Yes you can use blue shampoo but just make sure you watch it the whole time because leaving the shampoo on for too long could result in the colour changing too much and the hair could turn too blue / purple / grey depending on the brand you use. Hair extension strands are more porous than your natural locks, so they absorb colours and toners faster and more easily.
Some cheaper shampoos can stain the halo more than others, we only recommend the blue shampoo by Evo and can't be responsible for misuse of blue shampoos so be careful :)
Here's a video demonstrating how to properly apply blue shampoo on your Sitting Pretty Halo: https://www.youtube.com/watch?v=YMXd5qP1mts
