Head & Shoulders, do you have a scalp problem? Are you diagnosed with seborrhoeic dermatitis (greasy dandruff, due to a yeast)? You might switch to Regenepure if so (sulphate free, contains the anti fungal ketoconazole).

Curly Girl method has you using a leave in conditioner every wash, do you not do that?
The Gliss Kur conditioner I sometimes use as a leave in conditioner and get a lovely curl boost. Or you could also use it as a treatment because it is quite rich in protein, one of the other regulars has done that. Just start with the damaged ends, if that works well for you then you can try higher up the hair. How often is a case of experimenting to see what your hair likes, start with once a week perhaps. You can use heat if you wish, these should help
