Hair transplants have become a popular solution for individuals experiencing hair loss. The procedure involves taking hair follicles from one part of the body, typically the back of the scalp, and transplanting them to areas with thinning or no hair. Behind this seemingly straightforward process lies a complex interplay of biological factors.

Hair Follicle Anatomy

Understanding the biology of hair transplant london starts with delving into the anatomy of hair follicles. Hair follicles are small, tube-like structures in the skin that produce and regulate hair growth. The follicle contains various components, including the papilla, matrix cells, and sebaceous glands. The health and viability of these structures are crucial for successful hair transplantation.

Donor Dominance

One of the fundamental principles underlying hair transplants is the concept of “donor dominance.” Hair follicles from certain regions of the body, particularly the back and sides of the scalp, are genetically resistant to the hormone dihydrotestosterone (DHT), a major contributor to hair loss. When these resistant follicles are transplanted to areas affected by hair loss, they maintain their genetic resistance, continuing to grow despite the presence of DHT.

The Transplantation Process

Hair transplantation involves meticulous precision. Surgeons carefully extract individual follicular units, each containing one to four hairs, from the donor area. These units are then transplanted into tiny incisions made in the recipient area. The angle, depth, and density of these transplants are critical factors in achieving a natural-looking result.

Healing and Growth

Post-transplant, the body undergoes a healing process to integrate the transplanted follicles. Initially, the transplanted hairs may shed, but this is a normal part of the process. Over time, new hair growth emerges, and the transplanted hairs establish themselves in their new location. Patience is key, as it may take several months for the full results to become apparent.


The science of hair transplants is a fascinating blend of biology, precision surgery, and understanding genetic factors. As technology continues to advance, the field evolves, offering hope and effective solutions for individuals seeking to restore their hair and confidence.
