This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

In this study, patients with keratosis pilaris exhibited significant quality of life impairment, with histopathology and dermoscopy revealing consistent skin and hair changes.

This study reports that quantitative trichoscopy, while noninvasive and convenient, provides less accurate hair density data compared to invasive histopathologic examination, which was demonstrated in a sample of adult Chinese individuals without alopecia.

This study found that human placenta extract may be a promising pulp-capping material, causing less intense chronic inflammation and thicker dentine bridge formation compared to mineral trioxide aggregate in dogs' teeth.

In this study, buccal mucosa grafts for urethroplasty in a rabbit model of congenital hypospadias showed good integration with minimal inflammatory response twelve weeks post-surgery.

This study found that using low-power lasers on cryosurgery-induced wounds in rats can prevent hair follicle necrosis and increase hair follicle numbers, with the experimental group showing significantly more hair follicles than the control group across all time points studied.

The researchers observed that in cases of alopecia areata with atypical features, histopathological confirmation may be necessary, as trichoscopic clues like loss of follicle ostia and vellus hairs were common, while typical features such as exclamation mark hairs were not always present.

This study found that platelet-rich plasma therapy significantly improved hair density, diameter, and reduced inflammation in androgenetic alopecia patients compared to placebo, though individual responses varied.

This study found that there was a significant discrepancy between histopathological examination and clinical diagnosis in alopecia cases, while vitamin D levels were not significantly associated with alopecia.

This study found that dissecting cellulitis of the scalp was more common in young men, with an association between longer disease duration and increased severity, but no link between age and severity.

This study found that melatonin, when administered to Wistar rats prior to and after radiation exposure, reduced oxidative stress markers and histopathological damage in skin tissue compared to radiation alone, suggesting it may effectively prevent and treat radiation-induced skin injury.

This study found that high-dose pterostilbene potentially reduced prostate hyperplasia and had strong antioxidant effects in male rats with benign prostatic hyperplasia, suggesting it might be more effective than vitamin C and resveratrol in similar contexts.

In this study, the researchers developed and optimized a curcumin nanocrystal gel to enhance skin permeability, reporting improved dissolution properties and antiproliferative effects on cell lines, suggesting it as a promising topical delivery system.

This study observed that keratosis pilaris is the most prevalent follicular keratotic disease, especially in adolescent and young adult females, and emphasized the key role of dermoscopy and histopathology in distinguishing it from other similar disorders and aiding in diagnosis.

In this study, the researchers developed minoxidil cubosomes using nanotechnology, which improved drug penetration in the skin, showed greater hair growth efficacy, and reduced adverse skin reactions compared to traditional minoxidil solutions.

This study suggests that RCM may be a promising non-invasive diagnostic tool for alopecia areata incognita, showing substantial agreement with histopathology while noting some discrepancies.

This study found that different types of seborrheic keratosis demonstrate diverse differentiation patterns, highlighting its undifferentiated and hyperproliferative state with varying keratinization directions.

A fungal infection can look like a different scalp condition in teens, leading to wrong treatment until proper tests are done.

This prospective observational study investigated 200 patients with non-scarring alopecia, concluding that accurate classification combined with individualized treatment, including combination therapies, significantly improved outcomes over monotherapy with topical minoxidil.

This study found that androgenetic alopecia patients showed significantly higher perifollicular lymphocytic inflammation and fibrosis compared to controls, emphasizing the need for histopathological evaluation during hair transplantation.

This study explored dermatoscopic and histopathologic findings of central centrifugal cicatricial alopecia beyond the vertex scalp, suggesting that dermatoscopy might serve as a less invasive diagnostic tool for subclinical disease.

This study suggests that hair follicles may be the primary target in the onset of various skin diseases, potentially spreading to affect the surrounding epidermis.

This study reports ten cases of non-marginal traction alopecia in women with very long hair, which was improved with shorter hair cuts and topical minoxidil application.

This study found that injection of adipose-derived adult stem cells improved hair density, thickness, and reduced inflammation in women with female pattern hair loss over 24 weeks.

This study explored the effects of a 50% hydroalcoholic UPBF extract on BPH in testosterone propionate-induced rats, finding significant improvements in prostate-related parameters and lower urinary tract symptoms at a 200 mg/kg dose, suggesting potential use in BPH management.

This study found that Teucrium polium L. subsp. geyrii Maire extract demonstrated a large safety margin in acute and subacute toxicity tests on mice and significantly enhanced wound healing in rats, especially with callus extract, by improving cell proliferation and wound contraction.

This paper reviews hair loss associated with various endocrine disorders and describes both traditional and emerging non-invasive diagnostic methods without presenting any new clinical results.

This study found that a new three-dimensional high-frequency ultrasound (3D-HFUS) can successfully visualize skin tumors and inflammatory hair diseases, offering promising noninvasive diagnostic and evaluation capabilities compared to traditional two-dimensional methods.

This case study reported a 15-year-old girl with a nevus sebaceus of Jadassohn, where a secondary neoplasm potentially developed into either pigmented trichoblastoma or pigmented basal cell carcinoma, highlighting the importance of early recognition and evaluation of such lesions for effective management.

AA-PRP injections significantly promote hair growth but need better study design for clear efficacy.
