StatistiqueIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Increasing hair fullness is a global unmet need for many men and women. An approach to the problem is to decrease hair fall or shedding by reducing scalp stratum corneum oxidation and barrier damage to increase hair retention. This study evaluated a combination of functional antioxidants and barrier-enhancing cosmetic ingredients to improve scalp condition thereby enabling stronger hair anchorage and longer retention.
- Methods : Male and female subjects with normal scalp condition and self-perceived hair thinning participated in a 24-week, double-blind, placebo-controlled, randomized clinical study assessing either a regimen of treatment shampoo and leave-on treatment containing functional antioxidant and barrier-enhancing agents or an identical placebo chassis shampoo control. The functional ingredients were piroctone olamine, zinc pyrithione, zinc carbonate, niacinamide, panthenol and caffeine. At baseline and after 8, 16 and 24 weeks of product use, several measurements were taken: hair shedding, total hair count (by phototrichogram), hair samples, TEWL and evaluation of biomarkers of scalp and hair conditions. Subjects also completed self-assessment questionnaires.
- Results : Statistically significant effects for functional ingredient-containing treatment regimen versus a placebo control shampoo formulation were observed for reduced hair shedding, increased total hair count, reduced TEWL and improvement in scalp biomarker values. Subjects also noticed these improvements assessed via self-assessment questionnaires.
- Conclusions : These results establish that the use of functional antioxidant and barrier-enhancing agents to further improve scalp condition can enable a reduction in hair shedding and thus an increase in perceived hair fullness. The underlying improvements in scalp condition suggest the hair benefits were achieved as a result of improved scalp skin barrier and scalp condition leading to a viable preventative approach for hair thinning.Note de contenu : - MATERIALS AND METHODS : Hair products - Study design and subjects

shampooingsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Increasing scalp hair fullness is a global unmet consumer need. An approach to decrease hair shedding by reducing scalp stratum corneum oxidation via a combination of antioxidant and barrier-enhancing technologies has been previously demonstrated. The purpose of this study was to test the effectiveness of the individual antioxidant piroctone olamine in two different product forms (shampoo or leave-on product) for activity to improve hair retention.
- Methods : Female subjects with self-perceived hair thinning participated in an 8-week, double-blind, placebo-controlled, randomized clinical study to evaluate either a piroctone olamine (PO) containing shampoo or a PO containing leave on treatment, each relative to their corresponding placebo formulation Too many periods. Results for phototrichograms, TEWL, and biomarker analysis of scalp condition for the shampoo treatments are discussed. Phototrichogram results are shared for the assessment of the leave on treatment.
- Results : Statistically significant increases in hair amount were observed by phototrichogram after use of both PO-containing products versus placebo formulations. The PO shampoo treatment also significantly decreased oxidative stress on the hair and scalp, and improved scalp condition as assessed by TEWL and scalp biomarker values.
- Conclusion : These results illustrate the effectiveness of a cosmetic antioxidant to improve scalp condition thereby improving hair retention. The observed improvements in scalp condition are consistent with previous reports with other antioxidant technologies and suggest that the hair retention effect was achieved by preventing oxidative damage to the scalp.Note de contenu : - MATERIALS AND METHODS : Study design and subjects - Study design and sample size for assessment of the shampoo treatments - Study design and sample size for assessment of the leave-on treatments - Study procedures - Statistics

StatistiqueIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Malassezia furfur is a lipophilic and dermatological pathogenic yeast, which normally exists on human skin, and causes tinea versicolor, seborrhoeic dermatitis, and atopic dermatitis, especially on human scalp. The multi-herb extraction, VGP, which consists of Vitex trifolia fruit, Gentiana scabra, and Polygonum multiflorum root extract was used to study its effect of anti-inflammation, controlling sebum and dandruff on scalp care. Results showed that on the model of NHEK and THP1 cell inflammation induced by Malassezia furfur, VGP can inhibit the expression of interleukin 6 (IL-6), prostaglandin E2 (PGE-2), monocyte chemoattractant protein 1 (MCP-1) and interleukin 1β (IL-1β) in a dose-dependent manner under 0.01% to 0.125% concentration. On the inflammatory model of 3D reconstructed skin induced by H2O2, VGP significantly improved the cell viability and skin structure, and reduced the production of interleukin 8 (IL-8), PGE-2, and leukotriene B4 (LTB4). During 4 week’s treatment with test shampoo containing 0.5% VGP thrice a week on 16 subjects met with different symptoms, VGP reduced the sebum content and TEWL, improved the redness, itching and dandruff on human scalp skin. Therefore, as a natural active ingredient VGP can play a role in scalp care and skin care by targeting inflammation.

HoméostasieL'homéostasie (du grec "hómoios", "similaire", et "stásis", "stabilité, action de se tenir debout") est la capacité que peut avoir un système quelconque (ouvert ou fermé) à conserver son équilibre de fonctionnement en dépit des contraintes qui lui sont extérieures.
L'homéostasie est la maintenance de l'ensemble des paramètres physico-chimiques de l'organisme qui doivent rester relativement constants (glycémie, température, taux de sel dans le sang, etc.).

Sensibilité cutanéeIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Sensitive scalp is an extension of the concept of sensitive facial skin, and is associated with dry skin, reactivity to climatic/environmental factors, and topical agents. Vitalab’s scientists have harnessed the power of the medicinal plant Portulaca oleracea, developing an ingredient clinically tested for its efficacy to soothe the skin, reduce the perception of itch intensity for both skin and scalp, and restore the skin barrier function. The multifunctional ingredient improved cellular ability to scavenge free radicals, while reducing the release of pro-inflammatory messengers, helping to relieve sensitive-prone skin and scalp.
