• Becoming dry
• Brittle and cracked
• Inhibits growth of microorganism on the skin

However, the glands can overproduce sebum that can cause oily scalp. This is usually caused by factors like stress and DHT.

• Blood and lymph vessels
  The blood and lymph vessels are your energy and nutrient supply line to the skin and hair follicles. This supply will be disconnected from your hair follicle when it reaches the CATAGEN phase.
