Did you mean Infundibulum?

GlossaryInfundibulum

funnel-shaped upper part of a hair follicle

The infundibulum is the funnel-shaped upper part of a hair follicle, located just below the opening of the follicle at the skin's surface. It plays a crucial role in guiding the hair shaft as it grows and emerges from the skin, and it also serves as a pathway for sebum and other substances to reach the skin's surface.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
