12 Things You Probably Didn’t Know About Your Hair
1. Like all mammals, there are hair follicles all over our body, except only the palms and soles of the feet.
2 . The condition of hair follicles can change during puberty and pregnancy due to hormones. Stem cells that regulate hair growth play a role in the basis of hair follicles.
3. There are 3 stages in hair growth. Anagen phase: growth phase, catagen phase: resting phase and telogen phase is the shedding phase (like a snake shedding its skin).
4. The anagen phase length of your hair determines how long hair growth will take, and this is determined by genetic makeup. Eyebrows have a shorter anagen phase than our hair, which explains why eyebrows don’t grow to our hair length.
5. The proportion of hairs that are in the telogen (shed) phase at any given time is normally 15%, but if the patient has a high fever, thyroid disease or anemia, or consumes too much selenium food, the hair may begin to thin even further. This condition is called telogen effluvium.
6. When a woman is pregnant, the transition to the anagen phase increases and the hair grows larger and appears brighter, and after childbirth, the hair goes into the telogen phase and shedding begins.
7. Few products and treatments (including lasers, shampoo and supplements) have the ability to increase hair growth.
8. Minoxidil can help with hair loss caused by stress, diet, post-pregnancy, or a short-term problem.
9. Stress can trigger hair to enter the telogen phase.
10. Excessive diet and exercise can cause hair loss. A lack of essential protein affects hair and nails, often accompanied by brittle nails and extremely dry hair.
11th . Some drugs such as antidepressants, birth control drugs, especially cholesterol-lowering statin group can cause hair loss. Some doctors state that thyroid and diabetes medications can cause hair thinning or loss.
12 . Hair loss or thinning is very common during menopause, but doctors still do not fully understand the full role of estrogen. There seems to be a genetic link in this type of hair loss and it is more resistant to treatment.
If you are experiencing any problems such as hair loss or thinning, you can get the best professional help from a dermatologist. Dermatologists are trained to identify the cause of hair loss, to help, and to detect other symptoms on the skin and nails that may be associated with it.
