Alfaparf Mixing Ratios: Evolution 1:1.5, Platinum 1:2

What are the Alfaparf mixing ratios?

Alfaparf Milano is the line most often mixed wrong by someone who already knows it. Evolution of the Color — the permanent everyone means when they say “Alfaparf” — mixes 1:1.5. Nearly everything else in the range mixes 1:2: the Platinum high-lift series, the Harmonizer post-bleach toners, Color Wear and the Color Wear Gloss Toner.

So the useful rule is not a number. It is that 1:1.5 belongs to Evolution specifically, and the moment you reach for a lightening or toning product in the same range the ratio moves.

Why does Evolution of the Color mix 1:1.5?

1:1.5 means 60 g of colour to 90 ml of Oxid'o, giving 150 g of mix from a standard tube. Processing is 35 minutes. Alfaparf states 100% grey coverage and up to 3 levels of lightening for the line at that ratio.

The half-part is doing real work. It buys a more fluid mix than a 1:1 permanent without dropping to the dye density of a demi — enough oxidant to carry three levels of lift, enough pigment left in the bowl to cover grey completely. Lines that mix 1:1 generally claim less lift; lines that mix 1:2 are generally depositing rather than covering.

Which Oxid'o volume for which result?

• 10 vol (3%). Tone-on-tone. Depositing at level, no lift.
• 20 vol (6%). Coverage, and one to two levels of lightening. The default for most grey work.
• 30 vol (9%). Two to three levels of lightening.
• 40 vol (12%). Three to four levels, and the only oxidant the Platinum series takes.

Oxid'o is also made in 5 vol, which is not a colouring strength — it exists for the Harmonizer toners, where the job is to tone with as little lightening as possible. How to read the shade code itself is here.

What ratio does the Platinum series mix at?

1:2 — 60 g of Platinum to 120 ml of 40 vol Oxid'o, processing 50 to 55 minutes. Alfaparf restricts it to natural bases no darker than level 5, and on its own it lightens natural hair by 4 levels.

Mixed in equal parts with the Super High Lifting Reinforcer (0SP) it reaches up to 5 levels: 30 g Platinum, 30 g 0SP, 120 ml of 40 vol Oxid'o. Note what stays constant there — the reinforcer replaces half the colour, not any of the oxidant, so the mix is still carrying the full 1:2 of peroxide.

There is a separate Lifting Reinforcer (000SSS) for the ordinary Evolution shades, mixed in equal parts to buy about one extra level. It does not work with Platinum, and Platinum's own reinforcer does not work with the standard shades.

Why does Color Wear invert for grey?

Color Wear is Alfaparf's tone-on-tone line and mixes 1:2 with Color Wear Activator. The exception is worth memorising: for 100% grey coverage the ratio moves to 1:1, blended with the same amount of the natural base.

That is the same physics as everywhere else in colour, expressed as a ratio change instead of a developer change. A 1:2 demi is deliberately dye-poor. Grey has no pigment of its own to sit under the deposit, so the fix is more pigment in the bowl — which, in a system with one activator strength, means less activator. The grey percentage maths is here.

What does the Gloss Toner mix at?

1:2 with Gloss Toner Activator, a 9.5 vol (2.85%) stabilised liquid peroxide made for this product and nothing else. Five minutes gives a flash tone at the backwash; twenty gives maximum intensity.

It can go on wet or dry hair, and dry reads more intense — a useful control to have when the alternative is reformulating. What it cannot take is a cream developer from elsewhere in the range: the activator is liquid, at a strength no Oxid'o is made in.

Which Alfaparf ratio mistakes cost you the service?

• Mixing Platinum at 1:1.5. The commonest one, and it comes from knowing the brand rather than not knowing it. A third less oxidant than the system needs, on the one service in the range with the least margin — the lift stalls warm.
• Color Wear at 1:2 on solid grey. The line covers grey at 1:1. At 1:2 it is a tone-on-tone mix doing a coverage job, and it will slide off within a few washes.
• An Oxid'o cream in the Gloss Toner. Wrong form and wrong strength. The Gloss Toner Activator is a 9.5 vol liquid; Oxid'o is not made at 9.5, so there is no equivalent to reach for.
• Stretching a bowl with extra Oxid'o. At 1:1.5 the margin for this is smaller than it looks — you are moving toward 1:2 and out of the coverage the tube promises. Mix a second bowl.
