Dr. Miracle's Intensive Healing Oil. Before or after shampooing, use Dr. Miracle????s Collection Intensive Healing Oil as a hot oil treatment. Use a heating cap or wrap the hair with a plastic cap and heavy towel for 20 to 40 minutes. I recommend you do this after shampooing while the cuticle is open and the hair shaft can really absorb the essential oils. Wash the hair again just enough to remove oil residue if you shampooed the hair before the treatment. This oil can also be used as a daily moisturizer.
