Hair transplant surgery restores hair density using advanced FUE and DHI techniques. Learn about the procedure, diagnosis of hair loss, and recovery process.

Overview and definition

Hair transplantation is a microsurgical procedure that involves moving hair follicles from a part of the body known as the “donor site,” typically the back and sides of the scalp where hair is genetically resistant to balding to a “recipient site” that is balding or thinning. It is currently the only permanent solution for hair loss caused by androgenetic alopecia (pattern baldness). While traditionally associated with treating male pattern baldness, the field has expanded significantly to include hair restoration for women, as well as eyebrow, beard, and mustache transplants.

The Anatomy of the Hair Follicle

HAIR TRANSPLANT
  • The Graft: In the context of surgery, a follicular unit is called a “graft.” A single graft can contain anywhere from 1 to 4 individual hair strands.
  • The Bulb: The root of the hair, located deep in the dermis, which contains the living cells responsible for hair growth.
  • DHT Resistance: The crucial scientific principle behind hair transplantation is “Donor Dominance.” Hair follicles from the back of the head (the occipital region) are genetically resistant to Dihydrotestosterone (DHT), the hormone responsible for causing hair loss. When these follicles are moved to the front or top of the head, they retain this genetic resistance and continue to grow for a lifetime, even in their new location.

Evolution of Techniques: From Plugs to Precision

HAIR TRANSPLANT
  • FUE (Follicular Unit Extraction): The modern gold standard. Individual follicular units are extracted one by one from the donor area using a specialized microsurgical punch (less than 1mm in diameter). This method leaves no linear scar, heals quickly, and allows harvesting grafts without scalpel incisions.
  • DHI (Direct Hair Implantation): A modification of the FUE technique. In DHI, the extraction phase is similar, but the implantation involves using a specialized tool called a generic Choi Implant Pen. This allows the surgeon to implant the graft directly into the scalp without pre-creating holes (channels), offering precise control over the angle, depth, and direction of the hair.

Scope of Application

Hair transplantation is not limited to the scalp. The principles of FUE are applied to various areas:

  • Scalp Restoration: For male- and female-pattern baldness.
  • Facial Hair Transplants: Beard and mustache restoration for men with patchy growth or scarring.
  • Eyebrow Transplants: Restoring density to eyebrows lost due to over-plucking, genetics, or alopecia.

Scar Revision: Hiding scars from accidents or previous surgeries (like facelifts) by planting hair into the scar tissue.

Symptoms and Causes

While a hair transplant is a treatment, it is a response to a specific medical condition: alopecia (hair loss). Understanding the symptoms and underlying causes of hair loss is essential for determining if a patient is a suitable candidate for surgery. Not all hair loss is treatable with a transplant; therefore, recognizing the type of hair loss is the first step in the patient’s journey.

Symptoms and Patterns of Hair Loss

Hair loss manifests differently depending on the underlying cause and the patient’s gender. It is rarely a sudden event but rather a progressive process.

  • Receding Hairline: The most common early sign in men. The hairline begins to move backward from the forehead, often forming an “M” shape (receding at the temples).
  • Vertex Thinning: Loss of hair at the crown (top) of the head. This may start as a small bald spot that gradually expands outward.
  • Diffuse Thinning: Common in women (Ludwig pattern). Instead of a receding hairline, the part line on the top of the head becomes wider, and the overall density decreases across the entire scalp.
  • Miniaturization: Before hair falls out completely, it often undergoes a process in which individual hairs become thinner, shorter, and more brittle (wispy). This is a key indicator of androgenetic alopecia.
  • Excessive Shedding: Finding large amounts of hair on the pillow, in the shower drain, or on a hairbrush. While losing 50–100 hairs a day is normal, losing significantly more suggests an active shedding phase (telogen effluvium).
  • Patchy Loss: Coin-sized, smooth, round bald patches. This is characteristic of Alopecia Areata, an autoimmune condition.
  • Scarring: If the scalp looks shiny, smooth, and lacks visible follicle openings, it may indicate Cicatricial (Scarring) Alopecia, where inflammation destroys the follicle permanently.

