The Truth About Hair Loss
It is normal to shed hair every single day and also the truth is we loose between 100-125 hairs on a day. Hair that is shed falls out at the conclusion of growth cycle. At any time 10% of our hair is in what is called a “resting phase” and after 2-3 months resting, hair falls out and new hair grows in its place. Many people, however, experience more hair thinning than is normal.
Once we grow older, both men and women experience some hair thinning. It’s a normal the main aging process. Called Androgenetic Alopecia, it makes up about 95% of all hair loss. Androgentic Alopecia often runs in families and affects many people a lot more than others. In men it is often referred to as Male Pattern Baldness.
It’s characterized by a receding hair line and baldness on the top of head. Women, however, don’t go entirely bald even when their hair loss is severe. Instead, hair loss is spread out evenly over their entire scalp.
Hormones play the dominant role when talking about Androgenetic Alopecia. Simple put, both women and men produce testosterone. Testosterone can be transformed into dihydrotestosterone (DHT) with the aid of the enzyme 5-alpha-reductase. DHT shrinks follicles of hair causing the membranes in the scalp to thicken, become inelastic and restrict blood flow. This causes the head of hair follicles to atrophy. Consequently, whenever a hair does fall out, it’s not replaced.
Needless to say, men produce more testosterone than ladies and experience more hair loss.
While Androgenic-alopecia may be the biggest reason why individuals experience hair thinning, it is not alone. Health conditions such as hypothyroidism, ringworm and fungal infections may cause hair thinning. Certain medications for example blood thinners, gout medication, birth control pills and an excessive amount of vit a can cause sudden or abnormal hair loss just like following a crash diet, sudden hormonal changes, chemotherapy and radiation.
Emotional stress, pregnancy, or surgery may also cause our hair to fall out and it is not often noticed until 3-4 months after the stressful event has taken place. Stress may cause a slowing of new hair regrowth just because a larger number of hair follicles enter into the resting phase with no new hair regrowth has experience.
One other way by which individuals experience hair thinning is due to mechanical stressors about the remaining hair head. Wearing pigtails, cornrows or tight rollers that wind up pulling about the hair can scar the scalp and cause permanent hair thinning. Hair products for example hot oil treatments and chemicals employed for permanents can cause inflammation to the hair follicles which can also result in scarring and hair loss.
