The inner root sheath in hair follicles plays a key role in hair growth and health.
July 1998 in “Dermatologic Surgery” Various techniques and tools for hair restoration were presented in 1998, including a mathematical model for donor area, use of lasers in surgery, methods for controlling grafted hair direction, and ways to increase graft yield. Satisfaction rates were around 39%, and studies showed trauma and dehydration can damage hair follicles.
