research Dissolving microneedles incorporating kopexil multicomponent crystals for improved transdermal delivery
Multicomponent crystals in microneedles improve drug delivery for hair loss treatment.
research High-resolution structures of mutants of residues that affect access to the ligand-binding cavity of human lipocalin-type prostaglandin D synthase
Mutations in the enzyme don't significantly change how it binds to its specific substances.
research Analysis of structural changes in permanent waved human hair using Raman spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Synthesis and structure–activity studies of side-chain derivatized arylhydantoins for investigation as androgen receptor radioligands
The nature of the side chain in RU 58841 derivatives greatly affects its AR affinity, with the N-(iodopropenyl) derivative 13 showing the highest AR binding affinity, suggesting its potential for developing high-affinity radioiodinated AR radioligands.
research Structural studies of two solid steroid compounds
Androsterone and finasteride have different solid forms, with new findings correcting previous errors and identifying a new form.
research Synthesis and Structure–Activity Relationships of the First Ferrocenyl-Aryl-Hydantoin Derivatives of the Nonsteroidal Antiandrogen Nilutamide
Scientists made the first metal-based compounds from a nonsteroidal antiandrogen drug, which showed potential in fighting both hormone-dependent and independent prostate cancer cells.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Molecular modeling and structural characterization of a high glycine–tyrosine hair keratin associated protein
The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Essential Oils and Their Single Compounds in Cosmetics—A Critical Review
Essential oils in cosmetics can offer benefits but may cause allergies and should be used carefully.
research Single-cell profiling reveals a potent role of quercetin in promoting hair regeneration
Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.
research Structural & functional studies of L-PGDS and SMPDL3A enzymes in lipid signaling family
L-PGDS has specific binding sites for its functions and could help in drug delivery system design.
research Structural insights into SARS-CoV-2 spike protein and its natural mutants found in Mexican population
Mutations in the spike protein affect drug binding and effectiveness.
research Structural and dynamic insights into substrate binding and catalysis of human lipocalin prostaglandin D synthase
The research explains how a human enzyme binds and processes its substrate, which could relate to its role in biological functions and hair loss.
research Structural optimization of pep7, a small peptide extracted from epimorphin, for effective induction of hair follicle anagen
Modified pep7, named EPM peptide, effectively promotes hair growth at low concentrations and works well with minoxidil.
research Regenerative Medicine of Epidermal Structures
New treatments for skin and hair repair show promise, but further improvements are needed.
research A Multi-Technique Approach to the Study of Structural Stability and Desolvation of Two Unusual Channel Hydrate Solvates of Finasteride
Desolvation of finasteride depends on environment and technique.
research Mechanism of TAp73 inhibition by ΔNp63 and structural basis of p63/p73 hetero-tetramerization
ΔNp63α stops TAp73β from working in skin cancer by blocking its access to specific genes, not by directly interacting with it.
research Scaled Quantum Chemical Studies of the Molecular Structure and Vibrational Spectra of Minoxidil
The analysis shows where minoxidil's atoms are likely to react and describes its electronic transitions and behavior with temperature changes.
research Design of a biofluid-absorbing bioactive sandwich-structured Zn–Si bioceramic composite wound dressing for hair follicle regeneration and skin burn wound healing
Wound dressing absorbs fluid, regenerates hair follicles, and heals skin burns.
research A randomized, single‐blinded, vehicle‐controlled study of a topical active blend in the treatment of androgenetic alopecia
Redenyl lotion effectively promotes hair growth and improves quality of life for androgenetic alopecia patients.
