Some beauty treatments under 16 may be possible, but parental permission is only one part of the decision. Before accepting a booking, check the exact treatment, the law where you work, your insurance terms and the product manufacturer’s instructions. A signed consent form cannot override an age restriction, and the young person must be comfortable with what is proposed.
For a new therapist, the practical question is not simply “Has their parent agreed?” It is “Can I safely and appropriately offer this particular service to this client, under all the rules that apply?” This guide separates those checks so you can make a clear decision before the appointment.
Guidance checked on 27 October 2026. Rules and policy terms can change; check the current requirements for your treatment and UK nation.
Beauty treatments under 16: what should you check first?
Use these four checks together:
- Law and local requirements. Some procedures have a statutory minimum age. Your council may also impose conditions through a treatment or premises licence. GOV.UK explains how to check special-treatment licensing with your local council; requirements are not identical everywhere.
- Your own insurance. Confirm that the named treatment is covered for the client’s actual age. Check consent, attendance, testing and record requirements in your policy and schedule, rather than relying on another salon’s practice.
- The product and equipment instructions. Read the age warnings and suitability restrictions for the exact system you use. Parental permission does not cancel a manufacturer’s warning.
- Individual suitability and willingness. Complete the relevant consultation, work within your training and decline if the treatment is unsuitable or the young person feels pressured.
You can adopt a stricter minimum age for your own business. Make it clear before taking bookings, including for birthday parties, school events and appointments arranged by a parent.
A treatment-by-treatment starting point
This is a checking guide, not blanket permission to carry out a service. On a small screen, swipe the table sideways to read both columns.
| Treatment | What to establish before booking an under-16 |
|---|---|
| Manicure, pedicure, makeup or a basic facial | Do not assume a simple service is automatically suitable. Check the precise products and procedure, consultation findings, insurer’s age terms and any local conditions. |
| Gel polish, builder gel or acrylic nails | Ask about the specific nail system and client’s age. Permission for a manicure does not establish cover or suitability for enhancements. Do not improvise an allergy test by applying uncured gel to skin. |
| Waxing or threading | Specify the area being treated. Do not treat ordinary hair-removal permissions as permission for intimate waxing. The Guild’s published insurance guidance excludes intimate waxing for under-16s even with parental consent. |
| Lash or brow tinting, lifts and extensions | Check each service and product separately. Some tint products state they are not intended for under-16s. Required sensitivity testing is an additional check, not a way around an age warning. |
| Spray tanning | Check product suitability, insurer conditions and the proposed service. Spray tanning and UV sunbeds are different treatments; do not transfer the rules for one to the other. |
| UV sunbeds | Commercial sunbed use is prohibited for under-18s across the UK. A parent’s consent does not make an under-16 booking acceptable. |
| Tattooing, microblading or semi-permanent makeup | Do not book an under-16 for cosmetic tattooing. In Great Britain, tattooing under-18s is prohibited, apart from a narrow medical exception. Check the separate rules and registration requirements for your nation and procedure. |
| Cosmetic botulinum toxin or injected fillers | In England, administering these to under-18s, or arranging the appointment, is prohibited under the 2021 Act, subject to its doctor-approved exceptions. Parental permission alone is not an exception. |
| Laser, IPL and other advanced procedures | Obtain procedure-specific advice on current law, registration, practitioner competence, device instructions and insurance. A policy for everyday salon services does not answer these questions. |
For the statutory restrictions, see UKHSA’s sunbed guidance, the Tattooing of Minors Act and England’s botulinum toxin and filler guidance. Hounslow Council’s special-treatment conditions explain that micropigmentation is a form of tattooing; its additional local conditions should not be presented as UK-wide rules.
Does a parent or guardian have to stay?
Check your own policy before saying yes or no. Published insurance conditions differ. Insync’s beauty insurance FAQ says a parent must remain throughout an under-18’s treatment and sign consent beforehand. The Guild’s insurance FAQ describes a different arrangement for clients aged 16 or younger, allowing prior written permission for a parent or guardian not to attend, subject to its conditions.
These are examples of policy differences, not recommendations of cover or confirmation that your qualification or appointment is insured. Ask your insurer in writing:
“I hold [qualification] and want to offer [exact treatment and product system] to a client aged [age], at [salon, home or mobile location]. Does my policy cover this? What consent, parent or guardian attendance, testing and record requirements apply?”
Keep the reply with your policy records. If the answer is unclear, resolve it before confirming the appointment. Our qualifications and insurance information explains NSB’s training position; recognition of a qualification is separate from cover for a particular young client.
Make the consultation about the young person too
A parent booking the appointment does not tell you whether the child wants it. Explain the proposed service directly to the young person in language they understand: what will happen, what it may feel like, relevant risks, alternatives and aftercare. Give them time to ask questions and make clear that they can ask you to stop.
As a practical appointment checklist:
- Confirm the client’s age and who is giving any required parental or guardian consent. Check unclear details before proceeding.
- Describe the exact service on the consent record; avoid a vague approval for “all beauty treatments”.
- Complete the consultation and any checks required by your training, insurer and manufacturer. Do not diagnose a skin or nail condition.
- Confirm the agreed attendance arrangements, privacy and aftercare before starting.
- Stop if the young person withdraws agreement or becomes uncomfortable. Do not let pressure to finish the appointment decide what happens next.
Record the consultation, consent, required tests, products used and aftercare accurately. Store records securely and confirm retention requirements with your insurer, including any different period for children’s records.
Age warnings and patch tests are separate checks
For example, the published safety information for Salon System Lash & Brow Tint states that it is not intended for people under 16. A parent’s signature or a sensitivity test does not remove that warning.
Follow the current instructions for the exact product and the relevant insurance conditions. Do not assume every lash, brow or nail product uses the same testing method or timing. The British Association of Dermatologists warns about allergy from uncured nail products touching skin. Medical allergy patch testing is a specialist dermatology procedure, not a salon experiment with uncured gel.
FAQs about treating under-16s
Can a 14-year-old have gel or acrylic nails?
There is no useful universal “yes” for every system and policy. Check the client’s age against the manufacturer’s instructions, your cover, local requirements and the consultation. A parent agreeing does not settle those checks. If any required condition cannot be met, decline the service.
Can a signed disclaimer replace the required checks?
No. Do not use a waiver to bypass an age restriction, required test or insurance condition. It also does not remove the young person’s ability to say they no longer want the treatment.
Are the rules for joining a course the same as receiving a treatment?
No. Course enrolment, assessment, insurance eligibility and the age of a treatment client are different questions. See our guide to the minimum age for beauty and nail courses for NSB’s enrolment position.
Have all cosmetic procedures now been banned for under-18s?
Do not treat a news announcement as a blanket rule already in force. The government announcement of 21 October 2026 describes proposed further restrictions in England, with consultation and a Parliamentary process still to follow. Existing treatment-specific restrictions continue to matter. Recheck developments before offering advanced procedures.
Build good client habits from the start
Knowing when to pause or decline is part of professional practice. If you are beginning your training, explore our beginner nail courses or online beauty courses. For help choosing a course, ask the NSB team for course guidance. Your insurer and local authority remain the right contacts for the specific cover and regulatory checks described above.
