This randomized trial found that diode laser achieved more favorable long-term hair removal outcomes but induced more discomfort and transient adverse effects compared to intense pulsed light in women with Fitzpatrick skin types I-IV.

This study developed a hair-on-a-chip model that supports the maturation of hair-follicle-like tissue under long-term culture conditions, suggesting its promise for studying hair regeneration and testing scalp-targeted therapies.

This study determined that low-level light therapy and fractional lasers are effective and safe treatments for androgenetic alopecia, especially when combined with other agents like minoxidil, PRP, or growth factors.

This study found that low-level light therapy and fractional lasers are effective and safe treatments for androgenetic alopecia, with the greatest improvements in hair density and thickness seen in combination therapies.

This study reports that low-level light therapy and fractional lasers are effective and safe treatments for androgenetic alopecia, with more pronounced results when combined with other therapies.

This review concluded that laser-based therapies, particularly low-level lasers and fractional ablative lasers, are effective for treating hair loss, with combination therapies showing superior efficacy compared to monotherapies.

This meta-analysis found that laser-based therapies showed promising clinical benefits in treating scarring alopecias, such as disease stabilization and symptom improvement, but highlighted the need for high-quality randomized controlled trials due to serious risk of bias and methodological limitations in existing studies.

Among individuals with skin types II and III, this study found the 755 nm laser more effective for axillary hair removal than the dual-wavelength laser, with a better safety profile and enduring results up to 12 months.

In this study conducted among adult dermatology clinic attendees in Saudi Arabia, laser hair removal-related anxiety was generally low, but misconceptions were common; increased knowledge was linked to reduced anxiety, suggesting educational interventions could improve informed decision-making.

This study found that combining Alexandrite laser with iontophoresis of chymotrypsin and papain enzymes reduced the laser pulse requirements compared to laser alone for treating paradoxical hypertrichosis in women with facial hirsutism, suggesting potential clinical benefits in managing this condition.

This study found that combining laser ablation with nanoparticulate drug formulations effectively enhanced the skin and follicular delivery of hydrophilic drugs like minoxidil and minocycline in preclinical models.

This study reviewed the literature on laser and light technologies in dermatology, highlighting their varied clinical applications such as skin rejuvenation, acne scar treatment, and hair removal, alongside their potential for combining with AI to improve outcomes.

In this study, the combination of low-level laser therapy and topical minoxidil was found to improve hair density and diameter more effectively than minoxidil alone in treating androgenic alopecia, with similar safety profiles observed in both groups.

This review reports that stem cell-based therapies, natural oils, and low-level laser therapy may offer promising and safe alternative treatments for alopecia, although further standardized trials are needed for confirmation.

Laser treatment boosts hair growth by activating a key growth factor.

This study reported that a non-ablative fractional laser effectively improved visible hair growth and scalp appearance in both men and women with androgenetic alopecia, with a high success rate in identifying post-treatment improvements, and no adverse events were documented among the 132 patients evaluated.

In this study, both erbium: YAG and erbium: glass lasers were found to be effective in treating androgenetic alopecia by improving hair density, growth rate, and thickness, particularly when combined with other therapies like minoxidil or platelet-rich plasma, though individual patient responses varied.

In this study, 13 androgenetic alopecia patients receiving Er: Yag laser treatment showed a significant increase in Staphylococcus spp. three days post-treatment, suggesting the laser may help modulate scalp microbiota balance.

This study suggests that hair removal lasers, potentially combined with topical minoxidil, may target and treat the underlying mechanisms of trichoepithelioma lesions effectively, though clinical trials are needed to verify this approach.

This review examines ultrasound-assisted and laser-based transdermal drug delivery technologies, highlighting their success in enhancing drug penetration through the skin but also noting challenges such as parameter optimization, potential skin irritation, and high equipment costs.

This review discusses low-level laser therapy and fractional laser therapies as alternative treatments for androgenetic alopecia, but reports limited evidence of their efficacy due to small sample sizes and potential study biases.

This review indicates that various laser therapies, alone or combined with other treatments, show potential in improving hair density and treating androgenetic alopecia, but outcomes can vary, underscoring the importance of personalized treatment.

In this reported case, a 13-year-old boy with alopecia areata experienced complete lesion resolution and varied hair regrowth across different laser treatment parameters after three months of combined oral prednisone, topical ointment, and CO2 fractional laser therapy.

In this study, researchers found that combining fractional CO2 laser sessions with topical dutasteride was more effective in improving male androgenic alopecia than using the laser treatment alone, as observed through global photo assessments and dermoscopic parameters.

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 review highlights the various cosmetic and therapeutic applications of laser technologies in dermatology, discussing the mechanisms, safety, efficacy, and recent advancements to provide a comprehensive overview of their uses and potential future implications.

This study found that wound bed perfusion strongly predicts skin graft viability by correlating with lower necrosis extension on both the scalp and lower limb, unlike perfusion of the wound margin and donor skin, which showed no significant correlation.

This systematic review found that light and laser therapies, including excimer and erbium-glass lasers, generally increase hair density and diameter in various types of alopecia, with particularly notable effects in androgenic alopecia but limited efficacy in telogen effluvium.

This case report describes a healthy Thai male who developed severe folliculitis following diode laser hair removal, which improved significantly with prednisolone and benzoyl peroxide treatment.

This study found that bi-weekly 1550nm low-level laser therapy significantly improved hair loss conditions and scalp health in participants, suggesting its potential as an effective non-invasive treatment option.
