I've been using both of these products for the past few months-
John Frieda Frizz - Ease Emergency Treatment Leave in Conditioner Spray and the Hair Serum Original Formula For Dry, Frizz‑Prone Hair

They are excellent products for keeping hair soft,I've found them to be better that the so called specialist conditioners .You can pick up these products in your local pharmacy or supermarket,I get mine at my local Tesco here in Dublin
