Gamechanger
I've really suffered with brittle hair for a long time but never really thought about the chlorine in our water in Cali. After seeing the Onsen&Oak ad, I decided to get one and it hasn't disappointed. My hair is so much better now.
Great pressure
Really love the pressure of the Halo. Our old showerhead that the landlord put in was very weak, but this is so much better. I'm a real shower person so good pressure is a must!
Worth It!
65 dollars is a bargain. I've been spending a small fortune on moisturiser and didn't even think that the problem was my shower, not me.
Must-Have
If you live in a hard-water area, this isn't a nice to have. It's a must have! The showerhead really has removed the chlorine from the water and I can feel it on my skin and hair. It's scary to think how much the water was working against me before!
Goodbye dry skin!
I've had the showerhead for one month now and it's really made a difference to my skin. We live in a hard water area and you can really feel the difference the filtration makes. So happy with it!
