Instead he collects swatches of skin removed from behind the ear during face-lift procedures. Crucially for Tobin, the skin samples contain the miniature organs, known as follicles, that produce hair.

The skin has two types of adult stem cells: epidermal and hair follicle. Their jobs seem well-defined: maintaining the skin, ...

Hair color is determined by melanocyte stem cells that multiply inside hair follicles, previous research has shown. These stem cells get signals to mature and make proteins that produce hair color.

New research indicates exactly why hair turns gray at a cellular level. Researchers found that gray hair may be preventable or even reversible. Experts explain why hair doesn’t actually “turn ...

The NYU study showed that as the hair regrowth process aged, the number of McSC’s lodged in the follicle bulge continued to increase. At some points, this non-pigment producing follicle bulge ...

Researchers showed that cells in your hair follicles release important chemical messengers in response to gentle touches to your skin. By Veronique Greenwood When someone brushes a hand across ...

Spinach is a leafy green vegetable that is a good source of iron, vitamin A, folate, and vitamin C. Iron “helps carry oxygen to hair follicles,” explains Dr. Berry, who adds that low levels of ...

MicroRNA-205 promotes hair regeneration by modulating mechanical properties of hair follicle stem cells. Proceedings of the National Academy of Sciences , 2023; 120 (22) DOI: 10.1073/pnas ...

Each hair follicle keeps immature melanocyte stem cells in storage. When they’re needed, those cells travel from one part of the follicle to another, where proteins spur them to mature into ...

UVA's Dr. Lu Q. Le and his team have identified a previously overlooked stem cell population in the upper and middle sections of the hair follicle that plays a crucial role in hair growth.When ...
