to strengthen the growth of existing hair, however, and may not necessarily help hair to grow once again – particularly in people that experience hair loss due to a disease of the scalp or body.
The fact is, the amount of hair a person has, and the way that it grows, is genetically determined and no supplement can change the genetic properties of the hair a person has been born with. Supplements and growth pills can only maximize the health of a person’s existing hair but reputable products have been proved scientifically to help improve the health of thinning hair. People suffering hair loss should also determine the underlying reasons (for example due to stress, hormonal or vitamin deficiencies) that this is occurring before using any treatment.
