In this split-scalp study, researchers observed that combining fractional CO2 laser and PRP treatment was significantly more effective in improving hair parameters in women with female pattern hair loss than using each intervention alone or placebo.

Oral collagen combined with other treatments effectively reduces hair loss and improves hair quality in telogen effluvium.

This study developed an in vitro 3D organoid model using dermal papilla spheroids and found that it enhances growth factor expression and extracellular matrix production, which could aid drug screening for hair regeneration.

In this study, fibroblasts treated with the small molecule peficitinib were reprogrammed into dermal papilla cell-like cells capable of inducing hair growth, offering a new strategy for hair loss treatment.

This study developed in vitro methods to regenerate hair follicles and erector muscles by mimicking their native structures and mechanical conditions, reconstructing hair follicle-like structures and forming muscle-like tissues.

This study found that while 450nm blue light can inhibit collagen and induce oxidative stress in dermal fibroblasts, 850nm near-infrared light may enhance metabolic activity without causing oxidative damage, suggesting potential for tailored light therapies in skin treatments.

This study found that twice-daily intradermal injections of mouse epidermal growth factor in Merino sheep resulted in dose-dependent changes in wool follicles and fibres, including induction of catagen and subsequent regeneration.

NUL-5 may boost hair growth by improving hair follicle health and structure.

This study found that combining platelet-rich plasma injections with topical 2% minoxidil for three months normalized certain immunohistochemical parameters in female patients with early-stage androgenetic alopecia.

This study reported that a novel bilayer wound dressing made from PLCL nanofibers and keratin hydrogel, loaded with FGF-2, promoted skin healing and showed potential for use in skin tissue engineering.

In this study, Korean adults with damaged hair who took 3g/day of low-molecular-weight collagen peptide GT for 24 weeks showed significant improvements in hair gloss, elasticity, and scalp elasticity compared to placebo, without any adverse events.

This study found that intradermal polynucleotide injections were linked to improvements in the appearance around the eyes and increased patient satisfaction, with minimal adverse effects, suggesting potential for further research to validate efficacy and optimize treatment protocols.

This study found that skin fibroblasts in mice arise from two distinct lineages which contribute differently to dermal structure and repair, impacting hair follicle formation during wound healing.

This study observed that the osteopontin-derived peptide FOL-005 inhibited hair growth in human scalp skin models, contrary to its hair growth promotion in mice, supporting further clinical testing for excessive hair growth treatment.

This systematic review explored the feasibility of adding skin needling to an aesthetic clinic's offerings, examining financial implications, time investment, and its integration with existing treatments. Various challenges and learning opportunities were noted, underscoring the complexity of introducing a new service.

This study found that fractional radiofrequency microneedling may be as effective and safe as intralesional corticosteroid injections for treating patchy alopecia areata, with potentially fewer side effects.

This study found that human dermal papilla cells are embedded in a basement membrane-like extracellular matrix, which is essential for their aggregation and function, as supported by evidence that Matrigel enhances dermal papilla cohesion and gene expression compared to collagen I, which promotes cell dispersion.

This study developed a 3D engineered hair follicle model that mimics the native hair bulb and may aid in drug screening for hair growth therapies.

A treatment called Cellcurin, combined with microneedling, significantly increased hair density and diameter in patients with hair loss.

This study found that recombinant human type XVII collagen (rhCOL17A1) promotes hair growth by activating the Wnt/β-catenin and SHH/GLI signaling pathways and increasing type XVII collagen expression, with significant effects observed in both cell and mouse models.

Laser treatment followed by a special hair growth solution increased hair count and thickness without side effects.

This study found that a 12-week supplementation with MePL, a solution of miliacin encapsulated within polar lipids, significantly reduced hair density in the telogen phase and improved scalp dryness and hair brightness in women with telogen effluvium.

New inhibitors may help treat hair loss by promoting fat cell growth in the skin.

A new treatment using special microneedles and a nitric oxide-releasing drug could improve hair growth and be more convenient for people with hair loss.

The treatment improved hair growth and thickness in most patients with minimal side effects.

In this study, iL-PRF injections produced significantly better clinical scores for androgenetic alopecia patients compared to controls, especially in those with more severe baseline conditions.

In this study, I-PRF, a blood-derived biomaterial without anticoagulants, was found to inhibit melanin production and reduce oxidative stress damage in a rat model of melasma, suggesting it as a safe and cost-effective treatment option.
