A guest sat in our chair last week for a lived-in color refresh, holding up her phone to the window light and frowning at a selfie she had taken in her bathroom that morning. In the photo her hair looked brassy, almost orange at the ends. In our studio mirror, under the 5000K daylight-balanced bulbs we installed at the color bar specifically to avoid this kind of confusion, the same hair read as warm honey blonde with soft caramel through the mid-lengths. She wanted to know which one was real. The honest answer is that both are real, and neither one is the whole picture.
This is one of the most common conversations we have at Eleven11 Hair Studio. Clients come in convinced their color has "gone wrong" because of what they saw in office fluorescents, in their car visor mirror, or in a sunny Rolling Meadows parking lot. Most of the time the color is doing exactly what it should. What changed is the light hitting it. Understanding why this happens will save you a panicked text to your stylist and a lot of second-guessing between appointments.
Why Hair Color Shifts Under Different Lights
Here is the thing we tell every guest at the color bar: hair color is not a fixed thing. It is a surface that reflects whatever wavelengths of light are hitting it, and different light sources emit very different mixes of wavelengths. Daylight is broad spectrum and balanced, so colors read close to their truest version. The warm incandescent bulbs in older homes push everything toward orange and gold. Cool LED bulbs strip out the warm tones and make hair look ashier, sometimes almost grey. Fluorescent office lights have green undertones, which is why almost everyone looks a little off in a cubicle.
When we formulate lived-in color at the salon, we are looking at your hair under color-balanced lighting that mimics daylight as closely as possible. We installed 5000K bulbs at the color bar (the same temperature photographers use for accurate color work) so the version of your color we are building matches what you will see in the most flattering and accurate conditions. The brassy version in your bathroom mirror is not a failure of the color. It is a bathroom bulb problem.
The Window Test We Use at the Studio
Before a client leaves the chair, we walk them to the front of the studio where natural light pours in from the windows. We do this on purpose. If the color reads beautifully in daylight, we know the formulation is right. If we only ever evaluated color under our color bar lights, we would be working in a bubble.
We encourage clients to do the same thing at home. When you want to check what your color is actually doing, step outside or stand by a window during the day. Hold your hair in your hand and look at it in indirect daylight, not direct sun (which can wash everything out and add temporary highlights from the angle). That is your real color. The orange tint under your bathroom vanity is the bulb, not your hair.
When the Shift Is Real (And When It Is the Light)
There are times when color genuinely is changing, and those are different conversations. Brassiness that shows up in daylight (not just under warm bulbs) usually means your toner has faded, your water at home is depositing minerals, or your shampoo is too clarifying for color-treated hair. Real warmth pulling through means the underlying pigment in your hair is showing more than we want it to, and we need a gloss appointment to refresh.
A few signs the shift is real and worth a call to the salon:
- The color looks different in daylight too, not just under indoor bulbs
- Your ends are noticeably warmer than your mid-lengths in every light
- Strands feel different (drier, more porous) along with the color shift
- You see banding or stripes that were not there when you left the salon
If you live in the Northwest suburbs and deal with hard water, mineral buildup can absolutely change how your color reads over time. That is a real shift, not a lighting trick, and it is worth bringing up at your next appointment.
What to Tell Your Stylist at the Consultation
When you book a color appointment, especially a complimentary consultation, bring photos taken in multiple lighting conditions. One in daylight, one in your bathroom, one in your car. This gives us a fuller picture of what you are seeing day-to-day, and it helps us formulate color that holds up across the lighting you actually live in.
We also ask clients about their home setup. If your bathroom has warm incandescent bulbs and you do most of your hair styling there, we will factor that in. We might go slightly cooler in the formulation so that when you see your hair under that warm bulb, it still reads balanced rather than overly golden. We think of good color as a relationship between the formulation, your hair's natural undertones, your maintenance routine, and the light you see it in. When all four are in sync, your hair looks intentional and beautiful across every setting.
Why This Matters More Than You Think
Clients who do not understand the lighting variable end up chasing their color. They see a photo they hate, they buy a purple shampoo to "fix" the brassiness, and they end up with hair that reads ashy and dull in daylight because they over-corrected based on what their bathroom bulb was showing them. Or they come in demanding a darker color because their hair "looks orange," when really their hair is exactly the tone we agreed on and the bulb is the culprit.
This is why we walk every guest to the window before they leave. It is why we ask about your home lighting during consultations. And it is why we encourage you to check your color in daylight before deciding it needs fixing. Most of the time, the color is doing its job. The light just needs adjusting.
Frequently Asked Questions
Why does my hair look orange in my bathroom but normal at the salon? Incandescent and warm LED bulbs emit a yellow-orange spectrum that exaggerates the warm tones in your hair. The color itself has not changed, the light is just pulling the warmth forward. Step outside in daylight and you will see the actual tone we formulated.
Should I take selfies in different lighting to send to my stylist? Yes, and we genuinely appreciate it. Photos in daylight, indoor bathroom light, and outdoor shade give us the clearest read on what your color is doing. One photo in one light source can be misleading for both you and us.
Can I change the bulbs in my bathroom to make my color look better? You can, and many clients do switch to daylight-balanced bulbs (around 5000K color temperature) for their main mirror. It will not change your hair, but it will give you a more accurate view of your color and make your makeup application easier too.
Why does my hair look completely different in office lighting? Fluorescent office bulbs often have a green undertone and a cooler spectrum, which can make blonde hair look ashier or duller than it really is. Brunettes can look flatter and less dimensional. This is universal and not specific to your color.
How do I know if my color actually needs to be refreshed or if it is just the lighting? Check your hair in indirect daylight near a window. If it still looks brassy, dull, or off in natural light, it is time for a gloss or toner refresh. If it only looks off under specific indoor bulbs, the color is fine and the bulb is the issue.
