If you are interested in dying your hair minus the nasty chemicals- the store LUSH has henna that is easy to use and you can order it online. I use it becasue I am 28 and sarted getting silver hair a year ago- and in my job it isnt really ok!
that being said- i have read numerous times that upping your consumption of seaweed can assist in filling mineral deficiencies that may be one of the reasons for grey hair. I just started eating more of it recently so i will see what happens
