The scientists have revealed the truth regarding inherited hair loss
During this genome conference that took place in Africa, the scientists have demonstrated that some forms of hair loss occur because of genes. Androgenetic alopecia is, accordingly to http://ghr.nlm.nih.gov/condition/androgenetic-alopecia, a frequent type of hair loss that affects both men and women.
The AR gene is related to androgenetic alopecia. Despite the fact that alopecia is a common cause of hair loss in women and men, it is more often in men. The risk of being affected by hair loss increases with age, while the lifestyle, stress and nutrition could have an impact as well.
But the scientists sustained at the genetics conference that most of the factors that lead to hair loss are unknown. Androgenetic alopecia is also associated with the levels of the hormones known as androgens, especially with dihydrotestosterone or DHT.
Provillus has been designed to support men and women affected by androgenetic alopecia. Having a powerful formula with natural ingredients that prevent, slow and stop the process of hair loss, Provillus from www.Provillus.org improves the appearance of scalp and nourishes the follicles so the hair will grow healthy.
Androgens are crucial for the normal development of the reproductive system in men before birth and in the course of puberty. But this chemical also normalizes the libido and the development of hair.
The development of hair starts in the follicles found beneath the skin. Normally, every strand of hair grows for two – six years, enters in a resting stage that lasts a few months then falls of the scalp. The cycle starts over when new hair starts developing. But high levels of androgens in the follicles reduce the lifespan of follicles, while the hairs will grow thinner and finer. Even more, the resting stage will last longer and it will take more time to grow again new hair.
Researchers have shown at the Africa genome conference that variations in AR gene have been found in men and women affected by hair loss. This gene offers directions for producing a protein known as androgen receptor. Androgen receptors enable the organism to respond properly to DHT and other androgens. But the variations in AR gene trigger an enhanced activity of the receptors in hair follicles.
It is not clear how androgenetic alopecia is inherited, because there are involved numerous environmental and genetic factors. Having a close family member with baldness can be considered a risk factor for developing androgenetic alopecia.
In addition, researchers have stated that it is not quite known how the prostate cancer, polycystic ovary syndrome or coronary heart disease are linked to increased levels of androgens, but people with these conditions are likely to lose their hair.
Alopecia or hair loss does not appear only due to genes, but aging, stress, medications, drugs, nutrition and lifestyle also play important roles. It is important to lead a healthy and active life in order to maintain the general health and a beautiful appearance of scalp. Hair loss can be prevented with proper care and a balanced lifestyle.
