Oxidative stress causes hair to gray by damaging and killing pigment cells.
research Aging of Hair
Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.
research Torsional Method for Evaluating Hair Damage and Performance of Hair Care Ingredients
The torsional method effectively evaluates hair damage and the performance of hair care ingredients.
research Hair Follicle Pigmentation: Mechanisms and Factors Influencing Melanin Production
Hair color is determined by melanin produced and transferred in hair follicles.
research Hair Cycle and Hair Pigmentation: Dynamic Interactions and Changes Associated with Aging
As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.
research Elucidating Penetration Pathways Into the Hair Fiber Using Novel Microscopic Techniques
The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.
