In this study, using a 15-day regimen combining a scalp scrub and serum significantly improved dandruff and scalp health in participants, reducing flaking, increasing hair density and thickness, and enhancing hydration and overall scalp appearance.

In this study, QR 678 and QR 678 Neo formulations containing growth factors and peptides were found to be safe in vitro and promoted hair growth in vivo in an animal model, suggesting their potential as treatments for alopecia, including secondary alopecia post-chemotherapy.

This review outlines the various processes activated by the peptide GHK-Cu in tissue remodeling and reports improvements in skin and wound healing but notes a need for further study to fully understand these mechanisms.

This review reported that while glycyl-L-histidyl-L-lysine tripeptide copper complex (GHK–Cu) has limited skin permeation when used alone, liposomes may enhance its absorption, but there is limited research on this aspect, highlighting a need for further studies.

This study found that a combination of topical and oral treatment led to greater improvements in hair density, thickness, and anagen/telogen ratio in patients with androgenetic alopecia compared to topical treatment alone, with significant benefits observed over a 3-month period.

This review discusses both conventional and new pharmaceutical treatments for hair loss, as well as various natural and herbal remedies, but reports no new clinical results.

This review reported that tripeptides, such as GHK and KdPT, show promise in enhancing wound healing through multiple mechanisms, including promoting cell migration, collagen deposition, and angiogenesis, while offering antimicrobial and anti-inflammatory benefits for both acute and chronic wounds.

This review discusses plant-based alternatives to retinoids for dermal antiaging and hair health, highlighting roles for cytokinins and phytoestrogens and reports no new results.

In this study, peptide nanofiber gels RG and RJ significantly accelerated the healing of deep second-degree burn wounds in vivo, with greater wound closure rates and enhanced tissue regeneration compared to controls, attributed to increased angiogenesis and reduced systemic inflammation.

This study found that the ALAVAX complex, containing 5-ALA and GHK peptide, may increase hair count in male pattern hair loss patients over 6 months without adverse events.

This study found that using the "Khalgai" hair care products enriched with copper and zinc for 28 days led to increased hair density, diameter, and follicular unit count in women, indicating improved hair morphology.

This study found that using Urtica cannabina extract shampoo led to increased levels of copper, zinc, and iodine in the scalp hair of Mongolian women, along with improvements in hair growth, diameter, and density compared to a regular shampoo.

This review discusses various potential adverse effects of common oral vitamin and mineral supplements used in dermatology and highlights lesser-known issues like hematologic and neurologic effects from zinc.

This study found that people with chronic telogen effluvium had lower hair and serum iron levels and higher serum copper levels compared to healthy controls.

This review examines recent approvals and emerging treatments for androgenetic alopecia, discussing newly approved drugs like Propecia and Rogaine Extra Strength 5%, but without presenting new clinical results.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.

Five monthly sessions of minoxidil-dutasteride-copper peptide tattooing significantly improve hair regrowth in men with androgenetic alopecia.

In this study, researchers developed a nanocomposite microneedle patch containing copper/zinc dual-doped silica nanoparticles, which release substances to promote hair follicle regeneration by targeting various pathophysiological aspects of androgenic alopecia, presenting an effective anti-hair loss treatment strategy.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

The researchers reported that a newly developed ionic liquid-based microemulsion significantly improved the local delivery of copper peptides in mice, enhancing hair growth-related factor activation while offering a safer, non-invasive alternative to existing treatments for hair loss.

In this study, the researchers developed a novel wound dressing incorporating copper-doped calcium silicate and curcumin, which significantly promoted nerve and blood vessel regeneration in deep burn wounds, emphasizing the crucial role of bioactive chelation in neuralized skin repair.

In this study, researchers created a novel fibrous membrane inspired by ancient Chinese medicine that effectively promotes hair follicle regeneration and wound healing in deep burn injuries by releasing quercetin, copper, and silicon ions.

The microneedle arrays effectively promote wound healing and have potential for clinical use.

This study observed that patients with various types of hair loss had significantly lower serum zinc levels compared to healthy controls, suggesting zinc disturbance may play a role in the condition.

This study found that patients experiencing hair loss had significantly lower serum levels of zinc and copper compared to healthy controls.

This study identified that copper depletion in dermal papilla cells reduced hair growth by boosting ROS levels, but ROS scavengers like NAC and ascorbic acid partially alleviated this effect.

This review explores the potential of metal nanoparticles as innovative treatments for alopecia, highlighting their effectiveness in promoting hair regrowth, enhancing drug delivery, and modulating gene expression while also assessing the related experimental methodologies and regulatory considerations.

This review concluded that the efficacy of cosmeceutical hair serums for addressing hair loss lies in their use of bioactive peptides and plant compounds, like flavonoids and sterols, that target eight key contributing factors identified in hair loss conditions.

This review examines how incorporating various polymers and active ingredients into polyurethane dressings can enhance their properties and adaptability for better wound repair and regeneration, suggesting a promising direction for developing advanced functional dressings.
