My hair texture is a lot like yours-it is fine and frizzy. I really like L'Oreal's "Out of Bed Weightless Texturizer" paired with a leave-in conditioner. It makes my hair clump nicely like a curl cream, and feels natural. I tried it on a whim and loved it, and have been using it for a little over a month now.

In general, I've found that creams work better than mousses for fine hair, and that diffusing until it is 50% dry sometimes helps to make it less frizzy and more curly. Hope this helps!

Also, I was born in Scotland, but am of Irish descent
