Does shaving the scalp stimulate hair growth?
This again has no basis at all. In a 1970 issue of the Journal of Investigative Dermatology, an article entitled Shaving and Hair Growth reported that two doctors, Y.lo Lynfield and P. MacWilliams, have actually studied the effects of shaving by getting volunteers to shave only one leg regularly, and have observed no difference in the weight of hair produced, the thickness (diameter) of hair or the rate of growth between the shaven and unshaven sides.
