Embodiment 1

[0111]Usefigure 1 The total flow of the composition delivered by the nozzle is 2 l / min in accordance with the apparatus shown in the present invention. The nozzle has a diameter of 0.6 mm, and the angle between the nozzles is 90 °, and the supply pressure of the nozzle is 10 bar.

[0112]A product of modified form is made using a weight amount of TGA (ammonium mercaptoacetate), a proper amount of pH 9, and water (formula A).

[0113]The device is set to inject the recipe A by weight of 80%. In other words, MC / (MC + Me) = 0.8, where MC is the weight of the formulation A in the stream in the flow per unit time, and ME is the amount of water constituting the stream prior to mixing with the formulation.

[0114]When testing, the apparatus uses hot water (40 ° C) of the supply and 30 cm straight hair (Japanese style).

[0115]The hair is rolled up to a reel having a diameter of 13 mm, and then the plurality of coils from the hair blow sweeping hair delivery in the handset for 15 seconds, and the...

Embodiment 1a

[0119]On the first head, the exposure time on both sides is 10 minutes, then rinsing, and 8 volumes of the 8 volume of the hydrogen peroxide composition of pH 3.2 for 5 minutes. Next, the last flush is made and the hair is expanded.

[0120]In the case of the present invention, it is found that the end of the hair is very critically curled (the average curvature diameter is 30 mm), and in the case of the control, the end of the hair is almost no curl (the average curvature diameter is 44 mm). In both cases, the roots are the same.

Embodiment 1b

[0122]On the second head, the control was repeated at a 20 minute long exposure time, and then rinsed, and 8 volumes of the 8 volumes of the hydrogen peroxide composition of pH 3.2 were administered for 5 minutes. Perform the final flush and expand your hair. In the case of a control, it was found that the end of the hair was very curl (the curvature diameter was 30 mm), but the root was damaged.

Abstract

The present invention relates to a hair treatment method, comprising the step consisting in spraying onto the hair a composition for changing the form of the hair, notably a permanent-waving or curl-reducing composition, using a device (10), called a low flowrate device, comprising at least two nozzles (13) 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 (13) being between 0.1 and 3L / min, preferably between 0.2 and 2L / min, and even more preferably between 0.3 and 1L / min.

Description

Technical field[0001]The present invention relates to a method of hair treatment.Background technique[0002]In the field of changing the hair form, in order to achieve curling, or decrease or straighten, the composition is required and the composition is contacted with the hair. Such compositions are based on active substances such as an alkaline reagent having a sulfur reducing agent or having very basic pH. They either have a bad smell, or stimulate the skin, which leads to the approach to reducing the application of contact.[0003]In the case of perm (for hair curling), a composition based on the sulfur-containing component (e.g., thiol or sulfite) is used. In the past, the practice is to apply the product to the hair first, then roll the hair onto the reel. Today, it is recommended to roll the hair onto the reel, and then apply the product to the hair after the volume is completed, thereby limiting contact with the hand. The problem that has been discovered is that the product is ...
