Why doesn’t grafted hair fall out?

Grafted Hair Fall Out

During a surgical hair transplant, healthy hair follicles are removed from one location and moved to another where they are no longer viable. “Graft” is the common word for a hair-bearing strip of skin. Grafts can be obtained from any part of the body, although the occipital scalp (located on the posterior scalp) is the most commonly used due to its high sustainability.

The shape and size of the graft are determined by technology, instruments, and surgical methods. Hair grafts are created by extracting tissue from the donor area. The goal is to take a little piece of hair-growing tissue and relocate it to a region of the scalp that cannot.

Follicular unit transplantation, often known as FUT, and individual unit extraction are two methods for removing the tissue holding hair from the donor site (Follicular Unit Extraction).

With FUT, stereoscopic dissecting microscopes are used to harvest the grafts from the donor strip. The follicular units are saved and prepared for implantation in the recipient’s scalp. The follicular unit usually has 2-3 hairs.

The medical professional makes scalp incisions that match the graft’s size. The grafts are then inserted one at a time into each implantation site, at the right length and orientation to match the surrounding hair.

FUE does not require the removal of a donor strip. Instead, each follicular unit is removed from the scalp separately. After that, the follicular cells are maintained and replanted into the scalp.

Graft survival

Graft survival refers to the ability of transplanted hair follicles (grafts) to survive and continue growing in their new location after a hair transplantation procedure. It is a crucial aspect of the overall success of the surgery and is influenced by various factors, including surgical technique, patient characteristics, and post-operative care. Here are some key points about graft survival:

  1. Surgical Technique: The skill and experience of the surgeon performing the hair transplantation procedure play a significant role in graft survival. Surgeons must carefully harvest, prepare, and implant the grafts to minimize trauma and damage to the follicles. Techniques such as follicular unit transplantation (FUT) or follicular unit extraction (FUE) may be used, with each having its advantages and considerations for graft survival.
  2. Graft Handling: Proper handling of the grafts during extraction, preparation, and implantation is critical for ensuring their survival. Grafts should be handled gently to minimize damage to the follicles and ensure they remain viable for transplantation.
  3. Recipient Site Preparation: Creating recipient sites in the scalp for graft placement requires precision to ensure optimal graft survival. The depth, angle, and orientation of the recipient sites must be carefully considered to facilitate proper blood supply and integration of the grafts into the surrounding tissue.
  4. Patient Factors: Patient characteristics, such as scalp laxity, skin quality, and hair characteristics, can influence graft survival. Additionally, underlying medical conditions, smoking, and certain medications may affect the healing process and graft survival rates.
  5. Post-Operative Care: Following the surgery, patients must adhere to specific post-operative care instructions provided by their surgeon. This may include avoiding activities that could dislodge or damage the grafts, following a prescribed skincare regimen, and taking medications as prescribed to promote healing and minimize the risk of infection.
  6. Monitoring and Follow-Up: Surgeons typically schedule follow-up appointments to monitor the progress of healing and assess graft survival. During these appointments, any issues or concerns can be addressed, and adjustments to the post-operative care plan can be made as needed to optimize graft survival and overall outcomes.

Overall, graft survival is influenced by multiple factors, and maximizing the survival rate requires meticulous surgical technique, proper patient selection, and diligent post-operative care. By addressing these factors, surgeons can enhance the likelihood of successful graft survival and achieve satisfactory results for their patients.

Grafted hair loss

Grafted Hair Fall Out

The transplanted follicles and associated hairs will remain in place for about 1-2 weeks following a hair transplant. During this time, the hair follicles start to enter a resting phase, which is followed by the onset of hair shedding. This shock loss might begin as soon as 10 days after transplantation. It may last up to a year.

At two weeks, you can detect some hair shedding in the grafted hairline. One month after surgery, the majority of the grafted hair has shed. There is very little redness in the operated region. This shedding of hair is normal and does not signify the scalp “rejecting” the transplanted hairs.

The hairs that had fallen out three months after the hair transplant are now beginning to come again. The patient may anticipate solid development over the upcoming months, with the outcome being clear within 8-12 months following therapy.

Hair restoration surgery allows for the recovery of hair from the region where it has been lost through the hair transplant method. The FUE or FUT method is used for hair transplantation.

Concerning hair transplantation, the sides and back of the scalp—which possess DHT-resistant hair roots—are the donor region of the scalp and are also known as the safest donor zone.

DHT, or Di-Hydro Testosterone, is a catalytic version of the androgen hormone found in scalp tissues. When the genetic and hormonal effects are combined, the Dihydro hormone is to blame for the hereditary cause of hair loss. Because of their loss sensitivity, Dihydro concentrations in scalp tissues eventually induce severe hair loss, shrinkage, and baldness.

However, hairs that dwell in the safe donor area of the scalp are particularly resistant to the effects of DHT and remain on the scalp indefinitely, even after being transplanted to another place on the scalp. The Dihydro resistance of the scalp region has high importance in the realm of hair restoration since it defines the long-term success of the surgery.

The safe donor zone of the scalp

The safe donor zone of the scalp, also known as the donor area, is a critical region in hair transplantation surgery. It refers to the area on the back and sides of the scalp where hair follicles are genetically resistant to the hormone dihydrotestosterone (DHT), which is primarily responsible for hair loss in individuals with androgenetic alopecia (pattern baldness).

