How are you long term users doing with this process?
Does anyone have light colored hair -- did it darken
Is there more growth or more health?
1. 10+ years
2. I have very dark hair....jet black naturally. Guess what, it darkened my hair. I can tell by my greybies. Yup it does darken over time.
3. It's both...growth and health. You get them in equal measures...at least I do.
