The eyelash density ranges from 70 to 150 hairs in the upper eyelid and 60 to 80 in the lower eyelid. They grow within a month and last for three months and then falls down. In the eyelash life cycle,

Eyelashes fall down can occur for the following reasons

I will give you four basic solutions

• Have a visit to your ophthalmologist or physician to treat any general diseases or eye diseases
• You can enhance your eyelash density or length  with topical medicines such as eye drops containing "Bimatoprost 0.3" available under several trade names
• Make sure to remove the eye makeup well in the evening, no matter how tired you are (DO NOT sleep while yours make up on) as the cells are rejuvenated in the evening
• All types of mascara, no matter how moisturizing, contains petroleum substances that lead to drying and breaking of eyelashes. The best eye makeup and mascara remover is the pure coconut oil that at the same time moisturizes the skin and eyelashes wonderfully.
