Brow tint and henna consent form: patch tests, the FDA note and skin stain
Brow tint and henna brows sound like the same service to most clients. They aren't, and the difference shows up a week later, when one client's skin stain is long gone and the other's is still filling in her brows. My brow tint and henna consent treats them as two services on one form, so each client knows which she chose and what it will do.
This exact form is built into SlickChart: send it to your client's phone to sign before the visit, and the aftercare goes home with her.
Two services, one form
The form records which service the client is booking, then explains both. Brow tint is a dye that colors the hairs. Henna brows color the hairs and stain the skin for a fuller look. The appointment takes about 30 to 45 minutes, including shaping.
The timing is where they split:
- Tint: hair color 3 to 6 weeks, skin stain 1 to 2 days.
- Henna: hair color 4 to 6 weeks, skin stain up to 2 weeks.
A client who dislikes visible color on her skin needs to know henna's stain lingers.
A patch test 48 hours ahead
My form states it plainly: a patch test 48 hours before is required. Later the client confirms she had one at least 48 hours ago, or signed the waiver, and that a clear test doesn't rule out a reaction.
If you haven't built a patch test record yet, see my lash and brow patch test form post.
Risks, and the off-label note
The risk list covers an allergy to PPD or dye, even after past tints; redness, itching or stinging on the brow skin; a shade darker, warmer or cooler than expected; an uneven or patchy skin stain; faster fading on oily skin or with exfoliants; and dye in the eye, which is rare and flushed at once.
The same section holds the regulatory note:
In the US, no color additive is FDA-approved for tinting brows or lashes (FDA has reported serious eye injuries from tints), so tint and henna are used off-label at your informed choice; some states restrict this service.
The client then signs a separate line saying she has read that note and chooses to go ahead. Don't copy anyone's FDA wording, mine included. Check the FDA's current guidance on color additives, and ask your state board what it allows, since my form itself notes that some states restrict this service.
A health check centered on dye reactions
Three of the first items on my list are about reactions: allergy to hair dye, PPD or henna; a past reaction to a tint or patch test; and a reaction to black henna. The rest covers an eye infection, stye or pink eye; eye or eyelid surgery in the past 3 months; broken skin or sunburn on the brows; eczema or psoriasis near the brows; retinoids or acids in the past 7 days; a peel or laser in the past 2 weeks; pregnancy or breastfeeding; chemotherapy; alopecia or hair pulling in the brows; microblading or powder brows; very sensitive skin or many allergies; and contact lenses, removed for the visit.
A checked box starts a conversation, not a diagnosis. Refer out anything that looks medical.
Shade and shape approval
Color takes weeks to fade, so my form asks the client to confirm she has seen her shade and mapped brow shape in a mirror and approves both. Two more acknowledgements set expectations: color depends on her hair, skin and aftercare and isn't guaranteed, and brows look boldest on day one and soften.
My separate brow design sheet records natural hair color, undertone, shade goal, and the product, shade and mix, lot number and processing time. You will want that note whether she reacts or asks for the same again. More on what to record in a client chart.
Aftercare that protects the color
- First 24 to 48 hours: keep brows dry for 24 hours (henna: 24 to 48), no brow makeup for 24 hours, and no steam, swimming or oil cleansers.
- Days 2 to 14: tint stain is gone in a day or two, and henna stain fades gradually, faster on oily skin. Use a mild, oil-free cleanser, and keep scrubs, peels, retinol and acids off the brows.
- Weeks 3 to 6: color softens and new hairs grow in uncolored. Rebook for fresh color, shade brows from strong sun.
The call-me list covers itching, burning or redness that gets worse; swelling of the brows or eyelids; a rash, bumps or blisters; and oozing, crusting or skin that feels hot. Color in the eye: rinse with clean water. Eye pain or a vision change means urgent eye care, and trouble breathing or face or throat swelling means 911.
Questions to decide for your own practice
- Does your state allow brow tint and henna, and with which products?
- Will you re-test whenever you change brands or shades?
- 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 brow tint and henna consent 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.
