Abstract
The rapid advancement of sequencing technologies has enabled the generation of vast datasets, allowing for the in-depth analysis of sequencing data. This analysis has facilitated the validation of novel pathogenesis hypotheses for understanding and treating diseases through ex vivo and in vivo experiments. Androgenetic alopecia (AGA), a common hair loss disorder, has been a key focus of investigators attempting to uncover its underlying mechanisms. Abnormal changes in mRNA, proteins, and metabolites have been identified in individuals with AGA, and future developments in sequencing technologies may reveal new biomarkers for AGA. By integrating multiple omics analysis datasets such as genomics, transcriptomics, proteomics, and metabolomics-along with clinical phenotype data-we can achieve a comprehensive understanding of the molecular underpinnings of AGA. This review summarizes the data-mining studies conducted on various omics analysis datasets as related to AGA that have been adopted to interpret the biological data obtained from different omics layers. We herein discuss the challenges of integrative omics analyses, and suggest that collaborative multi-omics studies can enhance the understanding of the complete pathomechanism(s) of AGA by focusing on the interaction networks comprising DNA, RNA, proteins, and metabolites.

Abstract
Low-level light therapy (LLLT), also known as photo biomodulation (PBM), is a type of optical therapy that uses red or near-infrared lasers or light-emitting diodes (LEDs) for medical treatment. The laser wavelengths involved in PBM typically range between 600-700 nm and 780-1100 nm, with power densities ranging between 5 mW/cm2 and 5 W/cm2. PBM is a series of biochemical cascades exhibited by biological tissues after absorbing a certain amount of energy from light. PBM has been widely used in clinical practice in the past 20 years, and numerous clinical trials have demonstrated its biological efficacy. However, the underlying mechanisms have not yet been fully explored. In this paper, we have summarized the research into PBM over the past two decades, to identify the important mechanisms of the biological effects of PBM from the perspective of molecular mechanisms, cellular levels, and tissue changes. We hope our study provide a theoretical basis for future investigations into the underlying mechanisms.

Abstract
Photobiomodulation (PBM) is an emerging treatment modality in dermatology with increasing office and home-based use. PBM is the use of various light sources in the red light (620-700 nm) and near-infrared (700-1440 nm) spectrum as a form of light therapy. PBM is often administered through low-level lasers or light-emitting diodes. Studies show that PBM can be used effectively to treat conditions secondary to cancer therapies, alopecia, ulcers, herpes simplex virus, acne, skin rejuvenation, wounds, and scars. PBM offers patients many benefits compared to other treatments. It is noninvasive, cost-effective, convenient for patients, and offers a favorable safety profile. PBM can be used as an alternative or adjuvant to other treatment modalities including pharmacotherapy. It is important for dermatologists to gain a better clinical understanding of PBM for in-office administration and to counsel patients on proper application for home-use devices to best manage safety and expectations as this technology develops. PBM wavelengths can induce varied biological effects in diverse skin types, races, and ethnicities; therefore, it is also important for dermatologists to properly counsel their skin of color patients who undergo PBM treatments. Future clinical trials are necessary to produce standardized recommendations across conditions and skin types.

Abstract
Introduction Alopecia areata (AA) is an autoimmune disease characterized by T cell-mediated attack on the hair follicle. Although there are a wide range of therapies, the majority of them are not satisfactory due to side effects, pain due to intralesional injections or limited efficacy. In this study, we sought to evaluate the efficacy, influence factors, and safety of 308 nm excimer lamp used in a monthly basis in a double-stacked pulse manner for the treatment of AA. Methods This was a prospective study, using 308 nm excimer lamp in a double-stacked pulse therapy for AA. The primary endpoint was the improvement in SALT score. Results A total of 40 patients with AA were enrolled in this study. Forty (100%) patients achieved clinical response. Hyperpigmentation and erythema occurred on the treated alopecic areas of all patients but they were considered tolerable. Patients of younger age or with a smaller area of affection had a better overall treatment response. Conclusion 308 nm excimer lamp therapy is an excellent option for single or multiple AA because it achieves a good clinical response with less adverse effects than other therapies. This therapy may be useful for low-income countries where new JAK inhibitors are not available, however, for patients with extensive hair loss, it is not as effective and thus, it may be unfit for patients with alopecia totalis and alopecia universals.

