Reading Pigment Strength Across the Iroiro Line
Iroiro sells vivid dyes and a color-depositing shampoo, and buyers often cannot tell which their situation needs. The strength ladder is simple. The 105 Plum and 20 Purple dyes carry the heaviest pigment for full transformation, showing true color on pre-lightened hair. The 210 Pastel Lavender carries less pigment and needs a near-white base to show at all. The Lavender Color Depositing Shampoo sits at the bottom: it maintains tone between dye sessions but cannot create the color on its own. Buying the shampoo expecting dye results is the most common disappointment in this line.
Judge shades the way you judge purple shampoo. Deep, dark product in the jar means strong pigment and fast processing. Pastel shades process slower and fade faster, needing more frequent refreshes. The depositing shampoo follows toning rules: two to three minutes maintains, five minutes corrects, longer soaks risk a lavender cast on porous hair. Our best purple shampoo guide explains the same strength logic for toning shampoos.
When Toning Stops Working
If the Lavender Color Depositing Shampoo kept your purple fresh for months and suddenly stops, the bottle is rarely the problem. Three causes, three fixes. First, mineral buildup: hard water film blocks pigment from depositing. A chelating wash before your next toning session tests this. Second, porosity drift: hair gets more porous with heat and sun, grabbing lavender unevenly for patchy results. Third, base shift: regrowth or fading changed the underlying level, so the same lavender now sits on a different canvas.
Fix in order. Chelate first, since it is the cheapest test. If tone returns, chelate monthly. If color is patchy, do one full refresh with 105 Plum or 210 Pastel Lavender to reset the base evenly, then return to the shampoo for maintenance. If the tone looks wrong in a way you cannot name, a salon gloss resets the base fastest. For brass on blonde rather than purple maintenance, the Amika purple guide covers toning plus strengthening.
Shampoo or Dye: The Format Decision
Choose the dye when you want a visible color change, when your purple faded past what maintenance can fix, or when starting fresh on pre-lightened hair. Choose the depositing shampoo when your purple is already right and you are fighting normal weekly fade, when you want to stretch time between dye sessions, or when hair is too damaged for another full process right now. Wash frequency decides how well the shampoo strategy works: daily washers get beautiful top-ups from it, while twice-a-week washers get more even results from a monthly dye refresh.
Damaged, high-porosity hair grabs shampoo pigment fast, so keep contact times short to avoid a lavender cast. Healthy, low-porosity hair may find the shampoo barely deposits, in which case the full dye is the honest answer. Match the format to your hair, not the price tag. Travel note: hotel water in a new city can accelerate fading, so pack the depositing shampoo rather than the full dye. Deeper maintenance routines are in the blonde toning mask guide.

Shampoo Technique Matters More Than You Think
Picking between the IROIRO Premium Natural Semi-Permanent Hair Color 105 Plum and the IROIRO Premium Natural Semi-Permanent Hair Color 210 Pastel Lavender is only half the job, because the way you lather, rinse, and repeat decides how either formula performs.
How much shampoo should I actually use?
Start with about a quarter-sized amount for short to medium hair, and add more only if the lather feels thin. The IROIRO Premium Natural Semi-Permanent Hair Color 105 Plum and IROIRO Premium Natural Semi-Permanent Hair Color 210 Pastel Lavender both spread best on fully wet hair, so soaking your strands first usually means you need less than you think.
