This report describes a child and his father with hereditary hypotrichosis simplex, an uncommon isolated form of hair loss, with no other ectodermal or systemic abnormalities noted.

Hair follicle dermal stem cells help control hair growth timing by regulating signals at the hair germ–dermal papilla interface.

This source explains that Equine Cushing’s disease, or PPID, in horses is due to the degeneration of brain cells producing dopamine, leading to elevated cortisol levels and characteristic symptoms; it outlines diagnosis methods and emphasizes life-long pergolide treatment to manage the condition.

This study found that Arabidopsis thaliana mutants with altered AtRBOHC/RHD2 enzyme function showed abnormal protein regulation linked to increased drought sensitivity due to disrupted plasma membrane protein balance and cytoskeleton changes, as revealed through proteomic analysis and advanced microscopy.

In this case study, DDS treatment for LABD was complicated by hemolytic anemia and alopecia, suggesting the need for careful monitoring of these potential side effects.

This study reports a rare cluster of four patients with ectodermal dysplasia, highlighting its typical dental and dermatological manifestations and the necessity of multidisciplinary management.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.

This review covers the pathophysiology, diagnosis, and treatment of nonclassic congenital adrenal hyperplasia due to P450c21, but it reports no new clinical results.

This case report describes a novel mutation in the CDH3 gene in an 11-year-old Iranian boy with sparse scalp hair and macular dystrophy, leading to altered P-cadherin synthesis.

Hydroxychloroquine effectively treated twenty-nail dystrophy in a patient with alopecia areata.

This case report describes an instance of autosomal recessive uncombable hair syndrome caused by maternal uniparental disomy of chromosome 1.

In this cross-sectional study, researchers observed that patients with hidradenitis suppurativa, particularly women, had lower 2D:4D finger length ratios compared to healthy controls, suggesting a potential link to prenatal androgen exposure and disease severity, though further prospective research is needed to confirm this hormonal impact.

A 4-year-old girl had a rare hair disorder affecting only part of her scalp.

Patients with Focal Dermal Hypoplasia often experience skin, nail, hair, and bone issues, and may benefit from calcium and vitamin D supplements.

This study found that hidradenitis suppurativa significantly impacts patients' sexuality, with many experiencing fear of rejection, perceived unattractiveness, and negative effects on relationships and sexual activity.

This study explored the effects of DPP, a 15-PGDH inhibitor, on human follicle dermal papilla cells damaged by dihydrotestosterone and observed that DPP enhanced wound healing, reduced reactive oxygen species, and increased hair growth in ex vivo human hair follicle cultures.

Haloperidol decanoate can cause alopecia areata.

This report describes two patients with ichthyosis linearis circumflexa exhibiting symptoms resembling Netherton's disease, noting multiple hair shaft defects and discussing a possible connection to aminoaciduria.

This case series reported that three pediatric patients with hidradenitis suppurativa showed decreased frequency and severity of disease flares after treatment with oral finasteride, with no significant adverse effects.

The researchers reported that inhibiting 11β-HSD1 activity in human dermal papilla cells may reduce the negative effects of glucocorticoids on hair growth, suggesting potential treatment for stress-related hair loss.

This study found that 9% of tested patients had positive patch test reactions linked to hair care products, with most reactions clinically relevant and commonly involving allergens like p-phenylenediamine.

This study reports a case of GGCX syndrome in a 55-year-old Japanese male, characterized by PXE-like symptoms and coagulation deficiency, with an unreported phenotype of possible spinocerebellar degeneration.

This study found that concentrations of haloperidol and its metabolite in human scalp hair significantly correlated with the daily dose and plasma trough levels in patients taking haloperidol.

This study observed that CDH3-related congenital hypotrichosis with juvenile macular dystrophy presents with childhood-onset progressive chorioretinal atrophy and universally thin and sparse scalp hair.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

In this study, a comprehensive treatment approach involving multiple therapies was found to play a crucial role in managing hidradenitis suppurativa in patients with intellectual and developmental disorders despite practical challenges.

In this study, trypsin digestion was found to be a faster and more efficient method than the explant technique for extracting bulge-derived keratinocytes from adult scalp biopsies.

This study found that combining human dermal papilla fibroblasts with hair matrix cells formed organoids capable of limited hair follicle development in ex vivo skin, but not fully formed hair follicles.
