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

Hair follicles help absorb and store topical compounds, aiding targeted drug delivery.

The document concludes that accurate diagnosis of hair disorders is crucial and requires a range of diagnostic methods.

Medium lipophilic substances penetrate skin best, and adding ethanol can increase delivery to hair follicles.

Explosions don't stop hair proteins from being used to identify people.

The EDAR gene mutation leads to thinner and more deformed hair shafts.

Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Hair follicle development in cashmere goats involves dynamic changes in proteins and metabolites, with key roles for oxytocin, MAPK, and Ca2+ pathways.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

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

The document suggests a new model for evaluating public research that better captures the full value of knowledge creation and use, using PCOS research as an example.

OCT can effectively screen and diagnose various medical conditions non-invasively.
