In this study, microneedling with a depth of 0.6 mm, alongside minoxidil, significantly improved hair count and thickness in patients with androgenetic alopecia compared to minoxidil alone, and was more beneficial than a 1.2 mm depth.

This study found that microneedling with longer needles (3 mm) showed better hair regrowth in dogs with hair cycle arrest, although most experienced recurrent hair loss during follow-up. Some dogs also developed minor, temporary itching.

A 2 mm needle is effective and precise for skin injections.

This study reported that while no synthesized compounds surpassed finasteride in 5α-reductase inhibitory activity, certain 4-azasteroid-2-oximes exhibited notable inhibition.

In this study, researchers observed that acute stress increased levels of the enzyme 5αR2 in the medial prefrontal cortex of male rats, affecting stress reactivity, but this effect was not seen in females.

This study reported that metallic-glass-coated tattoo needles reduced trauma and improved tattoo quality in pig skin experiments compared to uncoated needles.

This study found that transtherapy, a treatment using Korean medicine, significantly improved acne scars, reducing the scarring grade from an average of 3.5 to 1.5 in moderate and severe cases.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

This article reports that the use of an ultrasharp tungsten electrode was deemed a useful tool in hundreds of scalp reduction procedures for hair restoration at Peterson Medical Institute.

In this study, herbal extracts commonly used in traditional medicine were observed to significantly increase the proliferation of human dermal papilla cells, suggesting potential as alternative therapies for enhancing hair growth.

In this study, the combination of petroleum ether extracts from Jacquinia ruscifolia flowers and Thuja orientalis strobili demonstrated synergistic larvicidal effects against third-instar Culex quinquefasciatus larvae, achieving 100% mortality at 250 ppm with noted synergism particularly in a 1:2 ratio.

This study found that Ecklonia cava polyphenols increased human dermal papilla cell proliferation and extended hair shaft length in vitro and ex vivo, suggesting potential as a therapeutic candidate for hair loss.

This study found that millimolar concentrations of minoxidil in the skin induced VEGF production through HIF-1 stabilization by inhibiting PHD-2, implying a molecular mechanism for hair growth promotion.

This study found that minoxidil-loaded niosomes with a Span 60 and cholesterol ratio of 1:2 significantly increased skin retention of minoxidil compared to control gel.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

This study reports the development of a prototype robotic hair transplant system capable of efficiently harvesting and implanting hair grafts, showing promising accuracy and performance in tests using a spherical scalp phantom.

This study found that goat placenta extract, when combined with PEGylated liposomes and microspicule gel, significantly promoted hair regrowth in patients experiencing hair loss due to chemotherapy by enhancing hair cell proliferation without causing skin irritation over a 12-week application period.

This study reports that a novel eyelash transplantation method using chalazion forceps effectively thickens and enhances eyelashes by precisely placing transplanted hairs in a narrow recipient area, with approximately 85-92% of transplanted lashes expected to grow within 12 months.

Combining topical dutasteride with microneedling is more effective for hair growth than microneedling alone.

A cosmetic procedure can lower the hairline by up to 10 cm, with high satisfaction but potential for temporary sensation loss and rare risks.

In this study, micro-autologous fat transplantation (MAFT) for frontal augmentation using the MAFT-GUN showed high patient satisfaction and no complications among 178 patients, suggesting it may be a reliable method for forehead contouring.

FUE hair transplantation using a micromotor is effective and gives natural results with few complications.

This study demonstrated that a finasteride-loaded proniosome significantly enhanced transfollicular delivery and hair growth in mice without causing skin irritation, with effects comparable to a 2% minoxidil solution.

This study investigated the use of dissolving microneedle patches to improve the skin-lightening effects of alpha-arbutin and resveratrol, finding that the patches enhanced intradermal delivery and slightly decreased the melanin index without affecting skin hydration or causing irritation over 24 hours.

This review evaluates six primary studies on androgenetic alopecia treatments and suggests topical minoxidil or finasteride as first-line options, recommending further research into treatments and practice guidelines.

This case report observed complete repigmentation of a stable vitiligo patch with body hair transplantation in a 28-year-old man, with no recurrence after 3 months.

This study found that bimatoprost stimulated hair growth in both human scalp follicle cultures and mouse pelage in vivo, suggesting it might offer a promising treatment for scalp alopecias.

In this study, the novel powered FUE method was associated with faster harvesting time and lower graft transection rates compared to manual FUE in male patients with alopecia.

This article argues for a standardized nomenclature system in hair restoration surgery to reduce confusion and validate the field as a scientific discipline, but reports no new clinical results.

This study found that the novel powered FUE (P-FUE) technique reduced harvesting time and graft transection rates in hair restoration compared to manual FUE, with broader patient applicability.
