So glad this exsists

To anyone that has hair extensions and wears them regularly, this is a genuine must buy. I tested it out on my old extensions and they instantly changed from dull and tired to revived and a lot softer. It helps maintain the look of your extensions and the care to ingredients is amazing. I've not tried anything like this before and cannot speak more highly of it!

So good my sister stole my 1st one!

This product is so light, but so powerful, it literally makes my hair look like I have just had a salon visit or a maintenance appointment. And I love that on top of calming any frizz down and making me look like a don't have a split end in sight, I know it is also doing my hair and extensions so much good! Nourishing and protective even against UVA!

Yesssss

I was getting pretty sick of spending £400-500 every few months on hair extensions and having bits of them come out because of the product I was using… finally I can nourish my hair without destroying my investment… You can tell this is a high-quality formula… I’ll have this in my bathroom for as long as I have my extensions!

Brilliant product!

The Fox and Vamp Serum Extension Extender has quickly become one of the most essential products in my haircare routine. From the first application, I could feel and see the difference, it instantly adds softness, shine, and manageability without leaving any greasy residue. The formula is lightweight yet deeply nourishing, making it perfect for both natural hair and extensions.

Frequently asked questions

Can all hair types use the Extension Extender?

Yes! Our formulations have been developed to be highly effective on all hair types and textures, including straight hair, wavy hair, curly hair and coily hair and everything in between.

Does the Extension Extender work on all different extension applications?

Yes! We created the range to be able to work on all extension types and applications.

Do I need to have had Fox & Vamp extensions to be able to use the Extensions Conditioner?

Absolutely not, it does not matter where you have had your extensions put in, the Extension Conditioner will work for you.

Can I treat my clip in extensions with the Extension Extender, even when they are not in my hair?

100% yes, that is a great way to maintain your clip ins ready for your next wear. Remember to dry them and then hang and store them carefully in their packaging.

Why do I need a specific serum for my extensions?

Standard haircare can contain ingredients such as essential oils, rich moisturising oils, sulphates, silicones etc and these can weaken the bonds and adhesives of your extensions.

How did you develop the Extensions Haircare Range?

We are the first haircare range design specifically for extensions and we have worked directly with the bond and adhesive technologists to ensure our range only includes ingredients that are beneficial to extensions, and excludes any that are detrimental.  We then tested our formulations extensively to refine and perfect them to be the very best hair care for extensions.

How does the Extensions Extender extend the life of extensions?

The Extension Extender does not damage or deteriorate the bonds and adhesives of your extensions, like other conditioners can and so helps to reduce any loss or slipping which in turn helps to elongate the time between treatments. In addition the F&V Care Full Complex protects the hair, both extensions and naturally grown, from external aggressors such as styling, heat, weather, pollution, UV and chemical treatments.

My scalp is often irritated and is prone to flaking, can I use the Extension Extender?

We recommend you use the Extensions Extender down the length of the hair versus directly into the scalp to help prolong the bonds and attachments of your extensions. But all of our ingredients are scalp friendly and will not cause any irritation or flaking even when rinsing off. In addition we enriched the Care Full Complex with Glucose D and Snow Mushroom to hydrate and protect the scalp barrier to help prevent further issues.

Does the Extension Extender work equally well on my naturally grown hair as well as on my extensions?

Yes! All of the Care Full complex ingredients enhance naturally grown hair as well as extensions. A key ingredient is our multi-molecular Poly Saccharides + Hyaluronic Acid that acts like a 24 hour anti frizz humidity shield with built in heat activated thermal protection. We have tested the range on non extension wearers to ensure you can always use it, even if taking a break from treatments.

My hair is quite damaged and I have quite dry and brittle hair prone to breaking? Will the Extension Extender work on my hair too?

Yes the Extensions Extender contains key ingredients that help to improve and repair hair damage. We love our Vegan Silk Polypeptides from plant sources that create a breathable lightweight second skin effect on the hair with no build up. They repair hair from chemical and thermal damage, strengthening the hair shaft by 72%. The amount of damage is reduced by 56% and porosity is reduced by 63%.

I love the aroma of the Extensions Extender what is it?

The aroma of the Extensions Range is a beautiful bespoke Matcha fragrance developed just for us. We wanted you to love the experience of conditioning your hair with the Extensions Conditioner and its subtle light fragrance that works with any perfume.
