This review discusses the use of helmet designs in integrative medicine and transcranial photobiomodulation, highlighting new developments and potential future advancements in sensor-controlled therapy helmets, but reports no new clinical results.

This study observed that PRP treatment resulted in greater improvement in hair thickness and density in alopecia areata patients compared to LLLT, with benefits sustained over 12 weeks.

This expert group provided recommendations for preparing and using platelet-rich plasma in treating androgenetic alopecia, suggesting a manual double-spin method and specific dosing, although further studies on injectable platelet-rich fibrin are needed.

Laser and light therapies can help regrow hair but need more research for best results.

This review covers the pathogenesis, diagnosis, and potential new treatments for androgenetic alopecia but reports no new clinical findings, highlighting an ongoing need for effective therapies.

This clinical review evaluates current evidence on various adjunctive therapies for androgenetic alopecia, highlighting modest benefits for some interventions but emphasizing significant gaps and the need for rigorous, high-quality research to guide effective management strategies.

This case report observed marked hair regrowth in a patient with refractory alopecia areata using a combination of platelet-rich plasma, low-level light therapy, and microneedling alongside topical and oral agents.

This study examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

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 study, the combination of low level light therapy with arginine, arterial extract, or biotin tripeptide-1 was associated with improvements in hair density and follicle structure in androgenic alopecia.

In this review, the authors summarized non-pharmacological therapies that may promote hair growth and regeneration as alternatives to traditional drug treatments and hair transplantation, both of which have notable limitations.

In this randomized controlled trial involving breast cancer patients undergoing chemotherapy, this study investigated the efficacy of low-level light therapy for preventing hair loss, measuring outcomes like hair count and patient quality of life, but the abstract does not report specific results.

This review examines the mechanisms of hair follicle development and regeneration, discussing current hair loss treatments and emerging therapies like low-level laser therapy and stem cell therapy, which the authors suggest show promise in managing hair loss.

This study describes androgenetic alopecia as a common non-scarring hair loss condition primarily influenced by genetic factors and androgen sensitivity, notably impacting psychosocial well-being, especially in females and younger males seeking treatment.

This review proposes a combination treatment scheme with a rotational approach for managing androgenetic alopecia, drawing on evidence for effectiveness, long-term use convenience, and patient acceptance, but presents no new clinical results.

This study evaluated a novel hand-held low-level light therapy device for treating mild-to-moderate acne, finding it significantly reduced inflammatory lesions and moderate acne severity without severe adverse reactions, while also reducing Cutibacterium acnes viability in vitro.

This study's review of existing research found insufficient data to determine the impact of skin type on the effectiveness of low-light laser therapy for hair growth in androgenetic alopecia, with a notable lack of data on darker skin types.

This review of low-level laser therapy for patterned hair loss found that red-spectrum light may be effective for hair growth, but larger case-controlled studies are needed to further support this conclusion.
