From: Hair growth-promoting effect of recombinant human sonic hedgehog proteins
Administration of Shh-N proteins increased not only the hair density but also the hair length in vivo. After depilation, the skin on the back was injected daily with the vehicle (PBS, black bar) or 5 μg/ml of Shh-N (gray bar). Photographed and measurement of the length of the hair in each animal were taken on days 7 and 14. Compared to the PBS-treated animal, Shh-N-treated mice showed higher hair density and longer hair
