In this study, adding platelet-rich plasma to minoxidil and finasteride treatment for patterned hair loss improved hair outcomes with minimal side effects compared to using minoxidil and finasteride alone.

This study found that recombinant human HGF/SF injections altered hair follicle growth cycles and mildly promoted hair elongation in mice, depending on their hair cycle stage.

This article reviews emerging treatments for androgenetic alopecia, including topical 5-alpha-reductase inhibitors and prostaglandin modulators, but reports no clinical results and calls for further efficacy evidence, especially for PRP.

ACTH promotes hair growth in mink, but α-MSH does not.

In this study, carotene injected into the skin was converted into vitamin A by sebaceous gland cells, where it was not normally detectable.

This case report describes a woman who experienced frontal edema after topical minoxidil application following mesotherapy, noting that excessive absorption of minoxidil may cause localized vasodilatory side effects.

This study found that PBMCsec has anti-fibrotic effects on mouse and human skin scars by regulating pro-fibrotic gene expression and inhibiting myofibroblast differentiation and elastic fiber breakdown.

This single-patient case study reported promising results for severe, corticosteroid-resistant alopecia areata, with treatment using exosomes derived from mesenchymal stromal cells leading to almost complete hair regrowth in 12 weeks and favorable changes in inflammatory markers, suggesting potential for further investigation.

This case report highlights significant hair regrowth in a Malaysian woman with localized alopecia areata after intralesional triamcinolone acetonide treatment at a concentration of 5 mg/mL.

In this case study, a 14-year-old boy with treatment-resistant diffuse alopecia areata achieved complete hair regrowth following three monthly sessions of microneedling combined with injections of triamcinolone, dutasteride, and synthetic exosomes, suggesting that exosome-based therapy could be a promising alternative for managing refractory autoimmune alopecia.

This study reports that a novel multimodal approach, combining tattoo machine–assisted drug delivery of hair loss treatments with oral and topical medications, may enhance hair density and thickness in androgenetic alopecia patients, though larger controlled studies are needed to confirm these early findings.

PRP treatment improved skin pigmentation and appearance in facial lichen planus pigmentosus.

This study summarizes the therapeutic use of mesotherapy using vitamins, trace elements, and stem cell extracts for treating alopecia, noting its effectiveness in addressing both androgenetic alopecia and telogen effluvium as demonstrated in various clinical trials.

A 72-year-old man was diagnosed with a rare skin form of Rosai-Dorfman disease after years of misdiagnosis.

In this study, injecting Nε-(carboxymethyl) lysine into skin tissue weakened hair shaft and follicle formation, likely by inhibiting cell proliferation and migration needed for hair follicle morphogenesis.

This experimental study found no significant difference in hair follicle characteristics after short-term treatment with autologous platelet-rich plasma in individuals with androgenic alopecia compared to placebo.

This study found that administering an adenovirus vector to increase Sonic hedgehog gene expression in mouse skin accelerated the transition of hair follicles into the growth phase, promoting hair growth.

This review discusses the potential of microneedles to enhance transdermal drug delivery by expanding the range of deliverable drugs, highlighting fabrication methods, material choices, and applications, but notes existing challenges with sustained delivery, cost-effectiveness, and large-scale production.

This study found HLA and beta 2-microglobulin antigens in various skin structures, with specific localization patterns in keratinocytes and hair follicle components, but not in eccrine or apocrine glands.

This review discusses allergic reactions to pollen in dogs, cats, and horses and suggests that these animals' spontaneous allergies could serve as models for translational clinical studies applicable to human allergies.

This study found that lymphatic vessels promote hair follicle growth in mice and may represent new therapeutic targets for hair loss conditions.

This study found that low-dose topical alpha-terthienyl combined with UVA radiation can induce cutaneous photosensitization in guinea pigs, suggesting a possible photochemotherapy approach for skin diseases like psoriasis.

In this study, FCO2 laser treatment showed significantly better improvement for alopecia areata compared to traditional intralesional corticosteroid injections, with no serious side effects or relapse observed.

This study found that treating androgenetic alopecia with platelet rich plasma increased hair density and diameter while decreasing the proportion of telogen and vellus hairs.

This study demonstrated that adipose derived stem cells nanovesicles enhanced hair growth and reduced sebum secretion in androgenetic alopecia, showing effects comparable to minoxidil in laboratory and mouse models.

This review discusses the effectiveness of adipose-derived stem cells in treating alopecia, reporting on various clinical studies but presenting no new clinical results.

This study found that follicular unit extraction can be safely performed without bupivacaine and nerve blocks, using lignocaine with adrenaline as an effective anesthetic for patients with certain grades of androgenetic alopecia.

New inhibitors may help treat hair loss by promoting fat cell growth in the skin.

PrEP doesn't increase STI risk in high-risk men, anti-androgen drugs may lower ICU admission for male COVID-19 patients, a 3-point injection is better for crow's feet, and the 'Geriatric-8' tool could help assess frailty in older skin cancer patients.

This article discusses the diagnosis and management of allergic dermatoses in dogs, focusing on clinical diagnosis, complementary tests, and various treatment strategies, but it reports no new results.
