About Hair Loss
Hair grows from the hair follicular units or grafts that reside in the dermis of the scalp consisting of a group of 1-5 hair strands, which applies as the root of the hair that holds the hair by its bulb and once detached from the hair follicles, the hair is dead but the follicles grow new hair in its place.
Hair loss is a part of the hair growth cycle wherein hair grows to a certain point of time and length and afterwards it falls off then the hair follicles rest for a period and eventually a new hair grows in its place to meet the same fate. This cycle of hair transplant (http://www.hairtransplantclinic.org.uk/
Problem occurs when this cycle of hair growth is disturbed. Hair loss is clinically regarded as Alopecia, and the most common cause of hair loss/ alopecia is Androgenic Alopecia.
Androgenic Alopecia (AGA) is a genetically inherited androgenic imbalance when an enzyme called DDH is formed from the androgen hormones testosterone through the 5alpha reeducates into the dermis of the scalp causing hair follicles to dormancy.
AGA is more common in men, to occur at any stage of a man’s life usually starting from the mid 20s or 30s or even at adolescence and growing to an advanced stage by their 40s or 50s or more. It starts with hair loss and eventually occurs with hair miniaturization to a receding hairline to the emergence of the scalp to baldness.
This activity occurs typically in a pattern either starting from the temples of the head or the center of the head in men and in women it is rather uncommon if not rare, the pattern is rather diffusive that is hair loss from all over the scalp. Because of this pattern Androgenic Alopecia is often referred as male pattern hair loss or baldness and female pattern hair loss or baldness.
However, though androgenic alopecia does also affect women, but usually it’s a number of non-androgenic causes of hair loss that are more common in women like menopause, pregnancy, birth control pills, breast cancer and chemotherapy. Excluding chemotherapy, other symptoms are more temporary than permanent and once after a period of time the acute hair loss might stop, however the lost hair might not grow back.
