The hair loss problems affecting most men, approximately 80% of the male population, women, and even 50% of women. Androgenetic alopecia is considered the cause of most cases of hair loss. This type of hair loss is due to genetics of a person, stating that there are more people who are genetically predisposed to hair loss. There is a theory, however, that uses the explanation of skull expansion as the main cause of genetic hair loss.
Still there is no doubt that androgens cause hair loss in individuals who are genetically predisposed to it. Dihidrotestosterona or DHT, specifically, the hormone is directly related to hair loss. However, on the theory of hair loss due to the expansion of the skull, genetic predisposition and the presence of male hormones are not fully explain the mechanism behind the hair loss. Some pertinent questions about the process of hair loss can be answered using the skull expansion explanation. These issues include the reasons why people lose their hair at the front and rear parts of the scalp, why hair falls faster in an area of the scalp in comparison with others, and how it relates to the DHT hair loss and growth.
Before discussing the theory of hair loss due to the expansion of the skull as a viable explanation for hair loss, it is best to respond to the above questions completely and accurately. Based on the skull idea of expansion to explain hair loss, when people grow in the adult skeleton gets bigger including the skull, which grows in size and at the same time, changes in shape. Upon reaching adulthood, the process known as remodeling and bone resorption continues. For some people, this is simply that the maintenance of bones รข € "maintaining healthy bones, but for some, leading to the growth of the frontal and parietal bone of the skull. This growth is known as the expansion of the skull and is said to be the direct cause of hair loss in these areas of the scalp.
The genetic factor involved in male pattern baldness is probably due to the shape of the skull that has which was also attributed to genetics. Different forms of skulls have different potential for growth. The degree of hair loss is related to the degree of expansion of the skull, which means an enormous change in the skull shape more can cause hair loss.
When used to respond to the questions above, the skull caused by the expansion loss of hair on the front and side areas of the scalp. As the frontal bone grows, the hair is also lost in that area. The same theory applies to hair loss in the parietal bone. The varying rates of hair loss in different areas of the scalp will depend on the shape of the skull and how it grows over time. The relationship of DHT to hair loss is known, and agree with the idea of hair loss attributed to the expansion of the skull, DHT not only stimulate hair growth, but also increases bone growth. The androgens are regarded as steroid hormones that give effect anabolizante in the formation of bones. DHT causes the skull to expand what has caused hair loss.
