I bought this product as I wanted to have a go myself, rather than keep going to a salon. I was unsure if I could do it myself so I didn't want to spend lots of money in case I could not do it. I discovered that it is possible to do yourself with the powder at home. However, the colours sent were wishy washy and not strong or nice (I tried all 3 on the same hand). It took forever to get the product off even with salon strength acetone using foil and cotton wool soaking for 15 + minutes! Plus I felt like I had cement on my fingers. I left it on overnight before removing. Glad I tried it, but save your money.
