• hair swatches (1 g, 27 cm) were prepared for each experiment.
• the hair swatch was washed with clarifying shampoo and then placed on a hot plate at 30°C.
• 0.4 g of each of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 4 was applied on the hair swatch by a brush.
• the hair swatch was then kept at 24°C and under 40% relative humidity for 30 minutes, and then dried with a blow drier under ambient conditions to obtain a treated hair swatch.
• the volume of the treated hair swatch was measured by taking an image with a camera (Powershot SX620 HS from Canon). Each of the dried hair swatches was hung in front of a white background (backlight) sheet and the image of the hair swatch was obtained by the camera. With the help of customized image analysis software, the obtained image was converted into a gray-scale image, and the pixels of the gray-scale image were counted to measure the total volume area of the hair swatches (fixed calibration). In order to take into consideration the influence of the three dimensional volume of the hair swatch, 8 pictures (images) were taken with a regular rotation of the hair swatch of 45 degrees each, and the values of the volume areas were averaged. The number of volume areas was then calculated as the effective volume.
• the measurement was carried out 3 times for one treated hair swatch. The same procedure was conducted with two more hair swatches to obtain 9 results in total for one composition, and the mean value was calculated for each composition. A lower score indicates that a better volume reduction effect was exerted.
• Table 1 shows that the composition according to Example 1 can provide less volume to hair as compared to the compositions according to Comparative Examples 1-3. Thus, the composition according to Example 1 can more effectively reduce the volume of hair, which means better volume reduction or volume control effects, than the compositions according to Comparative Examples 1-3.

Thus, the compositions according to Examples 1 and 2 can more effectively reduce the volume of hair, which means better volume reduction or volume control effects, than the composition according to Comparative Example 4.
• the results shown in Table 2 demonstrate that the use of 30% by weight or more of a volatile branched C l3 -i5 alkane oil relative to the total weight of the volatile oil(s) in the composition can provide better volume reduction or volume control effects than the composition according to Comparative Example 4 which includes less than 30% by weight of volatile branched Ci 3-i 5 alkane oil relative to the total weight of the volatile oil(s) in the composition.
