Cause of Hair Loss
Kidshealth has written cause of hair loss and writes "Here are some of the things that can cause hair loss in teens: Illnesses or medical conditions. Endocrine (hormonal) conditions, such as uncontrolled diabetes or thyroid disease, 
can interfere with hair production and cause hair loss. People with kidney and liver diseases and lupus can also lose hair. The hormone imbalance that occurs in polycystic ovary syndrome can cause hair loss in teen girls as well as adult women."
Afraidtoask has written cause of hair loss and writes "The most common cause of hair loss is known as androgenetic alopecia, or male pattern baldness (in men), and female pattern baldness (in woman). Male pattern baldness is something that 7 - 15% of American males experience by age 25, and almost 40% by age 35. It is a natural, age-related change in the body, and represents over 95% of all hair loss in men."
Flash-med has written cause of hair loss and writes "The cause of hair loss, is most commonly related to male gender, hormonal changes, and genetics. However, there are some medical causes of hair loss, which include alopecia areata, arterial insufficiency, skin burns, cutaneous T-cell lymphoma, cellulitis of the scalp, dermatitis, fungal infection, Hodgkin's disease, chemotherapy effects, hypopituitarism, hypothyroidism, lichen planus, lupus, thyrotoxicosis, syphilis, seborrheic dermatitis, sarcoidosis, malnutrition, and scleroderma."
Hairlosshelp has written cause of hair loss and writes"This is the most common cause of thinning and affects both men and women. Men generally have hair loss concentrated in a specific pattern from the front through to the crown. Women tend to have thinning throughout their head without being in any specific pattern. This type of hair loss is caused by the androgen DHT, or Dihydrotestosterone. Since everyone has DHT that is produced by their bodies and only some people suffer from hair loss there has to be another factor involved. This other factor is having follicles that have a greater number of Androgen receptors for the DHT to attach to. This is the component that is inherited through the genes. To date the most effective preventative treatments are anti androgens, drugs that prevent the creation of DHT. In the future gene therapy will one day be able to alter the genes to prevent the follicles from being affected by DHT."
Drgreene has written cause of hair loss and writes "Telogen effluvium, the other common cause of hair loss in children, affects children and adults. It is responsible for more hair loss than any other cause except male-pattern baldness. To understand telogen effluvium, one must understand a hair's normal life-cycle. An individual hair follicle has a long growth phase, producing steadily growing hair for 2 to 6 years (on average 3 years). This is followed by a brief transitional phase (about 3 weeks) when the hair follicle degenerates. This in turn is followed by a resting phase (about 3 months) when the hair follicle lies dormant. This last phase is called the telogen phase. Following the telogen phase, the growth phase begins again -- new hairs grow and push out the old hair shafts. The whole cycle repeats. For most people, 80% to 90% of the follicles are in the growth phase, 5% are in the brief transition phase, and 10% to 15% are in the telogen phase. Each day about 100 hairs are shed and replaced by new hairs. In telogen effluvium, something happens to interrupt this normal life-cycle and to throw many or all of the hairs into the telogen phase. Between 6 and 16 weeks later, partial or complete baldness appears."
