Best products to improve hair condition?

Whenever I bleached my whole head I used a product line called infusium 23. They sell it at cvs/walgreens and its in a grey bottle. They have shampoo, conditioner and a leave in treatment. I just use the leave in treatment. And make sure you get the "repair" kind. Just after you shower squirt it in your hand and comb it through your hair to the ends and it works like magic. :)
