After Your Additional Color (Added in Foil): 48-Hour Do's & Don'ts (Additional Color aftercare)
By Star Vibes Organic Salon | October 22, 2026
If you left thinking your highlights were “perfect, ” this is how you keep them that way. The single most important rule for Additional Color aftercare is simple: wait a full 48 hours before you shampoo. That pause helps your tone settle so your added depth and dimension stays spot-on, not rushed into fading.
I do a lot of foil work here in Naperville, and this add-on is one of my favorites because it makes highlights look richer, not stripy. Additional Color (Added in Foil) is a $30 add-on that puts extra color into foiled sections for more depth and dimension. If you searched “hair color salon near me” or “hair styling near me” and landed here, this guide is for you. Save it, and use it like a checklist for the next two days.
Quick reality check: The first 48 hours matter more than most people think. If you protect the tone now, you usually get more time before you feel like you “need it redone.”
Your first 24 to 48 hours after foils: the rules that keep color spot-on
Right after an Additional Color (Added in Foil) service, I want you thinking about two things: no shampoo and no extra heat. That combo is what keeps your new dimension looking clean and even.
Do this
- Wait 48 hours before shampooing. If your scalp gets a little oily, that is normal.
- If you need to rinse, use cool to lukewarm water and skip scrubbing your scalp.
- Keep heat low for a day or two. If you have to blow-dry, use lower heat and keep the nozzle moving.
- Heading out along the Riverwalk? Bring a small UV hair spray and use it like sunscreen for your color.
Avoid this
- Heavy sweating for 48 hours. Hot yoga, long runs, sauna. Sweat and heat push fading faster.
- Tight hats that press hard on the hairline or crown. Friction is rough on fresh tone.
- Hot tools on day one if you can help it. That first blast of high heat tends to dull shine.
- Dry shampoo the same day if you can avoid it. A lot of formulas leave a film that makes blonde look flat.
Busy parent or Metra commuter? Keep it simple that first night: brush gently, loose braid or loose bun, and keep your hands out of it. The less friction you add, the longer your foils stay bright and blended.
Days 3 to 7: keep the shine and stop brassiness before it starts
People tell me they love their highlights because they look “radiant and shine.” That shine is not an accident. It is what happens when you protect the hair for the first week, especially if you have blonde pieces or lighter ribbons that can turn warm fast.
How to wash once the 48 hours are up
- Use sulfate-free, color-safe shampoo. Sulfates are a common reason foils fade early.
- Keep water lukewarm to cool. Hot water lifts the cuticle and can pull tone out faster.
- Condition mid-lengths and ends every wash. And if you feel dryness, add a leave-in on damp hair.
- In Naperville’s four-season weather, the cooler, drier months usually mean you need more moisture. Static and wind are real, especially around downtown and the Naper Settlement area.
Sun, festivals, and patio season tips
If you are outside for a downtown festival or a long Riverwalk outing, a portable UV hair spray helps. Wind can rough up the hair too, so I like a neutral scarf that does not rub aggressively. Think soft fabric, loose knot. It is low effort and it protects the top layer where your foils live.
My go-to routine for foil highlights aftercare: shampoo, bond support, purple (only when needed)
You do not need a shelf full of products to keep your dimension. You need the right types of products, used at the right frequency. If you have ever had a scalp that itched or burned after highlights elsewhere, you already know why gentle matters.
A simple 3-step evening routine
- If you worked out, rinse sweat with cool water and apply conditioner to ends only. Skip shampoo until your 48 hours are up.
- Once you are washing again, stick with color-safe shampoo and conditioner and do not over-lather.
- Add a weekly deep conditioner or a bond-maintenance treatment. This is what keeps hair feeling soft, not straw-like.
For blondes and anyone fighting warmth, purple shampoo can help reduce brassiness after foils. Use it as needed, not daily. Too much can make hair look dull or slightly violet, especially on porous ends.

Swimming, workouts, and hot tubs after highlights: real timing that saves your tone
Two things cause the fastest “why does my color look different already?” moment: sweat and water that is packed with chemicals or salt. If you are planning workouts, pool days, or a hot tub weekend, use these time frames.
Exercise after Additional Color (Added in Foil)
I generally recommend taking it easy for 48 hours. Light movement is fine. Try to avoid heavy sweating and high heat classes until day three.
Swimming and hot tubs after foil highlights
Avoid chlorinated pools, salt water, and hot tubs for 72 hours. If you cannot avoid it, wet your hair with clean water first and apply a leave-in conditioner as a barrier, then rinse as soon as you are done.
If you are in Lisle, Downers Grove, Woodridge, Aurora, or Bolingbrook and you need to grab product quickly before a trip, I can usually help with a quick pickup so you are not guessing in a random aisle.
If something feels “off, ” tell me early and we’ll fix it fast
I take a lot of pride in doing color that looks right and feels good. People come to me after bad experiences, including over-processed highlights, and I keep the focus on healthy hair and clean tone. And I also know real life happens. A last-minute event. A workout you forgot about. A surprise rainstorm in Downtown Naperville.
“I don't have to stress about what to do with my hair. He takes one look and knows what to do. He casts the vision, gives me an amazing haircut and guides me on what to do outside the salon to keep it looking good until next time.”

Reach out if you notice any of these
- Your tone looks too warm too quickly, especially in lighter pieces.
- Your hair suddenly feels dry or rough even with conditioner.
- You are unsure if you should book a toner or gloss touch-up based on what you are seeing at home.
Text or call and tell me what you are seeing in natural light. I would rather do a quick check-in than let you sit with hair you do not love.

FAQs: foil highlights aftercare and Additional Color (Added in Foil)
How long should I wait to wash my hair after Additional Color (Added in Foil)?
Wait 48 hours before shampooing. If you need to freshen up, do a cool-water rinse and keep your hands off the foiled areas as much as possible.
Can I exercise after getting Additional Color (Added in Foil)?
I suggest skipping heavy sweating for the first 48 hours. Light movement is fine, but try not to soak your scalp in sweat or add a bunch of heat right away.
When can I swim or go in a hot tub after foil highlights?
Give it 72 hours before pool, lake, ocean, or hot tub time. If you have to go sooner, wet your hair with clean water first, apply a leave-in conditioner as a barrier, and rinse right after.
Which shampoo and conditioner should I use after foils to prevent fading?
Look for sulfate-free and color-safe on both shampoo and conditioner. Keep your first few washes cool to lukewarm, and do not over-wash. If you are blonde and seeing warmth, add purple shampoo occasionally, not every day.
How soon should I book a toner or gloss follow-up after Additional Color (Added in Foil)?
If you love the tone, you can usually wait until you start seeing warmth or dullness creeping in. If you notice brassiness early, reach out sooner. I would rather do a quick tone refresh than let you live with a color that is not making you happy.
