Studies suggest that sulfur benefits the hair in numerous ways. The Cellular Matrix Study has been conducting tests on the effects of sulfur since 1999. Its findings reveal numerous health advantages of taking sulfur supplements. Of the 1,100 participants to date, the majority have reported multiple benefits, one of which is a healthier head of hair. Further, people with white or graying hair reported a return to their natural hair color. This result indicates regenerated pigment glands existing at the base of the hair follicle. A reversal in hair loss is also evident in these studies, suggesting that sulfur not only plays an important role in replenishing hair loss, but it also may prevent it.
