Many people regard people that have healthy-looking or abundant hair as being desirable or beautiful. Because of this when people begin losing their hair (as they age, for example) they look for medications or therapies that will prevent this.
Like all parts of the body, hair requires a variety of nutrients to grow and be healthy and often hair loss occurs as a result of nutritional deficiencies in a person’s diet. Hair loss can also be affected by genetic predisposition, aging and hormones.
While hair growth supplements are marketed as the solution for achieving healthy hair, there is no scientific evidence that supports some of the claims made for them. What is known is that certain key nutrients can help promote healthy hair growth including protein, iron, zinc and vitamins A, B12, C, D and E. Protein is particularly important as it is the main component of hair.
