Alopecia is a hair loss condition that can affect anyone.

According to the Cleveland Clinic, alopecia can affect the entire body or just the hair on the head.

The loss of 100 hairs a day is part of the normal hair growth cycle, but it is not noticeable because we have new hairs growing to replace the old ones. New hair doesn't grow to replace the hair that's fallen out, which leads to true hair loss. According to the American Hair Loss Association, Americans spend more than $3.5 billion each year trying to treat hair loss.

Symptoms & causes

Most people have hair that grows about a half-inch per month, and most of it is growing at any given time. After two or three months, the dormant hair falls out and the other follicles begin to grow new hair.

Hair loss and shedding are different things. When you lose more hair than normal, new hair is still growing in, and when you lose more hair than normal, new hair is not growing back. During times of stress, people may temporarily lose hair, according to the AAD.

It takes a while for hair to reach a certain length where you can see it, and it still doesn't feel good.

There are a wide variety of factors that can cause hair loss.

This is the most common cause of hair loss and affects both men and women. It is also referred to as male-pattern baldness or female-pattern baldness. This type of hair loss often follows an expected pattern, including a balding hair line in men and a hair loss on the crown of the skull in women. According to AAD, certain genes may cause the hair to shrink and stop growing.

The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) says that an immune system disorder called alopecia areata has no cure. It results in hair loss in small patches on the head. According to NIAMS, most people with the condition develop it in the teen or young adult years. Alopecia areata can cause loss over the entire body.

Hair treatments that use rubber bands, rollers or barrettes can cause hair to grow out of control. Chemicals such as dyes, bleaches, straighteners, and permanent wave solutions can be wrongly used. Permanent hair loss can be caused by damage.

In women, hormonal shifts from birth control pills, pregnancy, childbirth, menopause or hysterectomy can cause more hair follicles than normal to enter the dormant phase.

Illness or surgery can cause the body to temporarily cease non essential tasks such as hair production. Specific conditions can also cause it, such as iron deficiency or severe infections.

Cancer chemotherapy, which attacks hair follicles in its attempt to kill all fast-growing cells around the body, is a well-known reason for hair loss. Some of the medications that have side effects include hair loss, high blood pressure, and gout. There are excessive levels of vitamins A and B.

Excess calories can temporarily stun hair follicles to stop growth. This can happen from not getting enough vitamins or minerals.

Slower hair growth is a natural effect of aging.

With age, women lose hair on the top of the head or the temples, but don't go completely bald. Men are more likely to lose hair on their temples than women are.

According to Harvard Medical School, certain infections can cause hair loss, including tinea capitis, which causes a form of patch hair loss.

A history of medical or stress-related events will be taken by the Dermatologists to see what has been going on in the person's life.

If the hair loss is caused by an auto Immune disease, the dermatologist can take a small patch of skin and send it to a Pathologist.

Day said that examining the hair and follicle can help determine if someone has a disease.

Treatment & medication

The hair loss remedies range from mild to extreme. Depending on how much hair is gone and how high a priority it is to replace it.

According to the Cleveland Clinic, treatments include:

Wigs and hair weaves are usually expensive and can either cover the head or add hair to restore the appearance of a full head of hair. Cancer patients and those with temporary hair loss can use them.

minoxidil can be used on the skin to restore hair growth in people with hereditary hair loss. It is applied directly to the skin. It is only for men and comes in pill form. It may take up to six months to find out if the medications are working.

Steroids can calm follicles damaged by harsh chemicals or excessive pulling.

Men are more likely to be candidates for hair-replacement techniques because their hair loss is usually limited to one or two areas of the body. One to 15 hairs per disc-shaped graft is a procedure. Bald skin is removed from the scalp so hair can be stretched to fill in the bald areas. Swelling, bruised and headaches are some of the side effects.

Day said that hair-growth laser treatment can help improve growth. She said that people see results when they combine laser treatment with another intervention. Treatments range in price from $30 to $3,000, she said.

Natural and alternative therapies

Many alternative therapies are not supported by medical research and may not help hair regrowth.

If your blood tests show that you don't have enough of certain vitamins and minerals, a dermatologist may recommend that you take a supplement. If you have normal levels of vitamins and minerals in your blood, you shouldn't take supplements that have too much of them.

Discuss any alternative treatments with your doctor.

Latest treatment developments

The drug Tofacitinib is approved to treat adults with arthritis, but a growing number of cases suggest that it can also treat a condition in which people lose all of the hair on their body because their immune system attacks hair follicles, Live Science previously reported.

According to a statement from Yale University, a 25-year-old man was prescribed the drug because he had heard it worked in mice. After three months of treatment, the man had regrowth of his hair on his head, as well as regrowth of hair on his body.

Day did not treat this patient, but he said it was exciting.

Researchers hope to figure out how Tofacitinib works soon. They may be able to learn which biological pathways lead to hair loss.

Clinical trials are taking place around the country to see if the drug works for hair loss. The study gave Tofacitinib to 66 people. Half of the people regrew some hair, and one-third had more than 50% of the hair on their scalp grow back, according to a study published in the journal JCI Insight.

Day said that researchers are still working to determine the best dose needed, whether the results are lasting, and whether they can develop a topical form of the drug. She said that patients should be aware of the side effects of Tofacitinib. According to Pfizer, it is associated with an increased risk of serious infections, as well as stomach and intestinal tears.

Researchers are looking at ways to clone hair or use stem cell therapy to treat a condition.
