Use apple cider vinegar as a rinse. It's acidic so it helps to remove the scaly buildup from your hair plus it balances the ph of the hair, smoothes down the cuticles, and leaves the hair feeling soft.
Lemon/Lime is also good since its acidic and helps remove buildup.
Attach a shower filter. It helps to reduce chlorine, and repels so many other harsh chemicals from hard water.
Use a nontoxic gentle clarifying shampoo to help clarify and remove the minerals. Some clarifying shampoos can be harsh on the hair so be mindful.
