In this study, chitosan hydrogels and delivery systems showed promise in supporting skin recovery post-laser procedures, enhancing topical treatments for acne and melasma, and improving hair density in scalp applications, but limited study sizes and formulation variability restrict generalizability.

In this study, baseline neutrophil-to-lymphocyte ratio (NLR) was associated with predicting early trichoscopic response in patients undergoing PRP-based treatment for non-scarring alopecia.

This review discusses the mechanisms, scientific support, and FDA clearance of photobiomodulation mask devices but reports no new research findings.

This study investigated the photoprotective properties of Brazilian pepper tree extract against UV-induced damage in skin cells, reporting that it enhanced expression of genes relevant to skin health and showed superior activity compared to standard antioxidants.

This preliminary study suggests that hyperbaric oxygen therapy may improve scalp health and follicle activation in healthy adults, with subjective assessments showing significant improvements despite mixed objective findings.

This systematic review synthesizes evidence from the past 20 years to highlight the potential of exosome-based therapies from stem cells and plants in improving cutaneous repair, skin aging, and challenging dermatological conditions through mechanisms like immunomodulation and collagen remodeling.

In this preliminary study, HBOT appeared to improve subjective measures of hair and scalp health in healthy adults, but objective changes in follicle density and hair properties were not statistically significant.

Skin organoids can mimic human skin responses to injury and inflammation, making them useful for studying skin diseases and testing treatments.

This review summarizes research on scar formation and inhibition mechanisms, discussing emerging therapies like gene therapy and stem cell treatments, but notes ongoing challenges for clinical application, including treatment personalization and outcome sustainability.

In this study, oral administration of wheat sprout extract significantly protected rats against skin damage caused by acrylamide exposure by enhancing antioxidant defenses, reducing oxidative stress, and preserving skin structure, highlighting its potential as a sustainable protective agent against environmental skin toxins.

This review discusses the clinical efficacy, safety, and mechanisms of Autologous Micrografting Technology for androgenetic alopecia, reporting significant short-term improvements in hair density and thickness.

In this exploratory randomized controlled trial, participants using a combination of Centella asiatica-derived extracellular vesicles with recombinant growth factors showed significant improvements in hair thickness, density, length, and reduced hair loss and scalp sebum content after 56 days, compared to placebo.

This study describes an innovative hair restoration technique combining traditional hair transplantation with autologous stem cells, which enhances hair density and quality by optimizing transplantation results through the treatment of both native and transplanted follicles.

This review found that exosome therapy shows the most promise for hair regrowth and safety in treating androgenetic alopecia, surpassing platelet-rich plasma, while minoxidil remains less effective but more accessible. Further research is needed to refine these treatments.

This review highlights the potential of olive mill wastewater as a sustainable source of cosmeceutical ingredients with antioxidant, anti-inflammatory, and dermatological benefits but reports no new clinical findings.

This review discusses the dermatological potential of olive mill wastewater as a sustainable source of high-value cosmeceutical ingredients but reports no new clinical results.

In this study, micrografting technology was found to potentially shorten healing time compared to other grafting techniques, especially in treating burns, though results showed high heterogeneity and a risk of bias.

This review synthesizes data suggesting that managing inflammation and oxidative stress may enhance the effectiveness of PRP therapy for hair regeneration, though standardizing PRP protocols remains challenging.

In this study, the researchers found that the water-soluble fraction of Rhus semialata gall extract and its component Penta-O-Galloyl-β-D-Glucose promoted hair growth in human dermal papilla cells, and clinical trials supported these findings, showing improved hair density and appearance compared to placebo.

Veratric Acid may help promote hair growth and reduce hair loss.

This study explored the effects of TTFE on male androgenic alopecia, finding that topical application increased hair density, follicular diameter, and scalp hydration while reducing water loss and sebum production in a 12-week trial.

This scoping review suggests that physiological differences in skin structure may affect how individuals with different skin tones respond to pressure ulcer development, emphasizing the need for targeted prevention strategies.

Two L-PRP treatments improve hair density in mild to moderate alopecia.

In this study, injectable platelet-rich fibrin (I-PRF) was found to be more effective than platelet-rich plasma (PRP) at improving hair growth outcomes and patient satisfaction for androgenic alopecia.

This study found that a hair serum with plant-derived ingredients significantly reduced hair loss in women with chronic telogen effluvium over 16 weeks, and was well-tolerated, leading to improved hair characteristics and quality of life compared to a control group.

This study observed that six sessions of injections using a stabilized hyaluronic acid compound improved hair thickness, shine, density, and reduced hair loss in volunteers with moderate androgenetic alopecia, with excellent treatment tolerability and high satisfaction reported by 88.5% of participants.

In this interventional study on female-pattern hair loss, researchers found that fractional CO2 laser therapy alone improved hair growth, as evidenced by increased hair count, thickness, density, and patient satisfaction compared to saline controls. However, the precise mechanisms behind these effects require further investigation.

The study investigated immune cell patterns around the hair follicle infundibulum in androgenetic alopecia, revealing significant differences in immune signatures between patients with AGA and control donors, specifically noting an enrichment of CD4 cells in the patient group.

This narrative review reports that well-selected plant extracts and their active compounds may improve hair health by promoting hair growth and preventing hair loss, potentially aiding in developing targeted therapies for alopecia.
