This study analyzed gray hair, revealing that it differs from pigmented hair in follicular activity, oxidative balance, and structure, impacting coloring processes and necessitating adapted techniques to maintain hair quality.

Puradrop Extra Strength Gummies claim to support weight loss and boost energy using natural ingredients.

In this study, hair follicle stem cells were reported to accelerate burn wound healing and increase tissue tensile strength in rats.

In this study, a water-soluble nail strengthener containing Pistacia lentiscus and hyaluronic acid significantly improved the appearance and firmness of brittle nails in both in vitro and clinical settings.

This study found that a new eco-friendly hair crosslinking method using visible light and non-toxic chemicals caused less damage and improved mechanical properties compared to traditional thioglycolic acid treatment.

This study found that 3-aminopropyltriethoxysilane penetrates hair fibers and improves the mechanical resistance of dry hair, addressing the needs for increased body in fine hair.

This study demonstrated that incorporating human hair fiber into soft clayey soil significantly enhances subgrade strength and reduces cracking compared to unreinforced soil, as confirmed by unconfined compressive strength and CBR tests.

The MHRA announced on 11 May 2026 that it will update the product information for finasteride and dutasteride to include more details on potential psychiatric and sexual side effects, following a review of existing evidence.

This study found that testosterone therapy improved physical performance and strength in older men with low testosterone over 36 months, whether administered alone or with finasteride.

This study demonstrated that testosterone treatment increases muscle strength and alters body composition in transmen, and the addition of dutasteride does not impair these anabolic effects.

This study found that using electronic healthcare record data can provide valuable early insights into the clinical context of about half of the new safety signals evaluated within a regulatory environment.

This article examines challenges in the pharmaceutical supply chain during pandemics, highlighting issues like raw material sourcing and distribution delays, and suggests enhancements such as AI, blockchain, and public-private alliances to ensure stability and resilience.

In this study, researchers observed that using an Avena strigosa seed extract on chemically damaged hair significantly improved hair properties, including strength, gloss, and surface quality, by reinforcing keratin bonding and sealing cuticle damage.

In this study, researchers formulated an herbal hair serum with plant extracts like Hibiscus and Nigella and observed that it demonstrated acceptable physical properties and potential anti-dandruff activity, proposing it as a safe and effective alternative to synthetic hair care products.

This paper examines the rising popularity and potential benefits of rice water for hair care, noting that while it contains beneficial compounds like inositol that may increase hair strength and decrease frizz, there is still no definitive scientific proof of its efficacy.

In this study, researchers found distinct gene expression patterns in Standardbred trotters capable of racing barefoot, suggesting a genetic basis for hoof strength and identifying specific genes involved in hoof biology, which could enhance equine performance and wellbeing through targeted genetic research.

This study compared hydrolysed wheat protein, L-arginine, and hydrolysed collagen for their effectiveness in enhancing the tensile strength of heavily bleached hair.

This study suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

This study found that JAM-A modification in mouse wound models significantly promoted wound healing and fibroblast proliferation, potentially linked to increased levels of growth factors bFGF and EGF.

Testosterone boosts physical performance, grip strength, and lean body mass in older men with low testosterone.

This literature review reports that natural ingredients like lavender, peppermint, and rosemary in hair products have demonstrated potential for strengthening, moisturizing, and regrowing hair, while being more environmentally friendly and safer compared to chemical alternatives.

This study found that Wnt/β‐catenin signaling influences the hair follicle regeneration process by prompting quiescent stem cells to enter the cell cycle and is necessary for maintaining the stem cell pool.

This study found that testosterone therapy improved physical performance, strength, lean body mass, and serum cholesterol in older men with low testosterone levels, with or without the addition of finasteride.

This study found that an oral marine protein supplement significantly increased hair growth and reduced hair shedding in women with temporary thinning hair over 90 days compared to a placebo.

This study concluded that 5% minoxidil foam or solution applied twice daily is effective and safe for treating male androgenetic alopecia.

This review finds that vigorous aerobic exercise and resistance training may improve insulin sensitivity and androgen levels in women with PCOS, though more research is needed for definitive conclusions.
