2. straighten your hair and find a rubber band to tie it to the desired length.
3. Cut horizontally along the rubber band with scissors. Do it.
4, the hair cut out in this way has a layered feeling, and after cutting, it is a curved V shape, which is convenient and easy to operate.
Hair care, also known as hair care, is often used to trim hair, making people clean and tidy, which has the effect of beauty beauty. Hairdressing can be a family life activity, and family and friends help each other. But hairdressing can also be regarded as one of 72 occupations, which is the occupation of hairdressers in hair salons and barbershops.
Hairdressing usually refers to basic hair care, while beautifying hair is called hairdressing. But besides a haircut, a "haircut package" may also include shampoo, blow-drying, dyeing, dressing, styling, manicure and massage.

physiological property
Hair can be divided into papillae, hair follicle, hair root and hair shaft from bottom to top. The physiological characteristics and functions of hair mainly depend on nipples, hair follicles and sebaceous glands under the scalp epidermis.
Hair follicle is the part of hair root in dermis, which consists of inner hair root sheath, outer hair root sheath and hair ball. Inner hair root sheath is the sheath layer directly adjacent to hair in the later stage of hair development. The inner hair root sheath is a hard thick-walled keratinized tube, which determines the shape of the cross section when the hair grows. The lower part of the inner hair sheath has three layers: Huxley sheath, Henler sheath and the surface layer of the inner hair root sheath.
Before hair keratinization, the inner hair root sheath grows with hair, and its source is the cells propagated at the bottom of hair follicle. Near the epidermis, the inner hair root sheath is separated from the epidermis and hair follicles.
Papillary process is the lowest end of hair follicle, which is connected with capillaries and nerve endings. At the bottom of the hair follicle, epidermal cells continue to divide and differentiate. These epidermal cells differentiate in different ways to form different components of hair (such as cortex, epidermis and medulla), and the outermost cells form the inner hair root sheath. At this stage, the cells are soft and non-keratinized.
The function of sebaceous glands is to secrete sebum and squeeze it out through the sebum tube. When the hair passes through the sebum tube, it will take away the sebum squeezed out of the sebum tube. Sebum provides natural protection for hair and gives it luster and waterproof performance. Hair muscle is a small muscle organ connected with epidermis, which depends on the external physiological environment. Hairy muscles can stretch or contract.
The drop in temperature or the action of adrenal hormones can pull the hair follicle to a higher position and make the hair stand up.
Hair cortex is the main component of hair, which is composed of slender cells parallel to the long axis of hair. There are about 10 mm tension filaments and interfiber matrix in these cells, which determine the main physiological characteristics of hair. Filaments are composed of fibrin, 50% of which are spiral, and the matrix is composed of cystine-rich non-spirochete proteins.
These protein are synthesized at the lower end of the hair follicle, and cysteine is converted into cystine in the final stage of synthesis.
The physical properties of hair are related to its chemical composition. Hair will swell soon after soaking in water, and the weight after swelling will increase by about 40% compared with that before soaking in water. This phenomenon of swelling in water shows that hair is almost pure protein component with little lipid content. Hair has a strong duality, because the arrangement of filaments in cells is parallel to the long axis of hair.
