GDPR and client records for salons: what you actually need to do

You keep names, phone numbers, allergies and treatment notes. That is personal data, some of it health data, and UK GDPR applies to a one-chair salon as much as to a chain. The good news: for a salon, doing it properly is mostly about keeping tidy records in one place. This is general guidance, not legal advice.

What you are allowed to keep

Anything you need to deliver the service safely and run the business: contact details, appointment history, patch-test dates, allergies, colour formulas, consent to treatments. Health-related notes need a clear reason (client safety) and should be kept only as long as they are useful.

Tell clients what you keep and why

A short privacy notice on your booking page does this: what you collect, why, how long you keep it, and how to ask for a copy or deletion. Plain language is fine.

Consent and patch tests

Consent forms and patch-test records should be dated and linked to the client. A digital intake form that the client completes before the appointment does this automatically and is easier to find than a folder of paper.

How long to keep records

There is no single number in the law. A common approach for salons is to keep treatment records for as long as the client is active plus a few years for insurance purposes, then delete. Write your rule down and apply it.

Marketing messages

Reminders about a booked appointment are fine. Promotional texts and emails need the client's agreement, and every message needs an easy way to opt out.

Security basics

  • Password-protected software rather than a shared notebook or a phone contacts list.
  • Staff see only what they need.
  • Backups you do not have to think about.
  • Export and delete a client's data on request.

Do I need to register with the ICO?

Most UK businesses that process personal data pay a small annual data protection fee to the ICO. Check the ICO's self-assessment tool for your situation.

Frequently asked questions

Can I store colour formulas and allergy notes?

Yes, with a clear reason (safe delivery of the service) and only as long as needed. Keep them in the client record, not in messages.

What if a client asks me to delete their data?

Delete or anonymise what you do not need to keep. You may keep the minimum needed for legal or insurance reasons; tell the client what you kept and why.
