I am 21M and suffering from prematured gray hair from the age of 18. None of my family member suffered from gray hairs at this age. I'm a Veg.
I'm looking for real-world experiences from people who have used products containing Kerablak, Darkenyl, or Greyverse to treat premature gray hair.
Did you notice any reversal of gray hairs, or did it only slow down new grays?
How long did it take before you saw any results?
Which product or brand did you use, and at what concentration (if known)?
Did the results last after you stopped using it?
Were there any side effects or disappointments?
