Why are my eyelashes falling out?

The lifespan of an eyelash is relatively short and does not exceed three months. It is therefore normal, as part of the hair growth cycle, for an eyelash to fall out so that it can be replaced by another. However, in the event of more pronounced loss, it is important to investigate the underlying cause of the problem.

Eyelash loss: A possible medical cause.

Certain dermatological or ocular disorders may be involved. Inflammatory diseases of the skin or hair follicle can disturb the anchoring of the eyelash within the follicle. In the case of alopecia areata, for example, an autoimmune reaction targets the hair follicles and leads to local inflammation that may interrupt eyelash growth. Infections may also be implicated: certain fungal infections, such asTinea blepharociliaris, affect the eyelash follicles and can cause them to fall out. In other situations, eyelash loss may occur secondary to intensive medical treatments, particularly chemotherapy or radiotherapy, which disrupt rapidly dividing cells, including those of the hair follicle.

Eyelash loss: A potential internal cause.

Internal imbalances can also weaken the eyelashes. Hair follicles are particularly sensitive to the body’s nutritional status. An inadequate diet or deficiencies in essential micronutrients, particularly iron, zinc, or vitamins A or C, can alter the quality of the keratin produced and disrupt the eyelash growth cycle. Stress is also frequently mentioned. Although it does not act directly on the eyelashes, significant stress can alter hormonal balance and promote the premature entry of follicles into the shedding phase.

Eyelash loss: certain behaviours may be responsible.

Finally, certain everyday habits or cosmetic practices can weaken the eyelashes. A make-up removal routine that is too vigorous, repeated rubbing or the use of irritating products can damage the follicles or break the lashes at their base. Eyelash extensions, which are very popular for enhancing the eyes, may also play a role. This technique involves attaching synthetic fibres to the natural lashes using an adhesive. A survey conducted among 140 users of eyelash extensions showed that more than half of the participants experienced irritation or burning during the procedure, and 60% reported discomfort after application. In addition, a majority observed thinning or discolouration of their lashes after the extensions were removed.

The weight of extensions, exposure to glues, and repeated handling are all factors that can weaken the eyelashes and promote their loss.

When eyelash loss becomes unusual, the first step is to identify and correct the underlying cause.

If the loss is linked to a dermatological condition, an infection or a systemic disease, medical management may be required. These cases are, however, relatively rare. Most often, eyelash loss is associated with daily habits or imbalances in the body. Make sure you follow a varied and balanced diet, enabling the body to receive all the nutrients it needs. If in doubt, it is best to avoid self-medication. Discuss your concerns with your doctor so that they can determine whether or not you are suffering from a deficiency.

Another important point in preventing eyelash loss is: to be gentle with the eyelid area. Overly vigorous make-up removal repeated rubbing of the eyes, or the use of irritating products can weaken the eyelashes and speed up their loss. Remove your make-up gently, without pressing too hard or rubbing your eyes, and use mild products. It can also be helpful to take breaks from certain cosmetic practices, such as eyelash extensions or frequent use of false eyelashes, to allow the lashes time to renew themselves under optimal conditions.

It is better not to disrupt the natural regrowth cycle of the eyelashes in the event of sudden loss. While it may be tempting to opt for the application of false eyelashes in a salon, the substances used to attach them risk further weakening this already highly sensitive area of the eye contour. Whatever the cause of the eyelash loss, they will grow back, at their own pace, and the eyes will regain their usual appearance. If such episodes start to occur regularly, then seeking medical advice may be necessary.
