This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

This review discusses the oral manifestations associated with hematologic conditions and nutritional deficiencies, without presenting new research results; it emphasizes the impact of blood disorders and vitamin deficiencies on oral health.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

Hair follicles in people with alopecia have lower levels of a key blood vessel growth protein.

This review discusses recent advancements in the management and diagnosis of primary cicatricial alopecias but reports no new clinical results; emerging insights suggest sebaceous gland dysfunction may play a role in their etiopathogenesis.

In this study, spiny mice showed superior cardiac recovery after myocardial infarction compared to other mouse strains, with enhanced myocardial preservation and functional stabilization.

This study found that Iranian patients with androgenetic alopecia had a higher terminal to vellus hair ratio compared to previous studies in Whites, suggesting potential onset of miniaturization.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.

This study reported that patterns of fibrosis identified through elastin staining may help distinguish specific forms of primary cicatricial alopecia in biopsy specimens, with certain patterns suggesting particular diagnoses.

This study suggests that for single biopsy specimens, transverse sections may be preferable for diagnosing noncicatricial alopecia, while vertical sections may be better for suspected lichen planopilaris.

This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

This study found that cold air can effectively preserve the epidermis when using an 810 nm diode laser, but it is slightly less effective than a chilled sapphire window in dark-haired pigmented pigs.

This article reviews recent advances and therapeutic approaches in treating alopecia areata, highlighting new potential treatments like pulse corticosteroid therapy, but reports no new research findings.

This study found that only one upper portion of a bisected human hair follicle successfully regenerated a complete new follicle with a pigmented hair in nude mice, although the overall success rate was very low.

In a study using a mouse model, HF-MSCs were reported to enhance ovarian function in cyclophosphamide-induced premature ovarian failure more effectively than HU-MSCs, potentially by preventing ferroptosis in granulosa cells via the KEAP1/NRF2/HO-1 pathway.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

The researchers developed a technique for processing and staining free hair samples using paraffin embedded blocks, revealing that routine staining does not color the enucleated cuticle, while the cortex and medulla show distinct colorations when stained.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

This study highlights lichen planopilaris as a form of scarring hair loss with symptoms like shedding and itching, and notes successful treatment options such as topical and oral antiinflammatory medications to preserve hair follicles by early intervention.

The document concludes that treatments for female hair loss and excess body hair are available, but managing expectations is important.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This article discusses the benefits of tumescent surgery, such as reduced blood loss and pain control, but reports no new clinical findings.

This review covers complications of neck lift surgery, their causes, ways to reduce them, and management strategies, without offering new clinical findings.

This article discusses facelift surgery, highlighting its refinement, outpatient use, low complication rates, and ease of mastery for advanced dermatologic surgeons, and reports no new clinical results.

This study observed that a wearable electric stimulation device significantly promoted hair regeneration in rats and mice, outperforming conventional pharmacological treatments and enhancing growth factor secretion.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This study found that serum ferritin levels were lower in premenopausal women with female pattern hair loss compared to healthy controls, suggesting a potential role for iron in hair loss.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

In this study, researchers developed a new murine model for transplanting vibrissae that mimics human hair transplantation, achieving successful hair growth in immune-deficient nude mice.
