I recently put the Schwartskopf Palette deluxe oil care color to the test, I used the shade "Smooth red violet" on my hair, and I was very nervous to put it over the mess that was my hair, because I hadn't dyed my hair in over 3 months (I was considering going back to my natural roots - but I'm a hair rehab failure.) I had serious root regrowth, as well as just generally uneven colour all over my head.

Knowing that there was a high possibility of a hair disaster - I went ahead and did it anyway. haha! I like to live dangerously.

Spoiler: It turned out even better than I could have hoped.

I was delightfully surprised at how even the coverage and colour turned out, there was no demarcation line, no hot roots, just beautiful and even colour!

Pros:

Affordable (R99 at Clicks)
Easy to use, the formula is not too thick or too runny, it's a breeze to apply
decent range of colours
Colour is true to the colour on the box
Doesn't leave your hair feeling damaged after use

Cons:

It's gentle on hair, but not ammonia free
It has a chemical smell - but not worse than your average box of dye

Overall I had a great experience with Schwarzkopf palette deluxe, and I am living my beat hair life right now!
