The document concludes that hair keratin-chitosan scaffolds were successfully made and are suitable for biomedical use.

Nanoplastics can penetrate skin cells, triggering inflammation and immune responses.

Trace elements like calcium, iron, and zinc are unevenly distributed in hair, while sulfur is even, and increased phosphorus and potassium levels are linked to skin reactions.

Fetal hair follicles have melanocytes with melanosomes at different stages, which are broken down into pigment particles in keratinocytes.

The study suggests a link between varicella-zoster virus and segmental vitiligo, with evidence of the virus disrupting skin pigment cells.

The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.

The CAP1 gene helps control ammonium levels and is necessary for the proper growth of root hairs in Arabidopsis.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

AE can have varied symptoms and genetic causes, but zinc therapy helps.

Hair microscopy is a simple and cost-effective method to help diagnose systemic diseases in children.

Nanocomposite patches improve drug delivery through the skin, offering controlled release and fewer side effects.

The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.

Hair lipids do not protect against humidity.

Repeated hair dyeing significantly damages hair.

Silver nanoparticles from Ziziphus nummularia leaves have better antibacterial, antifungal, antioxidant, and hair growth effects than the leaf extract alone.

Alopecic hair has more irregular structures and chemical changes than normal hair, reducing its strength.

Alopecia Areata causes significant structural and compositional changes in hair.

Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.

Grape seed oil improved hair quality the most, followed by rosehip and safflower seed oils, and reduced damage from shampoo.

Minoxidil can be effectively encapsulated in coated nanovesicles for potential drug delivery.

The nanoemulsion with garlic oil, apple cider vinegar, and minoxidil could effectively treat alopecia areata.

Combining polymers and lipids may improve antioxidant delivery for wound healing, but practical challenges remain.

Trichothiodystrophy involves brittle hair due to low sulfur amino acids, not a transport defect.

Microemulsions and nanoemulsions can effectively deliver drugs through the skin, but more research is needed to understand their differences and mechanisms.

Researchers developed a sensitive method to measure minoxidil in various products with high accuracy.

Mutations in Gasdermin A3 cause skin inflammation and hair loss by disrupting mitochondria.

Higher CO2 levels help a cyanobacterium grow better by boosting photosynthesis and carbon uptake.

The new formulation improved the skin absorption of the drug Thiocolchicoside.

Some masked palm civets in Japan have a skin disease caused by mites.

KATP channels are important for energy balance and are targeted by drugs for diabetes, hypoglycemia, hypertension, and hair loss.
