Hair loss, in particular androgenetic alopecia, has troubled humans since the dawn of history. Treatment options for hair restoration have undergone massive transformation from punch grafting to follicular unit transplantation. Current surgical treatment options in hair restoration fall broadly under two categories, follicular unit transplantation most commonly known as strip method and follicular unit extraction (FUE). The strip method though widely used initially is not so common now due to its fair share of disadvantages ranging from linear donor scar, scar widening to strip overharvesting and wastage of grafts. Follicular unit excision (FUE) was introduced as an alternative method for extraction of grafts to combat the donor linear scar produced by strip method but the disadvantages of FUE include the number of grafts harvested in a single session, moth eaten appearance of donor area caused by over extraction of grafts and harvesting from outside the safe zone. Newer developments like extraction of axillary hair, body hair and pubic hair have been sought to overcome the limitations of number of grafts harvested in a single session of FUE. With more patients now affected by alopecia in their early 20s, there is an ever-increasing demand from the patients for the youthful hairline and hence the focus has shifted towards mega and giga sessions of hair transplantation which pose danger of over extraction of grafts leading to depletion of available donor sites. This article elaborates the combined sequential strip and FUE method along with an intraoperative calculation model to overcome the limitations of over extraction and wastage of grafts. (1) Combination of techniques Strip method with FUE. (2) An intraoperative calculation model that aids in limiting over extraction and wastage of grafts. (3) It is a real time model which can be applied in practice with ease.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

脱发，特别是雄激素性脱发，自人类历史之初就一直困扰着人类。头发修复的治疗选择已经从打孔移植发生了巨大的转变到毛囊单位移植。目前头发修复的手术治疗选择广泛地分为两类，最常见的毛囊单位移植俗称条带法和毛囊单位提取（FUE）。尽管条带法最初被广泛使用，但由于其线性供体疤痕、疤痕变宽、条带过度采集和移植物浪费等诸多缺点，现在已不那么常见。毛囊单位切除（FUE）作为提取移植物的替代方法被引入，以克服条带法产生的供体线性疤痕，但 FUE 的缺点包括单次采集的移植物数量、由于过度提取移植物导致供体区域出现虫蚀外观以及从安全区外采集。为了克服单次 FUE 采集移植物数量的限制，人们一直在寻找提取腋毛、体毛和阴毛的新方法。随着越来越多的 20 多岁的患者受到脱发的影响，患者对年轻发际线的需求不断增加，因此，人们的注意力转向了 Mega 和 Giga 植发手术，这些手术存在过度提取移植物导致可用供体部位枯竭的风险。本文阐述了联合序贯条带法和 FUE 方法，以及术中计算模型，以克服过度提取和移植物浪费的限制。（1）技术组合 条带法与 FUE。（2）一种术中计算模型，有助于限制过度提取和移植物浪费。（3）这是一个实时模型，可以轻松应用于实践。证据水平 IV 本杂志要求作者为每篇文章分配一个证据水平。有关这些循证医学评级的完整描述，请参阅目录或在线作者指南 www.springer.com/00266 。
