How to Keep Dyed Hair Healthy: Tips and Expert Advice

Can dyed hair be healthy? Caring for colour-treated, dyed or bleached or highlighted hair is a constant topic of conversation here at Ogario London HQ. At least 50% of our team have colour-treated hair and, as we have dyed, coloured and highlighted many heads of hair in our salon, we can answer that question with a big emphatic, YES. Yes, dyed or coloured hair can be healthy. It’s just a question of how you treat it. With years of experience in helping clients to maintain colour-treated, highlighted or bleached hair we’ve put together our tips on how to keep your dyed hair healthy.

How to Keep Dyed Hair Healthy

Whether you’ve had dyed hair for more years than you can remember or you are about to embark on the exciting world of vibrant colour, its never too soon or too late to think about protecting your investment. Thinking about your colour-treated hair as an investment is a great place to start. You’ve spent time and money on your hair and, of course, you want it to look as good as possible for as long as possible.

Take good care of your hair and colour treatments can last longer. Your hair can look more vibrant, healthy and shiny.

Here’s what you need to know…

1.  Choose a gentle shampoo.

A moisturising shampoo is good too. The reason for this is that when the hair has been dyed or coloured, the chemicals penetrate the outer layer of the hair. This is so that the inner layer of the hair can absorb the colour. Once the chemical process has taken place the hair is, to put it in very blunt terms, damaged. This leaves hair prone to becoming dry.  You can read more about what it means if the cuticle is broken in our blog on split ends. But essentially, what we recommend is that you use a gentle, moisturising shampoo.

2. Prepare for your colour appointment with at-home conditioning.

The best way of achieving long-lasting colour results is by having a great foundation to start with. By getting hair in the best shape possible, which means as hydrated as possible, it can hold onto colour pigments more effectively. So, as with your shampoo use a conditioner with high levels of moisturising ingredients before your appointment to give hair the best chance of absorbing the colour.

Here are a couple of our favourite moisture-boosting ingredients below:

      • Tamarind adds moisture to hair in our Hydrate and Shine Conditioner; helping to maintain colour treatments and improve the texture of dry hair
      • Marshmallow (the herb!) is another favourite ingredient in Hydrate and Shine Conditioner as it softens and smooths hair to help it retain moisture.

3. Condition dyed and coloured hair to keep it healthy.

Once you’ve left the salon, swinging your freshly coloured tresses, make it your mission to condition your dyed hair. Aftercare is essential for maintaining colour. Condition every time you wash your hair. Never skip. If your conditioner is not working for you. Find one that does.

4. Gently squeeze the water out of your hair before you apply conditioner.

After shampooing and rinsing your hair, use a small towel and gently squeeze out the excess water from the hair. This is one of the best things you can do for your hair in preparation for conditioner. If you leave in excess water, you can watch your conditioner slide down the plughole as it slips out of your hair. By towelling out the water the conditioner stays on the hair so that you get more from your product.

5. Avoid washing hair in really hot water.

Heat, whether it’s from the sun, the hairdryer or your hot water tap, is damaging for hair. That makes heat one of the biggest culprits for drying out hair. You can’t avoid all heat but you can wash hair in a tepid temperature to help reduce heat damage.

6. Give your hair a break.

Where once your hair might have been more forgiving, dyed hair can become dry and damaged with excessive heat.

We recommend:

      • Try air-drying your hair at least once a week.
      • Turn down the heat on the hairdryer. If you are rough-drying your hair before styling it can be done with a cooler temperature.
      • Reduce drying time. Most of us are more likely to over-dry hair than not! Drying your hair probably takes less time than you think. Try reducing the amount of time you dry your hair for by 1-minute each time you dry.

In our experience, we think most people can reduce the time that hairdryer heat is applied to the hair and get better results.

7. Choose the right Styling Product.

Think about giving your hair protection and added moisture as you style. Choose multitasking products that work as a leave-in conditioner as well as a styling product.

We recommend:

      • Choose styling products that will hydrate your hair. Because ingredients such as alcohol denat and silicones can be drying for the hair we prefer to avoid them.
      • Our Styling Mist for Natural Hold and a Glossy Finish is a favourite with our clients who have dyed or coloured hair. They love it because it gives an extra moisture boost to the hair, making it easier to style and it gives heat protection.

