Q: How do you use a hair oil applicator?
A: Fill the bottle, then part the hair in sections and run the comb head along the scalp, squeezing gently as you go. The teeth deliver oil directly to the roots rather than over the top of the hair.
Q: Can you use a hair oil applicator with any oil?
A: Most lightweight oils and serums pass through comfortably. Very thick or butter-based treatments can clog the head, so those are better applied by hand.
Q: How do you clean a hair oil applicator?
A: Rinse the head and bottle with warm soapy water after use and let it dry fully. Oil left in the chamber goes rancid over time.
