The study suggests that CO₂ laser creates hair transplant channels with significantly less lateral thermal damage than Ho:YAG laser in the human scalp.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This study found that cystatin M/E strongly inhibits human cathepsin V and cathepsin L via distinct non-overlapping sites, suggesting an important role in human epidermal differentiation and hair follicle morphogenesis.

This review outlines the current state and future prospects of using layer-by-layer self-assembly for cell encapsulation in biomedical applications, such as cell-based biosensors, transplantation, and tissue engineering, while also discussing its limitations and potential advancements.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.

This review found that most studies support the effectiveness and safety of using hyaluronic acid fillers and laser treatments together for facial rejuvenation, but highlights that the evidence is limited to small, nonrandomized studies and additional research is necessary.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study found that Er–YAG laser treatment significantly enhanced skin absorption and follicular delivery of antialopecia drugs, suggesting a potential laser-assisted approach to treat alopecia.

This article reviews the use of the Nd:YAG laser for hair removal and reports no new research findings.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

This review discusses the use of laser and flashlamp technology for unwanted hair removal and reports no new clinical results, highlighting challenges with light-colored hair and treatment safety for darker skin tones.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This article reviews safe and effective hair removal options for dark-skinned patients and reports no new clinical results.

LLLT is a safe, promising hair loss treatment, but more research needed.

This review suggests that paradoxical hair growth after light-based treatments is unlikely due to the devices themselves; instead, it may be linked to other factors such as inflammation in individuals with certain conditions.

New method effectively analyzes finasteride and its stability.

In an animal study, researchers observed that a Chromolaena odorata layered-nitrile rubber transdermal patch significantly improved wound contraction, protein, hexosamine, and uronic acid levels, and collagen deposition in healing excision wounds in rats compared to a control group with an empty patch.

The authors concluded that low energy laser therapy may serve as a useful complementary treatment for skin diseases such as lichen planus, infectious finger pulpits, scalp alopecia, and crural ulcers.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.

This review discusses the evolution and potential of photobiomodulation therapy, highlighting its transition from skepticism to recognition in medical research; it reports no new experimental findings.

This study found that low-level laser treatment with the HairMax Lasercomb significantly increased terminal hair density in both men and women with pattern hair loss, with no serious adverse events reported.

This study observed that postlaser hair removal hypertrichosis occurred in 0.6% of patients and appeared more common in darker skin types, but was a rare phenomenon overall.

This study found that low-level laser therapy significantly increased hair growth in women with androgenic alopecia, achieving a 37% greater increase in hair counts compared to placebo.

This study found that low level laser therapy with a HairMax LaserComb improved hair counts and tensile strength in patients with androgenetic alopecia, particularly in males and vertex areas.

This review concluded that FDA-cleared low-level laser therapy devices are safe and effective for patients with male and female pattern hair loss who do not respond to or tolerate standard treatments.
