Some of the alternative theories as to the cause of hair loss have espoused a relationship between the condition of the scalp, circulation, and even diet among many reasons. In the case of the health of the scalp noted scientist Loren Pickart has shown that purely by enhancing the scalp’s mantle with external treatments composed of copper peptides and components of blood you can once again rejuvenate the hair follicles into further production. Other researchers have also put fourth ample evidence that even with minor manipulation of the scalp’s blood flow with massage you can induce hair growth. One example of this is the laser brush, which emits low level light beams that encourage blood circulation to restore the hair. Plus remember this is an invention still in its infancy with likely improvements in the future.
