Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as just 'волос' (hair) or 'луковица волоса' (hair bulb). The follicle is the entire sac, not just the bulb or the strand. The precise equivalent is 'волосяной фолликул'.
Common Mistakes
- Using 'hair follicle' to refer to the hair strand itself (e.g., 'She cut her hair follicles').
- Pronouncing 'follicle' with stress on the second syllable (/fəˈlɪk.əl/). Correct stress is on the first syllable.
- Confusing 'follicle' with 'pore' (a pore is an opening, a follicle is a tube/sac).

FAQ
Frequently Asked Questions
Plucking removes the hair shaft and may damage the follicle bulb, but rarely removes the entire follicle structure from the skin.
Follicles can be permanently damaged or destroyed (e.g., by scarring, certain diseases), leading to permanent hair loss in that spot.
A hair follicle is the tube that produces the hair. A sebaceous gland is usually attached to it and secretes oil (sebum) into the follicle.
Tiny muscles attached to hair follicles contract in response to cold or emotion, pulling the hair upright and causing the skin around the follicle to pucker.
