The lifespan of eyebrow hair lasts an average of four months
Again, we bring you another eyebrow fact. The lifespan of eyebrow hair lasts an average of four months long. This is the average time it takes for the hair to fall off and grow back. Also, research has shown that when you overpluck your eyebrow, the eyebrow will find it difficult to reach its whole life span.
So, if you enjoy plucking your eyebrows to give them a particular shape, you may be doing your eyebrow more harm than good. If you are looking to speed up the growth of your eyebrows, massage them with coconut oil.
