Grey Hair Dye Checklist: PPD-Free, Ammonia-Free for Sensitive Scalps

Grey Hair Dye Checklist: Make Safer, Smarter Choices

If you have a sensitive scalp, start here. Use this quick checklist to pick PPD-free, ammonia-free, low-odour colour. Decide between grey blending and full coverage. Learn label tips and a simple 24-hour patch test.


Quick Buyer’s Checklist

  • Skin history: Ever reacted to dye? Choose PPD-free, ammonia-free, and fragrance-free.
  • Patch test: Do a 24-hour test before first use or shade changes.
  • Desired result: Grey blending for soft, natural look. Full coverage for solid shade.
  • Shade plan: Stay close to your natural level. Cool tones mute brass. Warm tones add softness.
  • Formula type: No-mix for speed and comfort. Mix-at-use for stronger cover.
  • Odour & fumes: Pick low-odour systems for daily comfort.
  • Scalp comfort: Look for “hypoallergenic”, “sensitive scalp”, and soothing additives.
  • Time & upkeep: Weekly top-ups for blending. 3–5 weeks for root cover.
  • Budget: Check cost per use, not only sticker price.

Decode the Label (INCI)

Read the ingredient list. These points help:

  • Absent: PPD (p-phenylenediamine), heavy fragrance/parfum, harsh ammonia.
  • Consider: PTD、resorcinol、MEA—some users still react. Patch test first.
  • Good signs: Conditioning agents, mild surfactants, scalp-friendly pH.
  • Claims: “PPD-free”, “ammonia-free”, “no-mix”, “low-odour”, “hypoallergenic”.

Blending vs Full Coverage

  • Grey blending: Softens white strands. Hair stays natural. Fade is gentle.
  • Full coverage: Opaque results. Best for high % grey or big shade change.
  • Face hair / temples: Often need longer time or targeted product.

No-Mix vs Mix-at-Use

  • No-mix: Faster. Great comfort. Ideal for maintenance and sensitive scalps.
  • Mix-at-use: More control on developer strength. Better for resistant greys.

24-Hour Patch Test (Fast Steps)

  1. Clean a small spot behind ear.
  2. Apply a pea-size amount. Let dry.
  3. Leave for 24 hours. Do not wash.
  4. Redness, burning, or swelling? Do not use.

Application Basics

  • Work on dry hair. Section first.
  • Start where grey is most visible.
  • Coat evenly from roots. Do not oversaturate ends.
  • Process as directed. No heat unless the label says so.
  • Rinse until water runs clear. Then gentle shampoo and condition.

Care & Upkeep

  • Use a colour-safe, hypoallergenic shampoo.
  • Condition each wash. Add a weekly mask if hair feels dry.
  • Limit hot tools. Heat fades tone fast.
  • Top-up grey blending weekly. Do root coverage every 3–5 weeks.

FAQs

Will PPD-free colour last?

Yes. Wear depends on wash habits, shade, and porosity. Blending fades softer than full cover.

Is no-mix strong enough?

For many users, yes. It excels at maintenance and comfort. Very resistant greys may need mix-type.

Can I use it on a beard?

Do a fresh patch test. Use short times and avoid skin overlap.
