AbstractFollicular unit extraction (FUE), now named as follicular unit excision, is one of the methods of harvesting hair follicles from the donor area for implanting in the recipient area. The occipital scalp area is the most common donor area, but nonscalp donor areas like beard, chest, and other hairy body parts can be used as donor hair follicle area. The extraction of the hair follicle leaves a tiny circular scar over the donor area. Over the past 20 years, various devices for FUE have been developed, starting from manual, simple motorized to highly advanced motors with rotation, oscillation, and vibration. Similarly, different types of punch are used: dull, sharp, ultrasharp, serrated, hybrid and specially designed punch blade for long hair follicles harvesting in various diameters from 0.7 mm to 1.1 mm. The follicles can be harvested either by manual method or by motorized method.

ABSTRACTFollicular unit extraction (FUE) is one of the widely practiced minimally invasive follicular harvesting techniques employed during hair transplantation. FUE technique has an advantage of utilising lower occipital area and supra-auricular region as a safe donor area described by Unger, in addition to the standard occipital donor area used in strip method (follicular unit transplant). Despite its potential advantages such as rapid recovery, minimal scarring and reduced post-operative pain; its widespread acceptance is limited due to various factors in variable contribution like steeper learning curve and potentially higher follicular transection rates (FTRs). The main practical drawbacks in harvesting FUE from lower occipital donor region that lie inferior to the standard donor area, is its acute angle (10°–15°) of emergent hair from scalp skin, higher variance angle (15°–35°) between hairs below the skin and hair exit angle above the skin and comparatively loose scalp, preventing to provide stable platform for punching. Hair transplant surgeon faces difficulty in aligning and engaging the FUE punch leading to very high hair follicle transection rate, and therefore, it is not a preferred site for harvesting follicles in FUE. Authors description of modified technique using reverse rake scalp elevator helps in negating the acute angle of the hair follicles exit from scalp skin and reducing the variance angle between emergent hair and hair below the skin in lower occipital region thereby reducing FTR. Furthermore, an added advantage of reducing the overall operative time and surgeon fatigue, improve donor area healing, availability of a comparatively larger donor area which increases the confidence of the beginners. This method will be of help as it is easy to duplicate and follow by novice hair transplant surgeons and also for those who are routinely doing mega hair transplants sessions.

AbstractThis article is mainly aimed to delve into the history of hair transplant and its evolution in India. As a plastic surgeon in practice for the past 35 years, I have seen hair transplant surgery undergoing various transformations starting with initial use of plugs and flaps. Scalp reduction surgery also played an important role. Plugs slowly gave way to mini- and micrografts. With the incorporation of the microscope and popularizing of strip surgery and improved slivering techniques, mega sessions came to the fore thereby covering large areas. Follicular unit extraction and use of body hair have also been discussed.

Abstract Background Different morphological structures of hairs having properties like defense and camouflage help animals survive in the wild environment. Horse is one of the rare kinds of animals with complex hair phenotypes in one individual; however, knowledge of horse hair follicle is limited in literature and their molecular basis remains unclear. Therefore, the investigation of horse hair follicle morphogenesis and pigmentogenesis attracts considerable interest. Result Histological studies revealed the morphology and pigment synthesis of hair follicles are different in between four different parts (mane, dorsal part, tail, and fetlock) of the bay Mongolian horse. Hair follicle size, density, and cycle are strongly associated with the activity of alkaline phosphatase (ALP). We observed a great difference in gene expression between the mane, tail, and fetlock, which had a greater different gene expression pattern compared with the dorsal part through transcriptomics. The development of the hair follicle in all four parts was related to angiogenesis, stem cells, Wnt, and IGF signaling pathways. Pigmentogenesis-related pathways were involved in their hair follicle pigment synthesis. Conclusions Hair follicle morphology and the activity of ALP differ among four body parts in bay Mongolian horse. Hair follicles of the different body parts of the are not synchronized in their cycle stages. GO terms show a regional specificity pattern between different skin parts of the bay Mongolian horse. These results provide an insight into the understanding of the biological mechanism of the hair follicle in other mammals.
