Modern Techniques in Hair Transplantation
Published in Rubina Alves, Ramon Grimalt, Techniques in the Evaluation and Management of Hair Diseases, 2021
Once you have decided that a patient is a suitable candidate then develop a surgical plan which often is a series of procedures either over the short term or over a patient's lifetime as they lose more hair. The most important aspect to convey to the patient is that hair transplantation in its current format is simply reorganizing hair and not producing extra hair so, in other words, the permanent hair is limited. This means that the effect in the recipient area is also limited. If there is a big discrepancy between donor and recipient areas, then it may be wise not to proceed with surgery at all. It is important to distinguish between hair density which is the number of hairs/cm2 and the follicular unit density which is the number of FU/cm2. When communicating with patients, state whether you are discussing numbers of grafts or number of hairs as these are quite different amounts.
Hair and nail disorders

Hair transplantation utilizes hairs from the occipital scalp, which are harvested and reimplanted in other areas. The best results are achieved with transplantation of single or small numbers of follicular units, but typically 2000–3000 units have to be transplanted to achieve a reasonable outcome.
Disorders of hair and nails

In women, the use of an anti-androgen–prostagen combination (cyproterone acetate and ethinylestradiol – Dianette®) has been tried and some reduction in the rate of hair loss claimed. The antihypertensive vasodilator minoxidil has also been used topically, as increased hair growth was noted as a side effect from its oral use. Although the drug may increase hair growth in 20–30 per cent of patients, the hair is lost again when treatment stops, and the extent to which hair regrowth occurs is modest. Finasteride is contraindicated in women at risk of pregnancy – because it would cause feminization of a male fetus and variable results have been reported from studies in which it has been given to women with androgenetic alopecia. Hair transplantation utilizes hairs from the occipital scalp which are harvested and reimplanted in other areas.

Although increasingly popular amongst patients seeking treatment for hair loss, hair transplantation is not an appropriate option for all candidates. The correct selection of patients for hair transplant is an essential part of the procedure’s success, with important ethical and even legal implications (6,7). Physicians should ensure that patients have realistic expectations regarding results, and must inform patients of possible complications, eliciting written informed consent before the procedure. While the role of hair restoration surgery as a successful treatment for patients with androgenetic alopecia has been confirmed by multiple studies (8,9), patients with forms of primary cicatricial alopecia have traditionally been considered as poor candidates for hair transplantation. However, several case reports of successful hair transplant in patients with these conditions (10–13) and advances in surgical technique and physician expertise support consideration of these patients for hair transplant on a case-by-case basis, after ruling out the presence of inflammatory activity.
The pros and cons of follicular unit extraction (FUE) versus elliptical donor harvesting (FUT)
Published in Journal of Cosmetic and Laser Therapy, 2022
Starting in the 1960s and occurring well into the 1990s, the standard of hair transplantation was to use 10–25 hair per 3–4 mm grafts (1). However, with advances in technology and surgical technique, hair transplantation has evolved to exclusively utilizing 1–4 hair follicular units in the past 25 years (1,2). There are two donor harvesting techniques that are the standard for donor extraction of transplanted hair: elliptical donor harvesting (FUT) and follicular unit extraction (FUE) (2). FUT has been performed for longer and is a standard cutaneous ellipse from the posterior scalp and is dissected into follicular units by surgical assistants (2). FUE involves manual, device assisted, or robotic .8 mm-1.2 mm punches harvesting of individual follicular units (2). Although both techniques are considered the gold standard of treatment in hair transplantation, there are associated benefits and cons to both techniques, which leads to debate on which technique is superior (2). Considering that hair transplantation has produced natural-looking results in both genders for many years, and that hair loss has a markedly negative impact on quality of life for a patient, there are more patients now than ever seeking to treat hair loss through these techniques (3). This review will examine the pros and cons of both FUE and FUT(Table 1).

Established therapies for AGA include oral finasteride, low-level laser light therapy (LLLLT), and topical minoxidil. These modalities are ineffective for many patients, and include serious side effects including decreased libido, erectile dysfunction, impaired hepatic function, testicular pain, or contact dermatitis (10,11). Hair transplantation is an effective, but cost-prohibitive surgical approach for which not all patients are surgical candidates (12). Low-level laser therapy has been utilized in recent years to some success that is theorized to be attributed to increased circulation to the hair follicular unit (13). Platelet-rich plasma (PRP) is a novel treatment that has shown promise in treating AGA since research began only one decade ago. This study will explore the current state of research on PRP as a treatment for AGA.
