    Indian Dermatol Online J 2017 May-Jun;8(3):167-175
    Cosmazone Hair Restoration Clinics, Mumbai-Gwalior-Delhi, India.
    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. Read More

    Pretrimmed versus Direct Nonshaven Follicular Unit Extraction.
    Plast Reconstr Surg Glob Open 2017 Mar 16;5(3):e1261. Epub 2017 Mar 16.
    Dana Plastic Surgery Clinic, Gangnam-gu, Seoul, Korea.
    Background: Shaving the donor area is one of the major deterrents preventing hair transplant patients from selecting follicular unit extraction (FUE). A minimal shaved donor area is possible in strip surgery, but the strip method is not applicable if the patient wishes to avoid a linear donor scar, wishes to minimize postoperative pain, or has insufficient scalp laxity. In these cases, nonshaven FUE (NS-FUE) is potentially a very good choice. Read More

    Innovative modified hair follicle harvesting technique with reverse rake scalp elevator for lower occipital donor area in follicular unit extraction hair transplantation.
    Indian J Plast Surg 2016 Sep-Dec;49(3):390-396
    Department of Plastic Surgery, Grant Government Medical College and Sir J. J. Group of Hospitals, Mumbai, Maharashtra, India.
    Follicular 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).
