Karvatupeissa

Karvatupeissa is a Finnish locational phrase meaning “in the hair follicles.” It is the inessive plural form of the noun karvatuppi (hair follicle), used to refer to the inside of multiple hair follicles. The phrase is common in scientific, medical, and dermatological writing, as well as in descriptive texts about skin and hair biology.

In Finnish grammar, karvatupeissa signals location and refers to a plural subject: something located within more than one hair follicle. It can appear in sentences describing organisms, substances, or conditions that inhabit or affect the follicles, such as Demodex mites or microbial communities. The related illative form karvatuuppeihin would mean “into the hair follicles,” used when describing movement or entry.

Typical usage contexts include biology, dermatology, and pathology, where precise localization in hair follicles matters for understanding processes such as infestation, infection, or follicle-related skin conditions. Outside scientific contexts, the phrase may appear in textbooks, medical records, or articles discussing skin structure and hair growth.

Examples:

- Demodex folliculorum elää karvatupeissa. (Demodex folliculorum lives in the hair follicles.)

- Tutkimukset ovat löytäneet bakteerien esiintymistä karvatupeissa joissakin iho-ongelmissa. (Studies have found bacteria in hair follicles in certain skin problems.)

- Iho puhdistetaan, jotta karvatuppeihin kertyneet epäpuhtaudet vähenisivät. (The skin is cleansed to reduce impurities that accumulate in the hair follicles.)
