How Long Highlights Take: The Main Factors

How long highlights take at a salon depends on several key factors. Understanding these helps you plan your appointment and set realistic expectations. At ARQ Hair, we guide clients through this process, and the timing varies significantly based on your specific needs.

The main variables that affect appointment length are:

• Hair length and thickness, longer, thicker hair takes more time to process

• Desired lightness level, going from dark to very blonde requires more processing time

• Current hair condition, damaged or previously coloured hair may need special care

• Number of highlights, full head versus partial coverage makes a major difference

• Your hair type, fine, curly, or textured hair processes differently

• Toner or gloss application, adding these steps extends your appointment

Most salon appointments for highlights range from 2 to 4 hours. Some clients finish in 90 minutes; others need 5 hours or more. The difference isn't random, it comes down to these specific factors working together.

Several key factors determine how long your highlights appointment will take at the salon.

How Long Do Half-Head Highlights Take

Half-head highlights typically take between 1.5 to 2.5 hours from start to finish. This service targets the upper portions of your hair, focusing on the face-framing sections and crown area where dimension shows most.

• A quicker appointment than full-head coverage

• Strategic lightening around your face for dimension

• Lower maintenance between touch-ups

• Subtle, blended colour rather than dramatic change

The actual processing time depends on how light you want to go. If you're moving from dark brown to a light blonde, the developer needs more time to lift the colour. Moving from a medium shade to a lighter shade typically takes less time.

Many clients prefer half-head highlights because they deliver noticeable results without the time commitment of a full head. The stylist places foils or uses a balayage technique to create natural-looking dimension. After the colour processes, your stylist rinses, applies treatment, and styles your hair.

How Long Do Full-Head Highlights Take

Full-head highlights take between 2.5 to 4 hours on average, though some appointments extend to 5 hours depending on your hair. This service covers your entire head, creating all-over lightness and dimension throughout.

Full-head highlights are ideal when you want:

• Complete colour transformation across your entire head

• Consistent lightness from roots to ends

• Maximum dimension and movement

• A bold new look rather than subtle changes

The time increases significantly with full coverage because your stylist must section your entire head and apply colour to every section. Finer hair processes faster than thick, coarse hair. Previously coloured hair may need pre-treatment, which adds time to your appointment.

Understanding hair colour science and processing shows that different hair types and conditions require different development times. Your stylist assesses your hair's porosity and texture during the consultation to estimate how long processing will take.

At ARQ Hair, we use Wella Colour expertise to customise the process for your hair. We assess your hair's condition and recommend the best approach. If your hair is damaged or sensitive, we may suggest gentler options or split the appointment across two visits.

What to Expect at a Highlights Appointment

Your highlights appointment begins with a consultation where your stylist discusses your goals and assesses your hair. This conversation typically takes 10 to 15 minutes but is crucial for getting the result you want.

During the consultation, your stylist will:

• Ask what look you're aiming for and show you reference photos

• Check your hair's current condition and previous colour history

• Discuss how often you're willing to maintain the highlights

• Explain the process and realistic timeline for your appointment

• Address any concerns about ammonia sensitivity or previous reactions

After the consultation, your stylist sections your hair and applies colour using foils, balayage, or another technique. This application phase takes 20 to 40 minutes depending on how many sections your hair needs.

Once colour is applied, the processing phase begins. Your stylist sets a timer based on your hair type and desired lightness. Most processing takes 20 to 45 minutes. Your stylist checks your hair periodically to ensure it's lifting evenly. Monitoring this chemical reaction closely remains the most effective method for preventing hair breakage while achieving the optimal level of lift.

When processing is complete, your stylist rinses the colour out thoroughly. Rinsing and conditioning takes 10 to 15 minutes. Many salons apply a treatment mask during this time to restore moisture and protect your hair.

Finally, your stylist blow-dries and styles your hair. This finishing stage takes 15 to 25 minutes and shows off your new highlights properly.

Hair Highlights and Toner Appointment: Adding Extra Time

Adding toner or a gloss to your highlights appointment extends your total time by 20 to 40 minutes. Many clients choose this option to refine their colour and add shine.

