This study found that a nutritional supplement containing millet extract, pantothenic acid, L-cystine, and biotin significantly increased hair density, improved hair growth and appearance, and reduced hair loss by 59% in 112 healthy subjects with light diffuse hair loss over 12 weeks.

This study found that Caucasian hair experienced greater volume changes than Asian hair in various relative humidity conditions, and incorporating a peptide into climate control formulations significantly reduced hair volume, particularly in high humidity settings.

This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.

This study suggests that feeding pregnant mares protein blocks with urea is as effective as hand-fed protein supplements in supporting hair follicle development and protein status.

In this study, researchers developed cationic liposomes encapsulated with keratin to improve the recovery of UV-damaged hair, finding that these liposomes significantly improved keratin penetration and reduced protein denaturation and lipid peroxidation, resulting in smoother hair surfaces compared to keratin solution alone.

In a double-blind clinical trial, this study found that a gel containing chitosan-coated spironolactone nanoparticles effectively reduced acne lesions over 8 weeks without adverse skin effects, suggesting potential for enhanced acne treatment through targeted skin delivery.

In this study, researchers developed a polyphenol–amino acid nanozyme capable of controlled hydrogen peroxide delivery, which effectively activated hair follicles via oxidative stress in a mouse model, suggesting a potential non-pharmacological treatment for alopecia.

The extract promotes hair growth and may help treat hair loss.

This study found that ultrasonically depolymerized ι-carrageenan from Solieria chordalis yields low-molecular-weight fractions that maintain fibroblast viability and show no cytotoxicity, suggesting potential for safe use in human medicine.

This study found that a food supplement containing L-cystine, pantothenic acid, biotin, and millet extract significantly improved hair density and beauty parameters in healthy Japanese women with light diffuse hair loss after three months.

This study found that both hard and soft selenium disulphide-based detergents significantly increased triglyceride levels in human hair, suggesting enhanced sebum production with reduced lipolytic activity, but showed no significant differences between their effects.

This study reported that derivatization with 5-butylpicolinic acid improved the sensitivity for detecting testosterone and DHT in saliva using LC-ESI-MS/MS, with minimal interference from the saliva matrix.

This study found that applying the highest dose of biostimulant improved the fresh yield, leaf area, and ACO2 of hydroponically grown ‘Genovese’ basil, suggesting enhanced productivity with reduced fertilizer use.

This study reported that participants applying topical human platelet exosome extract serum experienced significant improvements in hair volume, density, scalp coverage, and overall hair health compared to a placebo, and no adverse effects were observed.

This study reported that newly developed RADA16-I peptide hybrids, with active motifs like GHK and KGHK, demonstrated improved wound healing in a mouse skin injury model without cytotoxicity, suggesting they might be effective scaffolds for tissue engineering and regeneration.

This study demonstrated potential in using specific keratin peptide profiles from human hair shafts to distinguish gender and ethnicity, suggesting it could enhance forensic investigations, though larger studies are needed.

This study suggests that a Lentinula edodes extract can improve skin barrier function, hydration, and sebum regulation, possibly by modulating vitamin D pathways, in individuals with oily and acne-prone skin.

This article reviews how biopolymers are utilized in cosmetics, highlighting their biodegradable and non-toxic properties, recent structural developments, novel applications, and safety considerations in the formulation of skin, hair, and oral care products.

This study found that a cosmetic formula containing 2% Orthosiphon stamineus leaf extract significantly reduced skin oiliness and pore size, showing better results than a formula with 1% zinc gluconate.

This study found that oral administration of naturally safe active polypeptides from marine shellfish promoted scarless dermal wound healing in mice, potentially via effects on inflammation, fibroblast activity, and the "skin-gut" axis.

Mink use L-methionine and L-cystine slightly better than natural amino acids for hair growth, but D-methionine is not effective.

This study developed a new method for detecting 30 hormones in anti-aging functional foods, demonstrating good sensitivity and reliability, and identified seven hormones in four out of 14 samples tested.

This study found that Gynostemma pentaphyllum hydrodistillate and Damulin B exert significant anti-photoaging effects in UVB-irradiated models by reducing oxidative stress, improving ECM integrity, and enhancing skin hydration and elasticity.

This study concluded that intralesional lyophilized growth factor injections are safe and improve trichoscopic hair parameters and clinical scores in patients with female pattern hair loss.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.
