I agree with all the suggestions everyone has posted. Two other thoughts-
* with the colder weather, do you have a humidifier? The drier air will zap the moisture from your hair, so whatever progress you're making will be hard to see right now.
* have you ever tried sleeping with conditioner on your hair? I wash my hair in the evening and once I've put on the conditioner and cap, I leave it on until the morning. You will have at least 6 hours of conditioning and your hair won't be exposed to the air for that time.
