Example 4—Straightening Test

[0098] 4.1-Straightening Process

[0099] The kit described in the previous Example 3 is used for straightening a frizzy, recalcitrant and indomitable hair of the Afro type, when it comes into contact with moisture.

[0100] A photo taken before treatment shows the hair in its natural state (FIG. 5).

[0101] The application of the composition according to the invention is performed according to the following protocol.

[0102] Step 1: Application of the Straightening Cream Directly on Dry Hair

[0103] The composition according to the invention is applied strands by strands from the root to the tip. Each strand is kneaded and combed in order to properly distribute the product.

[0104] Afterwards, the hair is covered with a cellophane and the composition is left to act for 30 minutes.

[0105] Step 2: Drying

[0106] Afterwards, the hair is heated in hot air with a hair dryer, by directing the blow of air from the root to the tip to lower the cuticle. 3 cm-wide strands are selected and maintained perpendicular to the scalp in order to be heated over their entire length.

[0107] Step 3: Rinsing

[0108] The entire hair is rinsed and a classic shampoo without Sodium Laureth Sulfate (SLS) is applied.

[0109] The shampoo is rinsed off and the «top coat» mask composition is applied, then left to stand for 5 minutes and rinsed.

[0110] Step 4: Straightening

[0111] Afterwards, the hair is hand-styled with a hair dryer.

[0112] 4.2-Obtained Results

[0113] It is observed that during straightening, the hair is straightened and put in place without the need to use a hair straightener.

[0114] A straightened hair is thus obtained simply in contact with the heat of the hair dryer, without having to resort to the effect of tension or intense heat of the hair straightener (FIG. 6).

[0115] The fiber is mastered, including after having been subjected for a period of 15 minutes to a steam treatment with a moisture content of 91% (FIG. 7).

[0116] Furthermore, the observed effects are long lasting (about three months).

Example 5—Comparative Test

[0117] A kit containing: [0118] a straightening composition in the form of a straightening cream comprising only but an amino acid and an alcohol (that is to say without protein and without vegetable oil); [0119] and a «top coat» mask comprising a protein; [0120] whose compositions are reported respectively in the following Tables 5 and 6 is prepared.

TABLE-US-00005 TABLE 5 Straightening composition Ingredients Quantity (% w/w) Water 51.9 Glycerin 2 Arginine 1 Cysteine 1.8 Glutamic acid 0.4 Alcohol 5 Caprylic capric triglyceride 5 Tocopherol 0.5 Aloe vera juice 20 Glyceryl stearate citrate 2 Hydroxypropyl starch phosphate 3 Cetearyl alcohol 2 Sodium stearoyl lactylate 1 Ceteareth-20 3 Phenoxyethanol 0.5 Dehydroacetic acid, benzyl alcohol 0.4 Perfume 0.5

TABLE-US-00006 TABLE 6 «top coat» mask Ingredients Quantity (% w/w) Water 80.6 Cetearyl alcohol 3.5 Cetrimonium chloride 6.6 Glycerin 0.5 Behentrimonium methosulfate, cetearyl alcohol 2 Polyquaternium-7 0.5 Shea Butter 2 Cetrimonium chloride, amodimethicone, trideceth-12 1 Lactic acid 0.05 Phenoxyethanol 0.4 Hydrolyzed collagen 0.4 Aminopropyl phenyl trimethicone 0.4 Guar hydroxypropyltrimonium chloride 0.1 PEG-90M 0.1 Hydrolyzed elastin 0.8 Panthenol 0.5 BHT 0.05 Perfume 0.5

[0121] A straightening test was subsequently performed with this composition according to a protocol identical to that described in Example 4.

[0122] A photo taken before treatment shows the hair in its natural state (FIG. 8).

[0123] After treatment, dull and dehydrated hair is observed. Furthermore, on contact with the heat of the hair dryer, the hair does not straighten but swells and takes on a very frothy appearance. Despite an attempt to recover by brushing, the result is very insufficient (FIG. 9).
