Interesting Facts About LASER Hair Removal Interesting facts about LASER hair removal Removing unwanted hair is an increasing trend in a beauty conscious, striving-for-the-best society. In the home based treatment, waxing, threading, bleaching, plucking, shaving and epilators are the most common. Electrolysis is another method commonly used by many non-medical professions such as beauty parlours, hair salons, etc. wherein electric current is used to burn hair follicles using probes / electrodes. However electrolysis is an operator dependent procedure and the end results may vary. LASER Hair Removal (LHR) or light based technology is a more permanent method. BRIEF OVERVIEW OF HAIR: A single hair follicle is divided anatomically into 3 parts - infundibulum or the visible portion, isthmus and inferior portion Stem cells in hair follicle regenerate at the base / bulb of the hair Hair growth cycle: Is divided into three phases: anagen or the growth phase, catagen or the degradation phase and telogen or the resting phase. At any time, all three phases co-exist in a hair follicle HAIR TYPES: The various types of hair are: Lanugo or fine hair normally seen fetal stage or post delivery. Vellus or non-pigmented hair. Terminal or coarse hair. Colour of the hair is produced by melanin. Disorders of excess hair growth: 1. Hypertrichosis – excess hair growth at any site non-hormonal dependent 2. Hirsutism – an abnormal male-pattern hair growth in women eg., over face and chest. It is hormone dependent TYPES OF LASER: The various LASERs used for hair reduction are: Nd:YAG (long pulsed) IPL (Intensed Pulsed Light) Diode LASER Long pulsed Ruby LASER Long pulsed Alexandrite Fluorescent pulsed light PATIENT SELECTION: Medical history should include history of menstrual irregularity, thyroid problem, history of medicine use for any other problem and any other endocrine abnormality Patients with history of photosensitivity / skin infection (Herpes infection) Patients with history of keloid / scar to be avoided In either case, patient consent has to be sought prior to commencing of treatment Patients with realistic expectations PRE-OPERATIVE: Informed consent – Prior to LASER sitting, patient should be informed about the mechanism of action and potential side effects, and a signed consent should be taken from the patient Topical anaesthesia – Topical lidocaine or EMLA cream may be applied for 45-60 minutes prior to the procedure. This helps in reducing the pain associated with LASER Cooled room – An air conditioned room to provide soothing effect on the skin during the procedure Protective eye cover to prevent any retinal damage Ice pack cooling before, during and after the procedure is also advised POST-OPERATIVE: Erythema and edema appears around the treated hair follicle and may last for 2-3 days. Cooling with ice pack and corticosteroid cream may be used Use of a potent sunscreen and other sun-protective measures (hat and umbrella) to be used in the post-LASER period, as the skin is sensitive during that time Each sitting will cause reduction of 10-15% hair and patient should be advised about being “PATIENT” and be regular with LHR sittings Paradoxical hypertrichosis or increase in hair density may occur after any sitting as hair root may be upturned by the LASER Article Source http://www.skinclinicbangalore.com/post/interesting-facts-about-laser-hair- removal/1533 .

Hair is a derivative of the epidermis and consists of two distinct parts: the follicle and the hair shaft. The follicle is the essential unit for the generation of hair. The hair shaft consists of a cortex and cuticle cells, and a medulla for some types of hairs. Hair follicle has a continuous growth and rest sequence named hair cycle. The duration of growth and rest cycles is coordinated by many endocrine, vascular and neural stimuli and depends not only on localization of the hair but also on various factors, like age and nutritional habits. Distinctive anatomy and physiology of hair follicle are presented in this chapter. Extensive knowledge on anatomical and physiological aspects of hair can contribute to understand and heal different hair disorders. Keywords: hair, follicle, anatomy, physiology, shaft 1. Introduction The hair follicle is one of the characteristic features of mammals serves as a unique miniorgan (Figure 1). In humans, hair has various functions such as protection against external factors, sebum, apocrine sweat and pheromones production and thermoregulation. The hair also plays important roles for the individual’s social and sexual interaction [1, 2].

