A 50 ml bottle came with the starter pack. I tried it on my daughter Elle. She loves the smell of the watermelon scent so much that she asks me to smell it each time she bathes. I also like the aroma very much that I sometimes want to use it on myself. We didn't try the banana scent anymore. We bought the biggest size, which is the 500 ml bottle after the small one was used up.
This shampoo and body wash lathers up easily and rinses off just as well. It maintains the natural shine of Elle's hair. I also noticed that her skin doesn't dry like before when she used a commercial brand of body wash. I think this made her look forward to taking a bath more. :-)
