What rainbow hair colour is best for me?
If you’re trying to figure out which rainbow hair colour will suit you best, there are a few things to consider. Credit: @laurlahair
1. It probably isn’t going to happen in one sitting
In order to get the most vibrant rainbow hue, the hair often needs to be bleached first – sometimes multiple times over if your hair is naturally dark. It’s best to have a consultation with your colourist beforehand to talk through the process and what they think will be possible to achieve in one appointment so that you go in with realistic expectations.
2. The upkeep is no joke
Maintaining rainbow hair takes a lot of commitment, so if you’re a wash-and-go kind of girl be prepared to have to spend more time caring for your hair to keep it in the best condition. Some styles (like ombre or peekaboo highlights) won’t require as frequent touch-ups as allover hues, so this is something to bear in mind.
3. It can be pricy
It’s expensive to maintain rainbow hair, so before you commit consider how often you can feasibly afford to go to the salon.
4. The growing out stage can be difficult
You may need to redye all of your hair to cover up the colour or wait until your natural shade has grown out, which could take months or even years (depending on the length).
How to get rainbow hair
With coloured hair becoming more a trend, there are more and more at-home DIY hair dye kits available. These are great if you’re looking to add rainbow tips to your hair or want to try out a fun semi-permanent look but if you’re looking to rock the hue more permanently we would advise you to go to a salon.

Not all hairstylists will be trained or confident in creating such creative coloured looks, so we recommend doing your research and looking on Instagram to find a salon that specialises in coloured hair.
A patch test will usually be required at least 48 hours before your appointment to check you’re not allergic to the dye. It’s important to note that even if you’ve dyed your hair in the past, the ingredients in different colours and brands of dyes vary, so just because you haven’t had a reaction in the past doesn’t necessarily mean you won’t next time.
Rainbow hair colour tips and maintenance
Rainbow hair calls for extra special care to keep it looking vibrant. Here are our tips for making your colour last longer:
Limit heat styling
Colour-treated hair is more fragile than unprocessed hair, so you should be more conscious about blowdrying, curling and straightening your hair and try to limit the use of heat as much as you can.
When you do use heated styling tools, remember to always use a heat protectant spray like the VO5 Heat Protect Spray to protect your strands and keep damage to a minimum.
Avoid washing your hair too often
Overwashing coloured hair can lead to dryness and colour fade, so if you’re used to washing your hair every day, try spacing it out to every 3 or 4 days instead. Using dry shampoo is a great way to tide you over on non-wash days and keep your hair fresh and grease-free.
Use colour-friendly hair care
While your regular shampoo might do a great job at cleansing your hair, some can be too stripping for coloured hair which can lead to your colour fading faster. Try switching your usual products out for the TRESemmé Colour Shineplex Shampoo and Conditioner, which are sulphate-free and work to maintain vibrancy and shine for up to 12 weeks.
Deep condition make regularly
Coloured hair is more vulnerable to damage and breakage, so make sure to treat your hair to a nourishing mask, like the TONI&GUY Damage Repair Mask as part of your weekly hair routine.
Stay out of direct sunlight
The sun is one of the worst causes of colour fade and can leave your hair looking dull and your colour flat and lacking shine. To tackle this, wear a sunhat during the day (especially when the sun is at its strongest) to stop your rainbow hair from lightening.
Avoid swimming pools
You’ve probably heard of blonde hair turning green from swimming pools, but it’s not just blondes who are at risk. Chlorinated water can cause your colour to fade prematurely, as well as drying it out and making it frizzy.
If you don’t want to wear a swim cap, rinse your hair in the shower with water before getting into the pool to stop it from soaking up as much chlorine. You can also apply a leave-in conditioner to act as a barrier between your hair and the chlorine.
