Ladies beware!
Last night as I was washing/twisting my hair I noticed that my hair was becoming tangled like it did when I would wash with hard water. So, I pulled out my hard water test strip and tested the Walmart DW. The results came back as "hard" water
. I thought maybe it's just with this jug, but then I tested the other four gallon jugs I had and they all tested for "hard" water.
Now, when I first started using this brand, I did a test then and the water was soft water. Not sure what has happened, but I decided to go with Ozarka DW. I tested it and the water was "soft". It may cost more $1.06 compared to Walmart's $.58, but my hair is worth it. LOL!
I guess what I'm saying is to test your DW to make sure that it is not "hard" water, but in deed soft water you are using to care for you hair.
The walmart brand was still softer than the "very hard" water that comes from my faucet (tested this water as well), but never the less, it's still hard water.
Just f.y.i.
