Your Color Is About to Face Its Biggest Test of the Year. Here's How to Make It Last.

Summer looks great on everyone. What it does to color-treated hair is a different story.
If you've ever noticed that your color looks a little duller, a little brassier, or a little flatter by mid-July than it did when you left the salon in May — that's not your imagination. Summer is legitimately the hardest season for color-treated hair, and most people don't think about it until the damage is already done.
The good news: a little preparation goes a long way. Here's what's actually happening to your hair this time of year, and what we'd tell you to do about it.
What summer is doing to your color (even when you're not at the pool)
UV exposure is the most obvious culprit — but it's not just pool days. Daily sun exposure on your commute, at outdoor events, on a walk — it accumulates. UV rays break down the color molecules in your hair the same way they fade fabric left in a window. The result is color that lifts unevenly, goes brassy faster, or loses its depth before your next appointment.
Then there's humidity. For color-treated hair, high humidity means the hair cuticle opens and closes repeatedly throughout the day as moisture moves in and out. When the cuticle isn't lying flat and sealed, color fades faster — and hair feels rougher, tangles more easily, and loses its shine.
Heat styling adds to it. Graduation season, weddings, outdoor dinners — June and early July are full of events where you want your hair to look its best. More heat tool use on top of environmental stress compounds quickly.
None of this is catastrophic. But it is cumulative. The clients who protect their color going into summer are the ones whose hair still looks great at their August appointment — not like they need an emergency fix.
The appointment that changes everything: timing your color before summer
The single most effective thing you can do for your color heading into summer is time your appointment well.
Coming in for a color service before summer kicks in — rather than waiting until you notice the fade — means you're starting the season with fresh, sealed, healthy color. It also means your stylist can do a quick assessment of your hair's current condition and make any adjustments before three months of sun and heat have their way with it.
If you're planning to be at outdoor events in June — a graduation, a wedding, an afternoon on the water — this is the appointment to book now. Color done the week before an event, on hair that's in good condition, will photograph beautifully and hold up for a full day in heat and humidity the way color done on compromised hair simply won't.
What to do at home between now and your next appointment
The products you're using right now matter more than most people realize — especially in the months heading into summer.
Protect before heat styling.
A heat protectant isn't optional for color-treated hair, and it's not just about preventing breakage. Heat damage and color fade are related — when the hair shaft is compromised from heat, it holds color less effectively. Apply before every blow-dry, flat iron, or curling iron, without exception.
Use a color-safe, sulfate-free formula.
This is the one we come back to the most. Harsh sulfates in everyday shampoo strip color faster than almost anything else. If you're still using a drugstore formula on color-treated hair, this is the first thing to change.
Consider a UV protection product for your hair.
Yes, these exist. UV-filtering hair products — whether in a leave-in, an oil, or a spray — do for your hair what you do for your skin. If you spend time outside, this is worth adding.
Rinse with cool or cold water.
The cuticle closes in cool water and opens in hot. Rinsing cool after every wash helps seal the cuticle, lock in moisture, and extend how long your color stays vibrant. It's a small habit with a disproportionate impact.
The product conversation worth having in the chair
The OI line from Davines is what we reach for most often when a client is heading into a high-damage season. It's rich, nourishing, and protective without being heavy — it's designed for hair that needs to look polished in conditions that are working against it. The oil in particular is one of the most versatile products we carry: frizz control, shine, heat protection, and color preservation all in one step.
If you're specifically concerned about color vibrancy between appointments — keeping your tone from going brassy or your color from looking washed out in summer photos — that's a more specific conversation.
The honest version of all of this: the right answer depends on your hair. What you're working with, what services you've had, what your summer actually looks like. We don't make one-size-fits-all product recommendations because hair doesn't work that way.
Bring these questions to your next appointment. We'll take a look at where your hair is and tell you exactly what we'd do.
The short version, if you're skimming
Summer is harder on color-treated hair than any other season. The combination of UV exposure, humidity, heat styling, and more frequent washing adds up faster than expected — and most of it starts before you notice.
The clients who come in before summer and build even a basic protective routine at home are the ones who love their hair in August, not just in May.
If you're overdue for an appointment or heading into an event season with a lot going on, now is a good time to get on the books.
