Good for roots.
on 19 February 2014
Negatives - it's quite thick and messy to apply. Not sure how long it lasts, but the effort is similar to actually dying your hair yourself, so it might not be worth it if it only lasts one or two washes. Spread it quite thinly over all of my hair (like putting on shampoo) and didn't really notice a difference. My hair feels a little dry after using it.
Positives - I really concentrated a thick paste on my (blonde) roots and it has actually made a huge difference! They're still noticeable, but only if you really look. It also blended really well with my colour, despite looking a lot redder than my hair when I was applying it.
Definitely a great quick fix for your roots, but I wouldn't bother using it for a full head tint.
