Try them for yourself
Spoiler: not all extensions are created equal.

So many brands cut corners with cheaper hair, leaving you (or your clients) repurchasing every few months. We’ve seen it all: tangles, matting, dry ends after a few washes… basically extension horror stories. You deserve better.

That’s why we created SH Signature Extensions. Built to last, salon-approved, and backed by our 12-month quality guarantee (with the right care).

Life’s too short for extensions that give out early
Our most Frequently asked questions

FAQ's

How do I care for my hair extensions?
  • No keratin or protein based products: Keratin and Protein can weaken the bonds and void your 12-month quality guarantee.
  • Hydration is key: Like your natural hair needs regular care, your extensions do too. Oil your extensions regularly and use gentle products like MUK Ultra Soft Shampoo & Conditioner. These are hair extension approved.
  • Book maintenance every 4–6 weeks: This keeps up with your natural hair growth
  •  Apply Leave-in conditioner before swimming: This helps protect your extensions and keep them soft, especially in salt water or chlorine.
  • Plait before bed: This helps to avoid tangling.
  • Avoid daily heat styling and never apply heat to the bonds.
What products CAN'T I use on my extensions?

Any products containing keratin or protein will dry out the extensions and make them feel brittle. Avoid anything that is labelled repairing and reconstructing. Check all ingredient labels or risk your hair not being covered by warranty.

You need to also be careful with sunscreen. Choose a mineral free one that DOESNT contain avobenzone and octocrylene.

We highly recommend the Muk Ultra soft range.

What Makes SH Extensions Different?

We don’t cut corners with harsh chemicals or silicone coatings. Many brands process their hair this way to create a temporary silky feel, but once the coating wears off, the hair quickly becomes dry, brittle, and tangled.

Our SH Signature Extensions are crafted from higher-quality Remy double-drawn human hair (thick from top to bottom) with minimal processing. That means:

  • They stay soft and silky wash after wash
  • They last longer without matting or shedding
  • They look and feel natural for months, not weeks

With SH, what you see on day one is what you’ll keep loving for the long run.

Because life’s too short for extensions that give out early.

How long does my hair need to be to get extensions?

The shortest your hair should be for a natural result is approximately 2-3 inches long. If you are unsure whether your hair is long enough please contact us to book a consultation so we can assess this for you or send us a photo so we can let you know what we recommend.

Can I colour or heat style the extensions?

Heat: Yes you can style your Hair Extensions as they are 100% Human Hair. It is recommended to always use a heat protector when styling your Hair Extensions, as you should be with your own hair too.

Colouring: Do NOT bleach. The extensions are very porous, so we advise that you do a spot test first, as the colour will vary from batch to batch.

If you're coUse no more than 3% developer. Please note you will be doing this at your own risk.

What’s the removal process?

For application and removals, these semi-permanent methods must be done by a trained hair extension specialist. This ensures your extensions are applied safely, removed without damage to your natural hair, and reinstalled for a seamless, natural finish.

Your stylist will gently remove the extensions using professional tools and techniques. No pulling, no breakage, no stress on your hair.

Will they hurt or damage my natural hair?

The methods that we specialise in are the most up to date methods on the market. No damage or stress should be causes to your hair / scalp, providing you follow our simple Maintenance Plan. Correct application technique is vital to prevent hair breakage and if not applied correctly they can be painful. This is normally caused by applying them too close to the scalp, an incorrect amount of hair placed in the attachments, or the extensions not lying flat to your head.
