What I did:
1. Shampooed and towel dried my hair
2. Applied the dye on the last two inches
3. Waited 20 mins, then applied more dye on the last 3 inches of my hair for a more gradient effect
4. Waited 15 mins then washed it out
Super easy! The dye took to my dry, porous hair quite well and made it feel really smooth at the ends. It also smelt like a sweet, fruity conditioner which was really pleasant. It's supposed to last 8 washes (about 2-3 weeks for me) and I will update this post as time unfolds. I like it as a temporary pop of color to my hair, but I wouldn't keep it! I think it will look better after some washes as the shade is a tad too dark for my liking.
I would recommend this product for those who are curious about how they would look with bright hair, but don't want to commit!
