Did you know that researchers recommend scalp massage? They've discovered that regular scalp massage increases hair thickness by stretching the cells of hair follicle. This in turn stimulates the follicles to produce a thicker hair shaft. Scalp massage is also being investigated as an aid in dilating the capillary network beneath the skin that could encourage hair growth.
This is exciting - because for years, the only thing that reliably grew more hair was synthetic drugs. And actually what the current hair growth drugs do is to prolong the Anagen phase wherein hair grows before Catagen, or the transitory phase before the hair follicle rests, kick in. What this means to people on those drugs is that if they discontinue using them then all the hair in false Anagen stage enter Catagen at once and more hair loss is experienced. That's kind of a huge blow to the psyche, right? So scalp massage makes a great deal more sense in the scheme of things.
These massagers have soft silicone bristles that will massage your scalp without damaging hair.
