Kiehl's Creative Wax
My hubby has used Kiehl's Creative Wax ever since I can remember. It keeps his thick wavy hair smooth and styled all day long. I have used it too when I do half up hairstyles to tame those flyaways. There was even a shortage last summer so when it was restocked he stocked up.
If you're looking for a good styling tool for texture or smoothing, this one is the magic potion.
