Your Hair Isn't Going Gray — It's Bleaching Itself From the Inside
Gray hair isn't a pigment shortage — it's an oxidative stress problem. As you age, your follicles lose the enzyme catalase, letting hydrogen peroxide build up and shut down melanin production. Gray Guard attacks this from both sides: catalase to break down the H2O2, plus L-Tyrosine and PABA to feed the melanin pathway directly.

The Chemistry Starts
−- Catalase begins working against H2O2 buildup in your follicles
- L-Tyrosine and PABA start supplying the melanin pathway
- Nothing visible yet — pigment change happens at the root, not the strand
Working at the Root
+New hair forming at the follicle is now growing with full pigment support. You can't see it yet — hair only grows about half an inch a month.
Check Your Roots
+The first place progress shows: incoming regrowth at your part line and temples. Existing gray strands won't change — it's the new growth that counts.
The Grow-Out Window
+Early PABA research reported pigment response in the 2–4 month range. By now you've got a full inch of supported regrowth to judge for yourself.
Keep the Line Moving
+Pigment support is cumulative — every month of use is another month of supported growth. Stop, and H2O2 starts building back up.
