Is PurePlex a viable alternative to OlaPlex?

PurePlex Hair Dye

It's no secret that OlaPlex is all the rage right now. From hairstylists to beauty gurus and everyone in between, this 'holy grail of haircare' is all anyone can talk about. But as tempting as the testimonials are, I couldn't justify parting with that kind of cash for a product that might not deliver the same splendid results on my hair.

So, what did I do? If you know me well enough, then you'll know that I began an internet deep dive to find a more affordable alternative to this so-called magic product, which is how I found Knight and Wilson.

As a newly established brand exclusive to Superdrug, I hadn't previously heard of Knight and Wilson. But when I discovered that they had created their own OlaPlex dupe formula, called PurePlex, I was keen to find out more.

After doing a little bit of reading, I found out that the Knight and Wilson PurePlex range aims to colour your hair while protecting against damage and breakage, while rebuilding the natural structure of your hair, leaving it stronger, healthier, and more voluminous. Sounds perfect, right?

Who Are Knight and Wilson?

Knight and Wilson have made their mark with a unique colour range curated to entice any hair dye addict. So, whether you're looking to make a statement with a vibrant colour or are just hoping to tame those pesky greys, you are guaranteed to find something to your taste in their collection.

Their goal is to create salon-quality products for prices that suit everyone's budget so there's no need to worry about damage to your purse on this occasion. As if they couldn't get any better, they are also completely cruelty-free and suitable for vegans too.

Contents, Packaging, and Cost

All you packaging snobs out there will be pleased to know that despite the low price point of just £7.99, Knight and Wilson have taken care to create attractive packaging that looks both professional and premium. This is a bargain in comparison to the real OlaPlex products.

Unlike the majority of dyes that come with three parts included (cream developer, colourant and a conditioning sachet), this dye comes with an added step, the bond reconstructing treatment. You are also provided instructions and gloves for safely applying the dye.

Some would say PurePlex is revolutionary.

What Makes This Dye Different?

As mentioned above, this dye comes with an extra step in the hair colouring process which promises to reconstruct the hairs bonds. This adds to the overall health and strength of your hair.

In addition to this, Knight and Wilson PurePlex dye is full of ingredients that are actually beneficial to your hair such as Shea Butter and Argan Oil. These particular ingredients are included in the colouring formula and have amazing benefits to the overall health of your hair.

Shea Butter, for example, is great for resolving scalp problems and is ideal for sensitive skin, while Argan Oil is rich in vitamin E which contains antioxidants to encourage hair growth.

My Experience

As I have waist length and relatively thick hair, I decided that two boxes of dye would be necessary. So, you can bet that I was pleasantly surprised when I later discovered how generous this product is with its contents. In the end, I only ended up using one box of the dyes I bought!

The shade I chose was 7.5 Mahogany Blonde, which is a rich auburn colour - perfect for what I had in mind.

After mixing the colourant and cream developer together, I applied the dye to my hair and left it for the recommended time. While the consistency is easy to work with, doesn't clump together, or drip all over the floor (like so many products do), it does smell like your standard chemical hair dye, so make sure you apply it in a well-ventilated area.

The only issue I did encounter was with the dye bottle itself, which had three strange holes around the neck of the nozzle instead of just one main one on the end. This little surprise meant that some dye escaped onto the floor, but it is something I will know to be cautious of for next time around.

After the processing time had passed, it was time for me to rinse out the dye and coat my hair in the bond reconstructing treatment for 15 minutes. This was by far my favourite part of the process. It involved covering your hair in a lovely, thick, and creamy conditioner-like product that smells very strongly of bananas. The product is then rinsed out and followed up with conditioner.

The entire process was no more complex than any other hair dye that I have used in the past and took just over an hour and a quarter to complete. It has left my hair feeling nourished and silky smooth and like I've just been to a hair salon.

Don't take my word for it, try it yourself.

Final Thoughts

While my hair colour didn't go exactly to plan (completely my own fault for not lightening my hair enough in the beginning and nothing to do with this dye at all), I am so impressed with how this dye has completely transformed the condition of my hair. Though my hair has never been in what would be classed as bad condition, it was previously a little lackluster and dry, especially at the ends. Now, it has a lovely shine and feels so healthy and strong.

This dye is definitely going to be my go-to colourant from now on, and I'm already looking forward to trying out more of their products in the future.

If you haven't already tried Knight and Wilson I strongly recommend that you do. Your hair will thank you!

Questions & Answers

Question: Will Knight and Wilson pureplex hair dye cover greys?

Answer: On the box it says it is intended to cover grey hairs as well, however I don't have experience with this myself so it would be a case of trying it out for yourself and seeing how things go.

Question: Do I need to do a skin test before using Knight and Wilson Pureplex hair dye? Does it cause allergic reactions?

Answer: All products reccomend that you conduct a patch test before completing a full application in case there is a reaction. I didn't have an allergic reaction to it whatsoever but that doesn't mean others won't.
