In this study, two patients with long-term total parenteral nutrition and no biotin intake experienced hair regrowth after biotin supplementation, suggesting biotin deficiency can lead to alopecia.

In this case report, a 22-year-old female was diagnosed with follicular Dowling-Degos disease based on clinical and histological findings, with symptoms including skin lesions confined to hair follicles. The report emphasizes the importance of differentiating this rare variant from similar conditions for proper management.

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

In this laboratory study on mice, researchers found that both platelet-rich plasma and salmon DNA serum promoted wound healing, with platelet-rich plasma providing faster results due to its bioactive growth factors.

This study found that platelet-rich plasma therapy may improve symptoms and quality of life in adults with moderate to severe atopic dermatitis, although standardized protocols for its preparation need further study.

This study found that certain genetic variations in the OPN gene may be linked to atopic dermatitis and a higher prevalence of asthma in Caucasians.

This study found that platelet-rich plasma microneedles promoted hair regrowth in mice by facilitating angiogenesis and cell proliferation, showing promise for a minimally invasive hair regeneration treatment.

This report describes two cases where lichen planopilaris may have compromised the hair follicles in both donor and recipient areas following follicular unit transplantation.

This review discusses the diagnosis, management, and treatment options for peripheral arterial disease and does not report new clinical findings; the authors emphasize the need for early diagnosis and comprehensive management.

This study demonstrated that injecting reconstructed dermal papilla-like tissues in mice led to new hair growth, suggesting potential future applications in hair transplantation and baldness treatment.

This lecture presented the author's experience with over 250 PRP treatments on more than 150 patients in esthetic dermatology, highlighting PRP's use of autologous platelets to potentially accelerate healing through normal pathways.

This study investigated the use of dissolving microneedle patches to improve the skin-lightening effects of alpha-arbutin and resveratrol, finding that the patches enhanced intradermal delivery and slightly decreased the melanin index without affecting skin hydration or causing irritation over 24 hours.

This study reviewed evidence on injectable regenerative treatments for female pattern hair loss, finding that while PRP consistently improves hair density and thickness, the impact of such treatments on psychological wellbeing remains unclear, and patient-reported outcomes are inconsistently assessed.

The study found that severe insulin resistance and premature diabetes are common in patients with PCNT genetic defects, primarily affecting those over four years old, while not impacting early insulin signaling in adipocytes.

This study identified that blocking the PTGDR2 receptor in human hair follicles in vitro and in mice reversed the hair growth inhibition caused by PGD2, suggesting a potential approach for treating alopecia.

Certain substances can help skin cells become anti-inflammatory, aiding in tissue repair.

In this study, norgalanthamine was found to stimulate hair growth in cultured rat dermal papilla cells by activating the ERK 1/2, PI3K/AKT, and Wnt/β-catenin signaling pathways.

This case series reported that low-dose naltrexone may benefit patients with lichen planopilaris by reducing scalp symptoms and slowing disease progression, with no adverse effects observed in the patients.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

This study showed that treating mouse fibroblasts with TTNPB can efficiently convert them into dermal-papilla-cell-like cells with strong hair-inducing capacity, suggesting potential for hair follicle regeneration therapies.

This laboratory study found that activated platelet‐rich plasma supernatant enhanced hair growth signaling pathways in cultured human dermal papilla cells, suggesting potential for treating androgenic alopecia.

This case report describes the use of CO2 laser surgery to treat chronic pododermatitis and pseudopads in an 8-year-old obese dog, resulting in complete healing within four weeks after previous treatments provided only temporary relief.

This case report describes how a long-term combination of oral fatty acids and topical therapy appeared beneficial for managing autosomal recessive congenital ichthyosis in a goldendoodle with a PNPLA1 mutation.

This research reported that dermal progenitor cells can enhance split-thickness skin graft outcomes by improving dermal layer qualities and reducing itch and offer potential in skin wound healing using a flowable hydrogel for better cell delivery and survival.

This case report describes a 30-year-old Brazilian male who developed vitiligo lesions following diphencyprone therapy for alopecia areata.

This case report identifies an adolescent with symptoms indicative of Dunnigan-type partial lipodystrophy, emphasizing the need for early diagnosis to manage associated metabolic complications and improve self-esteem.

This study found that dissolving microneedle array patches containing mesoporous silica nanoparticles can deliver antigen-loaded nanoparticles into mice effectively, inducing strong immune responses similar to traditional subcutaneous injection.

This study demonstrates that machine learning-assisted fabrication of PRP-incorporated microneedles effectively promotes hair regrowth in AGA mice, outperforming minoxidil and mitigating biosafety risks associated with synthetic materials.

This article reviews the potential of PRP as a treatment for spinal pain but calls for established use guidelines and protocols before wider clinical adoption, with no new clinical results reported.
