Every filter has a finish line.
A fresh cartridge every 90 days keeps your water, and your curls, exactly where you want them.
Made for 90 days.
One cartridge, 3 months of daily showers. Built around how curl-girls actually wash: wash days, second-day refreshes, everything in between.
You won't feel the drop-off.
Once a cartridge is spent, chlorine and heavy metals slip straight through. The water still feels the same, but your curls notice within a wash or two.
Keep your results.
A fresh cartridge is the simplest way to keep the wash days you fell in love with: definition, softness, products that actually absorb.

Questions about your refill.
Every 90 days. That's roughly twelve weeks of daily showers, built around how you actually wash, not lab estimates.
You won't feel it in the water. It still runs clear. But your curls will notice within a wash or two. The Curl Reset Plan ships your next one on time so you don't have to guess.
Yes. One cartridge fits both the Handheld and the Rainshower. Same filter, same protection, same 90-day cycle.
Chlorine and heavy metals start passing through again. Your water will feel the same, but your curls won't. That's why the Curl Reset Plan ships before day 90.
Anytime. Manage from your account in two taps. No phone calls, no hoops.
Twist open, drop the old one out, drop the new one in, twist closed. 60 seconds, no tools. Turn the water on for 30 seconds to flush. Done.
