I love the Pantene PRO-V Restoratives Breakage Defense Conditioner.  I noticed a great amount of improvement after just one use.  My hair seemed softer and really seemed to shine.  I regularly use Pantene products because I have found they are great for my flat, straight, thin, brittle hair, but this stuff is even better.  It really strengthens your hair and helps eliminate getting split ends.  My hair tends to break from just about anything.  I have tried many different types of shampoos and conditioners for flat hair, dry hair, brittle hair, oily hair, etc.  This has definitely worked...
