[article]  inIFSCC MAGAZINE > Vol. 11, N° 1 (01-02-03/2008) . - p. 37-42 Titre : Coenzyme Q10 has anti-aging effects on human hair Type de document : texte imprimé Auteurs : Melanie Giesen, Auteur ; Thomas Welß, Auteur ; Erik Schulze zur Wiesche, Auteur ; Volker Scheunemann, Auteur ; Sabine Gruedl, Auteur ; Yasmin Oezkabakcioiglu, Auteur ; Elisabeth Poppe, Auteur ; Dirk Petersohn, Auteur Année de publication : 2008 Article en page(s) : p. 37-42 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Coenzyme  Q10'  'Follicule  de  cheveux'  Vieillissement  'Kératinocytes  externes  la  gaine  racine'  'Synthèse  kératine' Index. décimale : 668.5 Parfums et cosmétiques Résumé : Ubiquinones are the most widespread and therefore best investigated bioquinones. Due to their hydrophobic isoprenoid side chain, ubiquinones can be solubilized in organic solvents or lipids but are insoluble in water. Using a specific emulsifier system it has been possible to deliver positive effects to biological systems also from aqueous formulations. Ubiquinone-50, also referred to as coenzyme Q10, is well known in cosmetic science and especially in skin care because of its antioxidant activity. It is found in the membranes of peroxisomes, lysosomes, vesicles, the endoplasmic reticulum and notably in the inner membrane of the mitochondrion, where it is an important part of the electron transport chain. Using coenzyme Q10 in the proposed emulsifier system we could show that the molecule not only has relevance as an anti-aging bioactive in skin care but also has positive effects on the human hair follicle. The hair follicle is a complex mini organ and synthesis of hair keratin, the major component of hair fibers, is an essential prerequisite for the growth of strong and healthy hair. But like all biological systems the hair follicle, the biologically active part of the hair, also undergoes an aging process associated among other things with a decline in certain hair keratins. Due to this age-related shift in basic structural proteins of the hair shaft, mature hair often becomes fragile and difficult to manage. Therefore it is a challenge for cosmetic science to provide bioactives to fight age-related changes and maintain a youthful appearance of hair. Using cultivated hair follicle keratinocytes we identified coenzyme Q10 as a potent bioactive that stimulates the gene expression of different hair keratins, especially those which are reduced during aging processes in hair follicles. These results led us to investigate a shampoo and a tonic formulation enriched with coenzyme Q10 in a placebo-controlled panel study. In a left/right comparison a group of healthy volunteers older than 40 years of age applied the formulations daily for 4 days. Throughout the test period the gene expression of different hair keratins from plucked hair follicles was determined using quantitative polymerase chain reaction techniques. Subsequent statistical analysis revealed an increase in age-relevant hair keratins in human hair roots treated with coenzyme Q10, thus pointing out the striking benefits of coenzyme Q10 in hair care formulations. We conclude that coenzyme Q10 is an ideal ingredient for hair care formulations, providing anti-aging properties through activation of specific keratins aligned with the needs of mature hair.

Specific repair of aging hair keratin / Erik Schulze zur Wiesche in IFSCC MAGAZINE, Vol. 11, N° 4 (10-11-12/2008)

[article]  inIFSCC MAGAZINE > Vol. 11, N° 4 (10-11-12/2008) . - p. 317-320 Titre : Specific repair of aging hair keratin Type de document : texte imprimé Auteurs : Erik Schulze zur Wiesche, Auteur ; Thomas Gassenmeier, Auteur ; Detlef Fischer, Auteur ; Elisabeth Poppe, Auteur ; Petra Somfleth, Auteur ; Karola Schäfer, Auteur ; Andrea Körner, Auteur Année de publication : 2009 Article en page(s) : p. 317-320 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Hair  keratin  strengthening  Intermediate  filament  aging  simulation  restructuring Index. décimale : 668.5 Parfums et cosmétiques Résumé : A new method was developed to study aging effects onhuman hair keratin caused by shampooing, blow drying and sunlight. An automatic multiple process allowed reproducible simulation of the stress of approximately 100 Central European summer days in only 5 working days. Stress-strain measurements showed a significant weakening of the hair structure due to simulated aging effects. A new keratin active containing peptides identical to those in human hair was developed. The new keratin active penetrates deeply into the cortex cells, which was demonstrated by means of fluorescence microscopy. Aging damage was successfully prevented by strengthening the hair structure. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=3259 [article]

The smart salon concept : Individualized hair care & coloration products / Thomas Förster in SOFW JOURNAL, Vol. 145, N° 4 (04/2019)  

[article]  inSOFW JOURNAL > Vol. 145, N° 4 (04/2019) . - p. 4-10 Titre : The smart salon concept : Individualized hair care & coloration products Type de document : texte imprimé Auteurs : Thomas Förster, Auteur ; Georg Knübel, Auteur ; Lucile Bonnin, Auteur ; Thomas Schröder, Auteur ; Elisabeth Poppe, Auteur ; Matthias Schweinsberg, Auteur ; Jordan Katzarov, Auteur Année de publication : 2019 Article en page(s) : p. 4-10 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cheveux -- Soins et hygiène Formulation (Génie chimique) Marketing personnalisé shampooings Index. décimale : 668.5 Parfums et cosmétiques Résumé : Due to the individual hair-type diversity, it is nowadays challenging to satisfy all specific consumer needs. The first of its kind connected Smart Salon is combining: data driven hair analysis, a personal hair-consultation application and the formulation of a customized shampoo to address this challenge. In a first step, a wearable device composed of a near-infrared (NIR) and a visible light sensor, analyzes the hair fiber. The NIR analysis collects: the cysteic acid concentration and the water content. The actual color of the hair fiber is also measured with a visible light sensor. Quantification of the hair status is performed through analysis of chemometric data with the open-source software KNIME. In a second step, a visual evaluation e.g. previous treatment, length, thickness of the hair is performed and the user expectations e.g. volume, shine, smoothness etc. are collected in the consultation application. Finally, all gathered data are combined in a decision matrix to formulate a customized shampoo. The compact mixing machine uses a proprietary manufacturing process to produce a custom care solution. The connected ecosystem is combining innovative technologies with empirical R&D expertise to offer the best possible care solution. Automatization of the hair analysis enables a more targeted approach for individualized shampoo development.
