Aussie shampoo and deep conditioning treatment- curly hair

[BananaChew]

Bought these last week in the hope of reducing ingredients the dryness in my hair. I used to use cheap argon oil stuff, and was able to leave it 4-5 days between washes. This stuff leaves my hair feeling less clean and more greasy, and have to wash it every 2/3 days. Would you persevere? Should I not use the deep conditioning treatment after each wash? Help!
