I have straight fine hair that has a top layer of frizz that is determined by the weather. I've tried a gazillion products, treatments, serums and home made hair concoctions. I could have probably gone on an overseas holiday on what I have spent trying to fight the frizz. My hairdresser introduced me to Joico and I must say this product is the bomb! I only apply once a week, it takes 10 minutes to do it's thing and I am left with silky, soft hair like I stepped out of a salon. It's not cheap at R285, but really worth it and you only need a little at a time.
