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

Modified pep7, named EPM peptide, effectively promotes hair growth at low concentrations and works well with minoxidil.

Glyoxylic acid straighteners cause more protein loss but have similar hair strength effects as traditional alkaline straighteners.

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.

Using both TGA and DTDG in hair straightening reduces hair damage compared to using TGA alone.

Bleaching hair changes its structure and weakens it, which is important for understanding hair damage and creating treatments.

UV radiation increases protein loss from hair and reduces hair protein quality.

Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.

K18® and Olaplex® both effectively repair bleached hair, improving its strength, smoothness, and overall health.

The new adhesive nanoparticles are effective for delivering Minoxidil to the scalp without skin irritation.

Cysteine helps maintain keratin production in skin cells even when iron is low.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

Some plants used in traditional medicine may help treat cancer because they contain proteins that can inactivate ribosomes.

Activin activation in skin cells speeds up wound healing without affecting scar quality.

Scientists found out how a specific protein in human hair cuticles behaves and is structured.

The document concludes that the human keratin gene cluster is complex, with a need for updated naming to reflect over 50 functional genes important for hair and skin biology.

Dermatologists need to understand hair products to treat hair and scalp issues better.

Cystatin M/E strongly inhibits cathepsin V and cathepsin L, important for skin formation.

A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Excessive selenium from a supplement caused toxicity but patients recovered with care.

Prostaglandin D2 blocks new hair growth after skin injury through the Gpr44 receptor.

Different hair protein amounts change the strength of keratin/chitosan gels, useful for making predictable tissue engineering materials.

S100A3 protein is crucial for hair shaft formation in mice.

Black women's unique hair characteristics and styling practices can lead to specific scalp conditions, which require early diagnosis and appropriate treatment.

Finasteride irreversibly affects human steroid 5α-reductase 2, providing insight into its catalytic mechanism and disease-related mutations.

Cat color patterns are determined early in development by gene expression and epidermal changes, with the Dickkopf 4 gene playing a crucial role.

The document concludes that there are still unknowns about the effectiveness, risks, and detection of performance-enhancing drugs, and doping remains a challenge.
