This study reported that atelocollagen enhances collagen synthesis and reduces oxidative stress in aged skin by increasing glycine uptake through GlyT1, resulting in improved skin elasticity and collagen density in aged mice, with effects superior to glycine alone.

In this animal study, applying a combination of inositol-stabilized arginine silicate complex and magnesium biotinate promoted hair growth but not nail growth.

Certain micronutrients may improve hair and nail health, but more research is needed to confirm their benefits.

This study observed that social media significantly influences biotin supplement use among young women in Pakistan, often outweighing professional medical advice.

This systematic review found no consistent evidence supporting the effectiveness of biotin supplementation for alopecia treatment unless there is a documented deficiency.

In this study, researchers using a UVB-induced mouse model identified the gene COL7A1 as a novel marker for hair luster, finding that minoxidil, caffeine, and biotin effectively restored its expression, indicating potential therapeutic strategies.

The study developed herbal hair gummies using ingredients like fenugreek, amla, and bhringraj, alongside folic acid, zinc, and biotin, concluding they are palatable, meet quality standards, exhibit antioxidant properties, and may effectively enhance hair growth and reduce hair loss.

In this clinical study, a vegan collagen builder (VEGCOL™️) was shown to safely and effectively improve hair growth, skin smoothness, wrinkle reduction, and joint pain relief in adults, with enhancements varying by dose over a 60-day period.

This study explores the critical role vitamins A, B7, C, D, and E play in regulating hair growth and protecting against damage, emphasizing their potential in addressing hair issues linked to nutritional deficiencies.

The researchers reported that an oral supplement containing hydrolysed fish-origin collagen, taurine, cysteine, methionine, iron, and selenium significantly improved the effectiveness of anti-hair loss treatments in people with androgenic alopecia or chronic telogen effluvium after 12 weeks, compared to drug treatments alone.

Eating a balanced diet with the right vitamins and minerals is important for healthy hair, but too many supplements can be harmful.

Experts discussed hair care, genetic hair defects, hair loss treatments, nail surgery, lupus treatments, skin infections, and cosmetic allergies.

This study found that intradermal administration of PRP combined with oral biotin significantly increased hair regrowth in men with androgenetic alopecia, without notable side effects.

This study found that non-thermal plasma treatment increased epidermal thickness and dermal collagen density in mouse skin tissue without causing damage, potentially promoting growth factors and tissue remodeling.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

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 study found that grafting split-thickness human skin onto nude mice produces scars that mimic hypertrophic scar characteristics in humans, offering a useful model for studying scar formation and treatments.

This study found that mesenchymal stem cells, especially when injected intradermally, significantly accelerated wound healing in rats compared to chitosan treatment.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This study found that engineered skin substitutes made with skin-derived precursors and epidermal stem cells can regenerate hair follicles after grafting into nude mice.

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 study observed that M. domestica larva-derived chitosan and gut extracts enhanced wound healing and collagen deposition in both immunocompetent and immunosuppressed mice, indicating potential benefits for combined therapy.

The moisturizer with phytol improved skin texture and reduced fine wrinkles better than the moisturizer without it.

This study found that dietary supplementation with collagen, chondroitin sulfate, low-molecular weight hyaluronic acid, Pycnogenol®, and coenzyme Q10 significantly improved skin hydration, elasticity, nail hardness, and hair condition in patients with age-related dermatological changes after 12 weeks.

This study found that experimentally induced hypothyroidism in rats is associated with impaired skin structure, but topical application of triiodothyronine (T3) improved these changes to resemble normal skin.

This review reports that collagen as a nutraceutical shows promising results for improving skin health in estrogen-deficient women, but more research is needed for scalp hair, nail health, and optimal dosing of curcumin and glutathione.

This study concluded that both ozonated oil and Centella asiatica extract effectively accelerated wound healing in mice through different mechanisms, with the former enhancing early-stage inflammation and the latter promoting collagen deposition and regenerative healing.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.
