Heat Styling Wigs in New Zealand: Dos and Don’ts

CATEGORIES: ,

Heat styling gives you the freedom to personalise your wig, whether that's adding soft curls, smoothing frizz, or refreshing a style between washes. However, heat is also one of the fastest ways to damage a wig if it's used incorrectly.

At Custom Hair Company, we supply premium human hair wigs and hair toppers, alongside carefully selected synthetic wigs, to customers throughout New Zealand. This comprehensive guide explains exactly how to heat style your wig safely, what to avoid, and how to extend the life of your wig in New Zealand conditions.

Understanding Wig Fibres Before You Use Heat

Before styling, understanding how different wig fibres react to heat can help you feel more confident and in control. Not all wigs in New Zealand are designed for heat styling, and using the wrong tools can permanently ruin a wig.

Human Hair Wigs

Human hair wigs are made from real hair and offer the most styling flexibility. They can be:

  • Straightened
  • Curled or 'undone' style
  • Blow-dried
  • Restyled multiple times

However, unlike natural hair, human hair wigs do not receive oils from the scalp. This means they are more prone to dryness and require lower heat, fewer styling sessions, and extra moisture to stay in good condition.

Synthetic Wigs

Synthetic wigs are pre-styled and designed to hold their shape with minimal maintenance. Most standard synthetic wigs:

  • Cannot tolerate heat
  • Will melt, frizz, or stiffen permanently
  • Should only be styled using heat-free methods

Some heat-friendly synthetic wigs can handle low temperatures, but even these require caution. Always follow the manufacturer's guidelines or consult your NZ wig supplierbefore applying heat.

The Dos of Heat Styling Your Wig

Do Use the Correct Temperature for Your Wig Type

Temperature control is critical when styling wigs.

Recommended heat ranges:

  • Human hair wigs: 120–160°C
  • Heat-friendly synthetic wigs: As specified (often under 140°C)
  • Standard synthetic wigs: No heat

Using lower temperatures protects the hair cuticle and helps preserve the softness and movement that high-quality New Zealand wigs are known for.

Do Apply a Heat Protectant (Human Hair Wigs Only)

Heat protectant is not optional for human hair wigs. A lightweight, alcohol-free spray such as our 'Simply Stylin' Spray helps:

  • Reduce moisture loss
  • Prevent split ends
  • Protect colour integrity
  • Improve overall shine

Apply sparingly from mid-lengths to ends, avoiding the cap or lace areas.

Do Always Style on a Wig Stand or Mannequin Head

Styling a wig while it's off your head is safer and more effective. A wig stand allows you to:

  • Maintain the correct shape
  • Avoid pulling or stretching the cap
  • Style evenly from all angles

This is especially important for lace front and hand-tied wigs.

Do Work in Small, Controlled Sections

Large sections require multiple passes with heat tools, increasing damage. Small sections:

  • Style more evenly
  • Require less heat
  • Deliver a smoother, more natural finish

This approach also helps styles last longer in New Zealand's variable climate.

Do Let Each Section Cool Before Touching

Cooling allows the hair fibre to set into shape. Once the hair has cooled:

  • Gently separate curls with fingers or a wide-tooth comb
  • Avoid brushing immediately

This technique improves style longevity and reduces frizz.

The Don'ts of Heat Styling Your Wig

Don't Assume All Wigs Can Handle Heat

One of the most common mistakes is assuming all wigs can be styled the same way. Applying heat to the wrong type of wig can result in:

  • Melted fibres
  • Permanent frizz
  • Loss of shape

If in doubt, always ask your NZ wig supplier.

Don't Use High Heat "Just Once"

Even a single exposure to excessive heat can cause irreversible damage. High heat:

  • Weakens hair fibres
  • Causes dryness and breakage
  • Reduces the lifespan of the wig

Professional-quality wigs should always be treated gently.

Don't Heat Style a Dirty or Damp Wig

Heat locks in:

  • Oils
  • Sweat
  • Environmental pollutants

Always ensure your wig is freshly washed, fully dry, and free from product build-up before styling.

Don't Apply Heat Near the Roots or Lace

Direct heat near the base can damage:

  • Lace fronts
  • Mono tops
  • Knots and ventilation

Keep heat tools at least 2–3 cm away from the roots to protect the wig's construction.

Don't Heat Style Too Frequently

Frequent heat styling can reduce softness and cause damage over time, so rotating between wigs or choosing pre-styled options can help you feel more confident in caring for your wig's longevity. Unlike natural hair, wigs don't regenerate. Frequent heat styling will:

  • Reduce softness over time
  • Increase shedding
  • Dull the finish

Many experienced wig wearers in New Zealand rotate between multiple wigs or choose pre-styled options for everyday wear.

Heat-Free Styling Methods to Extend Wig Life

Heat-free styling is one of the best ways to preserve both human hair and synthetic wigs.

Popular methods include:

  • Foam rollers for soft curls
  • Velcro rollers for volume
  • Heatless curling rods
  • Overnight setting techniques

These methods are particularly effective for synthetic wigs in NZ and for maintaining curl patterns without damage.

How Often Should You Heat-Style a Wig?

How often you should heat-style your wig depends on its fibre type: human hair wigs can be styled occasionally, while synthetic wigs should be styled sparingly or avoided unless heat-friendly. As a general guideline:

  • Human hair wigs: Occasional heat styling only
  • Synthetic wigs: Avoid heat unless heat-friendly

If you wear your wig daily, aim to:

  • Reserve heat styling for special occasions
  • Refresh styles using steam-free or heat-free methods
  • Schedule professional maintenance if needed
