Hair-D-Boost uses ReJuviance transdermal technology to deliver modest amounts of Vitamin D across the scalp directly to the hair follicles where it is needed, avoiding the risk of excessive Vitamin D. Hair-D-Boost also contains an herbal anti-inflammatory intended to block the recently discovered hair growth inhibiting prostaglandin compounds, and contains 2% concentration of herbal hair growth stimulant beta-Sitosterol.

So far so good, but the price compared to the quantity is rather low. I recommend supplying a higher quantity at same or almost the same price.

Recent international research has discovered that stem cells are encouraged to become hair follicles that produce hair on our heads and body. The Vitamin D receptor is crucial to that stem cell alteration. In July 2012 Japanese researchers demonstrated in animals that adding Vitamin D helped the process of using stem cells to generate new follicles. [The Search for a Baldness Cure, Wang, Shirley S., The Wall Street Journal, September 12, 2012] Hair follicles typically produce hair for 2 to 6 years before the hair falls out and the follicle lies dormant for a few weeks-to-months. With healthy follicles a replacement hair then emerges. In some men the sleeping phase becomes permanent and the stem cells on these men lose the ability to differentiate into new hair follicles, becoming skin cells instead, resulting in baldness. Some researchers are looking for chemical molecules that could be preventing the cellular receptor for Vitamin D from performing properly. Others have found that a compound Prostaglanden D2 (PGD2) is present at elevated levels in the scalp of bald men and suspect that if that compound could be blocked normal follicle cell function might return to produce hair properly. [A War on Baldness, Fought in the Follicle. Eisenberg, Anne, The New York Times, July 28, 2012] Taking too much Vitamin D by oral supplements can have negative side effects on body calcium levels and lead to kidney problems, so it is important that any Vitamin D used to stimulate the body be finely targeted, in this case to the area of balding skin.
