Alopecia Areata

At Mid-County Dermatology, we are experts in the diagnosis and treatment of alopecia areata, a common autoimmune disorder that causes hair loss. Alopecia areata is characterized by the sudden onset of round, patchy hair loss on the scalp or other areas of the body. While it can affect people of any age, it is most commonly diagnosed in people between the ages of 15 and 29.

The exact cause of alopecia areata is not fully understood, but it is thought to be related to a combination of genetic, environmental, and immunological factors. Some research suggests that alopecia areata may be triggered by stress, infections, or certain medications, although the exact link between these factors and the development of alopecia areata is not yet clear.

Alopecia areata is an autoimmune disorder, which means that it occurs when the body's immune system mistakenly attacks healthy cells. In the case of alopecia areata, the immune system attacks the cells in the hair follicles, leading to hair loss. The exact mechanism by which the immune system attacks the hair follicles is not fully understood, but it is thought to be related to the presence of certain antibodies in the blood.

Alopecia areata is typically diagnosed through a physical examination of the affected area and a thorough medical history. In some cases, a dermatologist may also perform a scalp biopsy to confirm the diagnosis. Alopecia areata is classified into several different types based on the extent and pattern of hair loss, including alopecia areata monolocularis (one patch of hair loss), alopecia areata multilocularis (multiple patches of hair loss), and alopecia areata totalis (complete hair loss on the scalp).

There is no known cure for alopecia areata, but there are several treatment options that can help to slow the progression of hair loss and stimulate new hair growth. These treatment options include:

  1. Topical medications: Topical medications, such as minoxidil and corticosteroids, can be applied directly to the affected area to stimulate hair growth and reduce inflammation. These medications are typically most effective when used early in the course of the disease. Minoxidil is a medication that is applied topically to the scalp and works by promoting blood flow to the hair follicles and increasing the production of a protein called keratin, which is essential for healthy hair growth. Corticosteroids are medications that are used to reduce inflammation and are often used to treat alopecia areata. They can be applied topically as a cream, lotion, or ointment, or they can be injected into the affected area.

  2. Injectable medications such as intralesional corticosteroids

  3. Oral medications: Oral medications, such as isotretinoin, mycophenolate mofetil, minxoidil, Xeljanz, and cyclosporine, can help to slow the progression of hair loss and stimulate new hair growth. These medications are typically reserved for more severe cases of alopecia areata or for cases that do not respond to topical treatments. Isotretinoin is a medication that is used to treat severe acne, but it has also been shown to be effective in the treatment of alopecia areata. Cyclosporine is an immunosuppressive medication that is used to suppress the immune system and is often used to treat alopecia areata.

  4. Light therapy: Light therapy, also known as phototherapy, involves the use of lasers or other light sources to stimulate hair growth. This treatment is typically administered by a dermatologist in a clinical setting. Light therapy can be administered using a variety of different light sources, including lasers, intense pulsed light, and narrowband ultraviolet B (UVB) light.

  5. Immunotherapy: Immunotherapy involves the use of agents that stimulate the immune system to attack the cells that cause hair loss. This treatment is typically administered by a dermatologist in a clinical setting. Immunotherapy can be administered using a variety of different agents, including contact immunotherapy, diphencyprone (DPCP), and squaric acid dibutylester (SADBE).

  6. Hairpieces and wigs: In cases of extensive hair loss, hairpieces and wigs can provide a temporary solution to conceal the affected area. These options can be especially helpful for people who are self-conscious about their appearance or who have difficulty finding other treatment options that are effective. Hairpieces and wigs can be made from a variety of different materials, including synthetic fibers, human hair, and animal hair. They can be custom-made to match the color and texture of the individual's natural hair and can be worn on a full-time or part-time basis.

  7. Platelet-rich plasma (PRP) therapy: PRP therapy involves the use of the patient's own platelets to stimulate hair growth. Platelets are cells that are found in the blood and are responsible for helping the blood to clot. They also contain growth factors that are essential for tissue repair and regeneration. In PRP therapy, a small amount of the patient's blood is drawn and then processed to isolate the platelets. The platelets are then injected into the affected area to stimulate hair growth.

  8. Hair transplantation: Hair transplantation is a surgical procedure that involves the transfer of hair from one area of the scalp to another. It is typically used to treat male-pattern baldness, but it can also be used to treat alopecia areata in some cases. There are several different techniques that can be used for hair transplantation, including follicular unit transplantation (FUT), follicular unit extraction (FUE), and scalp reduction.

  9. Alternative therapies: Some people with alopecia areata may choose to try alternative therapies, such as acupuncture, herbal remedies, or supplements, in an attempt to stimulate hair growth. While there is limited scientific evidence to support the effectiveness of these treatments, some people may find them helpful. It is important to speak with a dermatologist or other healthcare provider before starting any alternative therapy to ensure that it is safe and appropriate.

The prognosis for people with alopecia areata can vary widely, as the disease can be unpredictable and can affect each person differently. In some cases, hair loss may be temporary and may spontaneously regrow without treatment. In other cases, hair loss may be more persistent and may require treatment to stimulate hair growth.

It is important to note that alopecia areata is not a life-threatening condition and does not have any negative impact on a person's overall health. While hair loss can be emotionally distressing, it is important to remember that there are many treatment options available that can help to slow the progression of hair loss and stimulate new hair growth.

With the right treatment approach and support from our dermatology team, many people with alopecia areata are able to successfully manage their condition and achieve significant hair regrowth. It is important to work with a dermatologist or other healthcare provider to develop a treatment plan that is tailored to your individual needs and goals.

It is also important to remember that alopecia areata is not contagious and cannot be transmitted from one person to another. It is a common condition that affects millions of people around the world, and there is no reason to feel ashamed or isolated because of it.

Overall, while alopecia areata can be a challenging condition to manage, it is important to remain hopeful and to stay positive. With the right treatment approach and support, it is possible to successfully manage alopecia areata and achieve significant hair regrowth.
