Since conditioner coats the hair, it is best to use it last. If you use conditioner first and then a treatment, nutrients will not be absorbed into the hair already coated by the conditioner. Therefore, you should nourish your hair with a treatment first, and then use conditioner to properly coat it and prevent the nutrients from escaping.
