Hi there Tanya,
It ultimatley depends on which conditioner you are using, and how often you are using it.
Conditioners should be used on the lengths and ends with every wash, but it may be that you are shampooing too regularly or not using the correct range for your hair.
I would suggest coming into a Carlton Hair salon for a consultation, and would also suggest that you try a Naturaltech nourishing treatment to restore moisture in your hair! Works like a charm everytime for the best results.
