Hair removal using lightGEM –PL (Geometrical Energy Management) technology manages to deposit most of the energy in a plane coinciding with the position of the hair follicles. The broadband enables the treatment in hair types, which are traditionally hard to treat - such as feathery hair or bright hair.Investigations (Anderson et Al) has clearly demonstrated that a flash of high intensity light penetrated through the epidermis, is absorbed and assimilated in the hair bulbous region, and acts as inhibitor to the hair follicle through temporarily temperature rise and agglutination. The follicle has several parts that interest us. Dermal papilla - The dermal papilla directs and dictates the embryonic generation of a hair follicle and it also retains this instructive ability throughout the life of the hair follicle. It consists of a highly active group of cells shown to be capable of inducing follicle development from the epidermis and production of hair fiber (Oliver 1966a, Oliver 1966b, Oliver 1967). The bigger the Dermal Papilla is, the more cells it has - the thicker the hair fiber that the hair follicle produces. Basement Lamina - a thin layer of cells that separates the Dermal Papilla form the hair sheath cells. Providing a barrier between the dermis and epidermis. Matrix cells - Epidermal derived cells close to the Dermal Papilla. These cells remain undifferentiated and focus on multiplying and proliferating to produce more cells. Those cells made in the center of the hair follicle are destined to become part of the hair fiber and are called Cortex (cortical) cells. Cortex Cells - Cells that are made by the matrix cells, aimed to become a part of the hair fiber. As these cells multiply, the constant stream of production pushes the cells upward towards the skin surface. As they move up the hair follicle they begin to differentiate into particular cell types. The cortex cells change from a round into a flattened appearance. They are squeezed together into layers (lamella). If the hair follicle contains melanocyte cells then melanin pigment is incorporated into the cortex cells. These cortex cells become keratinized and harden. As they do so it becomes impossible for the cells to function properly and the cells die. The keratinized cells are then pushed away from the hair bulb region and upwards as new cells come in behind. The cortex cells are now part of the dead keratinized fiber. Which is the hair that we see. Capillaries - small blood vessels that brings food and oxygen to the hair follicles and takes away the CO2 and waste of the cells metabolic cycle. When we give a pulse of light, the light penetrates the epidermis and absorbs in the cells. The darker the area the more energy it will absorb. As you can see in the picture, the darkest area is the area of the matrix cells (the cells that produce the hair fiber cells). That is because of the melanin, which is inside these cells. |
