This study outlines a technique for hair transplantation that maintains natural hair flow and density by mimicking natural hair direction and angle without accelerating hair loss in the recipient area.

This review discusses the genetic basis of woolly hair syndrome and its potential link to heart disorders, highlighting recent discoveries of new molecular pathways and suggesting possible future treatment options.

In this study, researchers identified loss of function variants in the HR gene as likely causes of the distinct roaning hair coat seen in lykoi cats.

This article reviews previously reported cases of whisker hair in individuals who develop severe androgenic alopecia and offers a hypothesis concerning its eventual fate, without presenting new findings.

A man with Woolly Hair Syndrome had very curly, fragile hair, and doctors used a special scalp examination to diagnose him without invasive tests.

This review proposes a new approach for categorizing and diagnosing unruly hair forms, building on previous literature and clinical experience, without presenting new clinical results.

This study found that the curl in hair is due to the arrangement of different cell types, with shorter paracortical cells inside the curve and longer orthocortical cells outside.

In this study, coudability hairs were identified as a useful marker for assessing disease activity in patients with alopecia areata and may serve as an alternative to the hair-pull test.

This case study reports on an 11-year-old boy with woolly hair nevus, featuring twisted hair shafts and an abnormal hair cuticle, alongside epidermal nevi on his face and back.

This report describes a case of two sisters with kinky, tangled hair diagnosed using trichoscopic and microscopic methods; they were treated with topical minoxidil.

This case report describes a 5-year-old girl with trichorrhexis nodosa and highlights the presence of isolated curly hairs on her scalp despite hair loss over four months.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This report identified longitudinal grooves in the hair shafts of four children, diagnosing them with uncombable-hair syndrome.

Trichoscopy helped diagnose and treat a child's fungal scalp infection by spotting specific hair shapes.

This case report presents a patient with woolly hair and associated symptoms, including keratosis pilaris, nail dystrophy, increased interdental spaces, and recurrent bullous impetigo, observing a combination not previously reported.

Wearing a wig caused a woman's skin condition to worsen due to pressure from the wig's fasteners.

This study proposed that the tiger tail phenomenon in trichothiodystrophy hair is caused by regular undulations of hair fibers, altering the optical properties seen under polarized light.

This study found that mutant mice with the we/we wal/wal genotype exhibit significant defects in hair shaft structure and epidermis stratification, correlating with postnatal alopecia symptoms.

This study suggests that topical minoxidil may be a promising treatment for isolated autosomal recessive woolly hair due to LIPH mutations, although effective treatments are not yet established.

Corkscrew hair may be a new sign for quickly diagnosing scalp fungus in black children.

This article discusses the rare condition of hypertrichosis, highlighting a case of a 10-year-old boy with congenital hair growth and emphasizing the need for patient support due to limited treatment options.

This article reviews the condition plica neuropathica, including its manifestations, potential causes, and treatment, but it does not provide new clinical findings.

This study assessed hair whorl characteristics in domestic dogs and found that simple whorls predominate, with tufted whorls more common in specific regions like elbows and chests, influenced by factors such as coat traits and source.

This study suggested that differences in hair follicle development, indicated by the frequency of underdeveloped hairs, significantly contribute to the variation in hair loss severity among Japanese individuals with the LIPH c.736T>A mutation.

This report suggests that peripilar hair casts, potentially linked to modern hair styling or mild trichotillomania, may be more prevalent than currently reported.

Mammalian hair scales change from smooth to wavy due to friction.

This study found that using an overnight peel treatment for 3 months increased wrinkle spacing, leading to an average reduction in wrinkles of 39% in 67% of participants.

In this study, a 3-year-old Japanese child with autosomal recessive woolly hair was found to have a distinctive irregular and rough cuticle on the hair shaft, along with a homozygous pathogenic LIPH variant, suggesting a critical role for genetic analysis in understanding rare hair conditions.

This case report documents the first instance of acquired uncombable hair syndrome in a 39-year-old woman, characterized by diffuse alopecia and minimal upper lip hirsutism.

This study introduces the multiple papillary centres model, offering a new explanation for hair twisting by combining known hair morphology features with differential growth rates caused by dermal papillae.
