Eyebrow alopecia : Causes and treatments
Eyebrow hair loss is a common phenomenon. This can be due to some reasons : hormonal changes or nutritional deficiencies, infection, skin conditions, stress or even an overactive immune system that attacks the hair follicles. This type of hair loss has different possible treatments depending on the case of each patient.
What are the causes of eyebrow alopecia ?
The specific causes of eyebrow hair loss include :
The same autoimmune disease that is often responsible for scalp hair loss can also affect your eyebrows. In this case, your immune system targets and attacks your eyebrow hair follicles, slowing or stopping hair production and causing eyebrow alopecia.
Your body needs a healthy diet with a balance of carbohydrates, proteins, fats, amino acids, vitamins and minerals. Since some of these nutrients support or influence hair growth, their absence could lead to hair loss. For example, a deficiency in vitamins C, E, B-12, D, in iron, in cysteine and/or omega-3 could lead to hair loss including eyebrow hair.
Skin conditions such as eczema and psoriasis can affect the hair growth. Any type of dermatitis can prevent hair follicles from growing normally.
The thyroid gland, located at the front of the neck, produces hormones that regulate the metabolism. When it produces too much or too little hormone, your body's normal processes including hair growth, can be disrupted.
Excessive stress or anxiety
Psychological problems are known to contribute to eyebrow hair loss. If you have recently experienced a traumatic event or a major lifestyle change, this may be the cause of eyebrow hair loss.
This is a temporary but a dramatic hair loss that occurs when your normal hair growth cycle is interrupted. This can be due to stress, some changes in your diet, medication, hormonal changes or other factors.
Excessive hair removal
This practice creates a minor trauma to the follicle which can prevent hair from growing in that repeatedly depilated area.
Eyebrow loss can be the result of trauma, burns (chemical or thermal) and skin conditions usually involving problems with the immune system attacking the body's own tissues and inducing the formation of scar tissue affecting the hair regrowth in the affected area.
In general, as women's estrogen and men's testosterone levels decline in their forties and beyond, both sexes may begin to experience thinning of the hair on the scalp and the eyebrows.
Chemotherapy is specifically designed to affect all the rapidly dividing cells including the hair follicles. As a result, chemotherapy can attack the hair follicle and cause hair loss in the eyebrows.
How do I get back my eyebrows ?
Once the doctor has diagnosed the cause of your eyebrow loss, he or she will recommend you the most appropriate treatment to restore your eyebrows to their natural state.One of the most effective options for this is eyebrow transplant. Similar to restoring hair from the scalp, this procedure involves the extraction of the hair follicles from the scalp while moving them into the sparse area of the eyebrows.

Eyebrow implant: procedure sequence
The surgery usually lasts between 2 and 3 hours depending on the number of follicular units that will be transplanted. It is performed under local anesthesia. Like all cosmetic surgery, eyebrow transplant involves several steps. First of all, the surgeon begins by drawing a drawing of the new eyebrows. Then, he applies local anesthesia in the donor and recipient area so that the entire process is completely painless for the patient. Generally, surgeons use the follicular unit extraction (FUE) technique because it gives less visible scars than the FUT technique.Thus, using the FUE method, the surgeon removes the hair follicles one by one from the donor area, which is the scalp, and implants them into the hairy eyebrow area. Usually, depending on the size of the area.
