Full or Half Head of Colour
A full hair colour change can be as dramatic or as subtle as you wish. From platinum blondes to vibrant reds, chocolate browns to silver greys, we can transform your looks with a sensational full or half head of colour.
If you are not ready to fully commit to a permanent hair colour change, we can suggest various semi-permanent hair colour options as an alternative. Happily, these will wash out over time. They can also give you a great boost and get you ready for the next step... a full head of colour perhaps?
Highlights or Lowlights
Highlights or lowlights can brighten or darken your natural hair colour and add multiple tones and shades. Moreover, we can offer a multitude of colour choices from sun-kissed blondes, to vibrant redheads or chocolate-brown lowlights. If you're feeling daring, how about a pop of pastel pink or silver-grey highlights to add a unique edge to your natural hair colour?
Balayage or Ombré Hair Colour Techniques
Are you searching for a softer, natural-looking hair colour? If yes, balayage may be the look you're after! Balayage means 'to sweep' or 'paint’ in French. The technique involves painting or sweeping colour through your hair for a sun-kissed look. This is a great low-maintenance hair colour as your root regrowth will be less noticeable. Alternatively, another low-maintenance hair colour option is ombré. This is a more obvious two-tone hair colour with a defined line between the two colours.
Fashion Hair Colours
Dare to turn heads with a bold fashion colour from our Harpenden or Hertford salons! Embrace your inner mermaid with a vivid blue or purple colour or, for less of a commitment, try a pastel shade. Pastel hair colours are always on-trend and fade out gradually as you wash them. This allows you to try another when the mood takes you! We can even do subtle, peek-a-boo highlights and hidden colour panels which allow you to conceal or reveal your creative shades as you like.
Grey Blending
Embrace your greys with confidence with Johnson Blythe's expert Grey Blending service. Whether you want to make the most of your natural grey tones with a fashionable, seamlessly blended look or prefer complete grey coverage, our colour specialists will create a personalised result to suit you.
Using a combination of highlights, lowlights and glossing techniques, we subtly diffuse greys throughout the hair, softening regrowth and eliminating harsh lines. The result is a beautifully natural finish that allows greys to grow out more gracefully while maintaining a polished, modern appearance.

What makes Johnson Blythe one of the best hair colour salons in Hertford and Harpenden?
«At Johnson Blythe, we are well known for delivering expert hair colour services tailored to every client. Our experienced colour specialists stay at the forefront of the latest hair colouring trends and techniques, including balayage, highlights, root smudging, grey blending and colour correction.
Using premium L'Oréal Professionnel colour products, we create beautiful, bespoke results that enhance your natural features and suit your lifestyle. Whether you're looking for a subtle refresh, seamless grey coverage or a complete colour transformation, our Hertford and Harpenden salons offer professional advice, personalised consultations and exceptional colour expertise to help you achieve your perfect shade.
Do I need a consultation before my hair colour appointment?
«We always recommend that our clients pop in for a hair colour consultation to ensure that we achieve the best possible colour results for you. During the consultation, our colour experts in Hertford and Harpenden will assess your current hair, discuss your desired shade, and suggest the best colour options and colouring techniques. This personalised approach helps us deliver a hair colour that makes you look and feel fabulous.
Can you cover my grey hair?
«Definitely! Our hair colour specialists in Harpenden and Hertford are skilled in grey blending, offering stunning solutions that range from subtle touch-ups to complete hair colour transformations. Whether you prefer a natural colour that blends effortlessly with your natural locks or something more vibrant, our L’Oréal’s hair colour products provide long-lasting and beautiful results.
Do you offer semi-permanent hair colours?
«Yes! If you aren't keen on permanent hair colour, we offer a variety of semi-permanent colour options for clients who want a temporary change or are not yet ready to commit to a permanent shade. Our Semi-permanent colours fade over time and offer clients a fantastic way to experiment with different shades without long-term commitment.
How often will I need to refresh my hair colour?
«This depends on the type of colour service you choose. Root touch-ups for grey coverage are typically recommended every 4-6 weeks, while balayage and other low-maintenance colour techniques can often be refreshed every 3-6 months. During your consultation, we'll recommend a maintenance schedule tailored to your hair, lifestyle and budget.
Can I switch from dark hair to blonde?
«In most cases, yes. However, the process will depend on your current hair colour, previous colour history and the condition of your hair. Some transformations can be achieved in a single appointment, while others may require a gradual approach to maintain the health and integrity of your hair. We will advise you what to expect at your initial consultation.
What should I do before my hair colour appointment?
«We recommend arriving with clean, dry hair where possible and bringing along any inspiration photos you may have. If you're considering a significant colour change, a consultation beforehand will help us create the perfect personalised colour plan.
What are the differences between balayage and ombré?
«Balayage and ombré are both popular choices for our clients who are looking for a natural-looking, sun-kissed look. However, they are slightly different in terms of the end result. The balayage technique involves our colour technicians hand-painting lighter tones for a softer, sun-kissed effect that blends seamlessly with your natural hair colour. This makes regrowth less noticeable. Ombré, on the other hand, has a far more defined transition between the two shades, often giving a bolder, two dimensional look. Our hair colour experts in Hertford and Harpenden will help you to select a style that best suits your look and lifestyle.
Can you help me choose a hair colour that suits my skin tone?
«Absolutely. During your consultation, our colour specialists will assess your skin tone, eye colour, natural hair colour and personal style before recommending shades that will enhance your features and complement your complexion.
Why do I need a skin allergy test?
«Johnson Blythe Hertford and Harpenden are colour safe salons. For your safety and comfort, we require a quick allergy test at least 48 hours before your first colour service if you’re new to Johnson Blythe Hairdressing (or haven't been for a colour service in the past 6 months). This helps us to ensure there are no adverse reactions to the hair dye products, so you can enjoy your colour experience without any worries.

Will colouring my hair damage it?
«When carried out professionally, hair colouring should not compromise the health of your hair. We use high-quality L'Oréal Professional colour products and can recommend treatments such as Olaplex and professional conditioning services to help keep your hair strong, healthy and shiny.
How can I keep my hair colour looking fresh between appointments?
«Using professional colour-safe shampoos and conditioners, minimising heat styling and protecting your hair from excessive sun exposure can all help prolong your colour. Our stylists will recommend the best home-care products for your specific hair colour and condition. We stock a full range of L'Oreal Professional and Kerastase home care products in our salons.
Can you correct a hair colour that has gone wrong elsewhere?
«Yes. Our colour specialists have extensive experience in colour correction and can help resolve issues such as brassy tones, uneven colour, unwanted warmth, patchy highlights and box dye mishaps. We will assess your hair and create a bespoke plan to achieve your desired result.
