I am 34 now but started going silver when I was 18. Taking chlorella and spirulina have both reduced my grey hair dramatically. I tend to only take it in the warmer months in my smoothies. My hairdresser didn't believe me, was adamant that nothing reverses silvers, but I plucked one off my head and showed him the proof from the strand that was dark at the root and silver on the end, and he knows I don't dye my hair, and he was amazed! Says I am "a miracle of science."
