, Change the shape of corrugated curve, there are two: 1. Physical effects - the winding roll bar fixed on the top of the hair. 2. Chemical reaction - the reduction and oxidation of perm (in and out before treatment) effect. In order to successfully complete corrugated perm curves change, we must better understand when the hair is wound around the perm rod, what kind of changes will occur (the shape of the pattern, will roll, etc.) and wipe the hair perm solution which will produce chemical reaction (reduction in oxidation \
hair fixed on the physical effects of the winding roll bar effect on the physical form, but it will not pull hair, the lowest stretch of the circumstances to maintain maximum tension. And the completion of the winding force uniform hair perm winding process was correct to be fully immersed in the hair perm solution, so that expansion of hair reduction (of different size and shape of the volume there are different amount of winding rods method, so as to form various sizes of small ripple (curl) and the shape of the pattern.)

hair shaft is exposed outside the skin part, that the visible part of hair from the keratinized cells. Organizations can be divided into epidermis, cortex and hair pulp layers. Containing melanin from the hair shaft composed of elongated cells, the cytoplasm containing melanin granules, melanin to hair color rendering. The number and melanin content of hair color related.
hair root is the part buried in the skin, is the root of the hair. Hair root length in the skin can not see,[link widoczny dla zalogowanych], and is surrounded by hair follicles. Hair follicle is composed of epithelial tissue and connective tissue sheath capsule was formed by the epidermal growth down the cystic structure,[link widoczny dla zalogowanych], the outside coated with a layer of skin evolved from the fibrous sheath. The end of the hair root and hair follicle enlargement, said the hair bulb. Active hair bulb cell division, is the hair growing point. Hair bulb at the bottom of depression, which broke into the connective tissue to form a dermal papilla. Dermal papilla contains capillaries and nerve endings, can nutrition hair bulb, and sensory function. If the atrophy or destruction of dermal papilla, hair stop growing and fall off gradually by
. There are a bunch of hair follicles on one side of the oblique muscle, known as the standing hair muscle. Li Mao muscle even in the hair follicles the lower end of the other end in the superficial dermis, muscle contraction when standing hair, the hair can be erected. Some small blood vessels distributed through the dermis to the hair bulb, the supply of its role as part of the hair bulb of hair growth and nutrition.
different with age, will change the nature of hair, same hair follicles to grow hair is not the same. During puberty, axillary and pubic area president of the bristles of the pubic hair, armpit hair instead of vellus hair; to old age,[link widoczny dla zalogowanych], scalp hair follicles tend to return to vellus hair to men's most famous, the same situation found in the armpits and pubic Ministry to women than the.
