Volume/Frizz

[0220] Volume is the gain of body in a hair tress due to its humidity exposure or mechanical actions such as combing or friction of fibers. Frizz is the bristling of some fibers of hair that get apart from the tress body (fly-away effect). Volume/Frizz control test measures the variation in the shape of the hair tress after exposure to a high humidity environment, for a controlled period of time. The parameter measured is the number of pixels in the Image, as expression the gain of volume.

[0221] Protocol [0222] 5 afro hair tresses (5 g, 15 cm) were previously cleaned with SLES 10% solution for 1 minute. [0223] Test products were applied 5 times in each tress (0.5 mL of product+massaging for 1 minute, followed by 1 minute of rinsing at running water at 33° C., ±3° C.). [0224] Images at initial time (T0) were captured by Rumba System. [0225] Tresses were left at controlled environment (22° C., ±2° C.; 50% RH, ±5%) overnight for drying. [0226] Images at final time (T1) were then captured by Rumba System. [0227] The difference in the number of pixels between T1 and T0 was calculated for each tress. [0228] Comparisons among the treatments were performed, using T-Student test, considering 95% confidence interval.

[0229] The results are shown in Table 1; provided are data for volume and volume increase during drying (pixels).

[0233] Protocol by Image Analysis [0234] 5 Caucasian virgin tresses (1 g, 25 cm) were previously cleaned with SLES 10% solution for 1 minute. [0235] Test products were applied 5 times in each tress (0.1 mL of product+massaging for 1 minute, followed by 1 minute of rinsing at running water at 33° C., ±3° C.). Optionally, leave on was not rinsed. [0236] Curls were produced in the laboratory for each tress. [0237] Images at initial time (T0) were captured with Digital Camera Nikon D5200. [0238] Tresses were left at high humidity environment (25° C., ±2° C.; 70% RH, ±5%) for 15′, 30′, 1 h, 2 h and 4 h. [0239] Images at each time (T15′, T30′, T1h, T2h and T4h) were then acquired. [0240] The retention of the curls was analyzed. [0241] Comparisons among the treatments were performed, using T-Student test, considering 95% confidence interval.

Tensile Test

[0243] Tensile test refers to a method which measures different linear mechanical properties of the hair fiber. Parameters measured: [0244] Elastic Module: measure of the stiffness of a material. The higher is elastic module, the higher is its stiffness. [0245] Break extension: maximum extension achieved at breaking point. [0246] Stress at 15% strain: measure of the necessary mechanical tension to deform hair fiber in 15%. [0247] Break Stress: measure of the necessary mechanical tension to lead the hair fiber to breakage.

[0248] Protocol [0249] 3 Caucasian bleached hair tresses (5 g, 20 cm) were previously cleaned with SLES 10% solution for 1 minute. [0250] Test products were applied 5 times in each tress (0.5 mL of product+massaging for 1 minute, followed by 1 minute of rinsing at running water at 33° C., ±3° C.). [0251] Tresses were left at controlled environment (22° C., ±2° C.; 50% RH, ±5%) overnight for drying. [0252] 45 fibers from each treatment were collected randomly. They were fixed in metallic crimps one by one. [0253] Diameter measurements were executed; [0254] The fibers were sunk in water for 1 h and then tensile test was performed. [0255] Comparisons among the treatments were performed, using T-Student test, considering 95% confidence interval.

[0256] The results are shown in Table 3; provided are data for elastic module, stress at 15% strain, break extension and break stress.

Swelling Test

[0257] Through diameter measurements, it is possible to determine the level of swelling of a fiber of hair over time when in contact with water. The laser measures the variation in the fiber diameter as it absorbs water over a pre-determined time. According to the fiber condition or the film covering its surface, the level of swelling may change. The more damaged the hair, the more hydrophilic it is and, consequently, more swelling is noticed since most of the hair damages take the lipids, ceramides and other hydrophobic substances away from the hair. Parameter measured: [0258] Variation in hair diameter (%)

[0259] Protocol [0260] 3 Caucasian bleached hair tresses (5 g, 20 cm) were previously cleaned with SLES 10% solution for 1 minute. [0261] Test products were applied 5 times in each tress (0.5 mL of product+massaging for 1 minute, followed by 1 minute of rinsing at running water at 33° C., ±3° C.). [0262] Tresses were left at controlled environment (22° C., ±2° C.; 50% RH, ±5%) overnight for drying. [0263] 45 fibers from each treatment were collected randomly. They were fixed in plastic tabs one by one. [0264] Diameter measurements were executed and then swelling test was performed. [0265] Comparisons among the treatments were performed, using T-Student test, considering 95% confidence interval.

[0266] The results are shown in Table 4; provided are data for swelling as diameter variation.

Color Fading Evaluation

[0267] The color of the hair may be affected by chemical and light aggression. In order to evaluate the potential of products to protect the hair from presenting color fading, it is possible to measure color in an objective way, in which luminosity and chromatic variation are analyzed by L* a* b* scale and compared before and after hair exposure to these aggressive agents. Evaluated parameter: [0268] Total color variation (ΔE).

[0269] Determined Parameters [0270] Parameter L—luminosity, goes from 0 to 100 [0271] Parameter a—color from green to red, goes from −a to +a [0272] Parameter b—color from blue to yellow, goes from −b to +b [0273] Delta E—parameter calculated from the variation of L, a and b. Expresses the total color variation.
