The problem REHASH solves

Every treatment has
a dormant patient list

Click a treatment to see how inactive patients in that category are typically lost — and how REHASH brings them back.

The typical scenario

A patient misses their annual check-up. Nobody notices.

Most practices rely on the patient to rebook. They don't. Life gets busy, the appointment slips by, and 12 months becomes 18 months — then two years.

Month 0 — Last check-up attended
Month 12 — Due for check-up. No contact from clinic.
Month 18 — Patient books elsewhere or simply doesn't go.
REHASH sends Email 1 — Personalised to their last visit, written in your voice, referencing your clinic.
The typical scenario

Hygiene patients need 6-monthly reminders. Most get nothing.

Hygiene is high-frequency, high-value — and highly forgettable. Patients intend to rebook. They don't. That's two missed appointments a year per patient.

Month 0 — Hygiene appointment completed
Month 6 — Due again. Relies on patient memory.
Month 9 — Still hasn't rebooked. Gum health deteriorating.
REHASH sends Email 1 — Referencing their last hygiene visit, gentle urgency, easy reply CTA.
The typical scenario

A patient enquired about whitening 8 months ago. Never came back.

Cosmetic patients are highly motivated — but motivation fades without a nudge. Many enquire, go home to think, and never rebook because no one followed up.

Month 0 — Enquired about whitening at their last appointment
Month 3 — Still thinking about it. No follow-up from clinic.
Month 8 — Booked whitening at a competitor.
REHASH sends Email 1 — Referencing their interest, low-pressure, warm tone.
The typical scenario

A patient had a consultation for Invisalign. Never committed.

Ortho consultations are a big decision. Patients need time — but most clinics give them space rather than a gentle nudge. A well-timed email changes the outcome.

Month 0 — Free Invisalign consultation completed
Month 1 — Sent a quote. Patient went quiet.
Month 4 — No reply. Assumed they went elsewhere.
REHASH sends Email 1 — Low pressure re-engagement, answers common objections.
The typical scenario

An aesthetic patient is overdue for their follow-up treatment.

Botox and filler patients typically return every 3–6 months. Without a reminder, many drift — booking at a cheaper competitor or simply letting results lapse.

Month 0 — Botox treatment completed, results excellent
Month 3–4 — Results fading. No contact from clinic.
Month 5 — Booked at a walk-in aesthetic clinic nearby.
REHASH sends Email 1 — Timely, personal, references their last treatment.

What is REHASH

Turn a dormant patient list into booked appointments

Most clinics have hundreds of patients who haven't visited in over a year. They haven't left — they've just been forgotten.

REHASH reads your clinic website, understands your treatments and tone, then builds a personalised 3-email reactivation campaign — sent directly from your own Gmail, to your own patients.

No agency. No monthly fee. No technical skill required.

AI reads your clinic automatically Paste your URL. REHASH extracts your treatments, tone, and USPs — no manual input needed.
Emails that sound like you Each email is personalised per patient and written in your clinic's own voice — not a generic template.
Sent from your own Gmail Emails arrive from your clinic address — better deliverability, more trust, no bulk-sender red flags.

Why we built this

Your existing patients are your biggest untapped asset

Most dental and aesthetic clinics pour budget into acquiring new patients. Meanwhile, hundreds of patients who already trust them haven't returned in over a year — not because they left, but because nobody followed up.

Reactivating an existing patient costs a fraction of acquiring a new one. They know your team. They've already paid you before. They just need a well-timed, personal message that reminds them you're there.

We built REHASH because no tool existed that was simple enough for a practice manager to use in ten minutes, yet smart enough to send emails that genuinely feel like they came from the dentist themselves.
