4 photos guided by an outline: front, both temples, top. They take themselves once everything is sharp and well framed.

The light changes, the angle changes, and so does your memory. RLYNE always takes your photos the same way and measures them, so you see the real trend, with its margin of error. Not a feeling.
4 photos guided by an outline: front, both temples, top. They take themselves once everything is sharp and well framed.

A report every week, one every month, and a big report at 3, 6, 9 and 12 months: your first day compared to today, zone by zone.

A program made for your stage and your approach. Every night, you check off what you did. RLYNE tells you when to adjust.

The app checks distance, angle, lighting, and that your hair is pulled back flat. A photo not sharp enough? It tells you, and you only retake that one.






A change smaller than the margin means stable. RLYNE never declares victory too early, and never panics you for nothing.
You choose how far you want to go. RLYNE suggests the methods backed by evidence, explains how to do them, and adjusts based on your reports.

Each method has its step-by-step guide, its level of evidence and its sources. For a non-prescription product, the amount on the label. For a prescription drug, never a dose: that's for you and your doctor to decide.

No. RLYNE measures and tracks how your hair changes; it doesn't make a diagnosis. It helps you prepare for an appointment with a PDF report of your measurements.
Nowhere. They stay on your iPhone, and the analysis happens there. Only the numbers (measurements, margins, stage) are saved for your reports, with your consent.
Hair grows about 1 cm a month. Scanning more often would only show noise. Once a week, same day, same light: that's what makes the reports reliable.
