How Long Does it Take to Process Paul Mitchell Colour?

What You Need to Know Before Your Appointment

When you book a colour appointment with a salon that uses Paul Mitchell colour, one of the top questions is: how long will it take to process? You want gorgeous colour, not endless waiting. Good news: it doesn’t always have to take hours. But the time depends on which line you’re using, what your hair’s condition is, and what result you’re after. Let’s break it down so you go in informed, and your stylist knows you mean business.

Quick Answer

Here’s the short version:

• For the “express” line The Color 10: about 10 minutes, maybe up to 20 minutes.
• For the standard permanent line Color XG:
• Deposit/minimal lift: ~ 25 minutes.
• 1-2 levels of lift / regular coverage: ~ 35 minutes.
• 2-3 levels of lift: ~ 45 minutes.
• 3-4 levels of lift or very resistant hair: ~ 45-55 minutes.

So, if your stylist says, “we’ll be done in 10 minutes”, you’re likely on the express line. If it’s a full head, lift, lots of grey or dramatic change, expect more like 35-45 mins (or more).

What Delays How Long It Takes?

Here are the real factors that change processing time:

1. Colour line / product used

• The Color 10 is built for speed and grey blend/retouch, it says “process for 10 minutes; up to 20” on the instructions.
• Color XG gives a range of times depending on lift & volume.

2. Developer strength / lift required
If you’re just depositing tone, you’ll need lower volume developer and less time. If you’re lifting (going lighter) you need higher strength and more time. The Color XG chart shows exactly that.

3. Hair condition & base level

• Lots of grey or very resistant hair = longer time. For instance, the CoverSmart sub-line of Color XG says “35 minutes without heat, up to 45 minutes for very coarse white hair”.
• Previously coloured hair, damaged hair, or thick texture can all affect time.

4. Coverage goal vs quick fix

• If you’re doing a quick root refresh or minor change: shorter time.

• If you’re doing major transformation (e.g., going lighter, correcting) expect longer time.
• The express line (The Color 10) is not designed for heavy lift or high resistance, it’s for levels ~3-7 & 40-60% grey according to the brand. (SalonEVO)

5. Application & environment
Clean, dry hair, correct mix ratio, no extra heat = the time listed. If your hair has complicating factors, the stylist may adjust. For example, The Color 10 instructions say “apply to dry hair… process for 10 minutes” without added heat.

What This Means for You

Here’s how to use this info so you don’t end up surprised:

• If you’re booking your appointment: Ask what line they’re using (The Color 10 vs Color XG). That gives you a clue to how much time.
• If your hair is mostly grey / very resistant: Be realistic, even the fast lines may need more time.
• If time is tight (e.g., brunch with the girls at 1pm): Consider that the 10-minute express line exists, but make sure you match your hair condition & goal to that service.
• If you want a dramatic change: Build in extra time. Your “process” time is only part of the appointment (application, rinse, finishing etc add up).
• Confidence in your stylist: Knowing the expected processing time helps you chat about booking realistically, and prevents feeling rushed or wondering “why are we still waiting?”

Final Thoughts: Setting Expectations & After-Care

• Time is only one part of great colour, correct formulation, application, after-care matter too.
• After processing, you’ll still need rinse, shampoo/condition and styling, so plan appointment length accordingly.
• Once colour’s done, use colour-protect shampoo/condition (look for the brand’s own after-colour care) to maintain your result.
• For consumers: being informed = showing the stylist you know your stuff and getting what you booked.
