I have medium blonde hair, and I use the kair highlight kit every few months to add some colour. People always comment on how nice my hair colour looks! This highlight kit is very effective and lasts long, as I wash my hair everyday and it takes about 12 weeks before I need to redo the colour. It gives a professional look. I don't follow the recommended time on the box, as I keep it in for about 25 mins for that natural blonde look. It is however VERY drying on my hair, and wish that Kair would include a treatment or conditioner in the box for afterwards! I have to use a damage reconstruct conditioner because my ends get so dry!

Otherwise, for the quality and price I will keep using.
