This study found that dopamine directly induces the catagen phase in human scalp hair follicles in vitro.

Glycerin in hand cream can cause allergic skin reactions.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

In this study, clozapine reduced suicide-related behaviors in a schizophrenia-like mouse model, but its effects on exploratory behavior were counteracted by the neurosteroid inhibitor finasteride.

In this study, ketoconazole treatment successfully cured a dog with erythematous epilation caused by Chaetomium globosum, with new hair growth observed 9 weeks later.

This study found that a newly constructed composite hydrogel dressing, made from silk fibroin, chitosan, and halloysite, promoted hair follicle neogenesis, angiogenesis tissue regeneration, and scar reduction.

This letter to the editor about prostaglandins in androgenetic alopecia in men and women reports no new research findings.

This study found that plasma rich in growth factors was a safe and more effective treatment for androgenetic alopecia than topical minoxidil, showing greater improvements in hair growth phases.

In this study, researchers identified 32 differentially expressed genes involved in androgenetic alopecia, with down-regulated genes associated with Wnt and TGF-beta signaling and up-regulated genes linked to oxidative stress pathways.

This study found that the distribution of mast cell prostaglandin d-synthase in the scalp spatially aligns with the pattern of androgenetic alopecia, suggesting a programmed vulnerability to hair loss.

This case study suggests that thermography could objectively assess pain severity in herpes zoster patients by correlating thermal images with reported pain intensity.

Spironolactone in anti-acne cream can cause allergic skin reactions in some people.

This study reports that mesenchymal stem cell-conditioned medium promoted dermal cell migration and proliferation, enhancing wound healing but not direct hair growth, in vitro and in adult mouse models.

This study found that topical cetirizine treatment significantly improved hair regrowth and patient satisfaction in male patients with androgenetic alopecia compared to a placebo, highlighting its potential role in treatment.

This study identified two distinct VDR gene mutations among Lebanese families with hereditary vitamin D-resistant rickets, noting varied treatment responses and promising outcomes despite severe phenotypes.

This study found that permanent wave treatment accelerates hair degradation after protease exposure, showing significant morphological differences compared to untreated hair and linked to damage from Alpha-helical region denaturation.

This study found that standardized scalp massages may help stabilize or regrow hair in individuals with androgenic alopecia, as perceived by the participants themselves.

This study found that pyramidal neural precursors best grew neurites on matrigel, while neural stem cells differentiated directionally on aligned fibrin, suggesting the importance of biomaterial selection for cell culture.

This study found that omeprazole can cause acquired generalized hypertrichosis by significantly increasing duodenal prostaglandin E2 synthesis, which is involved in hair growth regulation.

This study found that topical bimatoprost significantly improved eyelash growth in individuals with idiopathic and chemotherapy-induced eyelash hypotrichosis compared to a vehicle treatment.

This article discusses the creation of Alopecia Areata Uniform Protocols by the National Alopecia Areata Foundation to standardize clinical trials for alopecia areata treatments and reports no new results.

This review discusses the challenges in diagnosing polycystic ovarian syndrome due to its variable clinical features and emphasizes the need for early identification and intervention to prevent metabolic complications, but reports no new clinical results.

In this study, subcutaneous platelet-rich plasma injections improved hair density and histological markers of hair growth in hairless rats without causing local toxicity.

New method quickly and accurately measures dexpanthenol in hair products.

This study found that lymph vessel morphology and density in airways differed based on location and type of epithelium, with the highest density in the ciliated epithelium of the nasal passages and site-specific patterns apparent in both fetal and adult specimens.

The testes significantly contribute to vitamin D metabolism and may affect male reproductive health and conditions like hair loss.

In this study on dogs with yeast imbalances and dermatological signs, a protocol using chlorhexidine and Ophytrium products significantly reduced Malassezia pachydermatis counts and improved pruritus and irritation scores over 21 days, earning positive assessments from veterinarians and owners in most cases.

The study observed that consuming Pflorida soup, made from UV-exposed oyster mushrooms, maintained significant vitamin D levels comparable to recommended daily intake, despite storage and cooking reducing the vitamin content.

This study found that 12-week oral supplementation of Ageratum conyzoides extract significantly reduced hairline recession and affected prostaglandin levels in adults with hair loss, though hair density increases were not statistically significant, and no improvements were found in other hair loss measures compared to placebo.
