Why eyelashes become thin and how to maintain their thickness

Maintaining eyelash density and strength depends on a combination of dietary habits, hygiene, and the correct use of cosmetic tools. While home care cannot change genetic length overnight, specific techniques can minimize breakage and preserve the natural thickness of the lashes. Nutrition and Daily Habits Since eyelashes are primarily composed of the protein keratin, strict diets can impact their density. To prevent premature fallout, the body requires amino acids found in meat, fish, eggs, and legumes. Kseniya Anisimova, a skin care specialist, notes that hair follicle quality is linked to tissue nutrition and microcirculation. She warns against applying products not intended for eyes—such as hair conditioners or baby powder—as these can cause severe irritation to the mucous membranes. Physical friction during sleep also contributes to lash loss and kinking. To maintain shape, it is recommended to comb lashes with a clean, dry brush after washing to untangle them and set their direction.
