Kk, does using hair pills help grow your hair? if so, how long does it tak to grow a inch?

The average growth of hair is 1/2 inches per month. I haven't tried hair pills, but most of them are similar to multi-vitamins. If you're trying to grow your hair long I would instead recommend taking a multi-vitamin. Getting proper nutrition is key to hair growth. I've also found MSM and primrose evening oil effective.
