I know they say it's safer but some say it absorbs into your skin hence getting into ur bloodstream. ..who knows if this doesn't work I will try that route ( I still got 2 bottles left in the closet)...n maybe a derma roller.
If it does get absorbed, I think it must be a very low amount. And perhaps those getting sides are using high amounts twice daily all over their scalp.
I don't notice any extra hair growth on my body and no sexual side effects at all.
However, I think Rogaine foam might have higher chances of side-effects for some reason compared to the liquid.
