Not Today Grey’s formula is well within the tolerable upper intake level for each ingredient and was designed to work in conjunction with most multivitamins, but we always recommend you consult with your healthcare provider to confirm that the combination will remain within the tolerable limits for your body.

Not Today Grey is a daily supplement that delivers vitamins, minerals, and antioxidants that help slow and even repigment grey hair. You may also see thicker, fuller, and healthier hair.

We recommend combining our supplement with To The Root™ — a topical hair-growth serum that acts directly on your roots to slow grey hair growth and encourage repigmentation. Shop The System for a convenient bundle containing these two core grey hair treatment products.

You should start to see improved scalp health within 1-2 months of consistently using Not Today Grey. Fuller, healthier hair starts to appear in 2-3 months, followed by less grey hair growth. Repigmentation becomes noticeable after around 4-6 months of consistent use. Results may vary. For best results, we recommend combining Not Today Grey with our topical serum To The Root™. That’s why we created our System bundle to make it easy to achieve your best hair. Your hair health is important to us. We offer 25% off with auto replenish to help you reach your hair health goals.

All of our topical products are safe to use while pregnant or nursing. As with every supplement and out of an abundance of caution, we recommend that you consult your doctor before use if you are pregnant or nursing.

Not Today Grey is very effective at maintaining pigment production, repigmenting grey hair, and promoting thicker, fuller hair. The hair on our head and beard is called terminal hair, our body hair is called vellus hair. The difference between terminal and vellus hair is the length of time that each will grow. Vellus hair grows for a shorter time frame, on average 2mm long. Terminal hair continues to grow much longer for a period of 3-7 years and is more likely to be affected by the Vitamins, Minerals and Antioxidants in Not Today Grey. We haven't had any reports of increased or more pigmented hair growth in other areas of the body.
