i have very dry thin frizzy hair and i use a range called Keratase, its quite expensive but almost like a god send to me and the product out of all of there range is the creame heat control is" cemint thermique" and it actualy helps your hair when the heat is drying and styling your hair the condition of my har is gr8 now, and its also seems to stop iHair going frizzy in the heat and wet more than any other product i have ever used my hair looks and feels like silk If you cant afforrd the shapoo and conditioner, i would def recomend the thermique. I am in uk and you can only get it in hairdressera and a tube of this will last me about10 mths and cost around �15-�18 . as u only use a squirt not bigger than a 5p ... It has saved me chopping all my hair off...... But If you see a salon that actually sells it just pop in and ask if they have a free samples of the product or products and they will tell you what stregh to use as there are 3 different types....also they do a sun leave in conditioner which is brill for holidays as its not at all greasy and as with the thermique works in same princible ...when it heats up your hair becomes healhier good luck but if u in the states u prop just but it in a hair products shop at half the price as th, ey normally have loads
