This article reviews the characteristics and distribution of alopecia areata and reports no new clinical results.

This study found that both fractional CO2 laser and cryotherapy were effective and safe treatments for alopecia areata, with the CO2 laser showing somewhat better results.

This literature review suggests that fractional lasers and microneedling, particularly when used with topical agents, may be effective treatments for alopecia areata; however, the small size and number of studies highlight a need for larger trials to confirm efficacy.

This study found that PRP was effective for treating alopecia areata with similar improvement across groups, while topical delivery via fractional CO2 laser or microneedling reduced injection pain.

This study presents two cases where intralesional methotrexate combined with ablative fractional CO2 laser treatment resulted in excellent outcomes for refractory alopecia areata.

This case report describes a promising response to platelet-rich plasma therapy, modified with triamcinolone acetonide, in treating alopecia totalis.

This study found that treating patchy alopecia areata with fractional CO2 laser and topical triamcinolone acetonide was more effective and safer than intralesional triamcinolone, despite higher initial discomfort, as it resulted in greater patient satisfaction and fewer adverse effects like skin atrophy.

In this clinical trial involving 60 patients, the Fractional CO2 laser was found to be more effective in achieving significant hair regrowth in alopecia areata compared to intralesional corticosteroid injections, with a 30% absolute improvement and reduced treatment failure rates.

This study observed that using fractional CO2 laser-assisted delivery of clobetasol propionate cream significantly improved treatment outcomes for localized alopecia areata compared to the cream alone, suggesting the laser's enhancing effect on hair regrowth.

In this study, combining ablative fractional microneedle radiofrequency with oral methylprednisolone was found to enhance hair density and mature hair rates in patients with alopecia areata better than oral methylprednisolone alone, though some adverse effects and increased hair shedding were noted over time.

This study found that fractional radiofrequency microneedling may be as effective and safe as intralesional corticosteroid injections for treating patchy alopecia areata, with potentially fewer side effects.

This study found that combining fractional CO2 laser with topical minoxidil 5% solution significantly improved hair growth in alopecia areata patients compared to minoxidil alone, with minimal side effects.

This study reviewed literature on traditional Chinese medicine external therapies for alopecia, finding them effective across various types, with combined internal and external approaches showing better results; however, concerns about the rigor and precision of current research highlight a need for further study.

This clinical trial found that transdermal delivery of 5-Fluorouracil using fractional CO2 laser resulted in a significantly better treatment response in alopecia areata patients compared to intralesional injections of the same drug, with a greater reduction in the Severity of Alopecia Tool Score.

This report describes ARTAS, a robotic hair transplant technology with advanced mechanical and recognition capabilities, which has gained popularity in China since 2016 due to its ease of use and efficient hair follicle harvesting.

This study found that both fractional and excimer lasers are effective in increasing hair density and promoting regrowth in various types of alopecia, although further trials are needed to compare their efficacy to more traditional treatments.

In this retrospective study, a combined therapy of ablative fractional Er: YAG laser and medication was more effective in treating male androgenetic alopecia than medication alone, without causing serious adverse effects, as evaluated over 24 weeks.

This clinical trial found that combining fractional CO2 laser with bimatoprost solution significantly improved alopecia areata treatment outcomes compared to bimatoprost alone, as measured by a more substantial reduction in SALT scores and higher patient satisfaction over 12 weeks.

This review article evaluates new treatment techniques for androgenetic alopecia, including low-level laser therapy, platelet-rich plasma therapy, microneedling, and topical growth factors and peptides, reporting positive outcomes such as hair regrowth and improved hair density and thickness.

This article discusses Traditional Chinese Medicine approaches to treating alopecia areata, outlining etiology, treatment stages, and methods, but does not report new clinical results.

This study found that combining fractional CO2 laser treatment with platelet-rich plasma led to a statistically significant improvement in hair regrowth for male androgenetic alopecia, compared to using the laser treatment alone.

This study found fractional carbon dioxide laser therapy effective in treating alopecia areata, both alone and with topical treatments, suggesting decorin's involvement in improving hair growth.

This review suggests that fractional CO2 laser treatment may be a promising option for treating alopecia areata with a good safety profile.

In this study, both topical clobetasol propionate and fractional Er: YAG laser followed by topical steroids demonstrated significant improvement in patients with alopecia areata, but the combined laser and steroid treatment was found to be more effective and safe.

This case report describes a 62-year-old male with multiple warty dyskeratomas found on the scalp, chest, abdomen, and lower back, a rare presentation confirmed by histological findings consistent with warty dyskeratoma, as noted by the researchers.

This study found that micro-needling with triamcinolone acetonide led to the best treatment outcomes for alopecia areata compared to other methods of trans-epidermal drug delivery.

This study found no significant difference in the overall effectiveness of fractional CO2 laser plus triamcinolone acetonide versus microneedling plus the same treatment for resistant alopecia areata, though initial hair regrowth appeared more frequently in the laser group.

This article discusses trichotillomania and trichoteiromania, focusing on their clinical presentation, main trichoscopic features, and similarities in hair loss patterns but reports no new research findings.

In this study, androgenetic alopecia in Nigerians was associated with dyslipidemia, alcohol intake, and sedentary lifestyle, with severity linked to age, systolic blood pressure, and obesity.

This study observed that combining nonablative fractional laser treatment with topical minoxidil led to hair regrowth in Chinese alopecia areata patients, noting complete regrowth in some patients and no relapse in the majority at a one-year follow-up, without reported side effects.