Underlying Causes

Identifying the cause is critical because hair transplantation is primarily effective for genetic hair loss, whereas other causes may require medical therapy first.

  • Androgenetic Alopecia (Genetic Hair Loss): This is the cause of over 95% of hair loss in men and a significant percentage in women. It is a hereditary condition related to aging and hormones.
    • Mechanism: Testosterone is converted into Dihydrotestosterone (DHT) by an enzyme (5-alpha reductase). In susceptible individuals, DHT binds to receptors in the hair follicles, causing them to shrink (miniaturize) and eventually stop producing visible hair.
  • Hormonal Changes:
    • Pregnancy and Childbirth: Postpartum hair loss is common due to dropping estrogen levels.
    • Menopause: Hormonal shifts can trigger thinning in women.
    • Thyroid Issues: Both hypothyroidism and hyperthyroidism can cause diffuse hair loss.
  • Stress and Trauma (Telogen Effluvium): Severe physical or emotional stress (surgery, illness, drastic weight loss, grief) can push hair follicles prematurely into the resting phase (telogen). This results in shedding months after the event.
  • Medical Conditions and Medications:
    • Autoimmune diseases (Lupus, Alopecia Areata).
    • Scalp infections (Ringworm).
    • Drugs are used for cancer, arthritis, depression, and heart problems.
  • Traction Alopecia: Hair loss caused by tight hairstyles (braids, ponytails) pulling on the hair over time. This is a mechanical cause of damage to the follicle.

Diagnosis and Staging

A successful hair transplant begins with accurate planning. This requires a formal diagnosis to rule out non-permanent causes of hair loss and a “staging” process to calculate the exact number of grafts needed for coverage. At Liv Hospital, this evaluation is scientific and mathematical, ensuring that the donor area is not over-harvested and the recipient area receives adequate density.

HAIR TRANSPLANT

The Diagnostic Evaluation

Before any surgery is scheduled, the physician must confirm that the hair loss is stable and the donor area is healthy.

  • Trichoscopy (Digital Microscopic Analysis): A specialized handheld microscope is used to examine the scalp. It helps the doctor see:
    • Follicular Density: How many hairs are present per square centimeter in the donor zone?
    • Hair Shaft Diameter: The thickness of the hair (thicker hair provides better coverage).
    • Miniaturization Rate: The percentage of hairs that are shrinking.
  • Pull Test: A simple physical test where the doctor gently pulls on a cluster of hairs to see how many come out. This helps determine if the hair loss is currently active (shedding phase).

Blood Work: To rule out underlying metabolic issues. Tests often include Ferritin (iron storage), Thyroid Stimulating Hormone (TSH), Vitamin D levels, and hormonal panels for women (androgens, testosterone).

Staging Hair Loss: The Norwood and Ludwig Scales

Staging is the roadmap for the surgery. It allows the surgeon to communicate the extent of baldness and estimate the number of grafts required.

  • The Norwood-Hamilton Scale (For Men): This is the standard classification system for male pattern baldness.
    • Stage 1: No significant hair loss.
    • Stage 2: Mild recession of the hairline at the temples.
    • Stage 3: First stage of balding; deep recession at the temples (M-shape) or a spot on the vertex.
    • Stage 4-5: More extensive loss with a “bridge” of hair separating the front recession from the bald vertex.
    • Stage 6-7: The bridge of hair disappears, leaving a large horseshoe-shaped bald area. This stage requires the most grafts (often 4,000+).
  • The Ludwig Scale (For Women):
    • Grade I: Mild thinning on the top of the head; the frontal hairline remains intact.
    • Grade II: Moderate thinning; the scalp becomes clearly visible through the hair.
    • Grade III: Severe thinning; very little hair remains on the crown.

Graft Calculation and Donor Management

HAIR TRANSPLANT

One of the most critical parts of the diagnosis is assessing the Donor Capacity.

