Red era: Dyeing yak hair fibres red with in situ generated silver nanoparticles using silver nitrate and a flavonoid‐containing plant extract

open access: yesColoration Technology, EarlyView.
Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...

Delipidisation of wool fibres and the subsequent beneficial properties of delipidised wool fibres

open access: yesColoration Technology, EarlyView.
Abstract Wool fibres are complex matrices of proteins and fatty acids/lipids found both internally and externally. 18‐methyleicosanoic acid (18‐MEA) is covalently bound to the surface of the fibre via a thio‐ester link, and is considered one of the most important lipids as it is responsible for the hydrophobic properties of wool fibres.

In‐vivo pilot study to assess a new plant‐based cosmetic formulation containing Ziziphus joazeiro bark extract and Apium graveolens seed extract for the improvement of dandruff while enhancing scalp microbiome balance and barrier function in subjects with oily to dry sensitive scalps

open access: yesInternational Journal of Cosmetic Science, EarlyView.
This study comprising dermatological as well as microbiome analysis indicates that mild‐to‐moderate dandruff symptoms can successfully be reduced with a plant‐based shampoo by restoring the bacterial scalp microbiome balance, suggesting a ‘microbiome‐friendly’ formulation tolerated excellently for oily scalp and sensitive scalp.

Cyclic combing of untreated and bleached human hair: Analysis of the time‐dependent breakage of hair through recording the formation of fibre fragments

open access: yesInternational Journal of Cosmetic Science, EarlyView.
One important aspect of daily hair grooming routines is whether, after combing, conspicuous numbers of broken hairs are observed. Machine‐based cyclic combing of hair tresses serves as a good indicator for early hair breakage and as a suitable measure to determine the effect of an ingredient/product/process on hair ‘strength’.

Perceptions of female age, health and attractiveness vary with systematic hair manipulations

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Two experiments were conducted to study how lay individuals evaluate systematic changes in female head hair. The results showed that participants tended to rate high‐shine hair more favourably than lower‐shine hair. When combining shine with alignment and volume, straight‐aligned hair with high shine and low volume was generally perceived as more ...

Reinventing henna: Enzyme‐catalysed colour release from stabilized Lawsonia inermis L. extracts

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The instability and reduced dyeing performance of a cosmetic formulation containing 2‐hydroxy‐1,4‐naphthoquinone (lawsone), derived from Lawsonia inermis L., is demonstrated in comparison to a novel two‐component system. This system comprises one formulation with naturally occurring lawsone precursors and a second containing a specific hydrolase ...

Electrokinetic analysis reveals common conditioner ingredient interactions with human hair

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Novel electrokinetic analysis reveals how cationic surfactant deposition on hair is influenced by chain length and counterion mobility. Longer‐chain surfactants show superior adsorption through enhanced van der Waals interactions, while chloride counterions enable stronger electrostatic interactions.

Establishment and validation of a hair fall atlas for Chinese men based on trichoscopy

open access: yesInternational Journal of Cosmetic Science, EarlyView.
A new hair fall atlas with 7 scales is established and validated and ready to publish as a new methodology. We observed good consistency between the dermatologists' grading (PCC >0.8), and a strong correlation shown between clinical scores and hair fall attributes based on image analysis (|p| > 0.8).

Commercial clays in cosmetic formulations for hair care: Characterization and application to improve the mechanical properties of hair fibre

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The shampoo and conditioner bar formulations enhanced hair gloss, promoting softness, improved cuticle alignment, and effective protection of hair shafts against external aggressors. Findings from mechanical properties measurements indicate that the clay‐containing formulations enhance the mechanical strength of hair, contributing to stronger and more ...
