Lower lash loss . Try warm compresses, avoid rubbing eyelids or pulling eyelashes, Latisse (bimatoprost) to stimulate growth, check thyroid hormone levels, eat balanced healthy diet.
Eyelash scrubs. A very frequent cause of loss of lower lid eyelashes is a chronic infection in the eyelash oil glands called blepharitis. The main control for this incurable problem is to scrub the eyelid edges with a wet q-tip containing a drop of johnson's no more tears baby shampoo. First use a hot compress then 20 scrubs upper and lower lid margin, then rinse with warm water.
