An aging scalp becomes thinner and loses much of its elasticity. The number of blood vessels in the dermis reduces. There are fewer hair follicles and often the hair loses its colour. All of this results in hair thinning and baldness.
The scalp ages 12 times faster than body skin and 6 times faster than facial skin.
Factors that contribute to scalp aging include
Reduced collagen levels
Poor blood circulation
Insufficient nutrition supply
Weakness of the liver and kidney (according to Traditional Chinese Medicine)
