Why does red hair colour fade so fast? Plus, secrets to keep it vibrant

Fiery, vibrant, dark or subtle, red hair is a real head turner! It's the high-impact hair colour that never goes out of style, but it’s also the toughest one to maintain. In this article, we explain the science behind this unique hue, plus share some secrets of making your red hair colour last longer.

At the end of this blog post, you will find a fun competition – join and get a chance to win one of the Smart Beauty permanent red hair dyes! 

Why does red hair colour fade quickly?

Before answering this question, it’s worth explaining the chemistry behind hair colouring process. When you apply a hair dye, colouring agents lift your hair cuticle. Once it's open, the dye molecules pass into the hair cortex, the layer responsible for your hair pigment. The colour gets locked there for up to 6 weeks until the dye molecules are washed away. 

Unlike other colours, red hair colour is made of very small molecules. Because of their size, they are more easily removed by water, especially when you use shampoo. Also, those small red colour molecules are more easily broken by UV, chemicals and harsh hair products.

How to keep red hair colour from fading fast?

There are a few essential rules to maintain vibrant and shiny red hair colour between colouring sessions. 

How to keep red hair from fading

 

Protect your hair from the sun

UV radiation is the main reason for colour fading. Therefore, you should use hair products that create a protective layer against it or wear a hat.

After having dyed your hair, don’t shampoo for 2-3 days

Wait for at least 72 hours so your hair cuticle can fully absorb the colour. Dry shampoo is your best friend!

Wash less, but with good hair products

Red hair molecules are so small, it’s very easy to wash them out. The less you wash your hair, the longer you keep the colour vibrant. Though when you do wash it, use sulfate-free shampoos and conditioners that are created specifically for colour protection.

Use hair colour refreshers

Every time you dye your hair, you weaken its cuticle. Healthy hair can keep the colour for longer and damaged cuticle releases it faster. Smart Beauty hair refreshers are a budget-friendly option to bring back the vibrancy of your hair colour. Simply apply it for 3 minutes and your red hair colour is refreshed! 

Wash your hair with lukewarm water

When you apply heat to your hair, its cuticle becomes porous and can’t hold the colour. Hot water and styling tools can definitely make your red hair colour fade quicker. Try to get used to colder water and style your hair just once a week to keep your colour bright.  

Sounds good? Now let's move to a fun part!
