In this study, human hair follicles were maintained in a serum-free medium for up to 12 days, revealing detailed histological and ultrastructural changes that suggest possible catagen-like involution mechanisms.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

This study suggests that the patchy thickening and reddish discoloration in rabbit skin during the hair cycle may be due to large anagen-phase hair follicles compressing the dermis and increased blood vessels causing redness.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

This study compared the effects of direct heat perms and softening heat perms on hair, analyzing damage and morphological changes to understand their impact on hair fibers and provide foundational data for future research.

This study analyzed animal hairs from 18th-century burial sites in Mazamet, France, reporting distinct hair morphologies consistent with the use of common local animal furs such as goat, badger, cow, or horse, reflecting the modest socioeconomic status of the individuals interred.

In this study, Sox13 was identified as a novel marker for early hair follicle development and differentiation in mice, though it appears to be dispensable for overall epidermal and adnexal development.

In this study, researchers used a hypospadiac rat model to demonstrate abnormal genital development, similar to human penoscrotal hypospadias, highlighting the model's value for studying penile growth and differentiation.

In this study, Pomeranians with non-illness, generalized alopecia did not exhibit adrenal or pituitary abnormalities, suggesting a breed-specific hormonal pattern as a potential cause rather than a functional adrenal anomaly.

The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.

This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

This study developed a quantitative measure for scoring hair surface damage from SEM images and found it accurately classified hair damage caused by explosive blasts, similar to an existing classification system.

This study developed an automated image analysis framework for diagnosing hair disorders using trichoscopic images, reporting a Random Forest classifier as having an 86.67% accuracy in distinguishing between different scalp pathologies based on quantitative image features.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study found that using the "Khalgai" hair care products enriched with copper and zinc for 28 days led to increased hair density, diameter, and follicular unit count in women, indicating improved hair morphology.

This study found that human skin grafted onto certain immunodeficient mice resulted in proliferative scars with characteristics similar to human hypertrophic scars, suggesting these models may better represent the condition's natural history.

This study presents a new approach to automatically remove hair artifacts from dermoscopic images, which reportedly performed well compared to existing methods like DullRazor using the PH2 datasets.

This study found that increased atypical club hair observed in microscopic hair examinations may be characteristic of telogen effluvium compared to healthy individuals and diffuse alopecia areata patients.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

Image analysis can effectively identify changes in scalps affected by chemotherapy-induced hair loss.

Hair changes could indicate neurological diseases and help monitor treatment.

This study used multi-omics analysis to explore how wheat roots adapt to temperature stress, revealing that distinct hormonal signaling pathways are linked to iron homeostasis and drive root morphological changes, supporting the idea of an 'iron-dependent hormonal trade-off' model.

In this study, researchers observed distinct morphological differences in hair follicles of mutant mouse genotypes, influenced by the expression levels of keratin2-6g, which is essential for proper hair follicle development.

This study found that straight permed hair retains more weight than virgin hair during burning at higher temperatures, with distinct differences in morphological changes observed through thermal analysis and microscopy.

This study found that peroxide-rich plasma-activated water caused minimal morphological damage to hair, while nitrate-rich plasma-activated water induced significant damage, especially in porous hair types.

This study found that the differential expression of α- and β-keratin genes in feathers may explain their morphological and structural diversity, highlighting the chicken as a model for studying keratin-related diseases.

In this study, two cases of idiopathic hair casts in young girls responded well to 0.025% tretinoin lotion, with analyses suggesting an infrainfundibular origin for the lesions.

In this analysis, the authors examine how hairdressing techniques like thinning and micro-graduation can correct women's hairlines by softening optical contours and enhancing visual symmetry, emphasizing the relevance of individual factors such as morphology and stylistic expectations in selecting these non-medical approaches.

This study found that rebonding hair straightening treatments visibly damage the hair cuticle, causing surface erosion and cracks, as shown through Scanning Electron Microscopy analysis.

This study investigated the identity of Victor Vinnetou as Mbuyisa Makhubu using forensic facial comparison and DNA testing, but the findings were inconclusive, requiring further investigation.
