In this study, Nd:YAG picosecond lasers using fractional micro-lens array were found to have a comparable effect to ablative fractional Er:YAG lasers in treating atrophic acne scars, with better safety profiles but slightly less patient satisfaction.

This study found that low-level laser therapy significantly improved hair count and reduced hair loss in patients with alopecia areata of the scalp.

This study generated a transcriptomic map of human hair follicles, identifying compartment-specific gene expression profiles that can aid in developing targeted therapies for hair follicle disorders.

This source highlights that fractional CO2 laser, as a minimally invasive technology, shows significant benefits in treating various skin and mucosal conditions by improving therapeutic outcomes, shortening recovery times, and enhancing precise personalized interventions through emerging technologies like AI and biomarker monitoring.

Laser treatment shows promise for hair growth, but needs further research.

This review explores clinical studies on low-level laser therapy (LLLT) for alopecia and suggests it may benefit patients unresponsive to conventional treatments, but larger studies are needed to confirm efficacy.

This study found that low level laser therapy at 655 nm significantly increased hair counts in males with androgenetic alopecia.

In this study, four male patients with extensively photodamaged scalps showed a 60-90% improvement in dyspigmentation, lentigines, and keratosis after a single treatment with the fractionated 1,927 nm thulium fiber laser, with no adverse events observed.

This review discusses the effects of low-level laser therapy in various biological processes for wound healing and tissue repair and reports no new results.

This study concluded that the Spa Touch system effectively retards hair regrowth, functioning like a "light razor" for quick and cost-effective epilation.

Hair shine can be measured by how it reflects laser light.

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.

This study concluded that low energy laser therapy may effectively complement classical treatment for scalp alopecia, leading to faster results, although long-term maintenance still requires ongoing classical therapy.

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 found that a 532 nm laser at 15 J/cm² enhanced the proliferation and differentiation of tendon-derived stem cells in rats, potentially accelerating tendon healing through the up-regulation of Nr4a1.

The excimer laser may help hair regrow in alopecia areata patients.

This study found that the multi-thresholding method was the most effective for segmenting hair during laser removal, as it clearly distinguished hair patterns with minimal noise.

This study discusses the importance of understanding the physical and biophysical factors involved in laser hair removal, highlighting the role of device parameters and skin type in treatment effectiveness, while also acknowledging potential adverse effects from laser light exposure.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

This review discusses low-level laser or light devices as an alternative treatment for androgenetic alopecia and highlights the need for further research to compare their efficacy with existing therapies.

This study suggests that a 1,550-nm fractional erbium-glass laser may stimulate hair growth in both an alopecia mouse model and human subjects with male pattern hair loss, though further research is needed to determine its clinical applications.

Lasers might help regrow hair in people with hair loss due to genetics.

This article discusses hairline design in hair restoration surgery and reports no new research data.

This editorial emphasizes the critical need for laser protection supervisors in the aesthetic sector due to a rise in laser-related claims attributed to inadequate training and safety protocol adherence, highlighting that better understanding and supervision can help mitigate risks.

Low level laser or LED therapy combined with infiltrations may help hair growth.

This study concluded that using an erbium:YAG laser for calvarium trepanation and granulation tissue induction is comparable to the rose head burr, offering a beneficial alternative method.

This study found that using dual-wavelength low-level laser therapy is more effective for hair regrowth in mice than single-wavelength treatment and significantly better than no treatment, based on 14 days of phototherapy with LED lights.

In this study, a 532 nm laser at 15 J/cm² increased the proliferation and tenogenic differentiation of tendon-derived stem cells in rats, mediated by Nr4a1 up-regulation.

This review discusses five popular resurfacing technologies for facial rejuvenation, highlighting their role in achieving smoother, healthier, and younger-looking skin, and reports no new clinical results.

This review discusses the modest efficacy of home-use laser and light devices for conditions like hair removal and acne, noting limited evidence and a lack of robust trials.
