Although, there is only anecdotal information (not any clinical data) that states that Castor Oil helps hair grow, I recently used it on my eyelashes after an eyelash curler cut them off. I used the Castor Oil for two weeks and they grew back.
Castor oil helps by improving circulation to the follicles on the scalp which may be why it works so well.
Also, on eyebrows or scalp add a little peppermint which is backed by an NIH study for Hair Growth. Peppermint stimulated the follicles.
