Hey!
For me to further help you out, I am going to need to know a little bit more about the products that you are currently using:
What Shampoo do you currently use? Does it contain sulfates in it?
What condioner do you currently use? Does it say that it is designed for dry hair?
Do you ever deep condition your hair with heat?
What styling and or/moisturizing products do you currently use?
How often do you wash you hair?
Do you let your hair airdry or do you blowdry it?
