My salon has started using Kevin Murphy products and my stylist used the Heated Defence spray and it gave me amazingly soft volume. I have very fine hair and little of it so this product really worked. There are various volume products out there that work but this one kept my hair soft which is uncommon. The price and the smell (heavy, musky perfume) will keep me from buying it often. They also use the shampoos/rinses at the salon and while they also seem to be great, they are an expense I am not willing to pay.
