Catch up with our founder Katy Grimshaw

At Spectrum One Hair Extensions, we're all about passion, quality and innovation and who better to give us an inside look into the brand than our founder, Katy Grimshaw.

With over 20 years of hair industry experience, Katy has shaped Spectrum One Hair into the go-to destination for luxury professional hair extensions and hair education.

We sat down with Katy to talk all things hair extensions, her journey so far and what’s next for Spectrum One Hair.

How long have you been working in the hair industry?

God it feels like forever! I’ve been in the hair industry now for over 20 years. I started part-time at just 12 years old and by 16, I was working full time. My passion for all things hair has only grown stronger ever since.

What makes Spectrum One stand out from its competitors?

What's different about Spectrum One is we're a hairdresser-led brand, which makes a huge difference. We work hands on with hair day in, day out in our Spectrum One salon, so ensuring that our professional hair extensions range is only ever the highest quality for our clients not just in the salon but internationally, is what we pride ourselves on. We don’t just sell hair - we live and breathe it!

What are you most excited about in 2025?

There’s SO much to look forward to! We're currently working on launching new colours, constantly onboarding new brand ambassadors that the majority are coming to us which is so amazing that our brands awareness is growing rapidly. Along with many new exciting product launches planned in, so keep your eyes peeled for what's coming next. 

 

 

What is your favourite hair extension method?

I really love Tape hair extensions, we fit hundreds of sets in the salon every month and my favourite is our Invisible Tapes. They’re ultra-discreet and can be coloured right up to the root for a seamless blend, they're definitely one of our best selling methods.

 

What is your favourite Spectrum One product?

That has to be our Spectrum One Moisture Haircare range. We formulated it specifically for all hair types, but especially for professional hair extensions, to keep your hair looking and feeling its absolute best all year round. I know I'm biased but I honestly can never be without it!

 

If you could only pick one from the range, what’s your go-to shade?

Ooooh I have so many favourites I couldn't pick one out of all 35 but my top three would be our bridging tone shades Lady Ash, Creamed Ash and Teak are all so stunning and work beautifully blended for so many different looks.

 

What is the most underrated shade at Spectrum One?

Definitely Vanilla! It’s more of a yellow toned blonde, which actually makes it perfect for custom colouring, it takes on vibrant tones beautifully. I’d also say Rooted Steel is SO underrated, it’s amazing for bridging tones. 

 

What hair concerns can you solve with hair extensions?

Professional hair extensions are a game changer! Not only do they create volume, length, thickness and dimensional colours. They also help to cover issues such as thinning hair, to thicken out damaged hair, it can mask uneven growth and even help regrowth between your salon visits as your natural hair will continue to grow with our gentle hair-friendly methods.

 

 

What inspired you to start Spectrum One Hair Extensions?

I simply saw a gap in the market! At the time when I launched, there wasn’t a hairdresser-led brand that worked directly with customers and truly understood their needs. At Spectrum One, we offer expert guidance because we deal with these challenges firsthand, just like our trade clients on the salon floor will.

 

Which women inspire you?

Any and all women who are smashing it in business and lifting others up along the way inspire me! I love to see it & I love working with such a talented team of women across my three businesses.

 

What’s your greatest achievement?

Without a doubt, it's the business itself. Watching my team and the brands grow is something I am beyond grateful for. 

What advice would you give to businesswomen just starting out?

I'd start by suggesting to learn everything you possibly can about your industry! When I opened my salon, I knew everything about the workings of salons inside and out, but when I launched Spectrum One Extensions, I had no sales experience. If I could do it again, I’d focus on learning the business side first and always be prepared to give it your all! Every spare moment counts.

 

 

Where is the hair manufactured and is it sustainable?

Our professional hair extensions is manufactured in China. It is double-drawn, cuticle-correct and sourced ethically and sustainably.

How long have you been wearing hair extensions yourself?

For the past 15 years! I love how hair extensions allow me to add extra length and thickness whilst keeping my natural hair looking flawless. It adds so much hair confidence to my day to day, couldn't (& probably won't ever!) be without them. 

 

 

What’s your favourite thing about owning a business?

Honestly? The challenges. I thrive on problem solving and pushing through obstacles. I love seeing how myself, the business and my teams continue to grow every single day.
