Editor’s tip: If you’re all about that rich, foamy lather, reach for a bit more product than usual to get the bubbles going.

Best Rinse: R+Co Teacup Anti-Pollution Detox Rinse
Why we love it: The R+Co Teacup Peacholine + Kombucha Detox Rinse, while not technically a shampoo, is a lightweight post-shampoo treatment that excels at detoxifying hair. It targets harsh metals like calcium, magnesium, and lead, along with everyday pollutants. Infused with peach leaf extract, fermented kombucha, and sunflower extract, it’s an excellent choice for tackling debris and hard water buildup. “Its sulfate-free formula is gentle and ideal for maintaining healthy hair, while citric acid effectively breaks down stubborn residues for a truly refreshed feel,” says Dr. Chacon. Unlike traditional shampoos, it doesn’t lather, and its precision nozzle is designed to deliver the product directly to the scalp, clearing buildup at the root.
Editor’s tip: Kombucha acts like a magnet to draw out calcium, iron, and other mineral deposits from your hair to deliver shine, strengthening, and smoothing benefits.

Best Budget: Ion Hard Water Shampoo
Why we love it: If you take a look at your showerhead and notice some calcium buildup, hard water buildup is likely the culprit. A go-to recommendation from Dr. Brimhall, Ion Hard Water Shampoo is a gentle yet powerful chelating shampoo that tackles this issue head-on. “Formulated with citric acid, malic acid, and panthenol—a.k.a. pro-vitamin B5—it cleanses and conditions hair at the same time,” she explains. Its soft lather removes hard water buildup without stripping moisture, making it perfect for color-treated hair. By clarifying, smoothing, and hydrating, it’s the perfect reset against hard water.
Editor’s tip: Malic acid, like citric acid, helps chelate hard water minerals to make them easier to rinse away.
Key ingredients: citric acid, panthenol, malic acid | Fragrance-free: no | Who it’s for: people with dry, damaged hair | Color-safe: yes