Toner neutralises unwanted brass or yellow tones that appear as hair lightens. A gloss adds shine and subtle colour dimension. Both services happen after your highlights are complete and rinsed.

If you're adding toner or gloss, your stylist:

• Applies the toner or gloss product to your lightened hair

• Lets it process for 10 to 20 minutes

• Rinses and conditions your hair again

• Blow-dries and styles

Salon guidance on toner and gloss techniques explains that toner is essential after lifting dark hair to very light shades. Without toner, your highlights may appear brassy or yellow, especially in natural light.

For clients in the Fulham area seeking expert balayage and highlights, we recommend discussing toner during your consultation. If you're unsure whether you need it, your stylist can assess your hair after the highlights process and recommend it then.

The extra time is worth it if you want polished, salon-quality results that last longer between appointments. Toned highlights can fade more gradually than untoned ones, which can help your colour stay fresher.

Tips for Optimising Your Salon Visit

Plan your appointment strategically to make the most of your time and get the best results.

Arrive 5 to 10 minutes early. This gives you time to settle in and have a proper consultation without feeling rushed. Rushing through the consultation often leads to miscommunication about what you actually want.

Bring reference photos of highlights you like. Show your stylist exactly what appeals to you, the placement, the shade, the dimension. Photos eliminate guesswork and help your stylist understand your vision clearly.

Discuss your lifestyle and maintenance commitment. If you travel frequently or prefer low-maintenance hair, tell your stylist. They can suggest highlight placement and techniques that work with your routine.

Ask about the products your salon uses. At ARQ Hair, we use premium brands like Wella, Nioxin, and Sebastian to ensure healthy, vibrant colour. Knowing your salon's product line helps you maintain your highlights at home.

Book your appointment on a day when you're not rushed. Highlights appointments require time, and feeling pressured affects the whole experience. Choose a time when you can relax and enjoy the process.

If you have ammonia sensitivity or previous reactions to colour, mention this before your appointment. Learn about ammonia-free options and gentle alternatives that work for sensitive scalps.

Check how often you need touch-ups. Most highlights need refreshing every 6 to 8 weeks, though this varies based on how fast your hair grows and how visible your roots become. Discover the best maintenance schedule for your highlights.

Frequently Asked Questions

How long do highlights take at a salon?

Highlights typically take between 2 to 4 hours at a salon, depending on your hair length, thickness, and the technique used. Half-head highlights usually take 1.5 to 2.5 hours, whilst full-head highlights can take 3 to 4 hours. If you're adding toner or a gloss, allow an extra 30 to 45 minutes. The complexity of your desired result and your hair's current condition also influence the total time.

Does hair length affect how long highlights take?

Yes, hair length significantly impacts appointment duration. Shorter hair (shoulder-length or above) typically requires 1.5 to 2 hours for full-head highlights, whilst longer hair (past shoulder-length) can take 3 to 4 hours or more. Thicker or denser hair also takes longer because the colourist must work through more hair to ensure even coverage and colour saturation throughout.

What's the difference between how long foil highlights and balayage take?

Foil highlights generally take longer than balayage because each section is carefully wrapped in foil to isolate the colour. Foil highlights typically take 2.5 to 4 hours, whilst balayage (hand-painted highlights) usually takes 1.5 to 3 hours. However, balayage's duration depends on how many highlights you want and the complexity of the placement. Both techniques benefit from professional expertise to achieve the best results.

Should I allow extra time if I'm getting highlights and a toner in the same appointment?

Yes, plan for an additional 30 to 45 minutes if you're adding toner after your highlights. Toner refines the colour tone and ensures a polished finish, which is especially important if you're going for a specific shade. If you're also having a haircut, add another 20 to 30 minutes. Discuss the full timeline with your colourist during your consultation so you can book the appropriate appointment length.

Understanding how long highlights take helps you plan your appointment and feel prepared. Whether you're choosing half-head or full-head coverage, adding toner, or scheduling your first highlights, the key is finding a salon that listens to your goals and takes the time to do it right. At ARQ Hair, we combine Wella Colour expertise with personalised service to deliver highlights that enhance your natural beauty and fit your lifestyle.
