Hair loss and possible treatment.
Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body.
Hair follicles undergo three stages of the hair growth cycle called anagen, catagen, and telogen, which corresponds to the growing, regressing, and resting phases, respectively.
People have between 100,000 and 150,000 hairs on their head. The number of strands normally lost in a day varies but on average is 100.
In order to maintain a normal volume, hair must be replaced at the same rate at which it is lost. The first signs of hair thinning that people will often notice are more hairs than usual left in the hairbrush after brushing or in the basin after shampooing.
Hair thinning and baldness cause psychological stress due to their effect on appearance.
The psychology of hair thinning is a complex issue for both sexes and can have an impact on an individuals overall identity. For women, it often represents femininity, fertility and attractiveness.
Men typically associate a full head of hair with youth and vigor. Although they may be aware of pattern baldness in their family, many are uncomfortable talking about the issue. Hair thinning is therefore a sensitive issue for both sexes.
Dermal papilla cells (DPCs) play a key role in hair growth among the various cell types in hair follicles. It has been investigated the hair growth promoting effects of He Shou Wu extract in cultured human DPCs and the underlying molecular and cellular mechanisms. It was found that treatment of He Shou Wu extract stimulated proliferation and mitochondrial activity in cultured human DPCs.
In conclusion, studies strongly suggest that He Shou Wu extract could support hair growth by extending anagen duration and delaying catagen progression and could possibly prevent hair loss by abrogating the effects of androgen which result in hair follicle dermal papilla miniaturization, suspected to be a main cause of androgenic alopecia (AGA) or hair shaft weakening.
