This review explores the extraction, characterization, and skin cosmetic effects of phenolic compounds and pigments from marine macroalgae, highlighting their documented benefits for skin health, such as whitening, moisturizing, photoprotection, and anti-aging effects, without adverse health impacts.

This study found that petroleum ether extract of Glycyrrhiza glabra prevented alopecia in testosterone-treated male rats, demonstrating effects comparable to the standard treatment finasteride.

This study found that using a combination of Alginate-TEMPO-oxidized cellulose nanofiber-α-tocopherol membranes and Pluronic-α-tocopherol hydrogels facilitated better wound healing in diabetic rats through enhanced angiogenesis and no observable toxicity compared to using each treatment individually.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

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 using composite alginate hydrogels containing Aloe vera, CMC, and tragacanth can improve the encapsulation efficiency and protect pumpkin seed protein hydrolysates from degradation during simulated gastrointestinal digestion, potentially increasing their applicability as functional food components.

In this study, a new formulation of all-trans retinoic acid bound to polyvinyl alcohol showed reduced skin inflammation and sustained drug release for up to six days compared to free ATRA in vitro and in vivo.

This study found that incorporating a block copolymer significantly alters the size and morphology of niosome drug delivery systems made of non-ionic surfactants and cholesterol, affecting their stability.

Polyquaternium-64 helps damaged hair look healthy again.

This study identified pantolactam based compounds as effective topical antagonists of the androgen receptor, reducing sebum components in a hamster model.

This study isolated highly pure oleanolic and maslinic acids from olive milling residues, exploring their chemical reactions, including the formation of finasteride precursors.

This study synthesized and characterized new 2-hydroxypyrrolidine/piperidine derivatives using FeCl₃·6H₂O as a catalyst, but it reports no biological or clinical results.

This study found that 88% phenol treatment significantly improved texture, pigmentation, and density of hair regrowth in alopecia areata patients over nine weeks, with 78% showing a good to excellent response.

This study found that incorporating Canavalia ensiformis lectin into alginate and carboxymethylcellulose films enhanced angiogenic factor expression, suggesting these biopolymer films could be an effective alternative for wound treatment.

This study found that a poly herbal hair oil formulation significantly promoted hair growth in a pre-clinical mouse model.

This review assesses the benefits and limitations of various supramolecular hydrogels, including polymeric and peptide-based types, for wound healing, but reports no new clinical results.

This study suggests that DPCP treatment can be effective and safe for severe alopecia areata in children, with maintenance therapy potentially reducing relapse rates.

This study found that glycerol most significantly influenced the spreadability and initial viscosity of a saw palmetto anti-hair loss cream, while PEG 400 predominantly affected viscosity changes over time.

This study found that estetrol (E4) significantly prolonged the anagen phase and increased hair matrix keratinocyte proliferation in cultured human hair follicles, suggesting its potential as a treatment for female pattern hair loss.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

In this study, extracts from the bark of Albizia saponaria, particularly the ethyl acetate fraction, showed significant antioxidant activity, potentially due to its high phenolic and flavonoid content, suggesting its usefulness as a source of antioxidants for pharmaceutical formulations.

This study demonstrated that imidazole-based ionic liquids, particularly [Emim]DEP, effectively dissolved yak hair keratin, maintaining its structure better than other tested solvents, and also performed well on human hair and goat wool, with consistent performance even after five recycling cycles.

This study found that Plinest injections improved skin hydration and elasticity in the face, neck, and décolleté and were well-tolerated, with high patient satisfaction over a 4-month follow-up.

This study developed a new competitive 5alpha-reductase inhibitor with an IC(50) of 0.84 microM using a novel chemical structure.

This review discusses the potential of Pluronic F127-derived hydrogels for wound healing, examining their applications in various wound types and exploring underlying mechanisms and their interaction within the wound microenvironment.

In this laboratory study, researchers developed a genipin-stabilized asymmetric PLA/gelatin scaffold that mimics skin architecture, supports fibroblast proliferation, and closes scratches effectively, suggesting its potential for epidermal-dermal regeneration and applications in sensing or drug delivery.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.
