2. Good coordination between the rolling knife and the comb: generally, the operation of the rolling knife should be carried out together with the comb. The teeth of the rolling knife and the comb are obliquely crossed, and the comb teeth cut the hair, which is convenient for the rolling knife to curl the hair. At the same time, the comb plays a foil role, making the rolling knife more stable when curling the hair.
3. The hand curling knife should be operated according to the characteristics of the head contour: the head is a spherical contour, and the hair should be curled according to the spherical contour of the head. For example, when curling the hair on the upper and rear parts of the ear, the hand-curling knife is inclined straight upward, otherwise the handle of the hand-curling knife will touch the ear and the back neck, and it is difficult for the hand-curling knife to keep a certain angle. Generally, the hand-made knife will press on the skin first, and then the hand-made knife will gradually leave the skin and roll up at a certain angle to make the hair grow and shape.
4. Roll the hand-made knife faster, slowly and evenly. Roll one part of the hair first and then another part of the hair, so that all parts of the hair are evenly rolled.
