Matrix optic shampoo or loreal xtenso shampoo?

Loreal xtenso is also on the expensive side! It retails for some 800-850 for 200ml bottle
On the other hand matrix one costs around 300-350 for the same 200 ml bottle!

So you can consider this point while buying too!

The one that the salon people recommend is the loreal one coz it's a professional shampoo but I have heard that the Matrix one is better! People experience less hair fall using the matrix one than the loreal one!
