Review (4/5): Smoothes and adds shine
The brush makes my hair softer and shinier. But not a huge difference to be honest.
The massage function I didn't really care for. The vibration is pretty weak so I couldn't feel it even when I pressed the brush against my scalp. But I bought this mainly for the ion function so I don't mind.
The bristles are okay, just like any other brush. Doesn't do a great job of detangling and pulls out some hair. So I use my other detangling brush first then use this one for extra shine and smoothing.
It might also help with frizz, but I'm not very sure. Quality is good, packaging is good too.
