The Kurette Shower Filter has a sleek design and is very easy to apply. For best results lower the water pressure to allow the filtration process to absorb as many chemicals and impurities as possible.
I really like this shampoo — it does exactly what it claims and noticeably reduces frizz. The only downside for me is that I have thin hair, and I’ve found imy hair gets greasy faster compared to when I use other shampoos. Because of that, I need to wash my hair every day or every second day. Aside from that, I’m very happy with it.
