The current invention comprises methods and compositions for straightening hair. Using embodiments of the current invention, curly hair can be effectively and safely straightened by a method that is milder and less damaging than the current art and does not employ ingredients such as formaldehyde and glutaraldehyde that are considered noxious and raise significant toxicological concerns. In one or more embodiments of the invention, a low concentration of sodium hydroxide (˜0.5-0.6%) is applied prior to the application of an oil (preferably a vegetable oil), followed by treatment with a flat iron, or similar, heated to ˜180-200° C. In one or more alternative embodiments of the invention, the sodium hydroxide and oil-containing compositions are combined and applied to the hair in a single step. The improvements extended by this invention beyond the current art include: reduced damage to hair; reduced potential for damage to the skin and eyes; elimination of noxious chemicals; avoidance of chemical systems that are banned in a number of countries; greater resistance to reversion; longer lasting results; and as a consequence of these considerations, potential for home (non-professional) usage.

A hairbrush for hot curling. A brush body constituting a hairbrush is formed to have a substantially quadrangular sectional shape with rounded corners to thereby shorten a hair drying time and improve hair curling efficiency. A slippage prevention part is formed on the outer surface of each steel wire constituting a core element to increase frictional force between bristles and the steel wire, maintain the firmly fastened state of the bristles for an extended period of time and lengthen the lifetime of the hairbrush. A rounded part is formed on each end of each bristle through grinding to prevent damage to the skin of the head, ensure smooth combing of hair and increase the value of the hairbrush.

The present invention relates to an electric hair clipper blade assembly having a guide plate connected with a fixed blade and a movable blade that moves in a left and right direction or horizontal direction and a connection / fixed member. In particular, the present invention relates to an electric hair clipper blade assembly having fixed and movable blades with depths deeper than those of conventional fixed and movable blades and a blade body DLC-coated, on which a portion of the guide plate, the fixed blade, and the movable blade are formed, to maintain fairly good cutting power in cutting short hair or curly hair.

A hair straightening and / or pressing device for straightening and / or pressing coarse, thick, ethnic, kinky or curly hair can include two arms connected pivotally at one end. The arms can have opposing surfaces that can be heated. The heated surfaces can be featureless or include features. One or both surfaces can have rows of closely spaced, parallel blade shaped tines extending across substantially the entire width of the surface from one side of the device to another side of the device. The hair straightening device can have at least two different temperature settings selectable by a user. In certain implementations, one temperature setting may be lower than the other two settings and at a temperature that is not optimal for straightening hair. The other two temperature settings may be set to a temperature that is optimal for straightening hair of different types.

The invention discloses a refrigerating device used for a hair perming machine and the hair perming machine thereof, and relates to the hair perming machine. The refrigerating device comprises a block-shaped body or a heat dissipation type container; the container contains refrigerating materials, the block-shaped body or the heat dissipation type container and the refrigerating materials contained in the heat dissipation type container are put in a refrigerator together to be freezed, and the refrigerating device used for the hair perming machine is formed; an assembling structure capable of being fetched and assembled on the hair perming machine is arranged on the container or the block-shaped body, so that it is achieved that the container can be assembled on the hair perming machine in a fetched mode. The refrigerating materials can be refrigerating fluid, water, power materials, metal blocks, ceramic blocks or stones. According to the hair perming machine, the refrigerating device can be assembled at one or more free ends of clamping arms in a fetched mode; according to a curly hair type hair perming machine, and the refrigerating device can be assembled at one end, far away from a handle, of a curly hair cylinder body. The source of the refrigerating materials is wide and easy to obtain, the refrigerating cost is favorable to lower, and the popularization and application are facilitated. The cooling capacity is strong, the refrigerating temperature can reach below zero degrees Celsius, the cooling effect is good, and the use time is long after the cooling materials are cooled at one time. The hair can be permed and cooled quickly at the same time, the sizing effect is good, and the damage to the hair quality is small.
