Free Safety Notes and your honest verdict first. No bleach claims, no risk scores.

What you get free, and what's in your Color Read

Safety comes first and never sits behind a payment. The deeper read is the paid step, and it never tells you a risky plan is safe.

Always free — Safety Notes

Check the risk before you mix

  • Patch-test and strand-test reminders for your plan.
  • Stop-condition warnings for allergy, scalp, and pro-only cases.
  • What to avoid for your starting hair and old color.
  • Your honest verdict: Soft go, Strand test first, Pause and soften, or Salon zone.

How it works

A short consult builds your Hair Passport, then names a realistic lane, saves the receipt, and reminds you when the color settles.

Four honest answers before dye day

Shade Diary names the realistic lane instead of promising a result. No numbers, no risk score — a plain verdict you can act on.

Soft go

Realistic at home. Track it and follow the product instructions.

Strand test first

Likely workable, but one hidden strand should decide.

Pause and soften

The reference asks too much from your current hair. Soften the goal.

Salon zone

Major lift or correction. This one is safer with a professional.

Common questions

Will cherry cola or cowboy copper show on dark brown hair?

It depends on your starting level and any old dye. On dark brown hair a deposit-only red often reads as a subtle sheen indoors and only turns visibly red in sunlight. Shade Diary gives an honest verdict based on your starting base before you commit.

Do I need to bleach my hair first?

Often no for darker, deposit-only shades, but bright or much-lighter results usually need lift. Shade Diary asks whether you want to avoid bleach and flags when a goal crosses into pre-lightening or pro-only territory instead of promising a result.

Is the safety check free?

Yes. Safety Notes — patch-test and strand-test reminders, stop-condition warnings, and your honest verdict — are always free and shown before any purchase. The detailed Color Read shade lane and dye-day receipt are the paid step.

What does a Color Read tell me?

Your realistic shade lane on your current hair: what the color becomes, what shows indoors versus only in sunlight, what to avoid, and your next dye-day move — in plain language, not a risk score.
