This review discusses guidelines for hair transplantation tailored to East Asian patients, focusing on hairline design, donor harvesting, and graft techniques, and reports no new clinical results.

This study found that scalp medical tattooing effectively improved cosmetic appearance and concealed bifid parietal whorls without complications in the patients evaluated.

This study concludes that anti-androgenic chemicals causing short anogenital distance in male fetuses also induce a feminized transcriptional profile in the perineum, implicating Wnt and estrogen signaling in the process.

This review discusses trichotillomania and traction alopecia, focusing on their clinical features, diagnostic criteria, and treatment options, but it reports no new research findings.

Terbinafine is more effective than itraconazole for toenail fungus, especially in older patients, and debridement improves its effectiveness.

This article discusses the diagnostic complexities of PCOS and emphasizes the importance of differentiating between polycystic ovaries and polycystic ovary syndrome; it presents no new experimental results.

This study found that targeting SV40 T antigen expression to hair follicles in transgenic mice caused abnormal hair structure and hair loss, but did not lead to cell immortalization or tumor formation in follicles.

In this study, researchers found that microRNAs and specific target genes, such as MiR-195 and genes like CHP1, SMAD2, FZD6, and SIAH1, play significant roles in regulating hair follicle initiation in cashmere goats.

This study found that the expression of LRIG1 in Merkel cell carcinoma tumors was associated with improved overall and cancer-specific survival.

This study found that topical fulvestrant did not significantly improve hair growth parameters in men and postmenopausal women with androgenetic alopecia, unlike minoxidil, which was more effective in men.

This chapter reviews classic regeneration models in planarian worms and amphibian limbs, focusing on the role of stem cells, and reports no new experimental results.

This study found that Cnidium officinale extract and its compound ferulic acid improved hair growth by promoting dermal papilla cell function and mitochondrial activity, suggesting their potential as a new treatment option for alopecia, possibly through estrogen receptor alpha activation.

Photographic imaging is crucial for documenting and managing hair loss, requiring careful preparation and standardization to be effective.

This review highlights the occurrence of yellow dots, a trichoscopic finding, in several scalp conditions beyond alopecia areata and reports no new clinical results.

This review discusses a quiz related to seborrheic dermatitis diagnosis and key findings from a previous study, but reports no new clinical results.

This review discusses the dermoscopic features of common hair and scalp disorders and reports no new clinical results, aiming to assist dermatologists in diagnosing conditions like tinea capitis and alopecia areata.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This study found that a peripilar white gray halo around hair emergence is a highly specific and sensitive dermatoscopic feature for diagnosing central centrifugal cicatricial alopecia in African American patients with mild central thinning.

This review describes various types of folliculitis based on their causes, clinical manifestations, and treatments, but reports no new clinical results.

This article reviews the use of trichoscopy for diagnosing common hair and scalp diseases and introduces a new classification for specific skin surface abnormalities, without presenting new clinical results.

This review highlights that in children, hair loss can be attributed to diverse conditions like alopecia areata and tinea capitis, and stresses the importance of a holistic approach to diagnosis and management, including psychosocial support due to limited effective treatments.

This study found that intralesional triamcinolone acetonide is effective for treating localized patchy alopecia areata, with dermoscopy aiding in early detection of clinical response and adverse effects.

This article reviews tinea capitis as a common infectious scalp condition in children, reporting no new findings.

This study found that Ecklonia cava enzymatic extract, particularly its component dieckol, promoted hair growth by increasing dermal papilla cell proliferation and inhibiting 5α-reductase activity in cultured vibrissa follicles and C57BL/6 mice.

This study reported that the most common hair loss disorder among children in south-east Nigeria was tinea capitis, and its clinical course was influenced by parental attitudes towards treatment.

Treat scalp and beard fungal infections early with oral antifungal medication and sometimes topical therapy, avoiding unnecessary allergy tests and surgery.

Most hair loss in children is caused by a few common conditions, and it's important to diagnose these properly and support the child's mental health.

This article reviews common causes of hair loss, noting that a well-directed history and examination are often sufficient for diagnosis, and reports no new clinical findings.

This study found that Ishige sinicola extract increased hair growth and cell proliferation in cultured vibrissa follicles and mice, suggesting potential benefits for treating alopecia through β-catenin activation and 5α-reductase inhibition.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.
