The document concludes that various childhood hair and nail disorders exist, some may improve on their own, and advances in genetics and immunology could enhance treatment and counseling.

The study concluded that a protein important for hair strength is regulated by certain molecular processes and is affected by growth phases.

Researchers extracted tiny keratin filaments from human hair by unzipping its outer layer.

Most hair loss in children is caused by a few common conditions and is easy to diagnose, but rare types require careful evaluation.

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

Keratin genes change gradually during skin cell development and should be used carefully as biomarkers.

The research identified key proteins and genes that may influence wool bending in goats.

STAT3 signaling is important for healthy skin and hair follicles, and its disruption can lead to skin conditions like atopic dermatitis.

Androgens reduce BMP2, which weakens the ability of certain cells to help hair stem cells become different types of cells.

Researchers identified genes and proteins that may influence wool thickness in sheep.

Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.

Found 32 genes linked to male baldness, affecting hair growth and stress-related pathways.

Gambogic Amide helps maintain hair color and promotes hair growth.

Different body parts have varying levels of certain hair follicle markers.

The Hairless gene is crucial for hair cell development, affecting whether skin cells become hair or skin and oil gland cells.

Human dermal fibroblasts help microvascular endothelial cells grow, but not vice versa.

Human hair contains more glycosaminoglycans in children than adults, and these compounds decrease with age, possibly affecting hair thickness.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.

The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.

SA linked to mitochondrial issues and oxidative stress, while AGA involves disrupted hair growth genes.

The "Two-Cell Assemblage" assay is a new, simple method to identify substances that may promote hair growth.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

The "Punch Assay" can regenerate hair follicles efficiently in mice and has potential for human hair regeneration.

The document concludes that cosmetics need biocompatible, eco-friendly ingredients due to aging populations and demand for effective products.

Feathers are useful for researching growth, regeneration, and the effects of treatments like chemotherapy on hair loss.

The document explains how to create detailed biological pathways using genomic data and tools, with examples of hair and breast development.

Some horses lose hair without inflammation or itching due to various conditions, and while mainly a cosmetic issue, diagnosis requires examination and biopsies, and breeding is not advised if it's hereditary.

Scientists can mimic hair disorders by altering genes in lab-grown human hair follicles, but these follicles lack some features of natural ones.

UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.
