Hair transplant
A hair transplant is a surgical procedure in which hair follicles are moved from one part of the scalp to another. The topic comes up often and the information about it is uneven, partly because it is most often discussed in an advertising context. This text is an informative overview: what the procedure is, how it is performed and what limits it.
The basic principle
The procedure rests on the concept of donor dominance. In most people the follicles at the back and sides of the head are not sensitive to dihydrotestosterone, the hormone that causes follicle miniaturisation in hereditary thinning. When such a follicle is moved into an area that is thinning, it keeps its original properties and continues to grow.
From that follows the basic limitation: a transplant does not create new follicles. It redistributes existing ones. The total number of hairs on the head stays the same; only their arrangement changes.
Two basic techniques
FUT, follicular unit transplantation by strip
A strip of skin with follicles is surgically removed from the back of the head and the incision is sutured. Under a microscope the strip is divided into individual follicular units, which are then implanted into the recipient area. The method allows a large number of grafts in a single session, but leaves a linear scar at the back of the head, visible with very short haircuts.
FUE, follicular unit extraction
Follicular units are extracted one by one with micropunches under one millimetre in diameter. Instead of a linear scar, small dot-like marks remain, which are as a rule less noticeable. The procedure takes longer and requires more experience from the operator. FUE is the most common technique today, with a range of variants differing in instruments and implantation method.
How the procedure goes
- Consultation and planning, assessment of the type and stage of thinning, the density of the donor area, design of the new hairline.
- Preparation, trimming the donor area and local anaesthesia.
- Graft extraction, several hours of work, depending on the number of units.
- Creating channels and implanting, angle, direction and arrangement determine how natural the result will look.
- Recovery, redness and crusting in the first days, with instructions on washing and rest.
Shock phase and timeline
It is expected that transplanted hairs will fall out in the first weeks after the procedure. The follicle stays in the skin and enters a resting phase. New growth usually begins around the third or fourth month, while the final result is only assessed after twelve to eighteen months. This timeline surprises many who expect a quick outcome.
Limits that are discussed less often
The donor area is a finite resource. With pronounced thinning there are often not enough grafts to cover the whole affected surface, so planning comes down to priorities, most often the front third, which contributes most to the impression of framing the face.
The procedure also does not stop the process that led to the thinning. If androgenetic alopecia progresses, untransplanted hair around the treated area can continue to thin, which over time produces an unnatural arrangement. That is why planning in younger people is considered particularly delicate, because it is hard to predict how far the process will go.
Not all types of hair loss are suitable for transplantation either. In scarring alopecias and active inflammatory processes on the scalp the procedure is as a rule not indicated until the condition stabilises, and sometimes not even then. Assessing suitability is purely a medical matter.
Risks
Like any surgical procedure, a transplant carries risks: infection, bleeding, swelling, temporary loss of sensation, folliculitis, cyst formation, uneven density, a visible scar and an aesthetically unsatisfactory result. A badly placed hairline or a wrong implantation angle are difficult to correct.
Medical tourism
Hair transplantation is an area where cross-border treatment is very widespread and prices differ enormously. The questions that specialist sources list as key when choosing: who exactly performs the procedure and what their qualification is, how many patients are operated on the same day, how follow-up after returning home is organised and how a possible complication is dealt with. A low price often means that most of the work is done by technical staff, with brief contact with a doctor.
What this text does not claim
A transplant is a medical procedure and is assessed exclusively in conversation with a specialist. Cosmetic hair and scalp care products belong to another category: they do not treat, do not replace surgery and are not compared with it. Scalp care before or after the procedure is carried out exclusively according to the instructions of the doctor who performed it, because the skin is in a particular state during that period.
In short
- A transplant moves existing follicles; it does not create new ones.
- The two main techniques are FUT and FUE, with different marks and workflow.
- Transplanted hairs fall out in the first weeks; the final result is seen after a year or more.
- The donor area is limited, and the underlying thinning process is not stopped by the procedure.
- Not all forms of hair loss are suitable for the procedure.
- Assessment, indication and aftercare belong to the doctor.
