Over 90 percent of hair loss is attributed to androgenetic alopecia, which is a hereditary or genetic factor that contributes to such a hair loss. This has often been referred to as pattern baldness, both male and female. Although within the female sense of the pattern baldness, this is represented by a somewhat receding hair line and a general thinning of the hair across the entire head, whereas the male pattern baldness affects both receding hairline as well as the top of the head normally shown as the bald spot.

According to research and medical reports, the role of hormones is significant in androgenetic alopecia, which is linked to the production of dihydrodotestosterone, which results in the shrinking of hair follicles, as well as the thickening of the scalp membranes. Essentially the short version is that once the hair falls out, a new one will not grow in its place. Based on the fact that men produce more testosterone than women, the result is the fact that men lose more hair than women.
In addition to the above mentioned issues such as stress, taking certain medications or undergoing specific medical treatments, and fungal or ringworm infections can contribute significantly to hair loss. Specifically identified medical treatments include chemotherapy, radiation treatment, crash diets and sudden hormonal changes, whilst the intake of gout medicine, blood thinners, too much Vitamin A and birth control medicines have also been linked to the loss of hair.
As far as stress goes, claims have been made that it does indeed contribute to hair loss, however in the event of a major stressful event the effects are only realized after a couple of months, which ties into the above mentioned 'resting phase' as described. However in this instance, due to the 'shock' to the system the new hair does not follow the falling out of the rested hair. Hair products have also been known to contribute to hair loss, especially the harsher chemical type products that 'burn' the hair, as well as the style of which you might wear your hair in. Tight pony tails, or excessively pulled back hair can become damaged, which in turn can result in hair loss.
Many products exist and are available that promise to help stop hair loss, what you have to bear in mind is that not all products work for all people, so you would be best advised to either check the reviews of the products or try each product, until you find one that works for you.
