Don’t let hard water ruin your skin & hair.
Your shower water hides silent aggressors. Over time, hard-water minerals, chlorine and salt build up and sabotage your skin and hair. Here’s what really happens:
Strip away natural oils from hair & skin :
- Dryness, Tightness, Itchiness, Sensitivity—and even Oily Rebound.
Dissolve hair lipids causing :
- Dullness, Frizz, Dandruff andSplit Ends.
Damage amino acids/keratin :
- Weaker Strands, Shedding and Hair Loss.
React with natural melanin & dyes :
- Color Fade, Brassiness and Loss of Shine.
Irritate the skin barrier :
- Acne, Rashes, Eczema and Psoriasis flare-ups.
With every unfiltered shower, your skin and hair pay the price. Jolie protects you at the source.

DRY SKIN GIRLIES UNITE
Love love love my skin freaks out without it as an Afro Latina my parents would be like this is so millennial and a luxe want but it is super important you need this and it makes a difference my hair and my skin thank me!

CLEAR-SKIN TURNAROUND
I moved to Dubai and my face and back started breaking out like crazy. I kept swapping products with no luck. Two weeks after installing the Jolie Shower Filter, the constant congestion calmed down, fewer new spots, and my skin feels clean—not tight or itchy—even after long, hot showers. I didn’t change my routine; the water did.

EXCEEDS EXPECTATIONS
I always felt itchiness and feeling I didn't bathe or shower enough because I didn't feel clean. Needless to say it wasn't me or my feelings that was the problem, it was my shower head. Transitioning to Jolie was a game changer; after my showers I no longer felt the itchiness I previously felt and my skin was left feeling clean and rejuvenated as well as my hair feeling soft.

MOM HERE
We love her. The shower head fixed my postpartum shedding. It didn't work as quickly as the other comments. It took me a month to see a difference, 2 months for hair to be back. If you are reading this and skeptical...I was shedding all through pregnancy and right after giving birth it got even more noticeable. I got haircuts and nothing helped. I KNOW this showerhead was it. Jolie - Mom's should be your next customer focus! As for the skin aspect, I do think it did impact it as well. It basically can be considered like the "whip cream on top" if you already have a regimen.

BYE-BYE BRASSINESS
Between the sun, pool days, and our tap water, my balayage used to turn brassy in 10 days. With Jolie, my tone stays fresh, shine is back, and I’m stretching salon visits from 4 to 7–8 weeks. Water pressure still feels “spa,” and my purple shampoo finally works again.