  • Finite Resource: The donor area (back of the head) is not infinite. A typical person has about 6,000 to 8,000 grafts available for lifetime harvesting.
  • Coverage Strategy: The surgeon calculates the bald spot’s surface area (in cm²) and multiplies it by the desired density (e.g., 40–60 grafts per cm²) to determine the session size.

Treatment Details

HAIR TRANSPLANT

Hair transplant surgery is a meticulous, multi-step process that combines medical precision with artistic design. It is typically an outpatient procedure performed under local anesthesia, lasting anywhere from 6 to 8 hours, depending on the number of grafts. The goal is to achieve a result that looks completely natural and lasts a lifetime.

You can contact us today to start your evaluation, book a free certified online doctor consultation or send your medical reports for review.

Pre-Procedure Planning and Anesthesia

  • Hairline Design: This is the artistic phase. The surgeon draws the new hairline on the patient’s forehead. The design must adhere to the “Rule of Thirds” for facial symmetry and consider the patient’s age. A hairline that is too low or too straight will look unnatural.
  • Local Anesthesia: The patient remains awake but feels no pain. The scalp is numbed using local anesthetic injections.
  • Needle-Free Injection (Jet Injection): For patients with a fear of needles, high-pressure devices can deliver the anesthetic through the skin without a needle prick, increasing comfort.

Step 1: Extraction (Harvesting)

The first medical phase involves removing the hair from the donor zone.

  • Micromotor FUE: The surgeon uses a low-speed, high-torque micromotor equipped with a tiny punch (0.6-0.9mm). The punch isolates the follicular unit, which is then gently extracted with forceps.
  • Preservation: Once extracted, the grafts are incredibly fragile. They are placed in a chilled, nutrient-rich storage solution (like Hypothermosol) to keep the cells alive and prevent dehydration while they await implantation.

Step 2: Channel Opening (The Incision Phase)

Note: In DHI, this step is combined with Step 3. For standard FUE, the surgeon creates tiny incisions in the recipient area where the grafts will be placed.

  • Sapphire Blades: At Liv Hospital, we prioritize sapphire-crystal blades over standard steel. Sapphire blades hold a sharper edge, creating smoother, cleaner channels. This reduces tissue trauma, minimizes bleeding (crusting), and allows for “dense packing” (placing hairs closer together).
  • Direction and Angle: The surgeon must follow the patient’s native hair’s natural growth pattern. For example, creating a “whirl” pattern at the crown or angling hairs forward at the hairline.

Step 3: Implantation (The Placement Phase)

  • Forceps Placement (FUE): Technicians gently insert the grafts into the pre-made Sapphire channels using micro-forceps.
  • DHI (Direct Hair Implantation): In this technique, the graft is loaded into a hollow needle known as a Choi Implanter Pen. The pen punctures the skin and injects the graft.
    • Advantages of DHI: It eliminates the need to shave the recipient area (unshaven transplant), reduces the time the graft spends outside the body, and allows for very high-density implantation between existing hairs.

Post-Operative Recovery and Adjunct Therapies

The success of a transplant relies heavily on the first 10 days of recovery.

  • The First Wash: Performed at the clinic 24-48 hours after surgery to teach the patient how to gently clean the scabs.
  • Shedding Phase (Shock Loss): Between weeks 2 and 6, the transplanted hairs will fall out. This is normal and expected. The root remains alive under the skin.
  • Regrowth Timeline: New growth begins around month 3 or 4. Significant visual improvement is seen by month 6, with the full result taking 12 to 18 months to mature.
  • Supportive Therapies:
    • PRP (Platelet-Rich Plasma): The patient’s blood is spun to concentrate growth factors, which are injected into the scalp to speed up healing and stimulate follicle activity.
    • Mesotherapy: Vitamin and mineral cocktails are injected into the scalp to nourish the grafts.

