Semi-Permanent Colour

From £37

60 mins

Semi-permanent colour is the perfect option if you want to refresh your shade, boost shine, or experiment with a new tone without the long-term commitment of permanent colour. This ammonia-free treatment coats the hair rather than penetrating deeply, so it's gentler on your hair and gradually fades over a few weeks instead of showing a harsh regrowth line. Whether you're looking to gloss over dull colour, add a pop of fashion colour, or simply see more shine when you catch your reflection, semi-permanent is a brilliantly flexible choice.

What to Expect at Your Appointment

Your stylist will start with a quick consultation to choose the perfect tone for your hair and lifestyle. The colour is then applied to clean, dry (or slightly damp) hair, sectioned carefully for even coverage. After processing for around 20–30 minutes, we'll rinse thoroughly and finish with a nourishing conditioner. The whole appointment typically takes about 60 minutes, and you'll leave with glossy, vibrant colour that catches the light beautifully.

Who Is Semi-Permanent Colour For?

Semi-permanent is ideal if you:

Want to refresh faded colour between permanent services
Fancy trying a new shade or fashion tone without the long-term commitment
Have early greys you'd like to soften or blend (though it won't give full coverage like permanent colour)
Love the idea of colour that fades gradually rather than leaving a hard line as it grows out
Want to add shine and richness to dull or lacklustre hair

For vivid or pastel shades, pre-lightening may be recommended—your stylist will talk you through this during your free 15-minute consultation if you're a new client.

How Long Does It Last?

Semi-permanent colour typically lasts 4–12 weeks or around 10–20 washes, depending on your hair's condition and how often you wash it. The colour fades gradually rather than growing out with a noticeable root, so maintenance is much more flexible. You might see some colour running off in the first few washes (especially with vivid tones), so keep a darker towel handy for the first day or two.

Looking After Your Colour

To keep your colour looking fresh for as long as possible:

Wash less often and use cool or lukewarm water (hot water opens the cuticle and lets colour escape faster)
Switch to a sulfate-free, colour-safe shampoo—we stock and use Keune products in the salon, and the team can recommend the best options for you
Use heat protection when styling, as high temperatures can accelerate fading
Avoid chlorine and prolonged sun exposure where possible, or protect your hair with a hat or UV spray

If you're keeping a vivid or fashion shade, you might want to book refresh appointments every few weeks to maintain the intensity. The stylists at Park Row—Janet, Lynzie, Beckie, Alicia, Jess, and Imogen—are always happy to work out a schedule that suits your look and lifestyle.

Frequently Asked Questions

How much does semi-permanent colour cost?

Semi-permanent colour at Park Row starts from £37. The final price may vary depending on hair length, thickness, and whether any additional services like pre-lightening are needed.

How long does a semi-permanent colour appointment take?

Most semi-permanent colour appointments take around 60 minutes, including consultation, application, processing, and rinsing. If pre-lightening is required for vivid shades, allow extra time.

Will semi-permanent colour cover my grey hair?

Semi-permanent colour can soften and blend early greys, but it won't provide full coverage like permanent or demi-permanent colour. If you have a high percentage of grey and want complete coverage, your stylist can recommend a better option.

How long does semi-permanent colour last?

Semi-permanent colour typically lasts 4–12 weeks or around 10–20 washes, depending on your hair condition, how often you wash, and the products you use. It fades gradually rather than growing out with a visible root line.

Can I get bright or vivid colours with semi-permanent dye?

Yes, but vivid or pastel shades show up best on pre-lightened (bleached) hair. If your hair is darker, you'll see more subtle tone and shine. Your stylist will discuss pre-lightening during your consultation if needed.

Is semi-permanent colour damaging to my hair?

Semi-permanent colour is generally very gentle because it's ammonia-free and doesn't use strong developers. It coats the hair rather than penetrating deeply, making it a low-damage option compared to permanent colour.

What's the difference between semi-permanent and permanent colour?

Semi-permanent colour coats the hair and fades gradually over several washes without altering your natural pigment. Permanent colour penetrates the hair shaft, changes the structure, and grows out rather than fading, offering longer-lasting results and full grey coverage.

How should I look after my semi-permanent colour at home?

Wash less often with cool or lukewarm water, use sulfate-free colour-safe shampoo, and apply heat protection before styling. Avoid chlorine and prolonged sun exposure to help your colour last longer.

Will the colour run or stain my towels?

You may see some colour runoff in the first few washes, especially with vivid tones. Use a darker towel for the first day or two and be cautious with light-coloured fabrics until the colour settles.

Do I need a patch test before semi-permanent colour?

If you have sensitive skin or a history of allergies, let your stylist know. They can arrange a patch test according to brand guidelines to ensure the product is safe for you.
