Hair moisture behavior helps tell apart different chemical treatments and reveals insights into hair structure.

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.

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

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.

Aging causes hair to gray and thin, with the timing of graying varying by race, and factors like oxidative stress and genetics can lead to hair loss.

Certain genes are more active in baby scalp cells and can help grow hair when added to adult mouse skin cells.

Compound 15a was effective in inhibiting 5α-reductase.

Alcoholic solvent improves selectivity in key intermediate for finasteride and dutasteride synthesis.

Modern hair restoration techniques can effectively treat hair loss and provide natural-looking results.

Improving artificial vascular grafts requires better materials and surface designs to reduce blood clotting and support blood vessel cell growth.

Calreticulin has roles in healing, immune response, and disease beyond its known functions in the endoplasmic reticulum.

AGA causes hair loss by shrinking hair follicles due to DHT binding, and can be treated with finasteride and minoxidil.

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

Wool follicles are complex, involving interactions between different cell types and structures.

Beta-sitosterol has potential health benefits but needs more research to fully understand its effects and improve its use in treatments.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Disruptions in hair follicle fibroblast dynamics can cause hair growth problems.

DNA variants can predict male pattern baldness, with higher risk scores increasing baldness likelihood.

Polyamines help fix DNA damage accurately in cells.

Mice lacking Insig proteins had hair growth problems due to cholesterol buildup, but this was fixed by the drug simvastatin.

Some natural compounds can protect fish ear cells from damage by certain antibiotics without affecting the antibiotics' ability to fight infections.
