Hair loss, known scientifically as alopecia, can be the result of a wide range of causes. Cicatricial alopecia refers to hair loss that occurs after the hair follicles are damaged, either through inflammation, or by physical means. This damage is permanent and creates scar tissue within the site of hair production, preventing any hair in the future from growing. Noncicatricial hair loss, however, leaves the hair follicle undamaged, suggesting that regrowth of the hair is possible in the future.
Characteristics of Excessive Hair Loss
Hair shedding is a normal part of the growth and development cycle of hair. Usually a hair follicle goes through a period of growth, shedding, and resting. You should not feel distressed if you find some hair falling out. If you have long hair, it may seem that the quantity of hair shed may be excessive; however, excessive hair loss is the loss of 100 or more strands of hair per day. This shedding may be noticed while combing hair, washing it, or in other ways like waking up to a pillow covered in hair. If you notice this excessive shedding, you should see a dermatologist in order to diagnose and treat your condition. The treatment may involve topical or oral administration of drugs, or may be just a change in diet.

Treatments for Hair Loss

Can Stress Cause Hair Loss?
Stress has a wide range of effects on the body. Stress hormones may affect the skin, nails, and hair and change the way they function. One of these functions is the production of skin oils, which during stress increases and can aggravate conditions like dandruff. The function of hair growth itself can be altered during times of stress, resulting in hair loss.
When you are stressed, your hair production may be hindered and hair that falls out and enters the rest phase of hair growth does not grow back right away. The accumulation of hair follicles suspended in that rest phase during stress means that the hair that is naturally falling out is not replaced. The thinning that results from this is stress induced hair loss.
