You’ve just left the salon with a gorgeous new hair colour, feeling like a brand-new person. But as you admire the vibrant shade in the mirror, a question pops into your head: how long will this beautiful colour actually last? It’s a common thought, and the answer isn’t the same for everyone. The lifespan of your hair colour depends on a beautiful mix of factors, from the type of colour you chose to your daily habits.
The Type of Colour Makes a Big Difference
Not all hair colour is created equal. Permanent colour, which lightens your natural pigment, typically lasts the longest—anywhere from six to eight weeks before your roots become noticeable. Demi-permanent colour, which adds shine and tone without lifting, gently fades over about 24 to 28 shampoos. Semi-permanent colour, which simply coats the hair shaft, is the most temporary, often lasting through six to twelve washes.
Why Your Colour Fades Over Time
Even the most resilient colour will eventually fade. The main culprits are washing and the environment. Hot water opens the hair cuticle, allowing colour molecules to escape. Sun exposure acts like a natural bleach, while chlorine and saltwater can also strip away your hue. Even your styling tools contribute, as high heat can break down the colour over time.
Simple Ways to Make Your Colour Last Longer
The good news is that you have a lot of power to extend the life of your colour. Switching to a sulfate-free shampoo and conditioner system designed for colour-treated hair is the most impactful step. Try to wash your hair less frequently, and when you do, use lukewarm water instead of hot. Before heading to the pool or the beach, wet your hair and apply a leave-in conditioner to create a protective barrier. And don’t forget a heat protectant spray before using any hot tools!
When to Consider a Colour Refresh
You’ll know it’s time for a touch-up when you see your natural roots growing in, usually around that six to eight week mark for permanent colour. The overall vibrancy might also start to look a bit dull or brassy. For semi and demi-permanent colours, you can refresh your shade as soon as you feel the colour has lost its punch.
By understanding what affects your specific colour and adopting a few gentle hair care habits, you can keep your hair looking vibrant and healthy for as long as possible. It’s all about giving your colour the love and protection it deserves.
