Does the Recipient Site Influence the Hair Growth Characteristics in Hair Transplantation?

Aim: The purpose of this article is to prove the importance of autologous fat transfer (AFT) in scarring alopecia. Methods: We present a complete clinical report of 21 cases treated with a combined procedure of AFT and hair transplantation (HT) done in the last three years. Results: The main findings of this study are the constant, early and more predictable hair regrowth after the hair transplant done on a pre-treated scarring alopecia. Conclusion: Tissue regeneration through AFT can significantly improve hair growth in the area of scarring alopecia, underlining, once again, the tremendous potential of this approach. Future studies may need to be carried out.

Germinal Cells

Hair transplantation methods as generally practiced utilize grafting of full follicles. Recent experimental evidence suggests that germinal cells responsible for follicular growth and differentiation may reside in specific localized areas within the follicle. This study was performed to relate experimental evidence to practical hair transplantation and to discuss results obtained from implantation of ½ follicular grafts. The study was done on four male patients with androgenetic alopecia who underwent transplantation with follicular half autografts. A total of 697 grafts of the upper ½ follicles and 694 grafts of lower ½ follicles were implanted. The results demonstrated that 50 hair shafts were produced from 697 upper ½ grafts, and 152 hair shafts from 694 lower ½ grafts. The conclusion is that the low percentage of terminal hair growth from ½ follicular grafts preclude this technique as an alternative method for cosmetic hair transplantation.

AbstractOftentimes, multiple treatment modalities are indicated for the management of trauma to the face. When this trauma involves a hair-bearing area, such as the eyebrow, eyelid, or beard region, hair transplantation can be an effective modality. While most of these facial hair transplants are performed for elective cosmetic indications, advanced techniques of hair transplantation can assure aesthetic outcomes in the optimizing of appearance after trauma. Because hair regrowth requires a good recipient bed, adjuvant therapies to promote vascularization, such as fat transfer and platelet-rich plasma, can be applied in conjunction with hair transplantation. The authors review the indications and the essential techniques of graft harvesting by follicular unit extraction and follicular unit grafting, and recipient site formation and graft planting and management, and present different case examples illustrating these technique.

Facial Shape

Introduction/Objective. Hair transplantation is one of the fastest evolving procedures in aesthetic surgery and is accompanied by continuous improvement of new techniques. Hairline planning is one of the most important steps in hair transplantation. The shape of the hair also varies depending on the variation of facial shape so it is very important when determining hair direction and making holes for future grafts. Methods. We used ordinary 18 gauge injection needles whose number was the same as the number of micrographs we planned for transplantation. Needles are administered in pile growth direction and angle, starting from the first row, and then proceeding to the second one and so on, until we insert all prepared needles. We insert them one in front of the other with a precision ease for future follicles. Results. In all 56 patients, we obtained natural hair growth. Inserting the needles reduced bleeding and the average time of the operation was three hours. The success of grafting was 95%. We only had one infection in one patient. Hair growth corresponded to the needle insertion. After a year of transplantation at the last control, the patient?s satisfaction was 100%. Conclusion. By using the same number of needles as the number of grafts we reduced operating time, we had a better determination of the direction of hair growth, we can prevent follicular extraction that can be caused by new needle insertion, and this technique achieved a good aesthetic result.

Postoperative Length

The effect on hair growth of wounding the lower region of whisker follicles, and in particular the dermal papilla, with sharply pointed tungsten needles was studied in adult hooded rats. Following injury hair growth ceased, but was subsequently resumed. While it might have been anticipated that follicle wounding would have a negative effect on whisker length, regular postoperative length measurements revealed that in follicles where cellular material was not displaced from the follicle by the original manipulation, 50 % of the subsequent hairs produced were longer than their counterparts on the opposite side of the face, with 25 % shorter and 25 % with their length unchanged. In every case increased hair length was achieved by a prolongation of the g that the factors which control the duration of the hair cycle and fibre growth rate are independent in vibrissa follicles. Since removal of most of the epidermal component by plucking of the hair just prior to injury produced equivalent hair length increases, this implicated the proximal dermal components as being mainly responsible for the observed changes.