Abstract
Androgenic alopecia is a hereditary condition of pattern hair loss in genetically susceptible individuals. The condition has a significant impact on an individual's quality of life, with decreased self-esteem, body image issues and depression being the main effects. Various conventional treatment options, such as minoxidil, finasteride and herbal supplements, aim to slow down hair loss and promote hair growth. However, due to the chronic nature of the condition the financial cost of treatment for androgenic alopecia is very high and conventional treatment options are not universally effective and come with a host of side effects. Therefore, to address the limitations of current treatment options a novel regenerative treatment option is required. One promising approach is organoids, organoids are 3D cell aggregates with similar structures and functions to a target organ. Hair follicle organoids can be developed in vitro. However, the main challenges are to maintain the cell populations within the organoid in a proliferative and inductive state, as well as to promote the maturation of organoids. Photobiomodulation is a form of light therapy that stimulates endogenous chromophores. PBM has been shown to improve cell viability, proliferation, migration, differentiation and gene expression in dermal papilla cells and hair follicle stem cells. Therefore, photobiomodulation is a potential adjunct to hair follicle organoid culture to improve the proliferation and inductive capacity of cells.

Abstract
The use of low-light laser therapy to treat androgenetic alopecia is a promising modality to restore hair growth. However, the effect of skin color on response to laser therapy for hair growth has not been systematically explored in the literature. The objective of this study is to systematically assess through a comprehensive literature search of the MEDLINE database whether skin type data were collected in clinical trials and analyzed in each study and determine if we can estimate an effect. 10/22 studies have defined inclusion criteria as Fitzpatrick skin types I-IV. No studies mentioned effects on darker skin types, Fitzpatrick skin types V-VI. Only 5/10 studies had statistical data on efficacy depending on Fitzpatrick skin type, with four showing no effect and one showing a significant positive effect with darker skin types having faster rate of hair growth. There are not enough data to conclude whether skin type effects laser-induced hair growth in androgenic alopecia. The studies are severely lacking in sample size. One showed a potential effect. Importantly, there are no data on black or brown skin colors. Development of optimal laser irradiating wparameters through the prediction of personalized absorbance based on skin color measurement is needed.

Abstract
Background Androgenetic alopecia (AGA) leads to thinning of scalp hair and affects 60%~70% of the adult population worldwide. Developing more effective treatments and studying its mechanism are of great significance. Previous clinical studies have revealed that hair growth is stimulated by 650-nm red light. Objective This study aimed to explore the effect and mechanism of 650-nm red light on the treatment of AGA by using ex vivo hair follicle culture. Methods Human hair follicles were obtained from hair transplant patients with AGA. Hair follicles were cultured in Williams E medium and treated with or without 650-nm red light. Real-time RT-PCR and immunofluorescence staining were used to detect the expression level of genes and proteins in hair follicles, respectively. RNA-sequencing analysis was carried out to reveal the distinct gene signatures upon 650 nm treatment. Results Low-level 650 nm red light promoted the proliferation of human hair follicles in the experimental cultured-tissue model. Consistently, 650 nm red light significantly delayed the transition of hair cycle from anagen to catagen in vitro. RNA-seq analysis and gene clustering for the differentially expressed genes suggests that leukocyte transendothelial migration, metabolism, adherens junction and other biological process maybe involved in stimulation of hair follicles by 650-nm red light treatment. Conclusion The effect of 650-nm red light on ex vivo hair follicles and the transcriptome set which implicates the role of red light in promoting hair growth and reversing of miniaturization process of AGA were identified.

Abstract
Photobiomodulation, otherwise known as low-level laser (or light) therapy, is an emerging modality for the management of hair loss. Several randomized trials have demonstrated that it is safe and potentially effective on its own or in combination with standard therapies. These devices come in many forms including wearable caps or helmets that afford hands-free and discreet use. Models with light-emitting diodes (LEDs) are less expensive compared to laser-based devices and do not require laser safety considerations, thus facilitating ease of home use. Limitations include cost of the unit, risk of information bias, and lack of standardized protocols. Finally, as with any hair loss treatment, patients' expectations with regards to therapeutic outcomes must be managed.