8. Use a hair mask treatment once a week, every week.

An intensive conditioner will help replenish everything the colour-treatment took away from your hair. So, if you do this once a week,  and you will be amazed at how long your colour lasts. Plus your hair will be easier to style and manage. Think you don’t have time? Think again! Check out our blog for ideas on how to make time for your weekly hair mask.

      • As well as using a weekly hair mask before colouring, use one regularly afterwards to keep hair hydrated so it holds on to colour for longer.
      • Apply a treatment hair mask once a week for three weeks prior to your colour appointment. This will help to repair any damage, infuse the hair shaft with moisture and help seal the cuticle. The smoother the cuticle, the more hair colour pigment can cling on and stay put.

Change your Hair Colour, Change your Approach

So, you may be reading this and thinking about dyeing your hair for the first time. Colouring or highlighting your hair for the first time is a big step. Whether you are making a radical change or enhancing your natural colour, it’s exciting. But it’s also a big commitment. You have to give a lot more thought about caring for colour-treated hair. There are roots to consider, dry ends to manage, over-lapping colour to avoid and different hair texture to manage. When you colour your hair you really do have to adopt a different mindset in how you take care of your hair. This may sound daunting but keep it simple. Follow our tips above and just in case you have any more questions, we’ve covered some of the ones that might crop up, below.

My hair is Dry, Brittle Hair after Colouring.

When hair becomes dry and brittle it’s been through too much. You may even be experiencing some breakage. It’s time to take a breather and reflect. Of course, you can overdo it with colour treatments. Hair dyes are strong chemicals and if you overlap the colour treatments too often they cause the hair to become brittle and, worse case, break. There may be other factors. If you are using heated styling tools on dyed hair or if you are not adding sufficient moisture, the combined effect can really take its toll on hair. Once you’ve got to the point of hair becoming brittle, it’s time to reduce the heat as much a possible and get into a routine of regular, weekly deep conditioning treatments. Follow our tips above and take a look at our blog on how to fix damaged hair for further advice.

Hair elasticity is a term that you may have come across. Its’s basically the opposite of damaged or broken hair. When hair has elasticity it has stretch simply because it has the moisture that it needs. We’ve written a blog all about how you can improve hair elasticity. Find out how you can improve the elasticity of your hair.

What’s the best treatment or deep conditioner for colour-treated or bleached hair?

The best treatment or deep conditioner for colour-treated or bleached hair is one that can really get moisture to the core of the hair. Our preference is for water-based deep conditioners. Argan oil is great for smoothing and nourishing the hair but when you really want to get to the heart of the problem, pro vitamin b5 is our go-to for deep conditioning. Plant-based pro vitamin b5 is proven to penetrate the cuticle and add moisture right to the core of the hair. So it puts back the moisture that hair dye takes away. It’s the absolute foundation of our hair care formulations and our Restore and Shine Hair Masque, awarded Best Hair Mask in the Beauty Bible Awards, is a treatment or deep conditioner that replenishes colour-treated or bleached hair.

How do you keep your hair healthy after dying it?

Keeping hair healthy after dying it is really just a question of following the simple steps we’ve outlined above. We’ve summarised some of the key points below.

  1. Choose a gentle, moisturising shampoo.
  2. Always condition the hair after shampoo
  3. Gently squeeze excess water out of the hair before you apply conditioner.
  4. Give your hair a break from the heat to help keep dyed hair healthy.
  5. Choose moisture-boosting styling products.

What’s the best hair repair treatment for damaged hair?

Restore and Shine Hair Masque is a treatment developed to bring damaged hair back to it’s lustrous best. But remember, treating damaged hair is a journey, not a one-off event. We recommend getting into a good weekly routine of treatments. Hair like your skin likes regular attention so keep adding moisture. Little and often works best for repairing damaged hair and keeping dyed hair healthy.

How to take care of Dyed Hair

If you’ve invested time and money in a colour-treatment it makes sense to protect your investment. Hopefully, we’ve been able to persuade you that changing the way you approach your hair is not that big a deal, it really is just about building a routine and making some small changes.  Those small changes can make a big difference in keeping your dyed hair healthy.
