Traumatic Alopecia

1. Traction Alopecia: Traction alopecia is a form of hair loss caused by repeated pulling or tension on the hair. This can occur due to tight hairstyles, such as braids, weaves, and cornrows, or from wearing hair extensions for extended periods. Traction alopecia often results in hair loss around the hairline, temples, and nape of the neck.
2. Chemical Alopecia: Chemical alopecia occurs when harsh chemicals, such as relaxers, hair dyes, and bleach, damage the hair shaft and hair follicles. This type of traumatic alopecia can result in patchy hair loss, breakage, and thinning of the hair.
3. Thermal Alopecia: Thermal alopecia is a type of hair loss caused by heat styling tools, such as flat irons, curling irons, and hot combs. Prolonged and excessive use of these tools can damage the hair shaft and hair follicles, resulting in hair loss.
4. Mechanical Alopecia: Mechanical alopecia occurs when the hair is subjected to repeated friction, such as from wearing tight hats, helmets, or headbands. This type of traumatic alopecia can result in hair loss around the areas where the hair is repeatedly rubbed or pulled.
5. Trichotillomania: Trichotillomania is a psychiatric disorder characterized by the urge to pull out one’s hair, including eyelashes and eyebrows. This condition can result in patchy hair loss, breakage, and thinning of the hair.
6. Alopecia Areata: Alopecia areata is an autoimmune disorder in which the immune system attacks the hair follicles, resulting in hair loss. Traumatic alopecia can exacerbate the symptoms of alopecia areata, causing hair loss to occur more rapidly and in larger areas.
7. Pressure Alopecia: Pressure alopecia is a type of hair loss caused by prolonged and continuous pressure on the scalp. This can occur due to wearing tight hairstyles or headgear, such as headbands, wigs, or helmets. Pressure alopecia can result in hair loss around the areas where the pressure is applied.
8. Radiodermatitis Alopecia: Radiodermatitis alopecia occurs when radiation therapy is used to treat cancer in the head and neck area. Radiation therapy can damage the hair follicles, resulting in hair loss. This type of traumatic alopecia is usually temporary, and the hair will usually regrow after the radiation therapy is completed.

Causes

Causes of traumatic alopecia, along with details on each cause.

Symptoms

Main symptoms of traumatic alopecia, along with a detailed explanation of each:

1. Hair breakage: Traumatic alopecia often results in hair breakage, particularly at the site of the injury. Hair may appear shorter or uneven due to the breakage.
2. Thinning hair: Traumatic alopecia can also cause hair to become thin or sparse in certain areas. This may be due to repeated trauma to the hair follicles, which can cause them to shrink or become damaged.
3. Patchy hair loss: In some cases, traumatic alopecia can cause patchy hair loss. This can occur when the hair follicles are damaged or destroyed, leading to the formation of small bald spots on the scalp.
4. Scarring: Severe cases of traumatic alopecia can lead to scarring on the scalp. This can be particularly concerning if the scars are permanent and affect the appearance of the hair.
5. Itching and irritation: Traumatic alopecia can cause itching and irritation on the scalp. This is often due to inflammation caused by repeated trauma or injury to the scalp.
6. Redness and inflammation: Inflammation is a common symptom of traumatic alopecia. It can cause the scalp to become red, swollen, and tender to the touch.
7. Burning sensation: Some people with traumatic alopecia report feeling a burning sensation on their scalp. This may be due to the irritation and inflammation caused by the condition.
8. Tenderness: Traumatic alopecia can make the scalp tender to the touch. This can be particularly uncomfortable if the affected area is brushed or touched frequently.
9. Tightness: Tight hairstyles or head coverings can cause the scalp to feel tight and uncomfortable. This can contribute to the development of traumatic alopecia.
10. Headaches: In some cases, traumatic alopecia can cause headaches. This may be due to the tension and strain caused by tight hairstyles or head coverings.
11. Dandruff: Traumatic alopecia can also cause dandruff, which is characterized by flaky, itchy, and irritated skin on the scalp.
12. Sores: Repeated trauma or injury to the scalp can cause sores to form. These may be painful and can lead to scarring if left untreated.
13. Pimples: Traumatic alopecia can cause pimples to form on the scalp. This is often due to inflammation and irritation caused by repeated trauma to the hair follicles.
14. Cysts: In some cases, traumatic alopecia can cause cysts to form on the scalp. These are typically small, fluid-filled sacs that can be painful if they become infected.
15. Ingrown hairs: Traumatic alopecia can cause hairs to grow back into the skin, leading to ingrown hairs. These can be painful and may cause further damage to the hair follicles.
16. Brittle hair: Traumatic alopecia can cause hair to become brittle and dry. This can make it more prone to breakage and further damage.
17. Split ends: Traumatic alopecia can cause split ends to form on the hair. This is often due to repeated trauma or injury to the hair shaft.
18. Changes in hair texture: Traumatic alopecia can cause changes in the texture of the hair. This may include an increase in curliness or coarseness, as well as a decrease in shine and softness.

Diagnosis

Diagnosis and tests for traumatic alopecia and provide a detailed explanation for each one.

1. Physical exam: A physical exam of the scalp is the first step in diagnosing traumatic alopecia. The healthcare provider will look for signs of hair loss, such as thinning or bald patches, and examine the scalp for any signs of inflammation, scarring, or infection.
2. Medical history: The healthcare provider will ask about the patient’s medical history, including any previous injuries, surgeries, or illnesses that may have contributed to the hair loss.
3. Hair pull test: A hair pull test involves gently pulling on a small section of hair to see how many hairs come out. A positive result, where more than 10% of hairs come out, may indicate a hair loss condition.
4. Trichoscopy: Trichoscopy is a non-invasive diagnostic test that uses a handheld microscope to examine the hair and scalp. This can help identify the pattern of hair loss and any underlying scalp conditions.
5. Scalp biopsy: A scalp biopsy involves removing a small piece of scalp tissue for examination under a microscope. This can help identify the underlying cause of hair loss, such as scarring or inflammation.
