Alopecia, medically defined as hair loss of any kind, has many causes and affects millions of people each year. While some hair loss is permanent, some shampoos formulated with herbs and supplements produce positive regrowth results.
Why Hair Loss Happens
Dihydrotestosterone, a hormone metabolite commonly known as DHT, is responsible for many cases of hair loss in men and women. DHT causes follicles to shrink and releases a waxy substance at hair roots that blocks proteins and other nutrients from reaching the hair follicles. That, in turn, prevents hair from growing. Some natural shampoos are formulated with ingredients to reverse or prevent the effects of DHT.
Ingredients
According to WebMD, one of the essential nutrients for healthy hair, skin and nails is biotin a member of the B complex family of vitamins. Green tea promotes increased levels of the sex hormone binding globulin in women. SHBG helps to decrease levels of hormones responsible for hair loss. Silica rich herbs like horsetail and nettle also promote hair growth.
Shampoos
DS Labs touts its High Performance Hair Growth Stimulating Shampoo as anti-inflamatory and rich in antioxidants and amino acids that help reverse the effects of DHT. Mill Creek Biotin Shampoo contains panthenol, niacin, inositol and folic acid. Aubrey Organics Green Tea Shampoo combines green tea with other herbs, such as silica-rich nettle.
Other factors
Although topical solutions have some effectiveness in promoting hair growth and regrowth, nourishing the follicle from the root through proper diet and supplements is also important. For best results, create a hair care regimen that includes a healthy diet while limiting the use of harsh products and high heat---via dryers---that may harm the hair.
