My hair tends to frizz, but because I don't use shampoo with SLS I'm trying not to use products with silicone/dimethicone etc. I keep seeing argan oil recommended and serum, but Frizzease etc contain silicone, and all the argan oils available on the high street seem to have dimethicone and similar in them. Can anyone recommend one without, preferably not one that will break the bank?
