Dr. Miracle's Intensive Spot Serum. If your hair has suffered severe damage, apply Dr. Miracle????s Intensive Spot Serum massaged into areas of the scalp where slow growth is a problem. Apply to the hair itself if there is severe breakage, as well as dry, split ends. Just a small amount massaged into those areas most damaged, twice a day, will really accelerate the healing process. It also prevents frizziness, seals in moisture and shine.
