How long should I wait to wash my hair after dyeing?

When it comes to dyed hair, it can be tricky to know how to go about maintaining it, especially if you’re a first time dyer. How long should you wait to wash your hair afterwards? Are you safe to use the same hair care products as before? Should you use conditioner more often? That’s why today I’m going to attempt to answer some of these burgeoning questions, discussing how best to treat your hair once it’s been coloured. 

How to wash dyed hair without losing its colour

When it comes to dyed hair, ideally you should avoid washing it for at least 72 hours after your treatment. This is because the process of dyeing involves lifting your hair cuticle (the protective layer that defends your hair shaft) and this can take up to three days to close again, sealing the new colour molecules and ensuring that the longevity of your new do.

However, after this period things can become tricky – are you okay to settle back into your old routine of washing your hair every day or do you need to adapt a new approach? Well, as Sam from our Stewarton store discusses in her blog, ‘How do I keep my dyed hair from fading?’ water and dyed hair don’t necessarily always get along.

This is because, if you wash your hair too much, the water can cause the colour of your dye to fade. Plus, that’s not to mention the fact that over-shampooing your hair with harsh chemical products can deprive it of essentials oils, risking dryness and dandruff. You may need to reconsider your routine and the hair care products you used to use.

Try to avoid shampoos and conditioners that contain harsh ingredients like alcohol, parabens and SLS and instead try to incorporate more natural products into your routine that are safe for colour treated hair. John Masters’ Organic Lavender Shampoo might be a good choice here as it is infused with nourishing, plant-based ingredients such as aloe vera, rosemary and chamomile oils, helping to strengthen and protect your hair.

Should you wash dyed hair with hot or cold water?

Okay, so you’ve looked at your routine, incorporated more nourishing hair care products and even reduced the amount of times you wash your hair each week. So far, so good but when you do turn to a shower, should you be opting for hot water or cold water?

This might sound like a silly question – after all, not many of us want to brave a cold shower! However, hot water may actually reduce the longevity of your hair dye because, unlike cold water which helps to seal your hair cuticles, hot water can open them! Not only does this make your hair more vulnerable to potential damage, it can also cause the colour of your dye to fade – not so good!

Now I’m not about to suggest that you try and stomach an icy cold shower each week – no matter how good this might be for your dyed hair, it’s definitely not doing your body many favours. Instead, I’ll ask for compromise. Instead of stepping into a steamy shower try to dial the temperature down until it’s lukewarm – not too hot but just cool enough to bear.

Can I condition my hair after colouring?

You’ve just about mastered shampooing and washing your hair but what about conditioner? As I mentioned earlier, over-shampooing your hair can be a real issue which is why I sometimes recommend reducing the amount of shampoo you use. Conditioner, on the other hand, is different as your dyed hair will be crying out for moisture and nutrients at this time.

Similar to shampoo though, the type of product you use really matters. That’s why, as a follow up to their Organic Lavender Shampoo, I’d recommend using John Masters’ Hibiscus and Honey Organic Hair Reconstructor. As the name may suggest, this conditioner is dedicated to renewing and repairing dry, damaged hair and it contains plenty of soy and whey amino acids too. It’s also completely safe for colour treated hair and can help to improve your hair’s natural vitality!

However, once a week you might want to take this a little bit further by using an intense, leave-in conditioner to help treat your hair. This can help those crucial nutrients to penetrate that bit deeper into your hair, helping to tame frizz and manage any dryness. In these instances, Giovanni’s Ultra Sleek Conditioner and Styling Elixir might be your best option!
