Banana Shampoo and Conditioner by Garnier, is it worth it?

I have been hearing about banana based hair products for a while now and seeing them in pretty much every drugstore. Even had some clients asking me, wether those products are really worth the hype. So as a hairdresser I was intrigued. 

Now I do know that there are a lot of benefits to bananas. They are great for you to eat, add to beauty products and sure, must be great for hair too. After doing some reading I figured out a few things. Biggest benefit of bananas is, as most of us know, pottasium. They are also rich in natural oils, vitamins and carbohydrates. All that means a potential of a great moisturizer and softener. So does it really have the benefits it promises?
