A shower filter will not stop hair loss caused by genetics, hormones, stress or illness; a dermatologist can find the cause. Losing some hairs in the shower is normal, and a filter changes only the water, not the follicle.
- Shedding 50 to 100 hairs a day is normal (American Academy of Dermatology).
- US tap water may carry chlorine or chloramine at up to 4 mg/L (US EPA).

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 Vitamin C filter delivered 99.9% chlorine and chloramine reduction in independent lab testing, held through Day 1-60 in our own testing (Day 1-30 for the Showerhand), with an NSF/ANSI 42 certified sediment pre-filter, while infusing Vitamin C.
