In this study using a mouse model, RIPK1 inhibitors were found to delay the onset of alopecia areata, reduce immune cell numbers in affected skin, and increase hair length, indicating a potential therapeutic role in preventing alopecia areata.

This case report describes a 22-year-old Asian man with erosive pustular dermatosis of the scalp, whose lesions improved after treatment with topical tacrolimus and oral isotretinoin.

Hhip-Cre effectively targets dermal papilla cells for gene manipulation in hair biology.

This study found that proton minibeam radiotherapy demonstrated a potential tissue-sparing effect in epidermis models by spatially confining DNA damage, suggesting reduced side effects in radiotherapy.

This case report details a unique instance of pityriasis rubra pilaris affecting only the scalp, highlighting novel trichoscopic features and emphasizing the importance of recognizing this rare presentation for improved diagnosis and treatment.

This study found variation in erythema induction across skin types, suggesting different SSR dose responses and highlighting a potential model for tailoring anti-inflammatory treatments.

This study found that a rosemary extract hair tonic at concentrations up to 15% effectively promotes hair growth in male Wistar rats, achieving longer and thicker hair compared to minoxidil 2%, and causing fewer side effects.

This study reports that in mice, retinoic acid mediates communication between hair follicle and melanocyte stem cells by influencing differentiation in their shared niche during hair regeneration.

This report describes a rare case of kerion in a 6-year-old boy in Ireland, treated with oral Itraconazole and steroids, highlighting the condition's unusual occurrence in the region.

Krt6a-Cre transgenic mice help study gene effects on hair follicle development and tumor suppression.

This case report describes a severe form of HIV-associated pityriasis rubra pilaris in a dark-skinned woman that improved rapidly and sustainably with combination antiretroviral therapy, despite atypical presentation without significant erythroderma.

In this study, nandrolone decanoate treatment in rats caused persistent diestrus and altered steroid receptor expression and sex hormones, especially at higher doses, with partial reversibility at lower doses over time.

Baricitinib helps regrow hair in teens with severe alopecia areata.

This study found that finasteride effectively inhibits the enzymatic activity of human steroid 5 alpha reductase type II in newly established CHO cell lines.

This study found that clipping is the most effective method for anagen synchronization in adult rat models to mimic chemotherapy-induced alopecia, producing robust anagen phases without causing skin trauma.

This study found that finasteride reduced impulsivity in a rat model of pramipexole-induced probability discounting, possibly by normalizing D3 receptor expression in the nucleus accumbens.

In this study, Rosa rugosa water extract improved hair length and thickness in a mouse model of DHT-induced alopecia by enhancing the expression of hair growth-promoting factors while inhibiting growth-suppressive proteins, suggesting its potential as a natural therapy for hair loss prevention.

In this study, researchers evaluated CS12192, a selective JAK3 inhibitor, in an alopecia areata mouse model and found it reversed hair growth inhibition comparably to baricitinib, with better safety and similar immune-modulating mechanisms.

A rare skin condition causes red and dark patches on the face and limbs.

In this laboratory study on rabbits, the researchers observed that both FET and FHE fractions improved hair length and weight, but minoxidil still led to better results, highlighting the comparative effects of different treatments on hair growth over 28 days.

This study reported that rice bran oil from the Thai rice variety BB4CMU showed potential in promoting melanin production and inhibiting steroid 5α-reductase, suggesting a natural option for hair revitalization.

In an animal study, researchers found that a hair tonic containing a 1:1 ratio of kelor and rambutan leaf extracts led to similar hair growth in rabbits compared to a minoxidil control, with average hair lengths of 3 cm versus 2.025 cm, respectively.

This study found that in patients with severe alopecia areata, those who responded early to baricitinib treatment typically had a lower baseline Severity of Alopecia Tool score, shorter disease duration, and higher erythrocyte sedimentation rate, suggesting these factors may predict therapeutic success.

This study developed and tested a new algorithm for analyzing coat and skin coloration in laboratory animals, using digital images and hierarchical color clustering, which effectively quantified color proportions and tracked changes over time without specialized software.

In this case report, a 37-year-old patient with APECED showed significant clinical improvement, including hair regrowth and resolution of skin issues, after 11 months of treatment with ruxolitinib, highlighting the potential of JAK inhibitors in managing this complex autoimmune disease.

In this study, TCDD administered to male rats down-regulated EGF receptor in liver plasma membranes and increased protein kinase activity, suggesting EGF receptor–mediated toxicological effects.

This study found that repeated finasteride administration in male Wistar rats led to increased depression-like behavior, suggesting an animal model for investigating finasteride's neuropsychiatric effects is viable.

This case study reports on a rare form of vitamin D resistant rickets in a 37-year-old male, highlighting the condition's clinical features and the necessity for a thorough understanding of calcium and vitamin D metabolism in the diagnosis and management of metabolic bone diseases.

In this study, retinoic acid treatments induced glandular and feather formation in embryos by altering positional values and activating specific retinoic acid nuclear receptor gene expression.
