Try using hair oil in the summer.

This is an item my husband likes more than I do. It is Anove Hair Oil. He said he dislikes hair gel because it is sticky and wax because it makes his hair too stiff, but he ended up buying this because he liked it. I don't really like putting products on my hair, so I didn't use it, but I've been using it this summer to tame the frizzy curls that come up. It is not completely free of stickiness, but the scent is nice, so I am using it well.
