Welcome, avourene, and congratulations on your decision to "end the madness".
I stopped relaxing a year ago and have only had a few short trims. Although the two textures do frustrate me at times, I find that regular deep conditioning and moisturizing treatments have helped.
If you can afford it, you may want to try products with no sulfates and low (or no) silicones and stick to more natural ingredients like butters and oils. (Olive oil and avocado butters seem to work best in my mostly 3C hair.) You may have to experiment to see what works best for you.
I decided I wasn't going to spend money on expensive products until I get all the relaxer cut off (maybe in January/February 2009), but that's just me.
Let us know how things go with you.
Currently experimenting with:
Pre-shampoo treatment - Burt's Bees Avocado Butter
Shampoo - Max Green Alchemy (Organic)
Rinse-out Conditioner - Suave Naturals Coconut (I detangle in the shower while I have this in my hair)
Deep Treatment - Olive Oil Replenishing Pak
Leave-In Treatment - Alternating between Olive Oil Moisturizing Lotion and Sunsilk Anti-Esponja (these have some silicones)
Styling Gel - Bioterra Styling Gel
