Now that I have tested some heat protection sprays, I am the most satisfied of Wella. With conventional spray from the drugstore I've learned that they have an unpleasant smell, the spray head is much too large pores and thus the hair is too wet and sticking mainly! A beautiful styling with the flat iron or curling iron there was not really possible. From the heat protection spray Wella I was really excited. It smells pleasant, you can dose it easily and it also contains a strengthener of stage 2, so that the hair longer maintain their styling. The 150ml have kept with me about half a year. I am really more than happy with the price-performance ratio!
