Grey roots are one of the most common hair concerns we hear about at Biro Hair Studio. Whether you colour your hair to cover grey, enhance your natural shade, or maintain a specific look, keeping your roots fresh is an ongoing commitment. But the right approach makes all the difference between roots that look grown-out and roots that look effortlessly maintained.
This guide covers everything you need to know about root touch-ups in Toronto — how they work, how often you need them, what to look for in a colourist, and what to expect from your appointment at our North York studio.
What Is a Root Touch-Up?
A root touch-up is a targeted colour service that applies fresh colour to the new hair growth at your roots, blending it seamlessly with your existing colour. Unlike a full colour service, a root touch-up focuses only on the regrowth area rather than the entire length of your hair.
Root touch-ups are most commonly used for:
- Covering grey or white regrowth
- Refreshing a single process colour at the roots
- Maintaining the look of a freshly coloured style between full colour appointments
- Blending natural root growth with highlights or balayage
How Often Do You Need a Root Touch-Up?
This depends on how fast your hair grows, how visible your roots are, and how much contrast there is between your natural colour and your coloured hair.
As a general guide:
Every 4 to 6 weeks — recommended if you have significant grey coverage needs or a high-contrast colour like dark roots with blonde lengths
Every 6 to 8 weeks — suitable for most single-process colour clients with moderate regrowth
Every 8 to 12 weeks — possible if your natural colour is close to your coloured shade or if you are embracing a more grown-out aesthetic
At Biro Hair Studio, we assess your specific colour situation during your consultation and give you a personalised maintenance schedule that works for your lifestyle and budget.
Grey Hair Coverage: What Are Your Options?
Not all grey coverage is the same. Depending on the percentage of grey in your hair, your natural base colour, and the result you want, your colourist may recommend different approaches.
Full Coverage Permanent Colour
For clients with high percentages of grey, permanent colour delivers the most complete and longest-lasting coverage. It penetrates the hair shaft fully and does not wash out between appointments.
Demi-Permanent Colour
For clients with lower percentages of grey or those who prefer a softer, more blended result, demi-permanent colour offers coverage with a more natural finish. It fades gradually over time rather than growing out sharply, which can look more natural between touch-up appointments.
Toning and Glossing
For clients whose grey has been incorporated intentionally into their look — silver, platinum, or salt-and-pepper styles — a toning or glossing service keeps the colour vibrant and the hair shiny without full coverage.
Highlights and Balayage to Blend Grey
Some clients prefer to blend their grey naturally rather than cover it completely. Strategic highlights or balayage can soften the line between grey roots and coloured lengths, extending the time between full touch-up appointments while keeping the look intentional and polished.
During your consultation at Biro Hair Studio, Abir will review your hair, your lifestyle, and your colour goals to recommend the right approach for you.
What Happens During a Root Touch-Up at Biro Hair Studio?
Consultation
Every colour appointment at Biro begins with a consultation. We look at your current colour, assess your regrowth, discuss any changes you want to make, and confirm the formula that will deliver the right result.
If you are a new client, please come in with your hair in its natural state — no heavy styling products — so we can accurately assess your root colour and hair condition.
Formula Preparation
We prepare a custom colour formula matched to your existing colour or adjusted based on the look you want to achieve. We use professional, high-quality colour products that are gentle on the hair and scalp.
Application
Colour is applied to the root area only, carefully worked to the line where your existing colour begins. The application is precise — we do not want colour overlap on previously coloured hair, which can cause damage and uneven tone over time.
Processing
Your colour processes for the time needed to achieve full coverage. We monitor throughout to ensure even, consistent results.
Rinse and Treatment
After rinsing, we apply a conditioning treatment to close the cuticle and restore shine. Colour services can leave the hair slightly porous, and the right aftercare immediately after the service makes a significant difference to the longevity and vibrancy of your result.
Blow Dry and Styling
We finish with a professional blow dry and styling so you leave the salon looking and feeling great.
How to Make Your Root Touch-Up Last Longer
Getting the most out of your colour appointment is about what you do between visits. Here are our top recommendations:
Use a colour-safe shampoo
Sulphate-free shampoos are gentler on colour and extend the life of your root touch-up significantly. Avoid clarifying shampoos between colour appointments as they are designed to strip buildup and will fade your colour faster.
Wash your hair less frequently
Frequent washing is one of the fastest ways to fade colour. If you can extend your wash days using dry shampoo or a shower cap, your colour will last noticeably longer.
Use cool water when rinsing
Hot water opens the hair cuticle and allows colour molecules to escape. Rinsing with cool or lukewarm water after washing helps seal the cuticle and keep colour locked in.
Protect your hair from UV exposure
Sun exposure fades hair colour, particularly lighter shades. If you spend a lot of time outdoors, use a UV-protective hair product or wear a hat on particularly sunny days.
Avoid heat styling without protection
Always use a heat protectant before blow drying, flat ironing, or curling. High heat accelerates colour fade and damages the hair structure over time.
Frequently Asked Questions About Root Touch-Up in Toronto
How long does a root touch-up take?
Most root touch-up appointments take between 60 and 90 minutes including application, processing, rinse, and blow dry. If you are combining a touch-up with other services like a cut or treatment, allow additional time.
Will a root touch-up damage my hair?
When done correctly by a trained colourist using professional products, root touch-up services are safe for the hair. The key is avoiding colour overlap on previously coloured hair, which is why precision application and consultation matter.
Can I do a root touch-up at home?
Box dye touch-ups are possible but carry risks including uneven coverage, colour mismatch, and potential damage from incorrect processing times. A professional colourist matches your existing colour precisely and applies the formula with the technique and timing needed for a consistent result.
How much does a root touch-up cost in Toronto?
Pricing depends on hair length, the amount of regrowth, and whether additional services are included. At Biro Hair Studio, we are transparent about pricing during your consultation. Visit our price list at birohairstudio.com/price-list for current pricing.
I have never coloured my hair before. Can I start with a root touch-up?
If you want to begin covering grey for the first time, we recommend starting with a full colour service rather than a touch-up. This ensures even, consistent coverage from root to tip. After your first full colour appointment, maintenance touch-ups will cover just the regrowth.
