Preserves Pigment

Supports the Growth Phase
A complex of B vitamins and essential minerals like copper and iron nourish the follicle at the cellular level, supporting a healthy growth cycle which helps hair look fuller and stronger over time.
Protects Against Oxidative Stress
Powerful antioxidants like black sesame, FoTi and selenium help reduce oxidative stress, a key contributor to greying and thinning hair.
Easy Integration
Just two capsules a day, Not Today, Grey is formulated to work with most daily multivitamins and supports pigment and the hair growth cycle without any DHT blockers.

Frequently Asked Questions
How does Not Today, Grey work?
Not Today, Grey is a daily supplement that delivers a targeted blend of vitamins, minerals, and antioxidants that support your hair’s natural pigment production from the inside out. By replenishing key nutrients that decline with age and oxidative stress, it helps slow new grey growth and, in many cases, repigment early greys. Many users also notice thicker, fuller, shinier hair over time.
For best results, pair it with To The Root® serum, which works topically on the scalp to address greying at the follicle level.
When will I see results?
1–2 months: Healthier scalp and stronger hair foundation.
