Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.
research Ultrastructural Characteristics of Neonate Scalp Hair
Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.
research Organization and Expression of Hair Follicle Genes
Hair growth is controlled by specific gene clusters and proteins, and cysteine affects hair gene expression in sheep.
research The Structure of the Amorphous Matrix of Keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
research Cross-Linked Features of Mouse Pelage Hair Resistant to Detergent Extraction
Some mutant mice have hair with abnormal cross-linking, mainly in the cuticle, not affecting other hair parts.
