Stanford University scientists have made an important discovery that can help in dealing with hair loss.
They have found a key signaling molecule – laminins 511 – that instructs hair follicles to begin the hair-growing cycle.
The molecule transfers proteins between the outer and inner layers of skin, an exchange that causes hair formation.
Unlike Rogaine or Propecia which slow hair loss, the laminin-511 could potentially regenerate the actual follicles that grow hair.
The study was conducted in mice. Laminin-511 made hair grow during an embryonic stage of development.
Researchers hope it might work later in life as well. If using the molecule to trigger hair growth works after birth, it would be easy to use it as a drug that could be injected directly into the area where more hair is wanted.
The study is published in the Journal of Genes & Development.
