Curly hair. You already know it’s different. It’s drier. It needs more moisture. It’s more fragile. And if you have hard water, it’s even worse.
We tested 6 shower filters on curly hair for 3 months. This is what actually happened.
The short answer: Curly hair is drier and more fragile than straight hair. Chlorine and hard minerals make it worse — drier, frizzier, less defined. A shower filter reduces that damage, which means softer, more defined curls.
Why Curly Hair Is Different
Curly Hair Is Naturally Drier
Curly hair has a harder time distributing natural oils down the hair shaft. That means:
– It’s naturally drier
– It needs more moisture
– It’s more prone to breakage
– It’s more sensitive to damage
That’s why your curly hair needs more care than straight hair.
Hard Water Makes It Worse
If you have hard water (85% of US homes do), your water has extra calcium and magnesium. These minerals:
– Build up on your curly hair
– Make it feel stiff and straw-like
– Weigh down your curls
– Make them less defined
– Make your products work less effectively
That’s why no amount of curl cream seems to fix it — the minerals are building up underneath.
Chlorine Makes It Even Worse
Chlorine also:
– Strips your hair’s natural oils
– Damages the cuticle
– Makes your hair frizzier
– Makes your curls less bouncy
The combination of hard minerals + chlorine = curly hair that’s dry, frizzy, and undefined.
How We Tested
We recruited 12 people with curly hair and had them use each shower filter for 3 months.
What we tracked:
– Curl definition (self-reported)
– Hair softness
– Frizz level
– How well their products worked
We also measured:
– Chlorine reduction (test strips)
– Flow rate
– Cartridge life
The 5 Best Shower Filters for Curly Hair
1. Zooshen Shower Filter — Best Overall
Price: $49.99
Media: KDF-55 + activated carbon
Certification: NSF/ANSI 177
Cartridge life: 4-6 months (1 person), 2-3 months (family of 4)
Annual cost: ~$60 (1 person), ~$100 (family of 4)
What we found after 3 months:
Zooshen uses KDF-55 media, which removes chlorine through a redox reaction. The activated carbon adds extra filtration for odors and VOCs.
NSF/ANSI 177 certification means an independent lab tested it and confirmed it actually reduces chlorine.
In our test, people with curly hair noticed:
– Softer, more defined curls
– Less frizz
– Their products worked better
– Hair felt less straw-like
Why it’s our top pick:
– NSF certified — you know it actually works
– KDF-55 + carbon — proven media combination
– Good flow rate — no weak shower
– Reasonable price — not cheap junk, not overpriced
– Low annual cartridge cost
The downsides:
– Doesn’t remove chloramine (need vitamin C for that)
– Doesn’t replace curl products — just makes them work better
Who this is for: People with curly hair who want softer, more defined curls.
2. AquaBliss HD — Best Budget Pick
Price: $34.99
Media: Multi-stage (KDF + calcium sulfite)
Certification: No full NSF
Cartridge life: 2-3 months
Annual cost: ~$80 (1 person), ~$160 (family of 4)
What we found after 3 months:
AquaBliss is the budget option. It works — chlorine reduction was solid in our tests. People with curly hair noticed softer curls after a few weeks.
But there’s a catch: cartridges wear out faster. In a family of 4, you’re replacing them every 1-1.5 months. The annual cost adds up.
Why it’s worth considering:
– Cheap upfront — good if you want to try a shower filter
– Multi-stage design — works
– Popular — lots of good reviews
The downsides:
– No NSF certification
– Cartridges wear out faster
– Flow rate drops more over time
Who this is for: People on a tight budget who want to try a shower filter for curly hair.
3. Sprite Showers — Established Brand
Price: $54.99
Media: KDF-55 + calcium sulfite
Certification: Partial NSF
Cartridge life: 3 months
Annual cost: ~$100 (1 person), ~$180 (family of 4)
What we found after 3 months:
Sprite has been around forever. Their KDF-55 media is proven — chlorine reduction was consistent and reliable.
But they’re more expensive, and cartridges cost more. And they don’t have full NSF/ANSI 177 certification.
Why it’s worth considering:
– Established brand — been around a long time
– KDF-55 media — proven performance
– Good reputation
The downsides:
– More expensive
– Cartridges cost more
– No full NSF certification
– Design is basic
Who this is for: People who want an established brand and don’t mind paying a bit more.
4. Jolie Filtered Shower Head — Best Design
Price: $99.99
Media: Vitamin C + charcoal
Certification: No full NSF
Cartridge life: 2-3 months
Annual cost: ~$200 (1 person), ~$400 (family of 4)
What we found after 3 months:
Jolie is the pretty one. It looks like a designer product. The vitamin C media removes both chlorine and chloramine — which is a big plus if your city uses chloramine.
But it’s expensive. Really expensive. Upfront, and especially in cartridges.
Why it’s worth considering:
– Beautiful design — it actually looks good in your bathroom
– Vitamin C media — removes both chlorine and chloramine
– Premium feel — nice product overall
The downsides:
– Very expensive
– Cartridges are very expensive
– No NSF certification
– Doesn’t last as long as KDF
Who this is for: People who care about bathroom aesthetics, or people with chloramine in their water.
5. Filterbaby — Best for Curly Hair
Price: $69.99
Media: Vitamin C + activated carbon
Certification: No full NSF
Cartridge life: 2-3 months
Annual cost: ~$180 (1 person), ~$360 (family of 4)
What we found after 3 months:
Filterbaby is the hair-focused option. It’s super popular in the curly hair community, and for good reason — the vitamin C + carbon combo is gentle on curly hair and removes both chlorine and chloramine.
But it’s not cheap, and cartridges cost a lot.
Why it’s worth considering:
– Hair-focused design — loved by the curly hair community
– Vitamin C + carbon combo — gentle on curly hair
– Removes both chlorine and chloramine
– Good for damaged curly hair
The downsides:
– Expensive
– Cartridges cost a lot
– No NSF certification
– Shorter cartridge life
Who this is for: People with curly hair who also have chloramine in their water.

Pro Tips for Curly Hair
-
Use lukewarm water, not hot. Hot water dries out your curls more.
-
Don’t over-wash your hair. Every time you wash, you’re exposing your hair to water. Less washing = less damage.
-
Use a deep conditioner regularly. Curly hair is dry. Deep condition to keep it healthy.
-
Use a microfiber towel. It’s gentler on your curls than a regular towel.
Frequently Asked Questions
Do shower filters actually help with curly hair?
Yes. Less chlorine = less dryness. Less hard minerals = less buildup. The result? Softer, more defined curls. Most people notice a difference within 2-4 weeks.
How long until I see results?
2-4 weeks of consistent use. It takes time for your hair to recover from the damage.
Should I still use my curl products?
Yes. A shower filter helps, but it doesn’t replace your curl products. They work together.
What if it doesn’t work?
Try a different media. If you have chloramine, you need vitamin C. If you have free chlorine, KDF-55 works fine.
