All of us are aware of the importance of hair for a person to look beautiful. Hair loss could be because of nutritional deficiency, hormone imbalance, stress or diseases. Its most common cause is adrogenetic alopecia. This is the medical term for hair loss or baldness. Hair loss shows genetic behavior.
Phases In The LifeCycle Of Hair
A hair typically undergoes three phases- anagen lasts for two to six years producing well pigmented-thick hair. At any point of time, roughly 90% of the scalp hair are in this growth phase. In the second phase, the hair starts becoming thinner and follicle starts shrinking. This phase is called catagen and is a transient phase lasting for few weeks.The last phase, telogen is for two to four months, where the thinned hair falls off making way for new hair.
DHT hormone- The culprit
DHT stands for dihydrotestostrone. This hormone is produced in both the sexes. It is required for proper growth in the early phase of one’s life. In men DHT is
produced in testicles and adrenals. In women, it is produced in ovaries and adrenal glands. However, as men become older this ‘hero’ turns ‘villain’. Once formed, DHT binds to the hair follicles, thereby retarding their growth and cutting of their blood supply. This is followed by period of thinning of hair and finally hair falls.
Illness and medications too could be cause of hair loss. Diseases that could lead to hair loss are thyroid , diabetes, kidney failure and lupus. In adult women and teenaged girls, the cause could be hormone imbalance in polycystic ovary syndrome.Medications such as acne medications can lead to hair loss, so can Amphetamines in diet pills. Chemotherapy is known widely to cause hair loss. A skin disease called Alopecia areata causes hair loss on the scalp and sometimes on the body. It is an autoimmune disease, which means that the own immune system is the one to damage the hair follicles.It starts as small bald patches and can progress to total baldness. In a psychological disorder called Trichotillomania a person pulls his/her own hair that can also lead to hair loss.One ought to be cautious in receiving hair treatments and styling the hair. These activities give tension to scalp thereby damaging the hair and ultimately leading to hair loss.
A product “Provillus” available in the market is designed to block DHT and supply proper nutrients to the body.
