How Hair Colouring Really Works


Hair colouring is a billion dollar industry with so many options to choose from. From basics like highlights and colouring, to more complex treatments like ombre and balayage, the possibilities are endless! But have you ever stopped to think about the chemistry behind it all? How does hair colouring actually work? What’s being used in each application and how does it affect your hair? In this post, we’ll explore the science of hair colouring and provide tips on how to keep your hair colour looking its best after each appointment. Read on for a crash course in everything from Sudbury hair colour basics to expert tips from your RondezVous Colour Lounge hair stylists!


An Introduction to Hair Colouring

Hair colouring is a process of adding pigment to the hair shaft to change the hair colour. There are two main types of hair colouring: temporary and permanent.

Temporary hair colouring is achieved by adding a deposit-only colour to the hair shaft. This type of colour washes out over time and does not penetrate the cuticle layer of the hair.

Permanent hair colouring is achieved by adding both a deposit-only colour and a lift (bleaching) agent to the hair shaft. The lift agent opens up the cuticle layer of the hair so that the deposit-only colour can penetrate into the cortex, or middle layer, of the hair. The new pigment then combines with the existing pigment in the cortex to create a new, permanent hair colour. Fascinating, right?!


The Science of Hair Colouring

Now we’re going to get a bit deeper into your chemistry lesson, but don’t freak out! Most hair dyes contain a mix of chemicals that work together to penetrate the hair shaft, deposit colour and then seal in the new shade. The exact mix of ingredients varies between brands, but generally speaking, here’s what you’ll find in hair dye:


-Permanent hair dyes: Ammonia or ethanolamine breaks down the cuticle layer so the colour can penetrate, hydrogen peroxide lightens hair by breaking apart the natural pigment molecules, and resorcinol helps to open up the cuticle. Dye molecules and pigments are then deposited into the cortex.

-Semi-permanent and demi-permanent dyes: These contains no ammonia or bleach, and instead rely on smaller colour molecules that infiltrate the cuticle and bond with natural pigment to deposit colour. Oxidation may also be used to help develop semi-permanent shades.

Once the desired colour is achieved, another set of chemicals known as ‘colour fixatives’ are used to help lock in the new shade and prevent it from fading too quickly. These usually include sodium sulfate, polyquaternium compounds or EDTA.


Sorry for the intense science but as much as we think of hair colour as artistic and creative, the ingredients to make it work are based on complex science. Hair colouring can be very complicated and that’s why we already recommend that for your Sudbury hair, you come and see the experts.

Pros and Cons of Hair Colouring

When it comes to hair colouring, there are a few things you should know before taking the plunge. First and foremost, as you have read above, hair colouring is a chemical process that can be damaging to your hair if not done correctly. If you're considering hair colouring, it's important to weigh the pros and cons to decide if it's right for you.


On the plus side, hair colouring can be a great way to change up your look and add some dimension to your hairstyle. It can also be used to cover up any unwanted grays. And, if done correctly with your RondezVous Colour Lounge hair colour expert, the process can actually help protect your hair from damage.


On the downside, however, hair colouring can be very damaging to your hair if not done properly. It can also be expensive and time-consuming to maintain. If you're not careful and try to do it yourself, you could end up with uneven color or even worse - orange hair!


So, what's the verdict? Is hair colouring worth it? Ultimately, that decision is up to you. If you're considering hair colouring, come and get a free consultation at the best hair salon in Sudbury, RondezVous Colour Lounge! We will ensure that you get the best possible results.


How long does hair colour last in your hair?

How long does hair colour last in your hair? This is a question that many people ask, and the answer may surprise you. Hair colour can last anywhere from a few weeks to several months, depending on the type of colouring product used, the condition of your hair, and how often you wash it. If you're using a semi-permanent hair colour, it will typically last between 5 to 10 washes. Whereas a demi-permanent hair colour, which uses a small amount of peroxide, will last longer, typically around 24 washes.


If you're using a permanent hair colour, it stays until your hair grows out (although the colour will fade if you aren’t maintaining it properly. Of course, these are just general guidelines - everyone's hair is different, so results may vary. To make your hair colour last longer, try using a sulphate-free shampoo and conditioner (which won't strip away the colour) and avoid washing your hair too often. And if you do notice your colour fading prematurely, book in for a touch-up sooner rather than later to keep your locks looking their best.
