Causes of Hair Loss
DHT, or Dihydrotestoterone, is a hormone created when the enzyme 5-alpha reductase interacts with the male hormone
testosterone in a man's body. This chemical reaction results in excess levels of DHT, the chief culprit in male hair
loss and prostate problems.
Too much DHT present in the scalp causes androgenetic alopecia, otherwise known as male pattern baldness.
When DHT binds to androgen receptors on hair follicles, the corresponding hair in the hair follicle shrunks
and becomes less visible. Because only men have high levels of testosterone that can be chemically altered
to form DHT, hair loss is much more common in men than it is in women. Men can begin early stages of androgenetic
alopecia as early as in their twenties.
Research has shown that the most effective method for hair growth is to first STOP the root cause of hair loss. Let the body regrow the hair naturally or use another agent to help regrow the hair. Leading DHT blockers in the industry such as maxahair, Shen Min Nioxin, Nu-Hair, have shown to be effective in stopping the hair loss process.

Decreased Blood Flow Causes Hair Loss
Another reason why hair loss happens is poor blood circulation to the root of hairs. The synthesis of hair requires a lot
of nutrients. Blood is the provider of required nutrients. If the roots of your hair do not have an ample supply of blood,
hair follicles sop producing hair.
Loss of circulation can occur for many reasons. Old age causes deterioration in vascular tissue, tense muscles in the
neck and forehead can constrict capillaries and prevent sufficient blood flow, stress can work with DHT to tighten the scalp.
What is the normal cycle of hair growth and loss?
The normal cycle of hair growth lasts for 2 to 3 years. Each hair grows approximately 1 centimeter per month
during this phase. About 90 percent of the hair on your scalp is growing at any one time. About 10 percent of the
hair on your scalp, at any one time, is in a resting phase. After 3 to 4 months, the resting hair falls out and new
hair starts to grow in its place.
It is normal to shed some hair each day as part of this cycle. However, some people may experience excessive (more than normal) hair loss. Hair loss of this type can affect men, women and children.
What causes excessive hair loss?
A number of things can cause excessive hair loss. For example, about 3 or 4 months after an illness or a major surgery,
you may suddenly lose a large amount of hair. This hair loss is related to the stress of the illness and is temporary.
Hormonal problems may cause hair loss. If your thyroid gland is overactive or underactive, your hair may fall out. This hair
loss usually can be helped by treatment thyroid disease. Hair loss may occur if male or female hormones, known as androgens
and estrogens, are out of balance. Correcting the hormone imbalance may stop your hair loss.
Many women notice hair loss about 3 months after they've had a baby. This loss is also related to hormones. During pregnancy,
high levels of certain hormones cause the body to keep hair that would normally fall out. When the hormones return to pre-pregnancy
levels, that hair falls out and the normal cycle of growth and loss starts again.
Some medicines can cause hair loss. This type of hair loss improves when you stop taking the medicine. Medicines that can
cause hair loss include blood thinners (also called anticoagulants), medicines used for gout, high blood pressure or heart
problems, vitamin A (if too much is taken), birth control pills and antidepressants.
Popular treatment for hairloss include:
DHT blockers such as: Procerin, Maxahair, Nioxin, Provillus, revivogen, Nu-Hair, Shin Min (Shen Min).
Finasteride (Propecia) is a prescription hair loss treatment that is prescribed for men only.
Minoxidil (Rogaine) is rubbed directly onto the scalp and works for both men and women.
Various hair loss shampoo (folicure, nizoral, nixoin, progaine,etc, etc.)
