One of the most common questions clients ask before booking a color appointment is, “How long will this last?” The honest answer is that it depends entirely on the type of color used, your hair’s condition, and how you take care of it afterward.
This guide breaks down how long each type of salon color lasts, what causes it to fade, and what you can do to make it last longer. Whether you’re deciding between services or just trying to figure out when to rebook, this will give you clear timelines for every option.
The Short Answer
Permanent color lasts until it grows out, typically requiring a root touch-up every 4 to 6 weeks. Demi-permanent color fades gradually over 4 to 6 weeks (roughly 24 to 28 washes). Semi-permanent color lasts 4 to 12 washes. Balayage and highlights don’t “fade” the same way because they involve lightening, but they need refreshing every 6 to 16 weeks, depending on the technique. The type of color your stylist recommends depends on your goals, your gray coverage needs, and how much maintenance you want.
Permanent Hair Color: 4 to 8 Weeks
Permanent color is what most people think of when they think of “getting their hair colored.” It opens the hair cuticle, deposits pigment inside the strand, and permanently changes your hair’s color.
How long it lasts: The color itself is permanent, meaning it doesn’t wash out. However, the roots grow in every 2 to 4 weeks, and the visible contrast between your natural color and the dyed hair is what drives the touch-up timeline. Most clients schedule a single-process touch-up every 4 to 6 weeks.
The mid-lengths and ends can fade over time, though. Permanent color gradually loses vibrancy due to washing, sun exposure, and heat styling. After 6 to 8 weeks, the tone may look duller or warmer than when it was first applied.
Best for: Full gray coverage, going darker, significant shade changes, or anyone who wants consistent, long-lasting color.
What Numi uses: We use INOA ammonia-free permanent color for most single-process services. INOA’s oil-based delivery system creates permanent results with better shine retention and less damage than traditional ammonia-based formulas. For more on how this works, see our guide to ammonia-free hair color.
Demi-Permanent Color: 4 to 6 Weeks
Demi-permanent color sits between permanent and semi-permanent. It uses a low-volume developer to deposit color slightly deeper into the hair shaft than semi-permanent, but it doesn’t permanently alter the strand. It fades gradually with each wash.
How long it lasts: Roughly 24 to 28 washes, which translates to about 4 to 6 weeks for most people. It fades evenly and naturally, without the harsh line of demarcation that permanent color creates at the roots.
Best for: Blending early gray (up to about 50%), refreshing existing color, adding richness or depth without a permanent commitment, or toning down brassiness between full color appointments.
Why your colorist might recommend it: Demi-permanent color is gentler on the hair and produces a more natural, translucent finish. If you’re not ready for the maintenance commitment of permanent color, or you want to experiment with a new shade without long-term consequences, demi-permanent is a smart middle ground.
Semi-Permanent Color: 1 to 3 Weeks
Semi-permanent color coats the outside of the hair strand without opening the cuticle. It doesn’t contain ammonia or peroxide, which makes it the gentlest option available, but it also means the color fades the fastest.
How long it lasts: Roughly 4 to 12 washes, depending on the shade intensity and your hair’s porosity. Bold or dark shades tend to last longer than pastels or lighter tones. Most clients see noticeable fading within 1 to 3 weeks.
Best for: Experimenting with new shades, refreshing faded color between salon visits, or anyone who wants a completely commitment-free color change. Semi-permanent color cannot lighten hair; it can only add or refresh tone.
Glaze or Toner: 3 to 6 Weeks
A glaze treatment (sometimes called a toner or gloss) is a sheer, semi-permanent color that adds shine and refines your tone without changing your base color significantly. It’s one of the most underused services in the salon.
How long it lasts: Roughly 4 to 8 washes, or about 3 to 6 weeks. The fade is gradual and subtle.
Best for: Neutralizing brassiness in blonde or highlighted hair, adding shine to any color, refreshing tone between permanent color or balayage appointments, and smoothing the cuticle for a glossier finish. A glaze is also a great add-on after any color service to seal the cuticle and boost vibrancy.
Balayage: 3 to 4 Months
Balayage doesn’t “fade” the way all-over color does because it involves lightening the hair, not depositing a color that washes out. The lightened sections are permanent. What changes over time is the tone (which can shift warmer or brassier) and the grow-out at the roots.
How long it lasts: Most balayage clients come back for a refresh every 12 to 16 weeks (3 to 4 months). Some stretch it even longer. Because balayage is painted from the mid-lengths down with a soft root blend, there’s no harsh regrowth line, which is why it lasts so much longer than traditional color.
What fades: The toner applied over the lightened sections will fade over 4 to 6 weeks. When that happens, you might notice brassiness or warmth. A quick glaze refresh between full balayage appointments keeps the tone clean without a full color session.
Best for: Anyone who wants dimensional, natural-looking color with minimal maintenance. For more detail on this service, see our guide to how much balayage costs and our balayage vs. highlights comparison.
Highlights: 6 to 8 Weeks
Like balayage, highlights involve lightening, so the lightened strands themselves are permanent. The difference is that highlights are placed from root to tip using foils, which means the regrowth is more visible.
How long they last: Most highlight clients schedule a touch-up every 6 to 8 weeks. Root growth shows sooner with highlights than with balayage because the lightened pieces start right at the scalp.
Between appointments: A glaze or toner refresh at the 4 to 6 week mark can keep highlights looking bright and brassiness-free, allowing some clients to stretch their full highlight appointment to 10 to 12 weeks.
What Makes Hair Color Fade Faster?
Several everyday habits accelerate fading. Avoiding these will help you stretch the time between appointments:
Sulfate shampoos. Sulfates strip color from the hair. Switch to a sulfate-free, color-safe formula. We carry Kerastase and Oribe lines designed specifically for color-treated hair.
Washing too often. Every wash removes a small amount of pigment. Washing every 2 to 3 days instead of daily can add weeks to your color’s lifespan.
Hot water. Hot water opens the cuticle, which lets color escape. Rinse with lukewarm or cool water to help seal the cuticle and lock in pigment.
Heat styling without protection. Blow-dryers, flat irons, and curling irons all accelerate fading. Always use a heat protectant before styling.
Sun and chlorine. UV exposure and chlorinated pool water both strip color. Wear a hat or use a UV-protective hair product in summer, and wet your hair with clean water before swimming so it absorbs less chlorine.

Does permanent hair color really last forever?
The pigment deposited inside the strand is permanent, but the visible result changes over time. Roots grow every 2 to 4 weeks, and the color on the mid-lengths and ends gradually fades from washing, sun, and heat exposure. Most clients rebook every 4 to 6 weeks to maintain a consistent look.
How can I make my hair color last longer?
Use sulfate-free shampoo, wash every 2 to 3 days instead of daily, rinse with cool water, use a heat protectant, and schedule a glaze treatment between full color appointments to refresh your tone and add shine.
What's the longest-lasting color service?
Balayage lasts the longest between appointments because the lightened sections are permanent, and the soft root blend means there’s no visible regrowth line. Most balayage clients go 12 to 16 weeks between sessions. Book a consultation and we’ll help you decide which service fits your lifestyle.
Will demi-permanent color cover gray hair?
Demi-permanent color can blend gray by depositing a translucent layer of pigment over the gray strands, making them appear softer and less noticeable. It works best for clients with up to 50% gray. For 100% gray coverage, permanent color (like INOA) is the better option.
How often should I get a toner or glaze?
Every 4 to 6 weeks is typical, especially for blonde or highlighted hair that tends to shift warm or brassy between appointments. A glaze is quick (usually under an hour), affordable, and significantly extends the life of your base color or balayage.
