990-1000 / 1000+ resultsresearch Towards A Free Radical Theory Of Graying: Melanocyte Apoptosis In The Aging Human Hair Follicle As An Indicator Of Oxidative Stress Induced Tissue Damage
Oxidative stress causes hair to gray by damaging and killing pigment cells.
research The Peripheral Clock Regulates Human Pigmentation
Certain genes control the color of human hair by affecting pigment production.
research Repigmentation Through Melanocyte Regeneration in Vitiligo
UV light can help stimulate the growth of new pigment cells from hair follicles in people with vitiligo.
research Vitiligo: Autoimmunity And Immune Responses
Vitiligo is caused by the immune system attacking skin pigment cells.
research Paracrine Secreted Frizzled-Related Protein 4 Inhibits Melanocyte Differentiation in Hair Follicle
A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.
research Subclinical Speckled Perifollicular Melanosis of the Scalp
The scalp has a natural speckled pattern of increased pigment around hair follicles, possibly linked to local hormone production.
research The Psychology of Gray Hair
Stress can cause hair to turn gray by depleting pigment-producing cells through the release of a stress hormone.
research Culturing of Melanocytes from the Equine Hair Follicle Outer Root Sheath
Researchers successfully grew horse skin cells that produce pigment from hair follicle samples.
research Scalp Micropigmentation
Scalp micropigmentation is a process where tiny dots of pigment are tattooed onto the scalp to create the appearance of a shaved head or fuller hair.
