This study found that Notch signaling is crucial for maintaining proper melanocyte distribution and preventing premature differentiation in the melanocyte lineage within hair follicles.

This study found that pigmented vellus and upright regrowing hairs are the only predictive trichoscopic markers of hair regrowth in patients with alopecia totalis and universalis.

This case study reported significant but temporary hair regrowth and skin repigmentation in a patient with vitiligo and alopecia areata during treatment with oral ruxolitinib.

This case report describes a rare instance of melanocytic matricoma, a benign pigmented papule found in sun-damaged skin of an elderly individual, highlighting its distinct clinical and pathological features.

This case report describes a successful eyebrow reconstruction using hair follicle micrografts in a patient with dormant keratosis pilaris atrophicans, demonstrating potential for this technique in similar conditions.

This review discusses the potential use of platelet-rich plasma for treating melasma, suggesting its effectiveness but noting the need for more extensive studies to confirm these findings.

This study suggests that thermal imaging may aid in diagnosing cellulitis, potentially improving patient care, although its applicability to certain cases requires further investigation.

In this case report, follicular unit extraction successfully treated stable segmental vitiligo in the inguinoscrotal region.

This study concluded that autologous platelet-rich plasma is a safe and effective technique for improving aesthetic concerns such as contour defects, pigmentation issues, and indurated lesions.

This study suggests that combining tranexamic acid with low-dose oral retinoids may offer moderate to good improvements for lichen plan pigmentosus, although larger trials are needed for confirmation.

In this study, researchers identified exosomal miR-199a-3p as a key factor in the regulation of melanogenesis by dermal papilla cells, finding that it enhances melanocyte proliferation and melanin production, suggesting potential therapeutic targets for pigmentation disorders.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.

This report describes two cases where pemphigus lesions developed at sites of cosmetic procedures, suggesting these treatments might trigger the disease and should be distinguished from other post-surgery complications.

This study found that platelet-rich plasma is effective and safe for treating chronic wounds, particularly diabetic and venous ulcers, and vitiligo, without increasing the risk of infection.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This case report challenges the traditional view by documenting reversible vision loss following scalp injections of platelet-rich plasma, attributed to an inflammatory or microvascular event, treatable with corticosteroids.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This study reported that fire needle therapy improved skin lesions, increased melanocyte numbers, and boosted melanin levels in a vitiligo mouse model by upregulating the Wnt/β-catenin signalling pathway, suggesting its potential role in treating vitiligo through promoting pigmentation.

This study suggests that systemic exposure to black eyeliner pigment may occur, potentially leading to permanent eyelash loss following the procedure.

This case report describes a child with hypopigmented mycosis fungoides successfully treated with UVA1 light therapy.

This article discusses various surgical options for treating leukotrichia in vitiligo patients and reports that hair transplantation shows more promising results, particularly for eyebrows and eyelashes, compared to previous methods.

This study found that using a nonablative 1927 nm wavelength laser followed by hydroquinone cream is safe and effective for treating postinflammatory hyperpigmentation in patients with dark skin types.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study found that Rac1 activity in specific skin compartments is sufficient for hair formation, but results in hair with altered structure and pigmentation compared to normal.

Results are not reported in this abstract; it discusses recent advancements in understanding vitiligo's pathogenesis, treatment, and comorbidities, emphasizing emerging areas like gut microbiome involvement and highlighting the disease's reclassification as a systemic condition with evolving therapies.

This study found that MRL/MpJ mouse dorsal skin wounds heal with similar scar formation and collagen deposition as C57bl/6 and Balb/c mice.

A new surgical technique using vellus hair grafts effectively treated vitiligo without causing unwanted hair growth.
