Eyelash growth is influenced by several biological and external factors that promote the health and lengthening of lashes.
Biological Process of Eyelash Growth
- Eyelashes grow through a natural cycle consisting of three phases: anagen (growth), catagen (transition), and telogen (resting). The anagen phase lasts about 30 to 45 days, during which the eyelash actively grows. Approximately 40% of upper lashes are in this phase at any time, ensuring continuous growth and replacement
- Hormones regulate this growth by triggering protein synthesis, as eyelashes are made of keratin proteins. The average daily growth rate is about 0.12 to 0.14 mm
Factors That Promote Eyelash Growth
- Nourishing Oils: Castor oil is widely recognized for promoting eyelash growth due to its ricinoleic acid content, which may stimulate prostaglandin E2, a molecule linked to hair growth. Coconut oil and olive oil also moisturize and condition lashes, preventing breakage and supporting healthy growth
- Vitamins and Nutrients: Vitamin E acts as a powerful antioxidant that protects lash cells from damage and strengthens them. Omega-3 fatty acids, vitamin A, and vitamin C also support follicle health, collagen production, and overall lash vitality. A balanced diet rich in leafy greens, nuts, fish, and fruits like berries supports eyelash growth from within
- Lash Serums: Products containing peptides, antioxidants, or bimatoprost (an FDA-approved medication for eyelash growth) can stimulate lash follicles and promote longer, thicker lashes
- Eyelash Massage: Gently massaging the eyelids increases blood circulation to hair follicles, delivering essential nutrients that encourage growth
- Proper Care: Avoiding harsh makeup removers, minimizing mechanical stress (like rubbing or tugging), and regularly brushing lashes with a clean spoolie help maintain lash health and prevent premature loss
Summary
Your eyelashes grow due to a natural hair growth cycle regulated by hormones and protein synthesis. Their growth and health can be enhanced by nourishing oils (especially castor oil), vitamins (E, A, C, omega-3), gentle care, eyelash massage, and specialized growth serums. A healthy diet and avoiding damaging habits also contribute to longer, thicker lashes
