Did you mean Dilated Hair Follicles?

Glossary Dilated Hair Follicles

enlarged openings in skin where hair grows

Dilated hair follicles refer to hair follicles that have become enlarged or widened. This condition can be caused by various factors, including excessive sebum production, accumulation of dead skin cells, or certain skin conditions like acne. For professionals, it's important to note that dilated hair follicles can sometimes lead to secondary issues such as folliculitis or contribute to the appearance of large pores on the skin.