  • Gender and Hair Politics: an African Philosophical Analysis
    Gender and Hair Politics: An African Philosophical Analysis by Sharon Adetutu Omotoso, PhD [email protected] Institute of African Studies University of Ibadan, Nigeria ABSTRACT One wonders if there is anything called philosophy of hair. It may be argued in some philosophy quarters, that to endorse any philosophy of hair is to strip philosophy of its intellectual nature, relegating it into realms of trivialities. While anthropologists, sociologists, psychologists and scholars in the sciences have attempted discussing hair issues, philosophers have paid minimal attention based largely on a claim that there are more important life issues to philosophize. While ‘head’ (ori in Yoruba language) as a concept in African Philosophy has been widely theorized, very little work has been done on hair as a part of the head. Consequently, this paper argues that the importance of hair in the development of social constructs of the body puts forth the need for a gendered study of its philosophy and politics. Politics of hair in Africa is interesting and highly debatable yet overlooked by existing literatures. Using methods of critical analysis, reflective argumentation, deconstruction and reconstruction to carefully consider social, economic, cultural and religious dimensions in the politics of hair among men and women, this work draws out the implications for Africa’s holistic development. Dr Sharon Adetutu OMOTOSO is currently with the Gender Studies Program at the Institute of African Studies, University of Ibadan, Nigeria where she coordinates the Women’s Research and Documentation Centre (WORDOC). She is a a Chartered Mediator & Conciliator, Senior Research Fellow Institut Français de Recherche en Afrique (IFRA) and Research Fellow (Gender/Women Issues) of the Ibadan School of Government and Public Policy (ISGPP).

Hypertrichosis lanuginosa acquisita (HLA) is a Cancer immunohistochemistry revealed 95% cutaneous paraneoplastic syndrome characterized by a growth of long, thin, and nonpigmented hair covering the face and extending into the trunk and extremities. Malignancies of the lung, colon, and breast are most common with HLA, though other malignancies have been described [1,2]. Because of HLA’s insidious and asymptomatic course, diagnosis can take up to two years [1]. Paraneoplastic conditions involving the skin are readily accessible and identifiable. With approximately 70 cases in the literature, clinicians may be unfamiliar with HLA. Nonetheless, recognition and early diagnosis of cancer are crucial in improving overall outcomes. We report a case of HLA to emphasize the importance of screening for HLA to shorten the delay in diagnosis. Case Synopsis A 38-year-old woman presented with a 2-year history of facial hair growth.

IT'S NOT JUST HAIR: HISTORICAL AND CULTURAL CONSIDERATIONS FOR AN EMERGING TECHNOLOGY DEBORAH PERGAMENT* INTRODUCTION Nothing is more indicative of the importance currently being attached to hair growth by the general populace than the barrage of cases reaching the courts evidencing the attempt by one segment of society to control the plumage of another. -Justice William 0. Douglas Justice Douglas wrote those lines twenty-five years ago during a time when the nation and the court were examining the right of the state to control the appearance and actions of individuals purposefully attempting to flaunt social conventions about gender, race, and status through both action and physical appearance.' Nothing symbolized the struggle more than the long flowing tresses of white youths identified with the hippie movement 2 or the large "Afro" hairstyles of prominent African-American radical activists like Angela Davis.

    Hair Analysis ©2005, 2004, 2003, 2001, 1999 by David A. Katz. All rights reserved. Hair can be important physical evidence at a crime scene. Hair normally falls from the body over the course of a day. It will stick to a number of materials, especially fabric and clothing. Hair is not easily destroyed, even with exposure to moisture and decomposition of accompanying tissue. There are three types of hair usually seen in animals: Vibrissa. These are the whiskers of many animals. They are normally tactile and sensitive, such as the whiskers on a cat. Bristle. This is the coarse bristle that provides an animal with a protective coat. These guard hairs can readily be identified by their distinctive appearance and morphology between various animal families. Wool. Wool or fur provides insulation from wet and cold. These fine hairs cover the bodies of all mammals. Head and body hair of humans is classified as intermediate hair combining the characteristics of bristle and wool hairs. Four types of hair appear on the bodies of humans: Primordial hairs appear as early as the 3rd month of gestation, growing on the upper lip, the eyebrows, the palms and soles of the fetus. They gradually disappear and are replaced by softer lanugo hair over the entire body. Lanugo hairs are normally shed after the 6th month of gestation. They are fine, soft, unmedullated, and normally unpigmented hairs. The surface of lanugo hair is smooth with almost indiscriminate scales. It is replaced by vellus and terminal hairs. Lanugo hair is often observed on an aborted fetus and can be useful in investigation of possible infanticide.
