Did you mean Vibrissa Follicles?

GlossaryVibrissa Follicles

specialized hair follicles producing sensitive whiskers in mammals

Vibrissa follicles, also known as whisker follicles, are specialized hair follicles found in mammals that produce long, stiff hairs called vibrissae or whiskers. These follicles are highly innervated, meaning they have a rich supply of nerve endings, which makes them extremely sensitive to touch and helps animals detect their surroundings, navigate in the dark, and sense nearby objects.

community Can liver problems be associated with response to the oral minoxidil?

in Research 147 upvotes 6 months ago

Liver problems may reduce the effectiveness of oral minoxidil due to impaired SULT1A1 enzyme activity, which is crucial for converting minoxidil to its active form. This reduction in enzyme function can significantly decrease the drug's effectiveness in promoting hair growth.
