Does shaving make hair thicker? Well, the scientists from the Mayo Clinic explain that shaving off a hair can make it look stronger and thicker as it grows (because of the lack of natural pointiness mainly), it does not in fact get thicker, darker or stronger. This is a total opposite to what hundreds of years’ worth of granny experience tells us, doesn’t it? Well, it still cannot fight other scientifically explained facts. For example, shaved hairs can become ingrown and create a sort of infection and irritation of the skin. That is if you cut against the natural direction of growing (which is what should be done for a close shave). Additionally, when shaved, some hairs start accumulating and more than one can share the same hole/root. Up to three are pretty common at that.
The Mayo Clinic specialists explain that thicker hairs are usually the result of medication, treatment or hormonal issues.
