Methods and kits for treating hair or preventing damage in the relaxing of hair are disclosed herein. Hair that is damaged during a relaxing treatment with hydroxide-containing relaxing agents, can be treated with formulations containing one or more active agents. The active agent formulations can be applied simultaneously with the hair relaxing formulation, or optionally applied immediately following application of the relaxing formulation, to reduce damage and breakage. Use of the active agent formulation along with a relaxing treatment can be used to control the level of curl achieved or retained in the relaxed hair, as compared to the natural amount of curl in the untreated hair.

A system, computer readable medium and method for selective brightening of hair, the method may include or may be preceded by applying at least one photosensitive material to the hair. The method may also include forming at least one pattern of brightened hair by illuminating the hair by at least one pattern of illumination.

The present invention relates to a process for treating hair wherein the hair is semi permanently shaped and subsequently reshaped with the application of an aqueous composition comprising catechin and/or resorcinol and their derivatives.

Present invention relates to a process for permanent waving keratin fibers, especially human hair, for achieving durable waves wherein fibers are treated with a reducing composition, a non-reducing and non-oxidizing alkaline composition, a non-reducing and non-oxidizing acidic composition and finally an oxidizing composition wherein after processing the reducing composition the fibers are rinsed off.

A hair treatment method, including the step of spraying onto the hair a composition for changing the form of the hair, notably a permanent-waving or curl-reducing composition, using a device, called a low flowrate device, comprising at least two nozzles oriented such that their respective jets collide, these nozzles being supplied with said composition at pressure, the total flowrate of composition delivered by the nozzles being between 0.1 and 3 L/min, preferably between 0.2 and 2 L/min, and even more preferably between 0.3 and 1 L/min.
