How should I use this walnut oil — as a leave-in, a pre-wash treatment, or both? — Restorative nut oil for breaking hair 3x15 ml - DNC

The oil is meant for two simple routines: as a leave-in step after washing or as a pre-wash treatment before shampooing. In both cases, a little goes a long way. Start with 2–4 drops for shoulder-length hair and add more drop by drop if the hair is longer or thick. Rub the oil between your palms first, then work it through the mid-lengths and ends. The scalp is not the target zone — the oldest, most fragile part of the hair is from the mid-lengths down, and that is where the product is most useful.

As a leave-in, apply the oil to damp, freshly washed hair. Damp strands distribute the oil more evenly and help it absorb, and the oil can then function as a light protective layer while you detangle, dry or style. As a pre-wash treatment, apply it to dry hair 20–30 minutes before shampooing. This can make your usual wash gentler on brittle lengths and makes combing easier before the wash. Many people use both at different times: a pre-wash treatment once a week and a small leave-in amount after each regular wash.

How often depends on how dry the hair feels. Two or three times per week on the ends is a reasonable starting point; if the hair is only slightly brittle, once a week may be enough. If the hair starts to look greasy or lank, reduce the frequency or the number of drops. The texture absorbs quickly, so normally nothing needs to be rinsed out, but rinsing is not a problem if you over-applied. This is a cosmetic product that improves the look, feel and manageability of the hair, not a medicine; consult a specialist before use if you have a chronic scalp condition, are pregnant or breastfeeding, or are taking medication.