Abstract
Androgenetic alopecia (AGA) is a global challenge, affecting a large number of people worldwide. Efficacy of the existed treatments can barely meet the demands of patients. Patients who are poorly responding to those treatments are seeking for a more effective and suitable technique to treat their disease. Low-level light therapy (LLLT) is a newly developed technique, which has been proved to stimulate hair growth. Based on the function principle of LLLT in other domains and refer to the published literatures, we write this review to neaten and elucidate the possible mechanism of LLLT in the treatment of AGA. A review of published literature which is associated with keywords LLLT, photobiomodulation, AGA, treatment, hair growth, and mechanism was performed to elucidate the proposed mechanism of LLLT in the treatment of AGA. The present study shows that LLLT can accelerate hair growth in AGA patients. The proposed mechanism of LLLT in treating AGA may vary among different specialists. But we can summarize the consensual mechanisms as follows; low-level light absorbed by chromophores can lead to the production of nitric oxide (NO) and the modulation of reactive oxygen species (ROS). These mobilized molecules subsequently activate redox-related signaling pathways in hair follicle cells and perifollicular cells. Finally, these activated cells participate in the regrowth of hair follicle. Even though the efficacy of LLLT in the treatment of AGA in both men and women has already been confirmed, the present studies focusing on discovering LLLT are still inadequate and unsystematic. More studies are needed to standardize the optimum treatment parameters applied in promoting hair growth and determine the long-term safety and efficacy of LLLT. Current recognitions about the mechanisms of LLLT, mainly focused on the molecules that may take effect, neglected different cellular components that are functional in the hair follicle macro-environment.

Abstract
Introduction: The widespread application of lasers in medicine, especially in the treatment of diseases implies more investigations to understand the precious molecular mechanism of the laser effect on the human body. In the present study, the prominent role of HERC6 in response to CO2 Laser therapy of human skin is investigated. Methods: The numbers of 16 gene expression profiles before and after the treatment with the CO2 laser are downloaded from Gene Expression Omnibus (GEO), and differentially-expressed genes (DEGs) are analyzed to find the significant DEGs. Gene ontology analysis revealed that HERC6 and a set of its neighbors played a significant role in response to laser application. Results: The expression changes of 52 significant DEGs were compared via heat map analysis and 27 significant DEGs were introduced as the critical genes which are involved in response to laser irradiation. "Thymidylate kinase activity" among 9 clusters of biological terms was highlighted as an important biological process related to the identified DEGs. HERC2 was proposed as a critical DEG which was related to several essential cellular processes in response to laser application. Conclusion: The findings from the present study indicate that HERC6 and the numbers of its first neighbors are involved in the essential cellular response to laser therapy of human skin.

Abstract
BACKGROUND AND OBJECTIVES Alopecia areata (AA) is an autoimmune disease characterized by T cell-mediated attack on the hair follicle. Although there are a wide range of therapies, the majority of them are not satisfactory due to side effects or limited efficacy. In this study, we sought to evaluate the efficacy, influence factors, and safety of 308-nm excimer lamp with minoxidil in the treatment of AA. STUDY DESIGN/MATERIALS AND METHODS This was a prospective, single-blinded, self-control study, using 308-nm excimer lamp with minoxidil for the treatment of AA. One selected alopecia lesion was divided into the control and treated side. Topical minoxidil (2% solution) was used on both sides, but 308-nm excimer lamp was only added to the treated side. The primary endpoint was the discrepancy of hair growth on each side. RESULTS A total of 38 patients (24 males and 14 females) with AA were enrolled in this study, and 34 of them (21 males and 13 females) completed the whole treatment. Thirty-two (94.2%) patients achieved clinical response, and 21 (44.1%) patients achieved with >50% hair regrowth on the treated side after a 12-week treatment. The hair number and diameter on the treated side had significantly increased compared with the control side with statistical differences. Hyperpigmentation and erythema occurred on the treated side of all the patients but they were considered tolerable. Patients of younger age or with smaller area of lesion had better effect. CONCLUSIONS The 308-nm excimer lamp with minoxidil therapy can be considered as an effective and safe treatment for single or multiple AA. Lasers Surg. Med. © 2020 Wiley Periodicals, Inc.
