Using Nonscalp Hair in Scalp Hair Restoration-Theory and Execution

Harvesting of beard and body hair follicles for transplantation can be an effective form of treatment for appropriate patients. These patients may have had prior scalp transplantation and require repair but do not have sufficient scalp donor follicles remaining. Other patients will have these hairs mixed with scalp hairs to produce a greater density of hair on the bald scalp. Follicular unit excision (FUE) is preferred for body and beard follicle harvesting. Not all body hair is suitable for transplantation. Only hairs that are similar in appearance and behavior to scalp hair are suitable for transplantation to the scalp. The best nonscalp sources are the beard and anterior torso. Hairs from other body sites may be used for transplantation to the eyebrows. The standard techniques of FUE harvesting and anesthesia must be modified from those used in scalp harvesting to be safe and effective. With proper patient selection and technique, a significant cosmetic benefit can be achieved from these procedures.

Large-Scale Beard Extraction Enhances the Cosmetic Results of Scalp Hair Restoration in Advanced Androgenetic Alopecia in East Asian Men: A Retrospective Study

INTRODUCTION

Beard hair serves as an important additional donor supply to support hair transplantation in hirsute patients with extensive alopecia and lacking sufficient occipital hair. However, the efficacy and safety of large-scale beard hair extraction have not been studied extensively in the East Asian population.

METHODS

Data obtained from hirsute patients with extensive alopecia who underwent hair transplantation between March 2017 and December 2018 at Nanfang Hospital were analyzed. Occipital and beard hair were evaluated separately during the pre-, intra-, and post-operative periods. Individual beard hair follicular units (FUs) were harvested under tumescence using a hollow punch with an outer diameter of 0.8-0.9 mm. Follow-up examinations were scheduled at 3-5 days, 1 month, and 9 months postoperatively to check for complications, determine the survival rate of mixed, transplanted FU grafts, and assess patient satisfaction. Data were collected and analyzed statistically.

RESULTS

A total of 36 hirsute, male patients with advanced androgenetic alopecia (AGA) (Norwood-Hamilton V-VI) were included in this study. The density of the occipital and beard areas was 78.6 ± 4.6 and 48.4 ± 9.3 FU, respectively. It took 3.1 ± 0.9 h to harvest 3135 ± 863 FUs from the occipital area and 2.1 ± 0.6 h to harvest 2352 ± 599 FUs from the beard area. The transection rate for occipital FUs and beard FUs was 3.7 ± 0.4 and 3.9 ± 0.2%, respectively. Completion of the operation took approximately 10.0 ± 0.9 h, and no serious complications were reported 5 days after the procedure. An FU survival rate of 95.7 ± 1.6% was observed at 9 months after transplantation, with no visible hypopigmented scars observed in the bare areas. All patients were satisfied with the resulting cosmetic appearance.

CONCLUSION

Large-scale beard extraction, when combined with occipital hair extraction, is a safe and effective treatment to enhance the cosmetic appearance of East Asian men with advanced AGA.

Body to Scalp: Evolving Trends in Body Hair Transplantation

Follicular unit extraction (FUE) is becoming an increasingly popular method for hair restoration. As FUE leaves behind no linear scars, it is more suitable to harvest from various body areas including beard, chest, and extremities in hirsute individuals. Body hair characteristics such as thickness, length, and hair cycle may not completely match to that of the scalp hair. The techniques of harvesting body hairs are more time consuming, requiring higher degree of skill than regular scalp FUE. Body hair transplantation can be successfully used either alone or in combination with scalp hair in advanced grades of baldness, for improving the cosmetic appearance of hairlines and in scarring alopecia when there is paucity of donor scalp hair. Harvesting of body hairs opens up a new viable donor source for hair restoration surgeons, especially in cases of advanced Norwood grades five and above of androgenetic alopecia.

The Role of Hair Restoration Surgery in Primary Cicatricial Alopecia

Primary scarring alopecias are a group of inflammatory conditions in which the main target of the inflammation is the hair follicle. They represent up to 7.3% of the hair loss cases presenting to specialty hair clinics. They are poorly understood, their pathogeneses are mostly unknown and their management is guided at best by the results of small case series and expert opinions. These alopecias are frequently referred to as a trichologic emergency as their progression can be rapid and the hair loss they induce is permanent. In view of the suboptimal solutions offered by the pharmacological treatments available and the significant emotional distress caused by these conditions, it is only normal for patients with scarring alopecias and their treating physicians alike to explore the prospects of surgical correction. This review attempts to summarize what is known about hair restoration surgery in scarring alopecia.

Cicatricial alopecia: What’s new in etiology?

Cicatricial alopecia is a rare, clinically diversified set of disorders causing permanent and irreversible hair loss, which often results in serious discomfort and patient’s mental problems.

Clinically, this form of irreversible hair loss is characterized by visible loss of hair follicle openings in the bald spots. Histologically, it consists in destroying a hair follicle and replacing it with fibrocartilage. Such disorders are perceived as primary if a hair follicle itself is the target of the disease process and secondary if hair follicles are damaged incidentally in the context of more general tissue damage (e.g. deep skin infections, thermal burns, trauma or ionizing radiation).

In this article we tried to summarize the knowledge on possible pathogenic mechanisms of cicatricial alopecia. The presented factors usually overlap and affect prognosis of particular patients. Their profound understanding may enable further research on the treatment methods of this challenging disease unit.

Body hair transplantation: case report of successful outcome

Transplantation of body hair in to scalp has been suggested as an option to treat extensive cases of baldness with poor donor scalp. However, evidence about its long-term efficacy is yet lacking, with very few published reports and the routine use of the technique is still controversial. We report the satisfactory outcome in a case of extensive baldness in whom hairs from different donor areas such as chest, abdomen, arms, thighs were transplanted on to scalp.
