| Résumé : |
The prolonged use of heat styling devices may lead to cumulative effects on the hair fibre. These involve various physical and chemical changes of hair cuticle and cortex structure that seem significantly linked to a gradual protein thermal denaturation after exposure to high temperatures. The worsening of hair sensory attributesland hair breakage increase caused by cuticle and cortex layers degradation, are amongst the long-term damages of heat hairstyling : The aim of the present study was to evaluate the potential use of two Kelisema's protein hydrolysates derived from sesame seeds (Kelipro Sesame, INCI : Hydrolyzed Sesame Protein) and hemp seeds (Kelihemp, INCI : Hydrolyzed Cannabis Sativa Seed Extract) as hair heat protectants. Simulating a customer hair care practice, virgin hair tresses were pre-treated with protein hydrolysates aqueous solutions and subjected to repetitive thermal stress cycles using a straightening iron. Single-fibre tensile testing was performed to assess hair damage ; dry-state hair break stress and hair diameter change were evaluated. |

- OBJECTIVE :
- MATERIALS AND METHODS : Protein hydrolysates and test solutions - Hair samples - Thermal treatment of hair - Hair strength evaluation
- Fig. 1. Hair diameter change. Data are reported as % change respect to virgin - hair. Statistically significant vs virgin - hair (p<0.05)
- Fig. 2. Hair strenght evaluation. data are normallised to hair diameter and expressed as % F/d (mN/µm) change respect to virgin - hair (100%). One-way ANOVA test resulted statistically significant (<0.05). Statistically significant vs virgin - hair (p<0.03)
- Fig. 3. Hair substantivity on virgin hair. Data reported on the graph are expressed after subtraction on control values |
