Factors Affecting the Growth and Survival of Follicular Grafts

Follicular grafting, commonly referred to as hair transplantation, involves the meticulous relocation of hair follicles from a donor site to a recipient site, typically to address hair loss. The success of this procedure is contingent on a variety of factors that influence the growth and survival of the transplanted follicles. Understanding these factors is crucial for improving outcomes and achieving natural-looking results.

1. Donor Site Quality

A. Density of Hair Follicles

  • High Density: More follicles can be harvested without significantly impacting the appearance of the donor site.
  • Low Density: Limited follicle availability can affect the overall success and coverage of the transplant.

B. Hair Characteristics

  • Thickness and Texture: Thicker and coarser hair provides better coverage and can influence the perceived density of the transplanted area.
  • Color: Darker hair contrasts more with the scalp, affecting visual density.

2. Extraction Technique

A. Follicular Unit Transplantation (FUT)

  • Involves removing a strip of scalp and dissecting it into individual follicular units.
  • Pros: Higher yield of viable grafts.
  • Cons: Linear scar, longer recovery time.

B. Follicular Unit Extraction (FUE)

  • Individual follicles are extracted directly from the donor area.
  • Pros: Minimally invasive, no linear scar.
  • Cons: Potential for higher follicle transection rate.

3. Handling and Storage of Grafts

A. Temperature Control

  • Grafts must be kept at an optimal temperature (typically around 4°C) to prevent desiccation and ensure viability.

B. Hydration

  • Maintaining proper hydration of grafts is crucial to prevent drying out, which can significantly reduce survival rates.

4. Recipient Site Preparation

A. Incision Size and Depth

  • Precise control over the size and depth of recipient site incisions is necessary to avoid damage to existing hair and to ensure the grafts are placed at the correct angle and depth.

B. Blood Supply

  • Adequate blood flow to the recipient site is vital for providing nutrients and oxygen to the transplanted follicles, promoting growth and survival.

5. Post-Operative Care

A. Medication

  • Antibiotics: To prevent infection.
  • Anti-inflammatory drugs: To reduce swelling and improve healing.

B. Lifestyle Modifications

  • Avoiding activities that might dislodge grafts, such as strenuous exercise or wearing tight hats, is important during the initial healing period.

6. Patient Factors

A. Age and Health

  • Younger, healthier patients typically experience better outcomes due to more robust healing responses.

B. Smoking and Alcohol Use

  • Both smoking and excessive alcohol consumption can impair blood circulation and healing, negatively affecting graft survival.

7. Surgeon’s Expertise

A. Skill and Experience

  • The surgeon’s proficiency in both extraction and implantation techniques plays a critical role in the success of the transplant.

B. Artistic Ability

  • The ability to create a natural-looking hairline and achieve proper hair density requires an artistic touch, ensuring the results blend seamlessly with the patient’s existing hair.


The growth and survival of follicular grafts are influenced by a multitude of factors, ranging from the quality of the donor site and the techniques used in graft extraction and implantation, to post-operative care and the patient’s overall health. By understanding and optimizing these factors, both patients and practitioners can significantly enhance the success rates and aesthetic outcomes of hair transplantation procedures.
