Do you live in a particularly low or a high humidity area? I found that taking the dew points into consideration (and thus choosing my products based on appropriate ingredients) helped with my frizz a TON.

Also, deep conditioning with a bonnet dryer/heat (to help penetrate the hair shaft) was like magic for my hair.

HTH!

2c/3a, fine, low porosity.

Poo: Garnier Fructis Pure Clean (yes, it has A Sulfate!!, but I have Teflon hair)
Co-wash (when I feel so inclined, which isn't often!): VO5 Kiwi Lime Clarifying Conditioner
Conditioner/LI:
same for both -- whatever I have in the shower at the time (I experiment a lot)
Style: EcoStyler Olive Oil <3
Dry: Diffuse or air dry, or both...depends on my mood
