Hair transplant in Riyadh, like anywhere else, relies on established scientific principles to restore hair. Understanding these principles is crucial for anyone considering the procedure. Here's a breakdown of the science behind hair transplants:
1. The Role of DHT and Donor Dominance:
- Male pattern baldness, the most common cause of hair loss, is primarily driven by dihydrotestosterone (DHT), a hormone that shrinks hair follicles.
- The back and sides of the scalp, known as the donor area, are generally resistant to DHT's effects. This phenomenon, called "donor dominance," is the cornerstone of hair transplant success.
- Transplanted hair follicles retain their DHT resistance, meaning they will continue to grow even in areas affected by baldness.
2. Follicular Unit Extraction (FUE):
- FUE involves extracting individual follicular units, which are natural groupings of 1-4 hairs, directly from the donor area.
- A specialized micro punch tool is used to carefully remove each follicular unit, minimizing trauma to the scalp.
- FUE leaves tiny, circular scars that are virtually undetectable, especially with shorter hairstyles.
- This method is favored for its less invasive nature and faster recovery time.
3. Follicular Unit Transplantation (FUT):
- FUT involves removing a strip of scalp from the donor area.
- The strip is then dissected under a microscope to separate individual follicular units.
- These units are then transplanted into the recipient area.
- FUT leaves a linear scar, which can be concealed with longer hair.
- This method is more suitable for patients requiring a large number of grafts.
4. The Transplantation Process:
- Both FUE and FUT involve creating tiny incisions in the recipient area, where the follicular units will be placed.
- The surgeon carefully inserts each follicular unit into the incisions, ensuring proper angle and direction to mimic natural hair growth.
- The artistry of the surgeon is paramount in creating a natural-looking hairline and achieving optimal density.
- The grafts need to be kept moist and at the correct temperature to ensure survival.
5. Post-Operative Healing and Growth:
- After the transplantation, the scalp undergoes a healing process.
- Small scabs form around the transplanted grafts, which typically fall off within a week or two.
- "Shock loss," a temporary shedding of the transplanted hair, often occurs within the first few weeks. This is a normal part of the process.
- New hair growth begins around 3-4 months post-surgery.
- Full results are typically visible within 12-18 months.
6. Factors Affecting Success:
- Donor Hair Quality: The density and thickness of donor hair significantly impact the results.
- Surgeon's Expertise: A skilled surgeon with experience in hair transplant techniques is essential for optimal outcomes.
- Patient's Health: Overall health and adherence to post-operative care instructions play a crucial role in healing and growth.
- Riyadh's Climate: The hot, dry climate necessitates diligent hydration and sun protection to support healing.
7. Advancements in Technology:
- Robotic FUE systems enhance precision and efficiency in follicular unit extraction.
- Advanced microscopes allow for meticulous dissection of follicular units, improving graft survival rates.
- Platelet Rich Plasma (PRP) therapy can be used in conjunction with a hair transplant to enhance healing and hair growth.
By understanding the science behind hair transplants, patients in Riyadh can make informed decisions and achieve natural-looking, lasting results.
