My natural hair growth remedy is based from experience. When I was using petroleum jelly on my lips, there are some of the substance left under my nose. I noticed the growth of hair under my nose. I stop doing it and the hair doesn't grow anymore. I do not touch it or wax it because I don't want to grow it thicker. Because of that, I put a petroleum jelly on my eye brow and it grows, but not that quick. I even put it on the side of my head that is losing hair, and I can feel the growth of hair little by little now. I also uses it on my eye lashes. I put a little of it. Unfortunately, I don't know the logic behind petroleum jelly helping my hair to grow but it really makes my hair grow when I put it on the roots, not on the hair itself. Even aloe vera can make the hair grow oo.