The Medical Center

Hair transplantation is often marketed as a cosmetic commodity, but it is, fundamentally, a surgical procedure that carries medical risks and requires strict sterility. Liv Hospital distinguishes itself by performing hair restoration within a JCI-accredited, full-service hospital environment, ensuring safety standards that small clinics cannot match. We combine this medical rigor with high-end aesthetic artistry.

Why Choose Liv Hospital for Hair Restoration?

The market is flooded with low-cost options, but the “Liv Standard” prioritizes quality, safety, and longevity over mass production.

  • Doctor-Led Procedures: Unlike many clinics where technicians perform the entire surgery, at Liv Hospital, expert physicians oversee the operation, particularly the critical stages of planning and channel opening.
  • Hospital-Grade Sterility: Performing surgery in a general hospital environment minimizes the risk of infection (necrosis) and ensures that emergency medical infrastructure is available if needed.
  • Corrective Surgery Experts: A significant portion of our practice involves fixing “botched” transplants from other clinics, repairing unnatural hairlines, over-harvested donor zones, and poor density. We strive to get it right the first time.

Advanced Technology and Techniques

We utilize the latest globally recognized technologies to maximize graft survival rates (the percentage of transplanted hairs that grow).

  • Sapphire FUE and DHI Specialization: We do not use outdated steel blades. Our standard of care involves Sapphire FUE for maximum density and DHI for precision in unshaven cases or for long hair.
  • Soft Anesthesia (Sedation): For maximum patient comfort, our anesthesiology department can provide mild sedation, helping the patient sleep through local anesthesia injections and making the procedure virtually painless.
  • Computer-Assisted Analysis: We use digital analysis tools to measure the exact surface area of the transplant zone and the donor zone density, eliminating guesswork from the graft estimation process.

A Holistic Approach to Hair Health

We view hair transplantation as one part of a broader hair health strategy.

  • Post-Op Follow-Up: We follow our patients for a full year. Our team reviews progress photos at months 1, 3, 6, and 12 to ensure growth is on track.
  • Stem Cell and Regenerative Therapies: Beyond standard PRP, we offer advanced regenerative options (such as autologous tissue suspension) to support the donor area and strengthen existing native hair, preventing future loss.

At Liv Hospital, we restore more than just hair; we regain self-confidence. Our commitment is to deliver results that are undetectable, natural, and permanent.

FREQUENTLY ASKED QUESTIONS

How does a hair transplant actually work?

Hair transplantation operates on the scientific principle of “Donor Dominance.” Hair follicles from the back of the head (the donor area) are genetically resistant to DHT, the hormone that causes balding. When these healthy follicles are moved to a balding area (the recipient site), they retain this genetic resistance and continue to grow for a lifetime, just as they would have in their original location.

What is the difference between FUE and DHI?

Both techniques involve extracting grafts individually (FUE), but the implantation method differs:

  • FUE (Follicular Unit Extraction): The surgeon first creates tiny incisions (channels) in the recipient area, and then technicians place the grafts into these holes using forceps.
  • DHI (Direct Hair Implantation): Uses a specialized tool called a Choi Implanter Pen. The graft is loaded into the pen, which punctures the skin and implants the hair. This allows for precise control of angle and depth and is often used for unshaven transplants.
Is the procedure painful?

Hair transplantation is performed under local anesthesia, so the patient feels no pain during the surgery. At Liv Hospital, we use Needle-Free (Jet) Injection technology to numb the scalp without the initial prick of a needle. For patients with high anxiety, mild sedation is also available to ensure the experience is comfortable.

What is "Sapphire FUE" and why is it better than standard FUE?

Standard FUE uses steel blades to open channels in the scalp. Sapphire FUE uses blades made from sapphire gemstones. These blades are sharper and V-shaped, allowing the surgeon to create smaller, smoother microchannels. This results in:

  • Less tissue trauma and bleeding.
  • Faster healing (less scabbing).
  • Higher density (hairs can be packed closer together).
How long does it take to see the final results?

Patience is key. New growth typically begins around month 3 or 4. You will see significant visual improvement by month 6, but the full, mature result with complete density and texture takes 12 to 18 months to develop.
