TLDR Preserving intact follicular units improves hair transplant success.
In 1984, Headington introduced the concept of the "Follicular Unit" in hair anatomy, which was a significant advancement in understanding hair growth. He discovered that hair grows in follicular units consisting of 1 to 4 hairs, each with its own neurovascular supply, sebaceous glands, sweat glands, and pilo-erectile muscle, all encased in a collagen sheath. This finding suggested that preserving these intact units during hair transplantation could enhance graft survival and promote better hair growth outcomes.
