Hi sir, I have really good hair, a month back I shaved my head at home with a Philips one blade AGAINST THE GRAIN, from then I feel that some hair follicles are shortened and seems short compared to rest on hair, so it gives me an impression of less dense hair, as some hair are growing as normal, some are at the same stage even after a month, does shaving head against the grain minitiarize hair, and stop hair growth ?
