Girls, or even guys I have to ask...?

Does anybody know of some tips or ideas for longer healthier hair? Pills, shampoos, product, homemade remedies, style ideas (heard a ponytail is good for hair growth?) seriously, any idea would be helpful! Is there anything I could get at a salon to help out? Besides a trim... Just anything for me to try and get some long beautiful locks! Thanks!
