Will cigar ash make facial hair grow faster?
I don’t think so. I think that it might just be coincidence that it “worked” for your friend. There is nothing in a cigar that will make hair grow faster, so I doubt that its products of combustion would have anything. There really isn’t many ways to make hair grow faster, but one way for facial hair is to shave more often. This typically only works once you start growing some facial hair.
Not all hair growth products will suit your hair type. So, it is important that you always buy products according to your hair type. Well, the good part is that there are also natural hair care products which are chemical free and safe for your hair.
