I have been using Schwartzkopf since 2013 and i always recommend it for a bright and healthy colour. As someone who usually dyes her hair often i know that after a while the colour tends to go dull. I must say that i even though my hair growth is now visible ( with colour ) the colour left on my hair is still full of life. i have very dry and brittle hair so the Deluxe Oil- care range is definitely something that my hair needs when dyeing.
