Written by Autumn Schiess, Owner & Lead Stylist at Sølvi Salon
Most of the color consultations we run at Sølvi start the same way. A client sits down, opens her phone, scrolls to a saved photo, and says some version of "I want this, but I don't actually know what it is." Nine times out of ten the photo is either a soft, sun-grown-out blonde or a rich dimensional brunette with face-framing brightness. And nine times out of ten, the answer to what she's looking at is one of two services: a balayage, or a full custom color.
The two get used interchangeably online, which is part of the confusion. They are not the same service, they don't cost the same, they don't take the same amount of time, and they don't grow out the same way. We want to walk through the actual differences from inside the chair so the next time you book with us, or with anyone in Boise, you know what you're asking for.
What Balayage Actually Is
Balayage is a freehand painting technique. The word is French for "to sweep," and that's literally what we're doing. We section the hair, then hand-paint lightener onto the surface in soft, sweeping motions. There is no foil involved in a traditional balayage, though some of us use a film or a board to protect the placement. The lightener processes in open air, which gives you that soft, diffused, sun-kissed effect at the ends without a hard line at the root.
Balayage is a technique, not a full color service on its own. When you book a balayage at Sølvi, what you're really booking is balayage plus a gloss or toner to finish. The painting brightens. The gloss controls the tone so it doesn't read brassy or ashy. Both are needed. We mix Olaplex into every lightener bowl to protect the integrity of the hair during the lift.
The best candidate for balayage is someone whose natural base is already close to where they want their roots to live. If your natural color is a level six light brown and you want bright, lived-in blonde ribbons through the mid-shaft and ends, balayage is the answer. You keep your real root, you add brightness through the lengths, and the grow-out is genuinely seamless. We have clients who stretch their balayage four to six months between appointments because there's no hard regrowth line to chase.
What Full Custom Color Means at Sølvi
Full custom color is the umbrella service we use when a balayage alone won't get you there. It is the service we call The Transformation when the move is significant, and it combines whatever techniques the head of hair in front of us actually needs. That could mean foils through the top and balayage through the back. It could mean an all-over base color first, then highlights or babylights woven through the surface, then a gloss to marry everything together. It could mean a teasylight technique at the root for a soft, blended regrowth on a high-contrast blonde.
Full custom color exists because most real heads of hair don't fit into a single technique. A client with naturally dark hair who wants to be a bright blonde isn't a balayage candidate, she's a lift-and-tone candidate, often across multiple sessions. A client who has been box dying her hair at home for two years and wants dimension back isn't a balayage candidate either, she's a corrective color candidate. A client whose roots have gone gray and whose ends have faded warm needs a root touch-up plus a gloss plus targeted brightness, not a balayage.
The shorthand we use behind the chair: balayage is a single painting technique with a finishing gloss. Full custom color is whatever combination of techniques actually delivers the photo on your phone.
Time, Cost, and How It Grows Out
This is where the practical difference shows up. A balayage with us runs around three to four hours depending on hair density and length. A full custom color, depending on what's involved, can run anywhere from four to six hours, sometimes longer if we're doing a deep corrective. Our pricing is package-based and includes the gloss, the blow-dry, and the Olaplex bond support, so there are no surprise add-ons at checkout. We tell every client the full price at the consultation, before anyone mixes color.
Grow-out matters more than most people think when they're booking. A traditional balayage placed correctly grows out softly because there's no foil-driven brightness sitting at the root. You'll see your real base color emerge gradually, and the painted pieces drift down with the hair. You can comfortably stretch four to six months between full sessions, with a gloss refresh somewhere in the middle if you want the tone to stay cool.
Full custom color depends on the technique mix. If foils are involved at the root, you'll see a more defined regrowth line, and we typically see those clients every eight to twelve weeks for root work. If it's a base color with painted brightness, the base will need touching up before the brightness does. We map all of this out at the consultation so you know what the long-term schedule actually looks like, not just the cost of the first appointment.
Boise Summers and Color Choice
We bring this up at almost every June and July consultation. Boise summers are dry and bright, the UV index sits high for months, and we lose a lot of clients to the river, the foothills, and the pool. All of that fades color, especially blonde. Brassiness is the most common summer complaint we hear in the chair, and it's worse the more lift we've done.
A balayage handles a Boise summer beautifully because the brightness is concentrated through the mid-shaft and ends, where some softening from sun exposure actually reads as more natural. A full custom color that includes a lot of foiled brightness through the top will fade faster in the sun and may need a gloss refresh sooner than you'd planned. None of this is a reason to avoid one or the other, it's just something we factor in when we're mapping out a yearlong color plan in June versus December. If you spend your summers outside in Boise, we'll often suggest a slightly cooler tone at your spring appointment so it has somewhere to fade to.
How to Decide Which One to Book
The shortest answer: if you want your natural root to stay where it is, and you want soft brightness through your lengths with the longest possible grow-out window, book a balayage. If you want significant change from your current color, if your hair has color history we need to work with, or if you want a defined, polished result with brightness placed right up at the root, book a full custom color consultation.
When you're not sure, book a consultation first. We do free fifteen-minute color consultations in our loft on Capitol Boulevard where we can actually look at your hair in our natural light, look at your inspiration photos together, and tell you honestly which service will get you there. It is much better to spend fifteen minutes upfront than to book the wrong service and feel disappointed at checkout.
Ready to Book
If you already know what you want, you can book either service directly on our site. If you're somewhere in between or working with color history, start with a consultation and we'll build the right plan from there. Call the salon, message us, or book online, whichever is easier. We're a small team by design, so when you sit in the chair, you have our full attention from the first section to the final blow-dry.
