Physical stress

Any kind of physical trauma—surgery, car accident or illness can cause temporary hair loss. This can trigger a type of hair loss called telogen effluvium. It is important to considered that hair has a programmed life cycle: a growth phase, rest phase and shedding phase. A dermatologist in New York City said that when you have a really stressful event, it can shock the hair cycle and pushing more hair into the shedding phase.

Pregnancy

Pregnancy is one example of the type of physical stress that can cause hair loss since the hormones become unstable. It is seen more commonly after the baby has been delivered rather than actually during pregnancy because giving birth is pretty traumatic.

Too much vitamin A

Taking too much vitamin A-containing supplements or medications can trigger hair loss, according to the American Academy of Dermatology. The Daily Value for vitamin A is 5,000 International Units (IU) per day for adults and kids over age 4; and the supplements can contain 2,500 to 10,000 IU.

Lack of protein

According to the American Academy of Dermatology, if you don’t get enough protein, your body may start to ration protein by shutting down hair growth,. This can happen about two to three months after a drop in protein intake.

Heredity

Hair loss also caused by heredity factors. If you come from a family where women started to have hair loss at a certain age, then you might be more prone to it.

Female hormones

We have known that hormones also responsible for hair loss. For female, there are other factors that cause hormones become unstable such as switching or going off birth-control pills. The change in the hormonal balance that occurs at menopause may also have the same result. Mark Hammonds.MD, a dermatologist with Scott & White Clinic in Round Rock, Texas explain it, “The androgen  receptors on the scalp becoming activated, the hair follicles will miniaturize and then you start to lose more hair.”

Emotional stress

Emotional stress is less likely to cause hair loss than physical stress, but it can happen. More often, though, emotional stress won’t instantly causes the hair loss. It will increase a problem that’s already there.

Chemotherapy

Some of the drugs and therapy are used to beat back cancer, unfortunately they also cause the hair to fall out. One example is chemotherapy. A dermatologist said that chemotherapy is like a nuclear bomb that is done to destroy rapidly dividing cells which means cancer cells, but also rapidly dividing cells like hair.

Antidepressants, blood thinners, and more

Certain other classes of medication may also promote hair loss, such as certain blood thinners and the blood-pressure drugs known as beta-blockers or some drugs like methotrexate, lithium, nonsteroidal anti-inflammatory drugs (NSAIDs) including ibuprofen, and possibly antidepressants.

Over-styling

Over-styling or an extreme hairstyling also can cause hair loss. Vigorous styling and hair treatments over the years can cause your hair to fall out. This kind of ex-include tight braids, hair weaves or corn rows, chemical relaxers to straighten your hair, hot-oil treatments or any kind of harsh chemical or high heat. These practices can affect the hair root so that your hair might loss and even worse, it cannot grow back.

Aging

Ages is one of factors that cause hair loss. It’s not uncommon to see hair loss or thinning of the hair in women as they enter their 50s and 60s. Experts aren’t sure why this happens.

Another Factors :

Autoimmune-related Hair Loss

This is also called alopecia areata and basically is a result of an overactive immune system where the body gets confused, they may see the hair as foreign and targets it by mistake then cause hair loss.

Lupus

Other autoimmune diseases such as lupus can also cause hair loss. It is also in case of mistaken identity: overzealous immune cells attack the hair. Unfortunately, once hair loss is caused by this factor, the hair will not grow back.

Sudden weight loss is a form of physical trauma that can result in thinning hair. It seems like the weight loss itself is stressing your body or, weight loss that is caused by eating disorder makes you do not get enough vitamin or mineral and it causes hair loss. In addition, loss of hair along with noticeable weight loss may also be a sign of an eating disorder such as anorexia or bulimia.
