Which Wen hair care collection by Chaz Dean should I choose?

Hi. Im an African American young woman and I have read the reviews. I would like to try it but it seems the different collections (Lavender,Fig and Sweet Almond Mint) can take care of different hair problems for different hair types. So far I have to choose between Sweet Almond Mint and Fig. Other black women have mostly chose Fig. I have long hair, dry scalp,Dandriff,and knots. What is each one like(Sweet Almond Mint, Lavender, and Fig) and what hair problems does each one take care of ? Please list.Which one should I buy?
