For guys looking to treat male pattern baldness or grow some facial hair, 5% is the sweet spot. Studies have actually shown that the 5% solution brings significantly better results than the 2%. For women treating AGA, it’s usually recommended to start with the 2% strength. If that isn’t quite doing the trick after a few months, stepping up to 5% is a solid option. Just keep in mind that the stronger the dose, the higher the chance of getting some minor hair growth elsewhere on your body since the medication absorbs into your bloodstream.
