If you’re dealing with thinning hair or male pattern baldness, this might be right up your alley, whether you’re a man or a woman. It works best if you catch the hair loss early on. The golden rule here is: the sooner you start using it, the better your results will be! On top of that, guys looking to patch up or grow a thicker beard have been using it with great success, even though it’s technically only FDA-approved for use on the scalp.
