I saw the ads for Aussie Dual Personality Root Cleanser and Tip Mender Shampoo and Conditioner and bought it to try. I've been really impressed. Supposedly there is silicone in the products that zaps up oil on roots and is mosturizing on ends.
I've used it a couple of times and it's worked great. I have long, thick hair that gets oily at the roots on about day 3 after washing (I wash every 3-4 days) and dry and brittle on the ends. My hair is really soft, manageable, and looks great. I also like that both products smell really nice.
I don't know if this will become my #1 shampoo and conditioner, but it's so cheap it's worth trying.
FYI: for drugstore hair products, Aussie does make some nice things. I also like the Knot Forgotten- it's a super light conditioner that is an excellent detangler and the 3 Minute Miracle for deep conditioning.
