Human hair surface varies in wettability, showing daily and monthly patterns.

Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.

Formyl-peptide receptor agonists could be new anti-inflammatory drugs.

Transcutol-containing vesicles improve minoxidil's skin penetration and hair growth promotion.

Graphene oxide helps deliver a skin healing agent over time, improving skin and hair follicle regeneration.

Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.

Dutasteride-loaded nanoparticles coated with Lauric Acid-Chitosan show promise for treating hair loss due to their controlled release, low toxicity, and potential to stimulate hair growth.

Three genes in Arabidopsis are important for plant growth and development by affecting sugar attachment to proteins.

A new method allows for controlled, long-lasting delivery of retinoic acid through the skin with fewer side effects.

The Cell Membrane Complex in hair has both water-attracting and water-repelling layers.

Changing disulfide bonds in human hair affects its melting behavior and thermal stability.

Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

Niosomes are a promising and effective way to deliver drugs through the skin.

Serum formulations were better at delivering molecules to the hair bulb than nanoparticles.

Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.

A certain surfactant sticks to human hair, making it change from water-repelling to water-attracting, which could help in hair conditioning.

FGF9 controls which receptors it binds to through a process where two FGF9 molecules join, and changes in FGF9 can lead to incorrect receptor activation.

Hair's strength and flexibility come from its protein structure and molecular interactions.

Surface and internal treatments can help prevent hair lipid loss during washing.

Lipid-coated silica nanoparticles penetrate human skin more deeply than bare silica nanoparticles.

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.

Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.

Human hair keratins can be turned into useful 3D biomedical scaffolds through a freeze-thaw process.

Four-amino acid part makes enzyme sensitive to finasteride.

The PS-b-PAA copolymer nanomicelles are effective for delivering a cancer treatment drug in photodynamic therapy.

Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.

Using longer PEG chains helps nanoparticles penetrate hair follicles better, improving drug delivery for conditions like alopecia.

Microemulsions could improve how drugs are delivered and absorbed in the body.
