Hair color consent form: the allergy test, the risks and the aftercare
Most color complaints are not really about the formula. They are about expectations: the photo she loved, the box dye she forgot to mention, the gray that never quite covered. A color consent form is where all of that gets said out loud, and signed, before you mix a single bowl.
This exact form is built into SlickChart: send it to your client's phone to sign before her appointment, and the color aftercare goes home with her.
Say what the service is, and how long it lasts
My form opens with a short "about this service" box: permanent or demi-permanent color to change or refresh a shade, or to blend or cover gray. It sets the time at about 1.5 to 3 hours and says plainly that results depend on hair history and correction may take more visits.
Then the part clients rarely think about at booking: permanent color grows out, with roots showing in 4 to 8 weeks, while demi and gloss fade over 6 to 8 weeks. The client also checks today's service: permanent, demi-permanent, gray coverage, correction or gloss.
Risks she should hear before the bowl
The risk list is written in client language, not chemistry: itching, redness or burning on the scalp; an allergic reaction to the dye, even after years of use; staining on the hairline, ears or neck for a day or two; a shade or tone that differs from the photo she loves; uneven color from past color, box dye or porosity; resistant gray that covers less fully; dryness or a change in feel; and fading, especially red and copper tones.
The photo line does a lot of work: once she has signed that her result may differ from her inspiration picture, the mirror conversation starts from shared understanding.
The health and hair check
The contraindication list mixes scalp, health and hair history. It asks about sores, cuts or sunburn on the scalp; infection, lice or ringworm; a psoriasis or eczema flare; a past reaction to hair dye; a "black henna" tattoo, ever; an allergy to PPD, PTD or dye; box dye, henna or metallic dye; a relaxer, perm or keratin; isotretinoin or minoxidil; hair loss, chemo or radiation; pregnancy or breastfeeding; and asthma or sensitivity to fumes.
A free text box underneath lets a checked item come with context. A check starts a conversation; it is not a verdict, and deciding what a health condition means belongs to the client's physician, not to us.
An allergy alert test before every color
The allergy section is short and firm:
Hair dyes contain PPD, and an allergy can develop at any time. We test 48 hours before every color. Never use hair dye on lashes or brows.
The client records either "Test done, no reaction" or "Declined, waiver signed." I cover the testing form and its waiver in my hair dye patch test form post.
The acknowledgements
She confirms she shared her full health, medication and hair history, including box dye, henna and past chemical services; that her result is not guaranteed; and that she will speak up right away if her scalp burns, stings or itches.
Two lines protect bigger changes: she agrees to a strand test if advised for big changes or unknown history, and accepts that color correction may take more than one session, is priced hourly, and may reach the goal in stages. Photos for her private record are required, with social media use only with her separate OK, and color concerns are raised within 7 days.
Aftercare that protects the color
The guide opens with: the first few days lock in your color. Then it runs in stages:
- First 72 hours: a little color in the rinse water or on the pillowcase is normal. Wait 48 to 72 hours before the first shampoo, and use cool water only if hair must get wet. Skip hot showers, swimming, saunas, heavy sweat and clarifying or dandruff shampoos.
- Weeks 1 and 2: sulfate-free, color-safe products, washing 2 to 3 times a week in cool water. Reds and coppers soften a little first.
- Weeks 4 to 8: book a root touch-up every 4 to 8 weeks and a gloss or toner refresh every 4 to 6 weeks. No box dye between visits.
- Ongoing: trim every 8 to 12 weeks, and avoid henna, "progressive" or metallic dyes, which can react badly with salon color.
The call-me list covers scalp itching, burning or redness; a rash or swelling at the hairline, ears or neck; blisters, oozing or crusting; and hair that feels gummy or breaks easily. Swelling of the face, eyes or throat, or trouble breathing, means calling 911.

Questions to decide for your own practice
- Will you color a client who declines the allergy alert test, or only with the signed waiver?
- Where will you record formula, developer and timing so the next visit matches?
- 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 hair color consent and aftercare built in for hair stylist subscribers. The form goes to the client's phone to sign before the visit, or she signs on your device in the chair, 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.
