What Causes Alopecia?

Hair loss or alopecia can affect anyone, but it’s more common in men. The condition can occur on the scalp or the entire body, and it can be temporary or permanent. There are several reasons why people experience hair loss, including heredity, hormonal changes, medical conditions, or the natural aging process.

Hereditary hair loss is a common cause of baldness, and it’s typically associated with aging. This type of hair loss often affects men, and it may be accompanied by a receding hairline or a thinning crown. While some individuals choose to accept their hair loss without treatment, others prefer to cover it up with hairstyles, makeup, hats, or scarves.

There are also several treatments available to prevent further hair loss or restore growth. One option is medication, such as minoxidil or finasteride, which can be effective in promoting hair regrowth. Another treatment is hair transplant surgery, which involves transplanting hair follicles from one area of the scalp to another.

In addition to these treatments, there are also several lifestyle changes that can help prevent hair loss. Eating a healthy diet, reducing stress, and avoiding harsh hair treatments and styling products can all promote healthy hair growth.

Hair loss is a common problem that affects people of all ages and genders. There are several types of hair loss, and it can occur suddenly or gradually. The causes of hair loss can vary, and some of the most common ones include genetics, hormonal changes, medical conditions, and certain medications.

One of the most common types of hair loss is gradual thinning on the top of the head. This type of hair loss typically affects people as they age, and it is more common in men. In men, hair loss often starts with the hairline on the forehead receding, while women typically experience a broadening of the part in their hair. An increasingly common hair loss pattern in older women is frontal fibrosing alopecia, which is a receding hairline.

Another type of hair loss is circular or patchy bald spots that can occur on the scalp, beard, or eyebrows. This type of hair loss is often caused by an autoimmune condition called alopecia areata. It can cause itchiness or pain on the skin before hair falls out.

Hair can also become loose suddenly due to a physical or emotional shock, resulting in overall hair thinning that is usually temporary. This type of hair loss is called telogen effluvium, and it can be triggered by stress, surgery, childbirth, or a high fever. Handfuls of hair may come out when combing or washing your hair or even after gentle tugging.

Full-body hair loss is another type of hair loss that can be caused by certain medical conditions or treatments, such as chemotherapy for cancer. The hair usually grows back after the treatment is completed, but it may take several months.

Finally, patches of scaling that spread over the scalp may indicate ringworm. Ringworm is a fungal infection that can cause broken hair, redness, swelling, and oozing. It is important to seek medical attention if you suspect that you have ringworm because it can be contagious and may require treatment with antifungal medication.

Who Does It Affect

Alopecia areata is a condition that can affect anyone, but some individuals are at a higher risk of developing it. One group with an increased risk is those who have a close family member with alopecia areata. Research estimates that around 10% to 20% of individuals with alopecia areata have a family member with the condition. However, this percentage may be higher as many people attempt to conceal their hair loss, and the condition often goes undiagnosed.

Several medical conditions have also been linked to an increased risk of alopecia areata. These include asthma, hay fever, atopic dermatitis, thyroid disease, vitiligo, or Down syndrome. Researchers have yet to determine the exact reason for this increased risk, but they believe it may be due to shared genetic or environmental factors.

Individuals who have been treated for cancer with the drug nivolumab may also be at a higher risk of developing alopecia areata. Although it’s still too early to determine the extent of the increased risk, some cancer patients who have received nivolumab have experienced hair loss a few months after starting treatment. This hair loss, known as nivolumab-induced alopecia areata, is typically viewed as a positive sign that the drug is working. However, it’s important to note that not all cancer patients who receive nivolumab experience hair loss, and the drug is only used to treat specific types of cancer.


The treatment for alopecia depends on the type and severity of the condition. In some cases, hair may regrow without treatment, while in other cases, hair loss may be permanent. However, there are several treatments available that may help to promote hair growth and improve the appearance of the affected area.

One of the most common treatments for alopecia areata is corticosteroids. These medications are available in various forms, including topical creams, injections, and oral tablets. Corticosteroids work by reducing inflammation in the affected area and suppressing the immune system. This can help to prevent further hair loss and promote hair regrowth.

Another treatment option is topical minoxidil, a medication that is applied directly to the scalp. Minoxidil is thought to promote hair growth by increasing blood flow to the hair follicles and extending the growth phase of the hair cycle. It may take several months of treatment before results are noticeable, and the medication must be used continuously to maintain hair growth.

For individuals with extensive or permanent hair loss, hair restoration surgery may be an option. Hair restoration surgery involves transplanting hair follicles from one area of the scalp to the affected area. This procedure can be costly and may require multiple sessions to achieve the desired results.

In addition to these treatments, there are also various natural remedies and alternative therapies that some individuals may find helpful, such as acupuncture, herbal supplements, and dietary changes. However, it’s important to consult with a healthcare professional before trying any new treatment or supplement to ensure that it is safe and effective.
