How exactly should I use this oil for hair oiling before washing, and how long should I leave it on? — Vegetable cosmetic oil Burdock, 50 ml "AromaSaules"

Hair oiling before washing is a traditional way to use burdock oil. Apply the oil directly to dry hair lengths, focusing on ends and any dry or brittle areas. Use a small amount initially—one to two pumps is often enough for shoulder-length hair. For fine hair, less is better to avoid weighing it down; for thick, coarse, or very dry hair, you can use a bit more. Massage it gently from mid-lengths to ends. You don't typically need to apply it to the roots unless you are specifically doing a scalp treatment.

There is no strict timing rule, but leaving it on for at least 30-60 minutes allows the oil to act as an emollient, forming a light protective film to help reduce moisture loss. Some people leave it on overnight with hair wrapped. Afterward, wash your hair thoroughly with your regular shampoo, as richer oils may require two washes to remove completely, leaving hair feeling softer and smoother. Doing this treatment once a week is a common frequency.
