This study presents the first reported case of woolly hair nevus appearing during adolescence, with significant improvement observed 5 years later and structural changes in the hair documented.

This study suggests that chemical methods can reveal subtle differences in scalp hair color variability across populations and emphasizes the need for enhanced understanding of hair fiber curvature.

The study found that certain hair care practices, such as wearing cornrows and infrequent use of hair oil, were significantly associated with traction alopecia and seborrheic dermatitis in African American girls, but no significant link was observed with tinea capitis.

This study reported that the treatment of hair with glyoxylic acid straighteners causes major conformational changes within the hair fiber due to interactions between carbonyl and keratin components.

In this commentary, the authors discuss the challenges and proposals for responsibly translating regenerative therapies into clinical practice, emphasizing the need for patient education, quality control, and real-world evidence to validate these therapies and address ongoing misinformation in the field.

Mutations in the Sgk3 gene cause fuzzy hair in mice.

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 letter to the editor discusses an observed case of hair repigmentation linked with etretinate therapy but reports no new research findings.

Pseudofolliculitis cutis causes painful skin bumps and needs proper shaving and treatments to manage.

This review discusses cases of ringworm of the scalp, highlighting the potential for spontaneous cure when the infection is caused by an organism pathogenic to animals, and reports no new clinical results.

This study reports a case where a 13-year-old boy's hair texture changed to resemble his early childhood hair after regrowth from alopecia areata, with potential causes remaining uncertain.

This study identified a new mutation in SELH/Bc mice causing distinctive whisker and body hair abnormalities, mapped near the type I keratin cluster on chromosome 11.

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.

FUE can be successfully done on African-American hair by using larger punch tools and careful techniques to reduce hair damage.

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.

This report describes a rare case of acquired eyelash trichomegaly in a 16-year-old female with systemic lupus erythematosus, accompanied by diffuse hair loss and "lupus hairs" on the scalp.

Using minoxidil and tretinoin on the skin, along with oral vitamin D, improved hair thickness and density in two girls with woolly hair.

This case report describes a patient with lichen nitidus whose lesions improved following treatment with oral astemizole and topical steroids, although spontaneous resolution remains a possibility.

This review discusses the genetic origins of autosomal recessive woolly hair with hypotrichosis and reports no clinical results; it highlights the link to homozygous variants in the K25 keratin gene.

This report documents a rare case of familial eyelash trichomegaly and synophrys in three siblings, with one sister also having loose anagen hair syndrome, an unreported association.

This study identified specific miRNAs associated with hair follicle development in chicken embryos, highlighting miR-1623's involvement in regulating WNT4 and contributing to hair follicle cell growth.

This article discusses pseudofolliculitis barbae but reports no new research findings.

This letter to the editor describes a case of acquired progressive kinking of the hair in a Korean female adolescent, but no new research findings are reported.

This review examines the androgen-dependent subtype of acquired progressive kinking of the hair and suggests it may be an early indicator of androgenetic alopecia, emphasizing the importance of distinguishing between subtypes for clinical decisions.

In this case study from King Fahad University Hospital, an 11-month-old Saudi boy with a history of short, non-growing hair was diagnosed with autosomal recessive woolly hair/hypotrichosis, attributed to a homozygous mutation in the LIPH gene.

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.

In this case study, a 19-month-old infant with palmoplantar keratoderma and nail dystrophy was found to have a desmoplakin gene mutation, leading to cardiomyopathy by age 7, illustrating diagnostic challenges and the potential link between skin, dental, and cardiac anomalies.

This review discusses the potential risks of formaldehyde in hair keratin treatments like Brazilian blow-dry, and reports no new clinical results; it emphasizes the need for greater safety assessments including occupational exposure.

This case report describes a 19-year-old female with systemic lupus erythematosus who exhibited eyelash trichomegaly, a rare disorder involving changes in eyelash characteristics, alongside diffuse alopecia.

This study used single-cell RNA sequencing to characterize 19 distinct cell populations in sheep hair follicles, uncovering differentiation signatures and intercellular communication that may influence wool curvature and sheep breeding.
