We recommend using Divi's Scalp Serum daily for 3 continuous months to see best results. That said, you may experience benefits after just a few uses including a happy scalp, more hydration and less product buildup. Why am I not getting the tingly feeling? Some users have more sensitive scalps than others. You?ll get the same benefits from our scalp serum with or without the tingly feeling. Tingling may feel stronger when applied right after showering to clean, damp hair. Are there any side effects? If you notice any unusual symptoms, stop using the product immediately and consult your doctor. Can I use styling/heat products with Divi's Scalp Serum? Yes! Our Scalp Serum is designed to fit into your normal hair maintenance and styling routine. Is Divi's Scalp Serum right for me? Our Scalp serum is good for those with itchy, dry scalps, those with hair shedding/thinning, scalps with a lot of product or oil buildup, those who wear tight hairstyles, those with extensions, and anyone looking to start a cleansing scalp routine.
