6 Ounces. My Dr. Miracle's Intensive Spot Serum Treatment is my prescription for your scalp areas that need extra help, and for your hair areas where split ends, slow growth and breakage are a real problem. "Feel It" Formula tingling sensation should be used directly on your scalp where you have the most slow growth problems. Stimulates blood flow to the scalp. Spot serum ends breakage and split ends. Spot Serum also shines, conditions, strengthens and moisturizes. Spot Serum continues to work even after you stop feeling it. My most intensive treatment ever. Smile...it's working.
