Leaves mess all over your scalp

So this product did disappoint me slightly. I was initially impressed how easy it was to get the dye onto the sponge. You give the rub a shake and the dye leaves the holder and goes onto the sponge. First impression the colour looked a good match. However when it came to apply the product I felt it cling to my scalp and made it look like I’d freshly dyed my hair and not washed my scalp properly! Even worse when I’d used this on baby hairs at the front of my head as it gave me a whole new hairline! I feel they should have better way of applying the product to your hair that doesn’t leave it clinging to your skin maybe a comb? It states that it washes off easily with shampoo but even after a good scrub I still had some residue left behind. All in all I was disappointed by this product as it made it very obvious that I’d done a temporary root touch up!
