4 Critical Points to Add to Your Consent Form

One of the first things I tell every lash artist who trains with Lash Affair is this: before you ever pick up your tweezers, you need a solid consent form. I've been running Lash Affair since 2014, and I can tell you from experience that a well-crafted consent form isn't just a legal formality, it's the foundation of a professional, trust-building client relationship. It also pairs directly with the legal protection steps covered in the lash business start-up guide -- licensing, insurance, and client documentation all work together to keep your business safe. Here are the four critical points every lash artist's consent form should include.

1. Permission to Share Client Photos

Your before-and-after photos are some of the most powerful marketing tools you have as a lash artist, but you need written permission before sharing them anywhere. Your consent form should clearly outline:

• Who will have access to the client's photos (you, your studio, your brand)
• What photos will be taken and shared
• How the photos will be used (social media, website, portfolio, print marketing)
• Why you're requesting permission (promotional content, educational demonstrations)

Keep the language simple and client-friendly. I always recommend including a separate checkbox or signature line specifically for photo consent so clients don't feel pressured, they should be able to decline photo sharing while still receiving your services. Being transparent about photo usage builds trust and often leads to clients being more willing to share, not less.

2. Medical History and Health Disclosures

This is non-negotiable. Your consent form must ask about medical conditions that could affect the lash application or the client's safety. Key questions should cover:

• Eye conditions such as blepharitis, conjunctivitis, styes, or dry eye syndrome
• Recent eye surgeries (LASIK, cataract surgery, blepharoplasty)
• Skin conditions like eczema, psoriasis, or dermatitis around the eye area
• Autoimmune disorders such as alopecia or trichotillomania
• Pregnancy or nursing status (hormonal changes can affect lash adhesive retention)
• Current medications, especially those affecting skin sensitivity or hair growth

I've had clients over the years who didn't initially disclose conditions that directly impacted their retention or caused sensitivity. Having these questions on paper ensures you've done your due diligence and gives you documentation if any issues arise later.

3. Allergy Awareness and Patch Test Documentation

Allergic reactions to lash adhesive are rare but real, and your consent form is where you address this head-on. Include a section that:

• Lists the primary ingredients in your adhesive (especially cyanoacrylate and carbon black)
• Asks whether the client has any known allergies to adhesives, latex, or cosmetic products
• Documents whether a patch test was performed and the results
• Explains the signs of an allergic reaction and what to do if one occurs
• Includes a waiver acknowledging the client understands the risks

At Lash Affair, we always recommend performing a patch test for first-time clients, especially those with sensitive skin or a history of allergies. Document the patch test date and results directly on the consent form, this creates a paper trail that protects both you and your client.

4. Service Expectations and Aftercare Agreement

The fourth critical section covers what the client can expect from their service and their responsibilities for aftercare. This section should address:

• Estimated application time and what the service involves
• Expected retention timeline and when fills are recommended
• Aftercare instructions: avoiding water for the first 24 hours, no oil-based products near the eyes, daily cleansing with a lash-safe cleanser
• Activities to avoid (steam rooms, saunas, heavy sweating for 24 to 48 hours post-application)
• A statement that results vary based on natural lash health, lifestyle, and adherence to aftercare

When clients sign off on aftercare expectations upfront, it dramatically reduces complaints about retention. I've found that clients who understand their role in maintaining their lash extensions from day one are far more satisfied and much more likely to rebook.

Bonus: Make Your Consent Form Work for Your Business

Beyond the legal essentials, your consent form is a touchpoint that sets the tone for the entire client experience. Consider adding a section for the client's contact information and preferred communication method so you can follow up with rebooking reminders or aftercare check-ins. You can also include an optional email opt-in for promotions and new service announcements, this turns your consent form into a lead-generation tool.

Frequently Asked Questions

Do I legally need a consent form for lash extensions?

Requirements vary by state and country, but regardless of local regulations, a consent form is considered best practice in the lash industry. It protects you from liability, documents the client's informed consent, and demonstrates professionalism. Many insurance providers require consent forms as part of their coverage terms.

How often should I update my consent form?

Review your consent form at least once a year or whenever you change products, add new services, or learn about new regulatory requirements. If you switch to a different adhesive brand or formulation, update the ingredient disclosure section immediately.

Should I use a digital or paper consent form?

Both work, but digital consent forms offer advantages: they're easier to store, search, and back up. Many booking platforms include built-in consent form features. If you use paper forms, keep them organized and secure to comply with privacy best practices. Whichever format you choose, always keep consent forms on file for at least three years.

What should I do if a client refuses to sign the consent form?

If a client refuses to sign, you should politely decline to perform the service. The consent form protects both parties, and performing services without documented consent puts you at legal and professional risk. Explain that the form is standard practice and designed to ensure they have the best possible experience.
