“Prologue targets graying at the source instead of masking it. The science behind it is genuinely sound.”
“A novel approach to hair color — it works with the follicle's own pigment cells. I've been impressed by what I've seen.”

Frequently asked questions
What's causing my hair to go gray?
Your hair's color comes from melanocyte stem cells — the cells inside the follicle that keep telling your hair to stay its natural shade. Over time, those cells lose that signal. The process starts years before you see the first gray, and for this generation it's starting earlier than it used to — the cumulative weight of chronic stress, UV exposure, and metabolic strain accelerates what genetics would otherwise pace more slowly.
Is Prologue a dye or a cover-up?
No. Prologue works with your follicle's own pigment cells rather than coating the hair shaft.
I'm only seeing a few grays. Is it too early to start?
The earlier you start, the more pigment-producing cells there are to support.
How long does it take to see results?
Most people see changes over a 12-week window, with continued improvement after.
My gray is genetic — my whole family went gray early. Does this still work for me?
Genetics set the pace, but the underlying cellular signaling is what Prologue supports.
How much does this actually add to my routine?
A few seconds. It layers into your existing wash-and-go routine.
