1. Choose fast-acting formulas for optimal processing time.

When time is money, it’s best to make every minute behind the chair count. Kelly recommends using Joico’s LumiShine LUMI10™ permanent haircolor to deliver 100 percent gray coverage in just 10 minutes. This fast formula is ideal for those last-minute walk-ins, double-booking clients with ease or hybrid blonding with gray coverage applications.

2. Apply teasylights for a soft, dimensional result.

Kelly’s goal is to give her client a soft, blended look without a ton of contrast. How? Teasylights! After prepping the hair with Joico’s Defy Damage ProSeries 1 Bond-Protecting Color Optimizer Spray, create a basic halo around the surface of the head, following the client’s unique head shape.


Here’s how it’s done:


  1. Start foiling at the top of the head, making sure to avoid any regrowth so you can apply LUMI10™ later. Take larger weaves and finer sections for maximum lift. Remember to leave any prelightened ends out to preserve the integrity of the hair.
  2. Continue foiling down along the hairline, alternating each section until you reach the top of the ear. Don’t place another foil below that point to avoid harsh lines of demarcation.
  3. At the top of the crown, apply two layered teasylights and a third, smaller one in the back for a burst of color.


Pro tip: When foiling the front, make sure your last weave is the hair that falls around the client’s face. This creates a ribbon of dimension around facial features where we want to see brightness.

3. Fully saturate to cover stubborn grays.

Kelly recommends waiting until your foils need 10 to 15 minutes of processing time, then applying generous amounts LumiShine LUMI10™ to regrowth. Make sure to fully saturate the hair, applying underneath each section, and to target the grayest areas first so they have the most time to process.


Pro tip: When applying gray coverage color, take vertical sections when possible to avoid harsh lines and unnecessary staining.




Once processing is complete, cleanse, add a glaze of choice at the shampoo bowl, then complete the look using Joico’s Defy Damage ProSeries 2 Bond-Strengthening Color Treatment to seal everything in.
