Because my hair is so fried from years of straightening, I took the plunge and got the Kerastase Bain Satin 1 shampoo & the Lait Vital conditioner. Very expensive but results are amazing. For the 34 fl oz shampoo, it was $98 if I remember it correctly. The conditioner came in a smaller 6.8 fl oz tube and was priced at $48 or so. I got them 20% off at Planet Beauty.
BAIN SATIN 1 Shampoo
Texture :

Pearly white in color and smooth texture and lathers into a light foam, not too thick not too light.
Price :

Very expensive.
Scent :

Fairly light.
Performance :

Leaves the hair clean, shiny and more manageable.
I have an oily scalp but dry and damaged hair so this shampoo works great for me. If you have dry scalp and damaged hair, I assume you need to use Bain Satin 2 or 3 shampoo.
I give it 5 stars.
LAIT VITAL Conditioner
Texture:

Thicker than the shampoo but goes on very, very light. Cannot feel much in your hair but it works for me since I have an oily scalp.
Price :

Very expensive
Scent :

Stronger than the shampoo but it is ok.
Performance :

Works great for my oily scalp. Keeps my hair manageable and easy to straighten. Less frizz and tangle.
I give it 4.5 stars only because it is very, very light.
