Silicone free leave-in conditioner or serum

[TeaAddict235]

Can anyone recommend an easy to find (high street) either leave in or hair serum/smoothing cream please? I would ideally like to be able to smell it first, so ordering off the internet isn't an option.

Trying to loosely follow the curly girl method, but so many YouTube vloggers order from the US at extortionate prices, and I'd prefer not to have to do that.

All suggestions welcomed. Thank you.

Aussie stuff works on my hair, through much trial and error.

Doesn't make it feel coated as some brands do.

I don't think Aussie is silicone free- boots naked is and has a leave in conditioner but I don't like it ! Haven't found a silicone free serum or oil anywhere (except plain coconut oil which is a good conditioning treatment but too heavy for me as a styling product.
