To understand the main causes of hair loss, let’s first talk about healthy hair growth. Hair grows in cycles in three different phases.
Anagen Phase:First, there is the anagen, the active growth phase where the root divides rapidly and new hairs are formed. Hair grows about one centimeter every 28 days. So think about that when looking in the mirror. Can you see one twenty-eighth of a centimeter?
That is why, when your hair starts growing again thanks to our treatments, it is difficult to see at first. Scalp hair stays in this active growth anagen cycle for 3-7 years.
Catagen Phase: When a signal causes the end of the active growth of a hair, the catagen phase begins. Here the hair follicle is in a transition stage that lasts for about 2-3 weeks. It converts to what’s called a club hair. The process cuts the hair off from its blood supply and from cells that produce new hair.
Telogen Phase:When the club hair is fully formed the hair follicle rests, which is called the telogen phase. It lasts from one to four months. The club hair is a dead, fully keratinized hair. Fifty to one-hundred hairs a day in this stage are shed from a normal, healthy scalp.
So essentially, the three hair phases are growth, transition, and rest. In healthy hair, at the end of the telogen phase, the hair follicle reenters the anagen, or growing, phase.
The Major Cause of Hair Loss in Men and Women
The major cause of hair loss in both men and women is DHT (dihydrotestosterone).
DHT is the active form of the male hormone testosterone. It binds to the inside of capillaries underneath your hair follicle and blocks it from getting nutrients and vitamins.
It's like choking the roots of a tree. The nutrients and energy can't get through because DHT binds to the androgen receptors under the hair follicle.
If the nutrients and energy can't get through, over time your hair shrinks. It gets smaller and smaller and eventually dies.
This is why treatments that successfully block DHT can stop male and female pattern baldness and why this is one of the major goals of our hair restoration programs.
Other Causes of Hair Loss
Traction Alopecia: Loss can occur when hair is braided or pulled too tightly into hairstyles such as pigtails or cornrows. And the traction from hair weaving can also cause hair to fall out.
Thyroid: Thyroid is another issue for many people. The thyroid stores and produces hormones that affect the function of the organs in our bodies. Either hypothyroid or hyperthyroid disease causes hair to weaken and break. Often treatment of the thyroid condition can cause hair to re-grow.
Iron deficiency anemia is also common for a lot of people, both men and
women. Iron deficiency anemia decreases oxygen delivery to the entire
body, which causes the hair loss.
Hormonal Changes in Women: Also, as a woman approaches middle age, menopause can cause hormonal imbalances that contribute to hair loss. Natural estrogen protects a woman’s hair, so when estrogen levels decline during menopause the hair starts thinning. Hormonal changes that cause hair loss can also occur in women because of pregnancy, birth control pills, or other illnesses.
Chemicals: Many of the things we eat including the chemicals and preservatives in our food can cause hair loss. And tobacco smoke contains lethal and damaging chemicals. So, smoking or being exposed to second hand smoke can accelerate hair loss in otherwise healthy individuals.
Stress: Contrary to popular belief, stress does not really cause hair loss, it just makes the already existing condition worse. It can be a contributing factor along with the other causes of hair loss, so if you return to your normal stress-free routine, your hair may start growing again.
Chemical Straightening: Straightening your hair does not really cause hair loss, as much as it causes root damage. However, if you are pulling really hard, you can eventually cause damage. If you're chemically straightening or relaxing the hair, the chemicals can definitely cause hair loss, especially over-the-counter- home relaxers. These are very hard on the hair. So the milder the chemicals, the better.