Here are some key characteristics and considerations regarding the safe donor zone:

  1. Genetic Resistance: Hair follicles in the safe donor zone are inherently resistant to the effects of DHT, making them less susceptible to miniaturization and eventual hair loss. This genetic resistance ensures that the transplanted hair retains its ability to grow permanently in the recipient area.
  2. Stability and Permanence: Hair follicles harvested from the safe donor zone maintain their characteristics of thickness, color, texture, and growth pattern even after transplantation. This stability and permanence contribute to the long-term success of hair restoration procedures.
  3. Sufficient Hair Density: The safe donor zone typically has a higher hair density compared to other areas of the scalp affected by hair loss. This allows for the extraction of a sufficient number of hair follicles without causing noticeable thinning or balding in the donor area.
  4. Ideal Harvesting Area: Surgeons prefer to harvest hair follicles from the safe donor zone due to its reliability and minimal risk of follicle damage. The follicles can be extracted using techniques such as follicular unit extraction (FUE) or strip harvesting (FUT), depending on the patient’s needs and the surgeon’s preference.
  5. Natural Appearance: Hair follicles transplanted from the safe donor zone closely resemble the recipient’s natural hair, ensuring a seamless integration with the existing hair. This results in a natural-looking hairline and overall aesthetic outcome.
  6. Limited Donor Supply: While the safe donor zone provides a valuable source of hair follicles for transplantation, there is a finite supply of donor hair available. Surgeons must carefully plan the harvesting process to maximize the use of donor hair while preserving the donor area’s aesthetics.

In summary, the safe donor zone of the scalp plays a crucial role in hair transplantation surgery by providing a reliable source of genetically resistant hair follicles. Its characteristics of stability, permanence, and natural appearance contribute to the success and satisfaction of patients undergoing hair restoration procedures.

The role of the safe donor area in hair transplantation

The safe donor area plays a crucial role in hair transplantation as it serves as the source of hair follicles that will be transplanted to areas of hair loss or baldness on the scalp. This area, typically located at the back and sides of the scalp, is genetically resistant to hair loss and is therefore considered the most reliable source of donor hair.

Here are some key roles of the safe donor area in hair transplantation:

  1. Source of Healthy Hair Follicles: The safe donor area provides hair follicles that are genetically programmed to continue growing throughout a person’s lifetime. These follicles are not susceptible to the effects of dihydrotestosterone (DHT), the hormone responsible for hair miniaturization and balding in individuals with androgenetic alopecia.
  2. Natural Appearance: Hair follicles harvested from the safe donor area closely resemble the recipient’s natural hair in terms of texture, color, and growth pattern. This ensures a more natural-looking result after transplantation, as the transplanted hair blends seamlessly with the existing hair.
  3. Long-Term Sustainability: Since the hair follicles extracted from the safe donor area are resistant to hair loss, the transplanted hair typically continues to grow indefinitely in its new location. This provides long-term sustainability and permanent results for the patient.
  4. Minimal Risk of Hair Loss: By utilizing hair follicles from the safe donor area, hair transplant procedures minimize the risk of post-transplant hair loss. The transplanted hair maintains its resistance to DHT, reducing the likelihood of further hair loss in the treated areas.
  5. Versatility in Transplantation Techniques: The safe donor area allows for various transplantation techniques, such as follicular unit transplantation (FUT) and follicular unit extraction (FUE). These techniques offer flexibility in harvesting hair follicles, ensuring optimal results based on the patient’s specific needs and preferences.

Overall, the safe donor area is essential in hair transplantation as it provides a reliable source of healthy hair follicles that can restore natural-looking hair growth in areas affected by hair loss or baldness. Its role is fundamental in achieving successful and aesthetically pleasing outcomes for patients undergoing hair transplant procedures.

Why doesn’t transplanted hair fall out?

Transplanted hair doesn’t fall out because it is taken from areas of the scalp that are genetically resistant to hair loss, typically the back and sides of the head. These donor areas are not affected by hormones that contribute to male pattern baldness or other forms of hair loss. Therefore, when hair follicles are transplanted from these areas to areas experiencing hair loss, they maintain their genetic resistance to hair loss and continue to grow normally. Additionally, the surgical process of hair transplantation involves placing the hair follicles in a way that mimics natural hair growth patterns, ensuring their survival and longevity. As a result, transplanted hair typically continues to grow for the rest of the individual’s life.

Can you lower your risk of shedding following surgery?

Yes, there are steps you can take to lower the risk of shedding following surgery:

  1. Follow Post-Surgery Care Instructions: Adhere to your surgeon’s post-surgery instructions meticulously. This may include avoiding strenuous activities, following a specific diet, and taking prescribed medications.
  2. Maintain a Healthy Diet: Eating a balanced diet rich in vitamins and nutrients can support overall health, including hair health. Foods high in protein, vitamins A, C, and E, and minerals like zinc and iron can promote hair growth and strength.
  3. Stay Hydrated: Proper hydration is essential for overall health and can also benefit hair health. Drink plenty of water to keep your body hydrated.
  4. Avoid Stress: Stress can contribute to hair shedding, so try to manage stress levels through relaxation techniques, mindfulness, exercise, or therapy.
  5. Protect Your Hair: Avoid hairstyles that pull on the hair or cause tension on the scalp, as this can lead to shedding. Be gentle when brushing or styling your hair, and use heat styling tools sparingly.
  6. Limit Chemical Treatments: Minimize the use of harsh chemicals such as hair dyes, relaxers, and perms, as they can weaken the hair and contribute to shedding.
  7. Use Gentle Hair Care Products: Choose shampoos, conditioners, and styling products that are gentle on the scalp and hair. Look for products specifically designed for your hair type and avoid those containing harsh chemicals.
  8. Consult a Dermatologist: If you experience excessive shedding or notice changes in your hair after surgery, consult a dermatologist or healthcare professional for personalized advice and treatment options.

By taking these steps, you can help reduce the risk of shedding following surgery and support healthy hair growth and maintenance.
