Causes of hair loss

Hair loss can affect only your scalp or your entire body, and it can be temporary or permanent. It could be the result of genetics, hormonal changes, medical conditions, or a normal part of aging. Anyone can lose their hair.

Baldness usually refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness. Some people prefer to let their hair loss run its course without treatment and without concealment. Others may cover it up with hairstyles, makeup, hats, or scarves. Still others choose one of the treatments available to prevent further hair loss or restore growth.

Causes of hair loss :-
1- Hereditary hair loss
Both men and women suffer from this type of hair loss, and it is the most common cause of hair loss worldwide. Regardless of whether it affects a man or a woman, the medical term is androgenic alopecia.
Regardless of the term you use, this means that you have inherited the genes that cause your hair follicles to shrink (what each hair springs from) and thus stop hair from growing. Contraction can start in the early teens, but it usually starts later in life.

Usually the first noticeable sign of hereditary hair loss in women is general thinning or partial widening.
When a man suffers from hereditary hair loss, the first sign is often a receding hairline or a bald spot on the top of his head.

Is regrowth possible?
Yes, the treatment can help stop or slow hair loss, as well as regrow hair. The earlier treatment is started, the better treatment will be, and without treatment, hair loss will continue.

2- age
With advancing age, most people notice some hair loss due to slowed hair growth. At some point, hair follicles stop growing hair, causing scalp hair to thin. Hair also begins to lose its colour. A woman’s hair line naturally begins to recede.

Is regrowth possible?
An early detection treatment helps some people regrow their hair.

3- Alopecia areata
Alopecia areata is a disease that develops when the body’s immune system attacks hair follicles (holding hair in place), causing hair loss. You can lose hair anywhere on your body, including your scalp and inside your nose and ears. Some people lose their eyelashes or eyebrows.

Is regrowth possible?
Yes. If your hair fails to grow on its own, treatment may help stimulate regrowth.

4- Cancer treatment
If you receive chemotherapy or receive radiation therapy on your head or neck, you may lose all (or most) of your hair within a few weeks of starting treatment.

Is regrowth possible?
Hair usually begins to grow within months of the end of chemotherapy or radiotherapy to the head or neck. Dermatologists can offer medication to help hair grow more quickly.

Can it be prevented?
Wearing a cooling cap before, during, and after each chemotherapy session may help prevent hair loss.

5- Childbirth, illness, or other stress
A few months after giving birth, recovering from an illness, or having surgery, you may notice a lot of hair in your brush or on your pillow. This can also happen after a difficult time in your life, such as a divorce or the death of a loved one.

Is regrowth possible?
If the stress stops, your body will adapt and stop over-eliminating. When hair loss stops, most people see their hair regain its natural fullness within 6 to 9 months.

6- Hair care
If you dye, curl or straighten your hair, it can damage your hair. Over time, this damage can lead to hair loss.

Is regrowth possible?
You can change the way you care for your hair, which will prevent hair loss. Once a hair follicle is destroyed, hair cannot grow out of that follicle. Having many damaged hair follicles leads to permanent bald spots.

7- Hormonal imbalance
A common cause of this defect is polycystic ovary syndrome (PCOS). It leads to cysts on a woman’s ovaries, along with other signs and symptoms that can include hair loss. Stopping some types of birth control pills can cause a temporary hormonal imbalance. Women who develop a hormonal disorder can have thinning hair (or hair loss) on the scalp.

Is regrowth possible?
Treatment may help.
