Hair transplantation is a surgical procedure that restores hair to areas with permanent hair loss using the patient's own hair follicles. It is most commonly performed for androgenetic alopecia (male pattern baldness), but it may also be suitable for some women, as well as individuals with hair loss caused by trauma or certain medical conditions.

How the procedure works

• Consultation and planning: The surgeon evaluates your pattern of hair loss, the quality and density of the donor area (usually the back of the scalp), your overall health, and your expectations.
• Harvesting hair follicles: The most commonly used technique today is FUE (Follicular Unit Extraction), in which individual hair follicles are carefully removed from the donor area.
• Implantation: The harvested follicles are implanted into the thinning or bald areas while preserving the natural direction and angle of hair growth.
• Recovery: Mild swelling, redness, and scabbing are common during the first few days. The scabs typically fall off within one to two weeks.

Common techniques

• FUE (Follicular Unit Extraction): The most widely used method. It leaves tiny, barely visible scars and generally offers a relatively quick recovery.
• DHI (Direct Hair Implantation): Hair follicles are implanted directly using a specialized implantation pen. In selected cases, it may allow for denser implantation or reduce the need for shaving, although it is not necessarily superior to FUE in every situation.
• FUT (Follicular Unit Transplantation): A strip of scalp is removed from the donor area to harvest hair follicles. This technique is used less frequently today because it leaves a linear scar.

Who is a good candidate?

Suitable candidates generally have:

• A stable pattern of hair loss.
• Adequate donor hair in the back or sides of the scalp.
• Good overall health.
• Realistic expectations about the results.

When will you see the results?

• During the first 2–8 weeks, many of the transplanted hairs may shed. This is known as shock loss and is a normal part of the healing process.
• New hair growth usually begins around 3–4 months after the procedure.
• Noticeable improvement is typically seen between 6 and 9 months.
• Final results are usually evaluated after 12–18 months.

Risks and possible complications

As with any surgical procedure, hair transplantation carries some risks, including:

• Infection (rare)
• Bleeding
• Swelling
• Temporary numbness
• An unnatural-looking hairline if the procedure is poorly planned
• Lower-than-expected hair density or the need for an additional session

Factors that influence success

The outcome depends on several factors, including:

• The quality and density of the donor area
• The surgeon's experience and skill
• Proper hairline design
• Following post-operative care instructions
• The progression of the patient's underlying hair loss

In some cases, doctors may also recommend medical treatments such as minoxidil or finasteride to help preserve existing hair and improve long-term results.
