Grey Blending vs Full Head Highlights vs French Blending: What’s the Difference?
If you’re researching grey blending, full head highlights, or the new French blending hair technique, you might be wondering which service is best for your hair.
All three colouring techniques involve lightening the hair and adding dimension, but they are designed for very different results, maintenance levels, and hair goals.
In this post, I explain the difference between SeamlessBlend® grey blending, full head highlights, and the French blending method so you can choose the right service for your hair.
What Is SeamlessBlend® Grey Blending?
A SeamlessBlend is a modern, bespoke colouring technique designed to soften the appearance of grey hair rather than fully covering it, while blending any old artificial colour so your hair blends root to tip with no regrowth line.
Instead of applying a solid colour over the greys, I use a combination of super fine highlights and lowlights to break up the contrast between old artificial colour and natural grey strands. The result is a soft, natural-looking blend where greys become part of the overall colour.
This method is particularly popular with clients who want to transition into their natural grey gradually or reduce the need for frequent root colour appointments and achieve a hair colour that suits their natural complexion.
Benefits of Grey Blending
Softens the appearance of grey hair providing a modern, polished colour
Creates natural-looking dimension
Eliminates harsh regrowth lines and puts hair health first
Low maintenance
Helps clients transition to natural grey gracefully
No use of permanent colour
Grey blending is ideal if you want your colour to look modern, natural, and effortless rather than heavily coloured.
What Are Full Head Highlights?
A full head of highlights is one of the most well-known hair colouring techniques.
With this service, highlights are placed throughout the entire head of hair, from the hairline to the nape, usually using foils or other lightening techniques. The aim is to lift multiple sections of the hair to create an overall lighter and brighter result.
Compared with grey blending or French blending, full head highlights tend to produce a more noticeable colour transformation.
Benefits of Full Head Highlights
Creates a significantly lighter overall look
Adds brightness and contrast
Ideal for blonde transformations
Even distribution of highlights throughout the hair
Because the hair is lightened from the root, a full head of highlights usually requires regular maintenance appointments to keep the colour looking fresh, even against a grey root.
What Is the French Blending Hair Technique?
The French blending method is a modern colouring approach inspired by the effortlessly chic look often associated with Parisian hair and devised by a popular French colour house.
Instead of strong, obvious highlights, French blending focuses on delicate lightening, permanent and demi permanent foiling and tonal work to create a soft transition between colours, but it does not mimic grey pattern.
The result is hair that has subtle and elegant colour, with ‘softer grow out compared to blanket coverage’
Benefits of French Blending
Natural-looking colour
Soft dimension without harsh highlights
Lower maintenance grow-out compared to blanket permanent coverage
Elegant, understated finish
French blending is perfect for clients who want natural-looking artificial colour with lower maintenance compared to full permanent coverage.
Grey Blending vs Highlights vs French Blending:
Which Should You Choose?
Choosing the right colouring technique depends on your hair goals, natural colour, and preferred maintenance level.
You may prefer:
Seamless Grey Blending
Best for clients who want to soften greys while keeping a natural, low-maintenance look and eliminate harsh lines created by permanent colour.
Full Head Highlights
Ideal if you want a brighter, lighter colour transformation, particularly for blonde results and you are happy with regular maintenance and obvious regrowth.
French Blending
Perfect if you want to maintain an artificial subtle colour that will look soft, but you are happy with some maintenance as the grey pattern is not followed.
