This study found that all-trans retinoic acid (ATRA) negatively affects hair growth by reducing goat dermal papilla cell viability and growth factor expression.

This study presents a new classification of adult human scalp hair patterns based on high-resolution photographs, which may assist hair restoration surgeons and dermatologists in determining appropriate punch size for follicular unit extraction.

This review discusses the complex correlation between cellular senescence and PCOS, emphasizing senescence markers, mechanisms, and potential anti-senescence therapies, but reports no new clinical results.

In this rat study, subcutaneous injections of hydrogen peroxide and cumene hydroperoxide appeared to completely prevent chemotherapy-induced hair loss by inducing cell cycle arrest, suggesting a novel approach to help cancer patients maintain their quality of life during treatment.

This study investigated how 2D and 3D cell culturing methods influence hair follicle morphogenesis, finding that 3D cultures responded more expectedly to minoxidil while 2D cultures reacted better to DHT treatment, challenging the assumption that 3D cultures are always superior.

In this study, clinicians are advised to perform trichography regularly on Pomeranians with HCA, as significant hair abnormalities, especially TN, may affect hair quality; further research is needed to understand the underlying mechanisms and treatment options.

In this study, researchers cloned a two-year-old Pomeranian with Alopecia X after its accidental death and found that the cloned dog developed the same hair lesions at the same age, suggesting the condition is genetically driven rather than environmentally influenced.

This study found that in vivo and in vitro, citric acid metabolism through the CS-CA axis suppressed hair growth and induced inflammation and cell apoptosis in hair follicles, suggesting it as a potential therapeutic target.

This case report suggests that Malarone® may cause acute pancreatitis and alopecia in dogs, highlighting the need for careful monitoring of adverse reactions when using this drug in canine treatment.

This study documented that symmetrical, noninflammatory alopecia in schipperkes is associated with hormonal abnormalities and hair cycle arrest, resembling Alopecia X clinically and histologically.

This article reviews the causes and diagnostic approaches for feline alopecia, emphasizing the importance of distinguishing between self-inflicted and spontaneous hair loss, but reports no new results.

This study developed a testosterone propionate-induced C57BL/6 mouse model of androgenetic alopecia, demonstrating that high-dose, prolonged testosterone administration inhibited hair regrowth and mirrored human AGA pathology, providing a useful platform for studying hair loss mechanisms and testing therapies targeting the Wnt/β-catenin pathway.

This research examined krill oil's effects on benign prostatic hyperplasia and found that it inhibited the growth of prostate cells in vitro and reduced prostate size and weight in a BPH rat model, suggesting potential as a prophylactic or therapeutic agent for BPH.

Elevated luteinizing hormone contributes to female-pattern hair loss, and blocking certain channels may help prevent it.

This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.

This study identified the transcription factor Elf5 as a novel regulator of keratinocyte proliferation and differentiation in skin, with expression elevated in stem/progenitor cell populations, suggesting its potential role in determining cell fate during skin and hair development.

This source describes the first successful use of a deslorelin acetate implant to treat alopecia X in a neutered female dog, achieving profuse hair regrowth in 9 months, suggesting an uncomplicated and cost-effective alternative after melatonin failure.

This study observed that treating basal and squamous cell carcinoma cells with platelet-rich fibrin significantly reduced cell viability and increased apoptosis-associated gene expression, suggesting potential use as adjunctive therapy for localized nonmelanoma skin cancers.

This study reports that the β-catenin inhibitor tegatrabetan reduced hair growth and hair follicle numbers in mice, suggesting its potential as a model for developing new hair growth materials.

In this study, Iris germanica L. rhizome-derived exosomes were found to reduce oxidative stress, enhance antioxidant enzyme transcription, and restore cellular function in human epidermal keratinocytes, suggesting potential protective effects against oxidative-stress-induced skin damage.

The study found that safflower extract may help protect human follicle dermal papilla cells from cisplatin-induced damage, suggesting its potential as an adjuvant in chemotherapy to mitigate hair follicle cell damage.

This study found that apocynin restored collagen production, reduced DNA damage and senescence, and protected skin stem cells from aging in UVB-exposed human keratinocytes.

This study found that apocynin restored COL17A1 expression in human keratinocytes and reduced UVB-induced cellular senescence, DNA damage, and cell cycle arrest.

In this study, stress hormone CRF was found to inhibit hair growth, suggesting that the HPA axis is functional in human dermal papilla cells and contributes to hair loss under stress conditions.

This study showed that the stress hormone CRF inhibits hair growth and induces hair loss by affecting both the proliferation of human dermal papilla cells and hair follicle function.

Ovol2 is essential for normal skin and hair regeneration.

This article discusses the diagnostic approach to focal alopecia in dogs, focusing on distinguishing between pruritic skin disease and inflammatory or non-inflammatory causes; it presents no new experimental results.

Some medications and supplements can cause serious side effects, including hair loss, heart rhythm problems, liver injury, and other health issues.

This study found that microneedling induced nearly complete hair regrowth in two Pomeranians with alopecia X, suggesting it may be a promising alternative treatment for similar hair cycle arrest disorders.

Deslorelin can help regrow hair in most intact male dogs with alopecia.
