7 Causes of Eyebrow Hair loss

Causes of Eyebrow Hair Loss

The possible causes of eyebrow hair loss are as per the following:

1. Normal Aging

As a person get older, he/she may notice hair loss or thinning affecting the head, eyebrows, eyelashes, and elsewhere.

As one age, over a specific time, some hair follicles stop producing hair, and the hair shafts become finer. The hair also begins to lose its color, turning in to white or gray.

2. Hormonal Imbalances

An imbalance of thyroid hormones can cause eyebrow hair loss. This is linked to the following conditions:

• hyperthyroidism
• hypothyroidism

Both of these two types of thyroid imbalance are linked to eyebrow hair loss. Specifically, in hypothyroidism, a person may notice hair loss in the outer third of the eyebrow, which is the thinnest part that points toward the ears.

Thyroid-related hair loss is temporary, and the hair returns to its usual fullness once thyroid levels return to normal.

3. Autoimmune Conditions

Autoimmune conditions develop when the immune system mistakenly attacks its own body cells. The immune system sometimes may attack healthy cells that contribute to hair growth. This subsequently leads to thinning hair or patches of hair loss.

Autoimmune conditions that can cause hair loss include:

• Alopecia areata – A condition that causes patches of hair loss on the head. And sometimes it may affect other areas of the body, which can include the eyebrows
• Frontal Fibrosing Alopecia – It is a form of alopecia that mainly affects people after menopause; in some cases, eyebrow hair loss occurs before scalp hair loss.
• Discoid Lupus Erythematosus–  It is a chronic autoimmune condition that causes skin sores, scarring, and hair loss on the face and eyebrows

4. kin Conditions

Healthy skin is important for healthy hair. This is because hair grows directly from follicles in the skin.

Certain skin conditions can cause itchy, flaking skin rashes. People may lose eye brow hairs as a result of some skin problems like, skin inflammation, dry skin, and rubbing or itching the area around the eyebrows.

Common skin conditions that can cause itchy rashes and eyebrow hair loss include:

• atopic dermatitis
• psoriasis
• seborrheic dermatitis

5. Nutritional deficiencies

The food a person eats has a substantial impact on their skin and hair health. The body needs certain nutrients to create healthy hair.

The following nutritional deficiencies could also be the reason for your eyebrow hair loss:

Fatty Acid Deficiency: According to the study, having a lack of fatty acids — which are present in fish, nuts, and seeds — in the body may cause eye brow hair loss.

Biotin Deficiency: Not getting enough vitamins like,  biotin can result in thinning hair and a loss of body hair. Biotin is a popular hair growth supplement, but there is limited evidence to support its effectiveness.

Zinc Deficiency: A lack of zinc can lead to hair loss. The authors of a review study say that zinc supplements may help with hair regrowth in people with a deficiency.

6. Medication side effects

Certain medications cause hair loss as a potential side effect, which can also affect the eyebrows. Such medications include:

• acitretin, a retinoid drug that people use to treat skin conditions such as psoriasis
• chemotherapy, a treatment for cancer
• valproic acid, an anticonvulsant drug that treats seizures and bipolar disorder

7. Genetic Conditions

Certain uncommon genetic conditions can lead to eyebrow hair loss. Conditions include:

• Ectodermal Dysplasias: This is a condition affecting the skin, hair, nails, and teeth. This can also cause sparse or missing hair in the eyebrows, eyelashes, and other body parts.
• Netherton syndrome: This condition affects the skin, hair, and overall immune system. It can cause fragile and easily broken hair, called “bamboo hair.” This condition tends to be present from birth.

• amyloidosis
• sarcoidosis
• chemical burns
• trichotillomania, a hair-pulling disorder
