Questions
Frequently asked questions
What is ZYEA?
ZYEA is an iPhone hair care app. It learns when to wash your hair based on your roots, guides you through wash day, reads your photos with AI and tracks your progress. For straight, wavy, curly or coily hair.
How often should you wash your hair?
There’s no single rule. Depending on your hair and scalp, it ranges from every day to once a week, sometimes less. ZYEA learns your rhythm from your roots and suggests the right day.
What’s a good wash day routine for curly hair?
Wash when your scalp needs it, and at least every 2 to 3 weeks. Apply conditioner through your lengths and detangle in the shower with a wide-tooth comb, starting at the ends. After that, the less you pull, rub and use heat on your curls, the better they’ll keep their shape.
Greasy roots the next day: is that normal?
Yes, it’s common, especially with fine, straight hair: sebum moves down it quickly. You can wash every day with a gentle touch. Washing doesn’t make your roots oilier, and waiting won’t train your skin. If this starts suddenly along with acne or irregular periods, talk to your doctor.
How does ZYEA find my wash day?
When your roots need a wash, tap “Needs a wash” on Today. After a few washes, ZYEA learns how many days your roots stay fresh and suggests your next wash day. You can always move it.
Is ZYEA free?
Yes, the essentials are free: your wash day, your guided wash, your reminders, the widget, one photo reading and one article every Monday. ZYEA Pro is an optional subscription. Its price is shown in the app before any purchase.
What does ZYEA Pro add?
Photo readings and comparisons—6 a week, including haircut ideas. One haircut try-on a week. All guides, daily moon guidance and online photo backup.
What happens to my photos?
Your photos stay on your phone. For a reading, your photo is sent to Gemini, Google’s AI. ZYEA’s service doesn’t keep the photo or the response, except for up to 10 minutes if a free reading is interrupted. Google keeps the request and response for 55 days to prevent abuse. With an account and ZYEA Pro, your photos are also backed up online.
How does the AI read my hair?
ZYEA shows your photo to Gemini, Google’s AI, then tells you what it sees in its own words: frizz, how defined your curls are, photo quality. It’s a guide, not a diagnosis. You can turn it off at any time in the app’s settings.
When does ZYEA remind me to wash?
The evening before or the morning of your planned wash day, as you choose in “Settings” > “My rhythm.” You can also turn reminders off.
Does the moon really work?
It’s a tradition, not a promise: no studies show that it changes hair growth. ZYEA shows the moon calendar with ZYEA Pro for anyone who enjoys following it, and makes that clear.
Do I need an account?
No. You can start without one: your tracking then stays on your phone. An Apple or Google account backs up your tracking online. It’s required for ZYEA Pro.
How old do I have to be to use ZYEA?
You must be 18 or older. Google’s AI service Gemini, which reads the photos, requires it. The welcome screen asks your age range, and your answer stays on your phone.
How do I delete my account?
In the app, open “Settings”, scroll to the very bottom and tap “Delete my account”. You confirm with Apple or Google. Deleting your account doesn’t cancel a subscription: you cancel it in your Apple account.
Does ZYEA work for curly and coily hair?
Yes. Straight, wavy, curly or coily: the welcome asks for your texture and your steps adapt to it. For coily hair, the quick wash takes three steps.
Is this medical advice?
No. ZYEA gives hair care tips, not a diagnosis. If your scalp often bothers you, talk to a doctor.
Is ZYEA on Android?
Not yet. ZYEA is coming to iPhone first.
When is ZYEA coming out, and in which languages?
Soon, on the App Store, for iPhone. The app speaks English, French, Spanish, Portuguese, German, Italian and Dutch.

Your next wash, right on time.
ZYEA is coming soon to iPhone. Write to us and we’ll let you know on launch day.
