I have very hard water where I live. I use this once or twice a week and it really helps remove the build up on my hair. I'll definitely keep using this.
positive

I got two bottles for my newborn with no issue. On the third bottle, discovered a dropper that wasn't built into the cap. Not sure if it's a defective batch or what. (Which means you'd have to wash the dropper every time... not ideal at all.) I submitted for a return/replacement and the fourth bottle I got had the same issue. If this is just a new design, I'll definitely have to just switch brands. :(
negative

Bag just bust a seam at bottom. Now it is useless. I had originally written a positive review, but apparently I spoke to soon. Edited it to reflect poor quality of product. Another edit: Seller never replied to my email. Money-back guarantee is a scam.
