Frequently losing eyelashes can be caused by a variety of factors, including physiological, pathological, and external factors. Here is a detailed analysis:

- Normal Eyelash Renewal Cycle: Eyelashes, like other hairs on the body, have a natural growth cycle that consists of anagen (growth phase), catagen (transition phase), and telogen (resting phase). At the end of the telogen phase, eyelashes will naturally fall out to make way for new ones. On average, eyelashes have a growth cycle of about 3-5 months, and it is normal to lose a few eyelashes every day as part of this cycle.
- Hormonal Changes: Fluctuations in hormones can affect the growth and health of eyelashes. For example, during pregnancy, childbirth, menopause, or when taking hormonal medications, hormonal imbalances may occur in the body. This can disrupt the normal growth cycle of eyelashes, leading to increased shedding.
- Ophthalmic Diseases: Some eye diseases can cause eyelash loss. Blepharitis, which is the inflammation of the eyelids, can affect the hair follicles of the eyelashes, leading to eyelash shedding. Conjunctivitis, if severe or chronic, may also have an impact on the surrounding tissues, including the eyelashes. In addition, trichiasis, where the eyelashes grow in the wrong direction and rub against the eyeball, can cause eyelashes to break and fall out.
- Skin Diseases: Certain skin diseases that affect the eye area can also lead to eyelash loss. For example, seborrheic dermatitis can cause excessive oil secretion around the eyes, clogging the hair follicles and affecting the growth of eyelashes. Psoriasis and eczema, when they occur around the eyes, can cause skin inflammation and scaling, which may also affect the health of the eyelashes.
- Systemic Diseases: Systemic diseases such as hypothyroidism and alopecia areata can also manifest as eyelash loss. Hypothyroidism leads to a slowdown in the body's metabolic rate, affecting the growth of hair including eyelashes. Alopecia areata is an autoimmune disease that causes the immune system to attack the hair follicles, resulting in hair loss not only on the scalp but also on the eyebrows and eyelashes.
- Improper Makeup Removal: Using harsh makeup removers or rubbing the eyes vigorously when removing makeup can cause mechanical damage to the eyelashes, leading to breakage and loss. In addition, if makeup remover residues remain on the eyelashes, they can clog the hair follicles and affect the health of the eyelashes.
- False Eyelash Use: Frequent use of false eyelashes, especially if they are not applied or removed properly, can put stress on the natural eyelashes. The adhesive used to attach false eyelashes may also irritate the eyelash follicles and cause eyelashes to fall out.
- Eye Habits: Some bad eye habits can also cause eyelash loss. For example, frequently rubbing the eyes due to eye itching or discomfort can cause mechanical damage to the eyelashes and hair follicles. Wearing contact lenses for a long time without proper care may also affect the health of the eyes and eyelashes.
If the phenomenon of frequent eyelash loss is accompanied by other symptoms such as eye redness, swelling, pain, or excessive hair loss in other parts of the body, it is recommended to seek medical attention in a timely manner to identify the cause and receive appropriate treatment.
