This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This study found that the optimal characteristics for ulin seed oil extraction are fresh, mature, and resinous seeds, and that FTIR spectrophotometry with PCA can effectively detect adulteration of the oil, particularly at certain wavenumbers like 1745 cm⁻¹.

This study found that ATR-FTIR spectroscopy combined with machine learning effectively differentiated alopecia areata patients from healthy controls with an AUC of 0.85, and also showed promise in predicting treatment response, particularly through alterations in the Amide I band.

This study used phytochemical screening and FTIR spectroscopy with PCA to reveal slight chemical differences between two varieties of Eclipta alba, providing a method for their effective discrimination.

PEVs effectively deliver minoxidil through skin.

This study developed a spectrophotometric method to determine minoxidil in pharmaceuticals, creating a highly sensitive, simple, and cost-effective approach using a synthesized charge transfer complex with a notable absorption peak at 505 nm.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

In this study, extracts from Chenopodium quinoa, Glycine max, and Malpighia emarginata demonstrated stability, low toxicity, and effective cleaning potential as surfactants in shampoo formulations, showing performance similar to or better than commercial shampoos in terms of surface and interfacial tension and sebum removal.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study reports that hair oil formulations using Arnica montana in castor and mustard oil bases showed effective results in quality and quantitative analysis through UV visible spectrophotometer, FTIR, and HPTLC testing methods.

This study found that 1,4-n-butylene dimaleate can restore the mechanical properties of reduced hair by reconnecting disulfide bonds and improving the hair's structural integrity using a thiol-Michael click reaction, compared to untreated reduced hair.

This study developed chemical fingerprints to differentiate Eclipta prostrata and Wedelia calendulacea, two plants often confused and adulterated in the Indian herbal market, identifying distinct chemical profiles that can prevent such adulteration.

This study found that a subfraction from Sansevieria trifasciata showed higher hair growth activity than other fractions in tests on rabbits.

This study found that certain pyrazole derivatives may serve as effective 5α-reductase inhibitors with potential use in the treatment of androgenetic alopecia, based on molecular docking analyses.

This study evaluated the protective effects of a hair conditioner containing rice derivatives on natural Caucasian hair using various analysis methods and found that the conditioner, especially with rice germ oil GX-N, effectively improved hair properties even under stress conditions like irradiation.

Lower acetylation makes chitin nanofibers thinner and more suitable for various uses.

Hair removal methods damage the skin barrier and affect substance penetration.

This study indicates potential differences in the hair spectra of individuals with mood disorders, suggesting a promising, yet preliminary, method for noninvasive prediagnosis.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

This study found that monoethanolamine-based hair color formulations caused significantly more damage to hair than ammonia-based formulations, especially at high concentrations.

A new, quick method accurately detects minoxidil in drugs and cosmetics.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.

In this study, researchers developed and tested an herbal antidandruff shampoo using plant extracts like neem, fenugreek seed, aloe vera, and clove, demonstrating antibacterial and antifungal activity against common scalp microbes and offering a potential natural alternative for dandruff treatment.
