Wigs For Natural Hair
Basically, darker areas absorb more of the laser beam than lighter areas. If skin and hair follicles are the same color or the skin is dark, the skin will absorb too much light, which could cause skin damage. Darker skin can be treated but it's more difficult it takes longer. As far as hair color goes, coarse dark hair is best and blond and red hair are worse. It should be remembered that results can be difficult to predict and they may be disappointing.The cost and inconvenience of using laser treatment to remove pubic hair should also be considered. It can be expensive and there are many pre-treatment and post-treatment restrictions. For example, exposure to sun without a sun block should be avoided for six weeks after laser hair removal and waxing and shaving for two weeks. After treatment skin will feel burned for two to three hours and small blisters may appear.The innermost layer of cells undergoes keratinization to form the medulla. The medulla is the core of the hair shaft. Following the medulla is the layer called the cortex. The cortex forms most of the internal structure of the hair. This layer undergoes keratinization more than the medulla. The third layer of the hair is the cuticle. Overlapping keratin plates form this layer. This arrangement of the cuticle prevents matting of the hair follicle. The hair shaft is composed only of these three layers. It does not contain the fourth and fifth layers. The fourth layer of the hair is the internal root sheath. This layer is almost unkeratinized and disappears at the level of sebaceous glands. This leaves a space through which the glands secrete sebum and coat the hair shaft. The fifth and the outermost layer is the external root sheath.
