Lash extension consent form: what to include, from the lash map to the aftercare
Lash extensions are the longest appointment on my lash menu. The client spends it lying still with her eyes closed while you work with adhesive right at the lash line. Then she goes home and decides, daily, whether to rub, pick or oil her way through your work. A good extension consent covers both halves: what happens on your bed, and what happens after.
This exact form is built into SlickChart: send it to your client's phone to sign before her first set, and the aftercare goes home with her.
Explain the service before the risks
My form opens with what she is agreeing to: single extensions (classic) or light fans (volume, hybrid) bonded to her natural lashes with adhesive. Then the practical part. A set takes about 1.5 to 2.5 hours lying down with eyes closed, under-eye pads protect the lower lashes, and extensions shed with the natural lashes, so fills every 2 to 3 weeks keep the set full.
Risks, including the one clients do not expect
The risk list names adhesive allergy (puffy, itchy or red eyelids), red or watery eyes from adhesive fumes, irritation if pads or tape shift, infection (more likely without daily cleansing), natural lash damage from extensions that are too heavy, lash loss from picking or home removal, and rarely, a minor eye injury from tools.
The line I would never leave out:
Allergy can start after many sets without issue.
Long-time clients often believe they cannot react because they never have. The form says otherwise, and the patch test line backs it up: the client confirms she was offered an adhesive patch test and that a clear test doesn't rule out a reaction later. More on that in my lash and brow patch test form post.
The same section separates shedding from damage: 1 to 5 natural lashes a day is normal, and extensions come out with them.
A health check built for the eye area
My lash-specific health check asks about an eye infection, stye or pink eye; blepharitis or a dry eye flare; eye or eyelid surgery, including LASIK; allergy to adhesive, latex or tape; sensitive skin or eczema near the eyes; pregnancy or breastfeeding; chemo; alopecia or trichotillomania; lash serum or glaucoma drops; contact lenses; asthma or fume sensitivity; a lash lift or tint in the past 2 weeks; another artist's extensions; and trouble lying flat for 2 hours.
These answers start a conversation; they are not a way to name a condition. If an eye looks wrong, refer out.
Agree on the look, in writing
The consent has a style approval: client and artist agreed on style, length and curl, and the artist may adjust to protect the natural lashes. For the details, I pair it with a separate lash map: lengths per zone for each eye, style, type, curl, diameter, the condition of the natural lashes, eye shape, and the lash brand, adhesive and lot number. The client signs that she chose her style, and that extensions must suit the strength of her natural lashes.
The map doubles as your product record if she reacts weeks later. Here is more on what to record in a client chart.
The acknowledgements that protect her lashes
The client agrees to keep her eyes closed and say right away if anything stings or burns; to contact you and have the set removed professionally if her lids swell, itch or turn red; that retention varies with skin, hormones and habits and isn't guaranteed; and that she will not pick, pull or remove extensions herself. A fill rule (40% of extensions left, or it is charged as a full set) and photo permissions follow.
If a set ever needs to come off, my separate removal consent covers it, including that anyone who suspects an adhesive allergy sees a doctor before a new set.
Aftercare: curing first, then daily habits
The guide explains that the adhesive keeps curing for the first day or two, then walks through the weeks:
- First 24 to 48 hours: keep lashes dry for 24 hours, no steam, saunas or sweaty workouts for 48, and brush with a clean spoolie.
- First week: start daily cleansing with lash-safe foam, and keep oil-based products, mascara and curlers away.
- Weeks 2 to 3: expect gaps, mostly at the outer corners, and come to the fill with clean lashes.
A second retention guide covers the growth cycle and a four-step cleanse. Both end with when to call: puffy, itchy or red lids even days later, a rash, discharge or crusting, or redness that keeps getting worse. Eye pain or vision changes mean urgent eye care, and trouble breathing or face or throat swelling means 911.
Questions to decide for your own practice
- Will you patch test every new client, or offer it and record the choice?
- What is your fill window, and how will you handle a fill that has dropped below your rule?
- What does your state board require? Consent rules and scope of practice vary by state, so check with yours. This post is not legal or medical advice.
Use this form with your clients
SlickChart has this exact lash extension consent, lash map and aftercare built in for subscribers. The form goes to the client's phone to sign before the visit, or she signs on your device in the room, and any contraindication she checks is flagged for you. The aftercare lands in the client's own app, styled with your logo, and it all works alongside the Square account you already have. If that would save you paperwork, try SlickChart.
