I haven't used Swishy Coat but have used some other PP products - one being their Blow Dry Cream. I will never be without it again! Put a tiny bit on after a bath and there are almost no tangles and it makes the coat nice.
I have also tried the Volumizing Cream and that works pretty well for my little one with thinner hair.
I tried the Top Knot gel and didn't really like it much. I will try it again some time cause I don't want to waste it.
