Henna Brow Contraindications: What to Spot Before You Treat

A good intake prevents 90% of problems with henna brows. Yet many brow professionals limit the intake to "do you have allergies?". That is too short. A number of contraindications are not allergic in nature but medically relevant — and you are the one who should recognise them before the paste goes on.

Screening comes first, preparation second. Once a client is cleared to treat, your pre-treatment step sets up an even, long-lasting result.

Skin conditions around the brow

Active eczema, psoriasis, rosacea or contact dermatitis in the brow zone are direct contraindications. At those moments the skin is damaged, permeable and reactive — which strongly raises the risk of irritation, uneven pigment uptake and a worsening of the condition.

The same goes for sunburn, an active herpes outbreak, cold sores near the brow, or open wounds from tweezing. Wait until the skin is fully recovered — usually two to four weeks — before you treat. A short photo record in your intake form is good evidence should any discussion arise later.

Recent cosmetic procedures

Botox and fillers in the forehead or brow zone call for at least two weeks' wait. A chemical peel or microdermabrasion even four to six weeks. Microblading or permanent make-up in the brow zone: at least four to six weeks ago, and even then, discuss with the client whether henna or hybrid still adds value on an already pigmented brow.

Laser therapy and IPL on the face make the skin extra sensitive. Here: at least two weeks after the last session, and always a patch test if you are in doubt.

Medication and health factors

Clients on Accutane (isotretinoin) or other systemic retinoids have strongly thinned, dry skin that reacts differently to tinting. Keep at least six months after the last dose. Chemotherapy and radiation to the head and neck area are also contraindications — not only for the skin reaction, but because hair growth can be uneven.

Pregnancy is a grey area. Henna itself contains no proven harmful ingredients, but the mixing liquid and any colour boosters can be reactive. Many salons choose not to tint in the first trimester, and in the second and third only after explicit written consent and a fresh patch test.

Previous reactions and hypersensitivity

A client who has reacted to hair dye with PPD (paraphenylenediamine) in the past is an important signal. PPD allergy is cross-reactive with some tint ingredients. Always ask specifically: "Have you ever reacted to hair dye, henna tattoos or brow tinting?" — not just "do you have allergies?".

When in doubt: decline the treatment or work with an extended patch test (72 hours instead of 48). That costs you one appointment, but prevents a claim that damages your insurance, your reputation and the client's trust.

What this means for your intake process

Make a fixed intake list with these categories: skin conditions, recent procedures, medication, pregnancy, previous reactions. The Brow Academy offers background on safe application of Marie-José tint products to underpin your protocol.

Step 1 — Run through the categories

Ask through each category out loud; do not rely on a single "any allergies?" question.

Step 2 — Have the client sign

Let the client sign the completed form, and add a patch test where indicated. See our patch test protocol.

Step 3 — Store the document

Keep the signed intake for at least five years as part of your records.
