TB4 Follicle Grow contains the naturally occurring peptide Thymosin Beta-4. TB4 is in the family of signaling peptides known to exist naturally in many body tissues. Recent medical discoveries have linked a deficiency of this signaling peptide to the genes of balding follicles in male pattern baldness. TB4 has been shown to grow hair on bald laboratory mice. The new theory is that improving availability of TB4 to the dormant follicles may, through the genetic pathway, enable them to renew the follicle growth stage just as properly functioning follicles do. TB4 has not yet been fully tested to prove human hair growth but it is being used successfully in human wound healing research. The pure protein like the one in your body is costly to manufacture, synthesized from 43 amino acids. Our product formulation protects the valuable peptide and includes ReJuviance trans-scalp technology to enhance its delivery to the hair follicles. There are more than 3 milligrams of the valuable TB4 peptide in each container. (Check the Internet cost for only 3 mg of the pure peptide, approaching $100.) The product formula does not contain preservatives that might degrade or damage the peptide. Although regulatory compliance prevents us from making any formal hair growth claims, this product dispenses easily, disappears quickly, smells good, and washes off easily with water. Can be applied morning and night. Excellent for all hair types and styles. Statements made about the benefits of our products have not been approved by the FDA.
