a monochromatic camera with a high-resolution chip, which combined with UVA light system, allows getting uniform imaging of the hair surface. Contrast and homogeneity were the
parameters related to hair nutrition. As more homogeneous and less contrasting are the hair fibres, more nourished is the hair. The measurements were performed after lock
equilibration (T0) and after the treatment (Tfinal), and the results were expressed in arbitrary units (AU).
Results ■ Assessment of the gloss effect After the treatment with a 1% oil blend conditioner, there was a significant increase in the shininess of the hair locks. 1% oil blend presented a 95.0% increase in
shine after the treatment. At the same time, the placebo presented a 46.2% increase. The comparison between the two products shows a statistically significant difference after the treatment: Assessment of the nourishing effect by hair contrast and homogeneity evaluation ■ Assessment of the hair homogeneity After the treatment, 1% oil blend conditioner presented a 7.2% increase in homogeneity. At the same time, the placebo conditioner
presented a 3.8% increase in shine. The comparison between the two products shows a statistically significant difference after the treatment:
■ Assessment of the hair contrast After the treatment, 1% oil blend conditioner presented a 75% decrease, in contrast, therefore the hair was more nourished. At the same time, the placebo conditioner
presented a 52.9% decrease. The comparison between the two products shows a statistically significant difference after the treatment: In conclusion, the oil blend increases hair shine and has a nourishing effect on the hair fibres.
Discussion and conclusions Due to the lower amount of lipids and the different distribution of these throughout the hair fibre, and their organisation within the Cell Membrane Complex (CMC), curly hair requires specific care and nutritional support. Ethomega is a natural botanical active
