Hair color fades in the shower mostly because water and shampoo wash dye out of the hair, and hot water speeds that up. Chlorine in tap water is an oxidizer that can add to the fading over repeated washes.
- Colorists advise cooler water, a sulfate-free shampoo and fewer washes.
- US tap water may carry chlorine or chloramine at up to 4 mg/L, the EPA's maximum residual disinfectant level.
Our pick: if you want the chlorine out of the water you rinse your color in, the Second Showerhead ($99, or $79 with a filter subscription): its Vitamin C core reduced free chlorine and chloramine by 99.9% in independent lab testing, held through Day 1-60 in our own testing.

FAQ
Can shower water cause hair color to fade faster?
Yes. Chlorine is an oxidizer that strips color molecules from treated hair. Filtered showers can significantly extend the life of color treatments.
Does hard water cause hair loss?
Hard water doesn't directly cause hair loss, but mineral buildup can make hair brittle, dry, and prone to breakage — which can look and feel like thinning.
What type of shower filter is best for hair?
Vitamin C filters are ideal for hair: they neutralize chlorine without adding chemicals, and they don't reduce water pressure like some KDF filters can.
How does Second Shower help with hair health?
Second Shower's NSF-certified filter removes 99.9% (during the cartridge's peak performance window, Day 1–60) of chlorine while infusing Vitamin C, which helps maintain moisture and protect color-treated hair.
