Common Causes of Hair Loss
The most common period of hair loss happens approximately three months AFTER delivery. The rise in hormones during pregnancy keeps you from losing your hair. After delivery, the hormones return to normal levels, which allows the hair to fall out and return to the normal cycle. The normal hair loss that was delayed during pregnancy may fall out all at once.
An immune reaction attacks the hair at the root (or follicle). Anti-bodies attack hair tissue as if they were foreign invaders.
The body’s immune system is sensitized to increased levels of DHT in the scalp causing hair loss in these high concentrated DHT areas. (DHT, or Dihydrotestosterone, causes 95% of all hair loss)
Due to pregnancy, birth control pills, menopause and/or illnesses
Too much vitamin A can cause hair loss. Medicines – some prescription and over the counter meds can foster side effects such as hair loss (see below). Usually, when the medication is discontinued, the hair re-grows.
Impetigo and Tinea Capitis.
Causes scarring of skin, loss of circulation to hair follicles and an autoimmune reaction leading to temporary or permanent loss of hair.
Lupus, Rheumatoid arthritis, Scleroderma, MCTD.
Common toxic chemicals, such as tobacco smoke, contains hundreds of lethal and damaging chemicals which can accelerate normal hair loss. This can be caused directly from smoking or indirectly from second hand smoke.
Irradiation therapy or exposure to radiation from any source can cause localized or total hair loss, sometimes permanently.
Very common with women but also can affect men.
Either hypothyroid or hyperthyroid disease causes hair to become brittle and break resulting in localized or generalized loss. Correction of the thyroid condition usually causes hair to re-grow.
Alopecia can be a reaction to foreign elements in your environment, similar to an allergic reaction
