Silicone free deep conditioning treatment for frizzy hair?

[Destinysdaughter]

Anyone know of a good one? I've stopped using silicone which is fine but my hair feels a bit straw like at the moment ( going grey so is dyed blonde). My hair is wavy, slightly curly and fine. Any suggestions please? 😀

Coconut oil is brilliant!

Pure argan oil is great!

Jason shampoos and conditioners are lovely, I use the Sea Kelp one (often on offer on Ocado) and it leaves my hair in lovely condition.
