If you start our course of Hair Health Gummies, and start seeing results in your hair, skin and nails it is recommended that you continue eating gummies. However, if you top eating the hair health gummies then rest assured you will not face any side effects. If you happen to maintain your diet well then you will not face the issues but if not, the deficiency in the diet can come back and the problems like hair fall, dull skin and brittle nails can come back.
