Definitely Aveda. My favorite is their Deep Penetrating Hair Revitalizer-

I've also been using their Cherry/Almond Bark Conditioner, which smells so good, like cherry soda-

i'll second the cherry/ almond bark,
but also mention for the bajillionth time that redkin's allsoft heavy cream is TO DIE FOR.
it literally transformed my dry and frizzy hair in one use.
i love love love it.
more than the aveda.
but the aveda is good too.
This. Is. The. Ish. The best $30 I've ever spent.
