I'm currently not following the curly girl method, but I think it''s time too.. Every time I use a new product my hair seems to do well with it. But after lets say two or three days of using the new product, my hair reacts really badly to it. It ends up getting dry and can be sticky due to the product. Nothing seems to be working for me right now. Does this/did this happen to any of you guys?

I have 3b with a bit of mix of 3c hair type. Thick..Hair tends to be coarse..
When I was little I use to have smaller coils, but I think after two weeks of straightening in middle school and probably using things like moose and gels overtime the pattern has loosen. I gotta say, I miss my original curls. Anyway to revive them?
