My hair is always frizzy too(unless I refuse to wash it far a week). One product I use that helps is smoothing shine milk by Biolage. It makes you’re hair feel silkier without the gunky feel and it’s not at all greasy. I don’t know how good it is for you hair for the long term as I’m no professional and I can’t be bothered to use products very often. One word of caution though, be careful spaying over smooth flooring. It can make more than just your hair smoother(and slipperier) too.
