ALTHY Vitamin C Revitalizing Shower Head Water Filter - Reduces Chlorine, Heavy Metal & Softens Hard Water- Prevent Dry Itchy Skin, Hair Loss, Dandruff (Includes 4 Filters)

I bought this filter after a friend's recommendation, and I couldn't believe how much better it was for my hair immediately. Replacing the old showerhead for $50 was the other change I made later, and now there is zero mineral buildup on the shower screen anymore. The difference is stark.
