I have tried this cream colour in 14 and 15. It is quick and easy to use. It has no strong smell and very few chemicals. The main colouring agent is henna. The colour is great and my hair is strengthened and shiny after use. It applies easily right out of the tube (no mixing - YAY!) , shampoo on, wait 20-30 mins and rinse off. The colour lasts several weeks and it even covers grey's.
