Colour Excellence Highlights Brightener for Blondes UPDATE

Colour Excellence Highlights Brightener for Blondes

I bought this a couple of weeks ago because my highlights were looking dull and it was too soon to have them re-done. I like to prolong my visits to the hairdresser to preserve the condition of my hair and my purse.

Adding Vitamin C powder to skin care products to dull blemishes and brighten the complexion has been a bit of thing for a while now.

But the method of crushing up Vitamin C tablets and mixing the powder with a clarifying shampoo to tone down a vivid home hair colour dye job, has been around for years.

The idea behind Colour Excellence Highlights Brightener for Blondes is that it does the same thing with highlights, lifts off build up and brightens highlights as if they’ve been freshly done.


  • Highlights Brightener works to naturally remove product residues and environmental build-up to keep highlights looking as good as new – without harming your hair
  • Maximum colour definition for sharper, longer lasting highlights
  • Naturally removes hair product residues and environmental build-up
  • Counteracts the tendency of Highlights to absorb styling products and environmental damage
  • Contains extract of Chamomile


Step 1. Mix and Shake
Carefully pour all of the Vitamin C powder from the sachet into the bottle and shake vigorously until the powder is completely dissolved. Leave to stand, but use within 1 hour. Shampoo your hair and towel dry. (Do not use a 2-in-1 shampoo and do not condition at this stage.)

Step 2. Apply
Shake product once more prior to application. Squeeze the mixture carefully onto the towel-dried hair. Only use as much solution as your hair length demands. Once applied, massage thoroughly as you would a shampoo and then wash hands. Comb through to ensure even distribution (ideally with a wide toothed comb).

Step 3. Rinse
Rinse the hair thoroughly with warm water. Then condition as normal if required. (I’d use a shed load of light conditioner).


There are lots of positive reviews on the Boots website:

I used this product before going to a friend’s wedding as I didn’t have time to visit the hairdresser. It freshened up my highlights, and left my hair feeling soft and shiny. It was really easy to apply and smelt pleasant.

I was pleased with the results of this product. Great to use in between visits to the hairdressers for a boost / lift.

This highlighter is subtle but effective, my blonde hair is much more shimmery and glitters in the sun! Lovely pale golden (but not brassy) colour, hair strands look like golden threads! (poet)

However, I found the ‘negative’ reviews just as revealing. Even if the effects only last a week, it’s a great quick fix for a special event when you can’t get to the hairdressers.

Plus, when people didn’t see any tangible difference to the colour of their, they agreed that hair felt better conditioned.

I wouldn’t say my hair was considerably brighter than before, but it has lifted it a bit (like it generally does after being washed in the salon). I think it has simply stripped out a lot of product build up, but I would consider using it again as it’s cheaper than a salon wash!

It did make my highlights brighter for about a week or so and left my hair nice and soft, but I was disappointed it didn’t last long.

After using this brightener I did not see and difference. I asked numerous friends and family and they could not see any difference either! It did make my hair feel much more softer, manageable and conditioned though.

I have to say I didn’t notice much difference in colour, however, it did make my hair silkier which was nice.

I’m not really convinced that this is any better than other colour preserving shampoos on the market in terms of the colour it’s self. It did however leave the hair feeling very nicely conditioned and nourished.

I’ve got bleach highlighted hair and although this did condition my dry ends very well it didn’t look any fresher.

Used it on my highlights and was actually really impressed with the difference it made. You could really notice that they were brighter however it only lasted for a little over a week.

I haven’t used it yet because of my recent ‘maths‘ discovery.

Super Shiny (blonde) Hair Maths

Plus, I’m having a sprinkling of highlights put in tomorrow for all the Christmas activities coming up. But I certainly will use it when my highlights start to look tired again.

UPDATE: 19th January 2016

This was an interesting one – it was a success, but maybe not the ‘success’ I was looking for…

Mixing the powder with the solution was straightforward, although I suggest you only cut off a corner of the powder sachet, the opening of the applicator bottle is not wide and you could (like me), spill some of the powder.

Another tip is to use a lathering/foamy shampoo (or perhaps just baby shampoo), instead of a SLS (the foaming agent, Sodium Lauryl Sulfate), free one. I find some of the SLS free shampoos make hair too squeaky to comb through unless I use a shedload of conditioner. You won’t be using conditioner at this stage, but you will want the comb to glide easily through your hair.

As the mixture was standing, I re-read the instruction leaflet and had a mini freak out at:

Not suitable for use on uncoloured grey/white hair.

The thing is, you’re going use this product when your highlights have lost their newness, depending on how fast your hair grows, that means there will be roots, and if you’re of a ‘certain’ age, maybe some of those roots will be grey or white.

I had visions of my roots turning orange, so I skipped the ‘massaging in like a shampoo’ part, avoided all partings, squeezed the solution directly onto my gloves, dabbed it along the lengths and combed through about a third of the way down.

I also used only half the contents of the bottle – overly cautious perhaps? Not at all. I vividly recall dabbling with a ‘Light Ash Blonde’ home hair dye many (many) years ago and ending up with a very distinctive greenish hue to my hair.

You can feel an immediate difference to the texture of the hair after rinsing off the conditioner, it’s softer and after blow drying, hair is definitely silkier.

Colourwise, the end result in my case was as if a veil had been lifted from my hair and my highlights really did pop! My hair reflects light and actually shines (although keep in mind that I only did it last night).

The downside is that my roots are noticeably darker. I’m talking dark, as in ‘can be seen from space’ dark. Dark as in almost black! Fortunately, I’m booked in on Saturday for a ‘T’ section of highlights, but I think this is a useful lesson. Colour Excellence does work and it will make your highlights looks fresh and vibrant, it also softens and conditions hair – but just be careful if your roots need doing!

      Hi Mandy, See above update. It works, but be careful if you have obvious roots!
