Except using bimatoprost based eyelash enhancers, there still is some simple ways to grow long eyelashes.
Firstly, use a special brush or a thoroughly washed brush from an old mascara tube. Use a few drops of vitamin E, and brush your eyelashes to the tips for 5 minutes twice a day. Vitamin E improves blood flow and stimulates hair growth. Secondly, castor, coconut, and olive oils contain fatty acids that provide nutrition to follicles and keep eyelashes healthy. Put a drop of oil on a clean brush or your finger, and apply it to your eyelashes before going to sleep. You can use one oil or mix a composition. Thirdly, petroleum jelly soothes and moisturizes dry eyelashes. Carefully apply a little petroleum jelly with a brush or a finger before going to bed. Avoid eye contact. Wash your face in the morning. Fourthly, green tea contains antioxidants and vitamins, and that is why it is used in cosmetic products and in hair loss treatment. Make a cup of strong green tea, let it cool, and apply it with a cotton pad to your eyelashes twice a day. Last but not the least, aloe juice and flesh are good for hair strengthening and nutrition. Take a fresh aloe leaf, squeeze a few drops of juice, and apply to your eyelashes. Leave overnight, and wash your eyes in the morning. To improve the effect, mix aloe juice with castor or olive oil.
