An item that makes dry, frizzy hair silky smooth

I'm sure you all have those moments when doing a hair treatment feels like a hassle, right?! I used to find it inconvenient every time too, so I couldn't do it often, but thanks to a friend's recommendation, I've been using a no-wash treatment since last year! After washing my hair, I just spray it on wet hair and dry it with a hairdryer, and that's it! My hair becomes silky and shiny, and it smells great, so I use it every single day!
