Can You Colour Hair After Keratin Treatment

Hey there, gorgeous! So, you’ve just emerged from the magical land of the keratin treatment, and your hair is feeling all silky, smooth, and ridiculously shiny. High five! But now, a new burning question might be flickering in your brain like a rogue disco ball: "Can I actually put some colour on this masterpiece?" Let's dive in and spill the tea, shall we?
First things first, let's give a little round of applause for keratin treatments. They’re like a superhero cape for your frizz, a smoothing serum on steroids, and a ticket to a good hair day, every day. You’ve invested time, maybe a bit of coin, and definitely some serious trust in your stylist. So, the thought of messing with that perfection is, understandably, a little nerve-wracking.
So, to answer the big question straight up: Yes, you absolutely can colour your hair after a keratin treatment! But, like most good things in life, there are a few tiny details to keep in mind. Think of it like a secret handshake; get it right, and you’re golden.
Must Read
The Lowdown on Colour and Keratin
What’s the deal, anyway? Well, keratin treatments work by infusing your hair with keratin, a protein that’s naturally found in your strands. This process smooths the cuticle, that outer layer of your hair, making it less porous and more resistant to humidity (bye, frizz!).
Now, when you introduce hair colour, especially if it’s a harsher chemical process like bleaching or lifting, it can potentially… well, let’s say tickle the keratin coating a bit. This doesn’t mean disaster, but it’s like trying to paint a perfectly polished car – you want to use the right kind of paint and not go too wild with the sandpaper, right?
Timing is Everything (Seriously!)
This is probably the MOST important piece of advice I can give you. Patience, my friend, patience! Most stylists will tell you to wait at least two weeks after your keratin treatment before you even think about dyeing your hair. Why the wait? Because your hair needs time to fully absorb and settle with the keratin. It's like letting a new cake cool before you frost it – you don't want to mess up the foundation!
During those two weeks, your hair is basically having a spa day. It's getting used to its new, smooth existence. Rushing the colouring process could mean that the colour doesn't take as evenly, or worse, it could strip away some of that precious keratin you just paid for. And nobody wants that. Nobody.
Some might even recommend waiting longer, especially if you’re going for a dramatic colour change or a colour that’s known to be a bit more aggressive. Listen to your stylist! They know your hair best, and they’ve seen it all.

What Kind of Colour Can You Use? The Great Divide!
Alright, so we know when, but what about what? This is where things get a little more nuanced, but still totally manageable.
1. Colouring Before Keratin (A Sneaky Option!)
This is often the easiest route if you’re planning both. Colour your hair before your keratin treatment. Why? Because the keratin treatment itself can actually enhance the vibrancy of your existing hair colour and give it a beautiful shine. It's like putting a protective top coat on a freshly painted nail – it seals it in and makes it pop!
If you're going from dark to light, however, you'll likely want to do that lightening process before the keratin treatment. Bleaching is a whole other beast, and it’s best to get all the heavy lifting done before you seal everything in with keratin.
2. Colouring After Keratin: The "Gentle Approach"
So, you didn’t colour before, and now you’re itching for a change. No worries! The key here is to be gentle. Think less "chemical warfare" and more "spa treatment for your hair."
Semi-Permanent and Temporary Dyes: Your Besties!

These are your absolute safest bet. Semi-permanent dyes don't contain ammonia or peroxide, which are the main culprits that can strip colour and damage hair. They deposit colour onto the surface of your hair, and they tend to fade gradually, which is great because it means less commitment and less risk of harsh damage.
Think of those fun, vibrant colours or subtle glosses. They’re perfect for adding a touch of pizzazz without compromising your smooth locks. They might not last as long as permanent colour, but hey, more opportunities for fun colour changes, right? It’s like a buffet for your hair!
Permanent Dyes: Proceed with Caution!
Now, permanent dyes are where you need to be a little more strategic. Because they use ammonia and peroxide to lift the natural pigment and deposit new colour, they can be more drying and potentially impact the keratin.
If you’re opting for a permanent colour, here’s what you should absolutely do:

- Talk to your stylist first! I can’t stress this enough. They can assess your hair’s condition and recommend the best approach.
- Choose a demi-permanent or ammonia-free permanent dye if possible. These are gentler alternatives that are less likely to strip the keratin.
- Avoid drastic lightening. Going from brunette to platinum blonde immediately after a keratin treatment is like asking your car to win the Indy 500 after a quick oil change. It’s too much too soon. Stick to darker shades or subtle highlights for the first few colouring sessions.
- Deep condition regularly. After colouring, your hair will appreciate some extra TLC.
Bleaching: The Big No-No (For a While!)
Let’s just be clear: Bleaching immediately after a keratin treatment is generally a bad idea. Bleach is the heavyweight champion of hair colour removal, and it will very likely strip away a significant portion of the keratin, leaving your hair dry, brittle, and… well, back to its pre-keratin state, but potentially more damaged. If you’re dreaming of being a blonde bombshell, you’ll need to plan this out carefully. It usually involves doing the bleaching before the keratin, or waiting a significant amount of time (think months, not weeks) and being prepared for intensive conditioning.
Tips for a Colourful Keratinized Future
So, you've navigated the timing and the type of colour. What else can you do to keep your hair looking fabulous?
Sulphate-Free Everything!
This is non-negotiable. Always use sulphate-free shampoos and conditioners, especially after a keratin treatment and when you colour your hair. Sulphates are like tiny little aggressive scrubbers that will strip away both your keratin and your hair colour. They’re the arch-nemesis of smooth, colourful hair. So, ditch the sudsy monsters and embrace the gentle goodness!
Condition, Condition, Condition!
Your hair has been through a process, and now it’s rocking a new hue. It deserves some serious pampering. Invest in a good quality deep conditioner or hair mask. Use it at least once a week to keep your strands hydrated and your colour vibrant. Think of it as giving your hair a hydrating hug.

Towel-Dry Gently
When you're done washing, don't go roughing up your precious locks like you're trying to dry a beach towel. Gently squeeze out excess water and then pat your hair dry with a microfiber towel. Less friction means less frizz and less damage to both the keratin and your colour.
Avoid Excessive Heat
While keratin treatments help with heat styling, we're all about longevity here. Try to minimise your use of hot tools like straighteners and curling irons. If you do use them, always apply a heat protectant spray. Heat can cause both keratin and colour to degrade faster.
Rinse with Cool Water
This is a little trick that can help seal the cuticle, making your hair shinier and your colour last longer. So, when you’re in the shower, embrace the cool rinse for a few seconds at the end. It's a small step with a big impact!
The Takeaway: Shine Bright, Colour Boldly (But Smartly!)
Ultimately, the answer to "Can I colour hair after keratin treatment?" is a resounding yes, with a little love and attention. Your hair is a canvas, and you have the power to create beautiful art on it. By being mindful of timing, choosing the right products, and giving your hair the care it deserves, you can absolutely enjoy both the smoothness of keratin and the joy of a fresh new hair colour.
Think of your hair as a special garden. You've nurtured it, given it the best soil (keratin treatment!), and now you want to add some beautiful flowers (hair colour!). You wouldn't just haphazardly throw seeds around, right? You'd prepare the soil, choose the right plants, and give them the best chance to bloom. Your hair is no different!
So go forth, my beautiful friend! Get that vibrant streak, that subtle balayage, or that rich, all-over colour you’ve been dreaming of. With a little knowledge and a lot of self-care, your hair can be the most stunning, silky, and colourful masterpiece you’ve ever seen. And isn't that just the most delightful thought? Keep shining!
