Oil treatment with cones
I searched but didn't find an answer to this so thought I'd ask here. I subscribe to a monthly makeup/skincare club where they send you a package every month that has different things in it. Well this month I'm getting a hot oil treatment among other things. When I checked the ingredients, they included cones. My question is, how do I go about using this oil treatment? I would have to use a shampoo with sulfates to remove the cones so is it even worth it to use this type of oil treatment?
