“…According to Hwang et al hair follicles transplanted from the occipital scalp to lower leg took on the hair characteristics of leg hair and partially the same hair reversed their characteristics when transplanted to the nape of the neck. [32] This is supported by Woods and Campbell, who using chest hair micro grafts transplanted to the scalp showed extended growth and almost 4 times increase in their length to mimic growth characteristics of the native scalp hairs in the crown region.

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.

“…In another study of ours, hair transplantation from the occipital scalp to various recipient sites such as the lower leg, nape of the neck, palm, and lower back was performed, and it showed the decrease of the anagen period and the rate of growth when scalp hairs were transplanted to the body site. 2 Consequently, these observations suggested that the recipient site affects some characteristics of transplanted hairs, such as their growth rate and anagen phase. One uncertainty was whether body hair characteristics, such as growth rate and the anagen period, would be affected if the concept of recipient site influence was valid.…”

“…We suggested that the recipient site influences the growth characteristics of transplanted hairs such as growth rate and anagen period when transplanted scalp hairs were transplanted to different recipient sites such as the lower leg, neck, palm, hand dorsum, and eyebrow. 2,3 The purpose of this study was to evaluate whether the body hairs would keep their original growth characteristics when the body hairs were transplanted to the scalp area.…”

The authors have indicated no significant interest with commercial supporters. D r. Norman Orentreich provided the scientific basis for the field of hair transplantation, stating that the transposed grafted skin maintains its integrity and that characteristics such as texture, color, growth rate, anagen period, and the majority of these transplanted grafts behave independent of the recipient site. 1 The concept of ''donor dominance'' that he discovered formed the foundation of hair restoration surgery. We suggested that the recipient site influences the growth characteristics of transplanted hairs such as growth rate and anagen period when transplanted scalp hairs were transplanted to different recipient sites such as the lower leg, neck, palm, hand dorsum, and eyebrow. 2,3 The purpose of this study was to evaluate whether the body hairs would keep their original growth characteristics when the body hairs were transplanted to the scalp area. Case ReportIn 2005, a patient with male pattern baldness gave his consent for this study. Donor hairs were harvested from the chest area and the occipital scalp using the elliptical excision technique. We transplanted nine chest hairs (single-hair follicular units) to the right side of the frontal scalp ( Figure 1A, yellow circle) and the occipital hairs to the vertex ( Figure 1A, blue circle) using a KNU implanter. We tattooed one point on the right frontoparietal recess where no residual terminal or intermediate hairs were growing and kept a copy of the transplanted points on the cellophane adhesive tape. One year after the operation ( Figure 1B), iris scissors were used to cut nine transplanted chest hairs from the scalp and 14 original chest hairs. The length and caliber of each cut hair was then measured. Hairs were cut as close to the skin surface as possible to measure total hair length grown for 1 year. After the hairs were cut, they were allowed to grow for 4 weeks, and the length of the hairs was again measured. The difference in the hair growth rate per 4 weeks of the transplanted chest hairs and original chest hairs was analyzed.The transplanted chest hairs grew longer than the original chest hairs, 56.3 mm versus 28.5 mm, about two-fold increase in mean length after the 1-year follow-up period ( Figure 2). The hair growth rate also increased slightly after transplantation from the chest to the scalp: 10.4 mm/4 weeks for the transplanted hairs to the scalp and 8.9 mm/4 weeks for the original hairs. Mann-Whitney U test was used to analyze the difference between the transplanted and original chest hairs, so the value of p was less than .05 in the mean length and hair growth rate. The transplanted chest hairs showed several different growth characteristics. However, there was no

“…In this study, the mean survival rate of single-hair grafts of 73.6 7 7.6% correlated with patient's age. Hwang and associates 22 suggested that the recipient site affects some characteristics of transplanted hairs, such as their growth and survival rate. The survival rate on the lower leg was 60.2%.…”
