Hair Dye Made for Sensitive Scalps

If your scalp reacts to hair color, start here. INOCHROMA is created with sensitive scalps in mind: PPD-free, ammonia-free, and low-odor. It delivers gentle grey coverage with a smooth feel. Always perform a patch test 48 hours before coloring and follow the step-by-step routine below for a calm, comfortable application.

Signs of sensitivity vs. allergy

• Sensitivity (irritation): temporary itching, mild redness, tightness, dryness during/after coloring; usually fades within hours.
• Allergy (contact dermatitis): immune response—itchy rash, swelling (ears/eyelids/neck), blisters; can worsen with repeated exposure and last days.
• PPD (para-phenylenediamine): a common dye precursor in many permanent colors; a known allergen for some people. If you’ve reacted to PPD before, avoid PPD and always patch test. Seek medical help for severe swelling or breathing issues.
  

What we leave out (PPD, ammonia) & why it matters

• No PPD: reduces exposure to a frequent hair-dye allergen, improving comfort for people advised to avoid it.
• No ammonia: lowers harsh odor and potential scalp sting linked to alkaline pH spikes.
• Low-odor, comfort-focused system: designed to blend greys while keeping the scalp experience calm. (Sensitivity varies—review the ingredient list and test first.)
  

Patch test: how to do it right

• 48 hours before coloring, clean/dry skin behind the ear or inner elbow.
• Apply a pea-size amount; let dry. Do not wash the area.
• Observe for 48h: redness, itching, swelling, burning = do not use.
• If clear, proceed. Repeat the test before every application or after any product change.
  

First-time routine: gentle application guide

• Prep: No scratching for 24h; start on dry hair. Apply a thin barrier cream along the hairline. Wear gloves.
• Section fine: 0.5–1 cm sections help precise, light pressure application.
• Apply to roots first: fully saturate visible greys (parting/temples). Avoid rubbing the scalp.
• Timing: follow leaflet (typically 20–30 min). Do not exceed.
• Rinse & care: lukewarm water until clear; use a gentle conditioner.
• Aftercare: color-safe shampoo, cooler water, UV protection; re-apply at roots every 3–4 weeks as needed.

Real stories from sensitive users

• “No sting, low odor—finally comfortable enough to touch up roots at home.”
• “Switched from a PPD formula; patch test was clear, coverage looks natural.”
• “Temples are stubborn—leaving it the full time made a big difference.”
• “I follow the gentle routine: thin sections, don’t overwork the scalp, rinse well—results are soft and even.”

Reminder: “PPD-free” and “ammonia-free” improve tolerance for many users, but no product is irritation-proof. If discomfort occurs, stop use and consult a professional.
