I went through 2 big chops until I was able to find a good routine and products that worked for my hair so I know how you feel. The first year, I was suffocating and clogging my curls with too much product. Then I tried to find a curly hair stylist that could give me tips and help me find the right direction. The first stylist I tried just destroyed my curls with blow drying and straightening with a hot comb then flat iron. I completely lost my curl pattern and just went back to straightening (without perm). My hair was still crazy until I realized that I have to work with my hair rather than trying to conform it a style that is just not working for it.
I started out with the curly girl method book in December 2011 and I have been modifying the technique ever since. I just needed that direction to start with. The Devacurl products are amazing but my pocket was taking a direct hit from that. So I have been No Shampooing and using a No-Silicone based conditioner (Tresemme Naturals).
Right now, my hair is manageable, but I still have a long ways to go. I cannot tell you how many times I had to go back to basics with my hair since this.
Now, I am all about keeping it simple so I just use Alberto VO5 Moisture Milks (as a Co-Wash), Tresemme Naturals (deep condition and leave-in), and Eco-Styler. I only do this once a week, but you have to research and try products that give you great results for your hair. I do not shampoo because from what I read, it is not good for curly hair, but if you can find a no poo with no sulfates, that's fine, but I think conditioner works just fine.
I also do not use combs or brushes. I have tried both the finger and comb methods and I prefer the finger detangle best.
I suggest check out Mahogany Curls and Naptural85 as a good starting point. Naptural85 has very good styling tips and Mahogany Curls has the simplest routine.
