We've taken a look at using rosemary extract in hair care products - do the same thing for white willow bark. Dissolve it in warm water and use in the cool down phase (or if you're using the liquid extract, just add it - it doesn't need dissolving). For someone with really oily hair or scalp - almost an excessive amount - consider adding it at 1% in one of the products and see how they like it before adding it to every product.
The point of a leave in conditioner is to offer conditioning and moisturizing to both your hair and scalp, with some detangling thrown in to help with combing. Include white willow bark extract at 0.5% in the cool down phase to help with really oily or dandruff-y scalps.
Here's a quick recipe for a scalp refresher for someone with dreads or a particularly dry scalp. I've added the minty ingredients for a slight tingle and cooling sensation - if you don't want that tingle, then use non-minty essential oils and hydrosols.
