Why do my eyelashes and eyebrows fall out so easily? latisse (bimatoprost) not helping either of them grow

Latisse (bimatoprost): Common causes of eyelashes falling out include immune-related hair loss, allergy to mascara, thyroid conditions, or, most commonly, natural eyelash loss. Latisse (generic name bimatoprost) comes in eyedrop form and is usually used for glaucoma. It has also recently been approved by the FDA to help lengthen eyelashes, but it is not a guarantee that it will work for everyone.
