1. Caster oil
Caster oil comes from the seeds or beans of the caster plant, and are rich in many nutrients including ricinoleic acid. This is a type of fatty acid that reduces inflammation and can in turn promote growth in areas on the eyelid that could be inflamed. Caster oil also stimulates tissue growth, helping to heal wounds — perhaps an eye infection that is blocking eyelash growth.
The oil properties have also been found to reduce dryness and the buildup of dead skin that also deters lashes from growing to their full potential.
To use, put 2 tablespoons of caster oil, and 2 tablespoons of aloe vera gel on a cotton swab. Gently wipe it on lashes without getting in the eye. Leave on overnight, then rinse with a warm cloth rinse in morning. Do this daily for 2-3 months.
