What do you mean that you have to resoften the water every few days?
I've considered getting a water softener, but I wasn't sure if it would be worth it since the water here isn't too hard. Do you mind telling me what benefits you noticed?
I don't remember the exact name of what it's called. But you have to regenerate/recharge the materials in the chamber by filling it with salt water and then running the water. I think you also have to do this with a full home water softener but because the water stick is much smaller you have to do it more frequently. I would literally have to do it every 3-4 days to keep the water soft. When I got tired of doing it that frequently I would just do it on wash days to use the soft water on my hair.
As for benefits, the water definitely FEELS better on skin/hair. It's got this weird slippery feeling and you don't need to use as much soap
Or products. I can't quite remember how my hair benefited. This was at the very beginning of my HHJ when I was doing the most all at once and didn't really know how to listen to my hair.
