Why choose us

Why Choose Wigs & Warpaint for K18 Treatment in Sheffield

K18 is not a conditioning mask. It is a patented peptide treatment that repairs the internal keratin chains broken by colour, bleach and heat. Most treatments coat the surface. K18 fixes what's underneath. The bioactive peptide works inside the hair cortex, reconnecting broken polypeptide chains — the bonds that give hair its strength and elasticity. Hair doesn't just feel better. It actually is better. Stronger, more resilient, behaving like it did before the damage. We use K18 as a standalone treatment and alongside colour services. Four minutes added to your appointment. The results are cumulative — every treatment builds on the last. If your hair has been through repeated colour, bleach or heat styling, this is not optional. It is essential.

Where the natural hair is healthy and strong enough to support them, extensions or targeted fillers can sometimes help restore the appearance of density following hormonal changes, menopause or a period of shedding. They do not treat the underlying cause of hair loss, so suitability is important. If your hair or scalp needs medical assessment rather than an extension service, we'll advise you accordingly.

Yes. A full head isn't always necessary. Targeted hair fillers and shorter extensions can be used to improve sparse sides, weaker areas, uneven growth, broken sections or areas that struggle to retain length. We colour-match and cut the added hair into your existing style so the result is designed around your haircut rather than simply making everything longer.

Absolutely. Many clients use extensions purely for density rather than length. We can keep your existing overall length while adding hair strategically to create fuller-looking ends, more body and a stronger shape.

We're at 11 West One Plaza, Fitzwilliam Street, Sheffield S1 4JB — right in the city centre, Near the end of division street in the complex where Akbars & Brewski is, Large Car parks at either side of complex.

Absolutely. We have a dedicated floor available for bridal parties and offer tailored wedding packages for hair and makeup.

Come to your appointment with your natural curl pattern — avoid straightening or blow-drying beforehand. We'll start with a consultation to understand your curl goals, texture and lifestyle so we can create the perfect shape.

A curly cut is performed on dry hair so the stylist can see how each curl naturally sits and account for shrinkage. This means the shape is built around movement and bounce, rather than cutting wet hair that behaves completely differently once dry.

Balayage is a hand-painted highlighting technique that creates natural, sun-kissed dimension. Unlike traditional foil highlights, balayage blends seamlessly as it grows out, giving you a softer, more lived-in look.

You can typically go 3–4 months between balayage appointments. It's one of the lowest-maintenance colour options because the freehand technique means no harsh regrowth lines.

A keratin treatment lasts 3–5 months depending on your hair type and aftercare routine. Results gradually fade naturally, so there's no awkward grow-out phase.

Yes. Our Kerasilk treatments are formaldehyde-free and safe for coloured, highlighted and bleached hair. In fact, keratin can help protect colour-treated hair by sealing the cuticle.

K18 is a molecular repair treatment that works in just 4 minutes. It reconnects broken polypeptide chains inside the hair fibre, reversing damage from colour, heat and chemical treatments. The results are long-lasting and cumulative.

K18 works on polypeptide chains, which make up the majority of hair structure, while Olaplex targets disulphide bonds. K18 requires no rinsing and works in 4 minutes. We offer both treatments and can advise which is best for your hair.

Yes, patch tests must be completed at least 48 hours before your colour appointment. This is a safety requirement we take seriously — no exceptions. You can pop into the salon or we can arrange one during a consultation.

Typically every 4–6 weeks for root colour. Balayage and highlights can go 3–4 months between appointments, making them a great lower-maintenance alternative.
