When it comes to creating seamless, dimensional blonding, getting the tip-out just right can make or break your final result. Ahead, Asil Simsek (@asil), educator, salon owner and global ambassador for TRUSS Professional, shares the techniques he relies on to create clean, controlled tip-outs every time.
Want to see where these techniques lead? Here’s the finished result from Asil’s Foilayage Blueprint for Levels 3-4 class on BTC University:

Mistake #1: Not Cutting The Hair Before Foiling
One of Asil’s biggest tip-out secrets starts before the lightener is mixed. “When you prep the hair—cutting a little, adding some texture—you’re setting yourself up for success,” he explains.
For blunt cuts with little movement, teasing and detangling can become more difficult during the blonding process. To avoid this, Asil uses his ARC™ Scissors Curve to create soft layers and texture before lightening. The Curve’s precision tip allows him to remove weight exactly where needed, creating movement that makes the hair easier to tease, foil and detangle.

Mistake #2: Your Foiled Sections Are Too Narrow
“You really want to go full with the saturation. Don’t be shy. There is a lot of teasing that’s going to support the blend, so don’t be scared. You can go all in with the application.”

To support that saturation, Asil relies on wider, custom-cut foils that give him more room to spread the hair out during application. “The width of your foils makes a huge difference when you do your application. You want to be able to open up these strands and get them away from each other. The more space they have, the easier they’re going to lift.”
Rather than focusing on section thickness alone, Asil uses his brush to separate and lay the strands out inside the foil, creating a thinner, more evenly saturated layer. “It’s not about the thickness of your section; it’s about how much saturation you do and how much space is in the foil.”
Mistake #3: Causing Product Expansion Inside the Foil
For this look, Asil combines TRUSS Professional blanc.blonde and air.libre Lighteners. “Blanc.blonde has a blue pigment base that eliminates orange undertones, while air.libre is packed with eight oils for a healthy, moisturizing lift,” he says. Together, they deliver the perfect balance of lift and care, especially for porous or previously colored hair.
Asil always adds TRUSS 8x Powder Bond Builder into his lightening formulas. “This bond builder integrates seamlessly with powder lighteners, ensuring the consistency stays perfect without compromising the lift,” he explains. “You don’t want the lightener to expand or change form inside the foil,” he advises, so carefully formulate and fully saturate sections.
These tip-out strategies are just one part of Asil’s complete foilayage system.
