How to Straighten a Wig: The Ultimate Guide for Sleek, Smooth Hair

Wigs offer endless styling versatility – from voluminous curls to chic bobs to ultra-straight locks. But what if your favorite wig came with curls and now you’re dreaming of a pin-straight look? Or maybe your wig has gotten frizzy over time and needs a refresh? Either way, knowing how to straighten a wig properly is essential. 

Straightening a wig isn’t as simple as running a flat iron through it – especially when you’re working with different wig materials. In this comprehensive guide, brought to you by Luxshine Hair with over 20 years in the hair industry, we’ll walk you through how to straighten a wig step-by-step, whether it’s made of human hair or synthetic fibers. Let’s get started!

Before You Start Straightening a Wig

Before diving into tools and techniques, it’s important to understand that not all wigs are created equal. The way you straighten a wig depends heavily on its material.

Human hair wigs are made from 100% real hair, allowing you to treat them similarly to your own. You can use heat tools like flat irons, blow dryers, or curling wands with minimal risk—if done properly.

Synthetic wigs, on the other hand, are made from plastic fibers like acrylic or polyester. These materials don’t respond to heat the same way natural hair does. In fact, applying direct high heat can melt or ruin synthetic wigs that aren’t labeled heat-resistant.

With over two decades of experience working with a wide range of wig types, our experts at Luxshine Hair have perfected the methods for safely straightening each kind. Below, we’ll break down how to straighten a wig based on its type, using various proven techniques.

How to Straighten a Human Hair Wig

Straightening a human hair wig is fairly similar to styling your own hair, but there are still some special considerations to keep your wig smooth, soft, and long-lasting.

Method 1: Using a Flat Iron

Step-by-step:

• Wash and condition the wig to remove any product buildup.
• Air dry or blow dry on low heat. Never use high heat on wet hair.
• Apply a heat protectant spray to shield the strands from damage.
• Divide the wig into small sections.
• Set the flat iron to 300–350°F (150–175°C).
• Glide the flat iron down each section slowly from root to tip.
• Repeat once if necessary, but avoid over-ironing.

Effects: This method gives a sleek, glossy finish and works well for eliminating frizz and wave patterns.

Results: Hair remains straight until your next wash and maintains its integrity with proper care.

Method 2: Blow Dryer + Round Brush

Step-by-step:

• Start with a damp, clean wig.
• Apply leave-in conditioner and heat protectant.
• Using a round brush, pull each section of the wig straight while aiming the blow dryer (set on medium heat) down the hair shaft.
• Repeat until the entire wig is dry and smooth.

Effects: Adds natural volume while straightening, suitable for clients who don’t like pin-straight styles.

Results: Creates a soft, bouncy straight look with movement.

Method 3: Hot Comb

Step-by-step:

• Use a hot comb (preferably electric) heated to around 300°F (150°C).
• Part the wig into small sections.
• Gently comb from root to ends in smooth strokes.
• Use a light serum afterward for shine.

Effects: Ideal for lace wigs and wigs with tight curls or kinky textures. Helps flatten roots and tame flyaways.

Results: Polished, natural-looking straight style with smooth roots.

Method 4: Straightening Cream

Step-by-step:

• Wash the wig and let it dry until slightly damp.
• Apply a small amount of straightening cream evenly through each section.
• Blow dry while brushing until straight.
• Use a flat iron if additional straightness is needed.

Effects: Loosens curls and waves gently, ideal for achieving a soft, relaxed straight look.

Results: Lightweight, touchable straight style without stiffness

How to Straighten a Synthetic Wig

If you’re wondering “can you straighten a wig made from synthetic fibers?”, the answer is yes, but with care. Here’s exactly how to straighten a synthetic wig safely.

Method 1: Steam Straightening

Step-by-step:

• Place the wig on a mannequin head and detangle.
• Fill a handheld steamer with water and turn it on.
• Pin down sections and gently brush them while running the steam over them.
• Continue until the section is straightened.
• Let the wig air dry and cool completely before touching.

Effects: Reshapes the wig fibers without melting them.

Results: A smooth and natural look without risking heat damage.

Method 2: Hot Water Technique (Dip and Comb)

Step-by-step:

• Boil water and pour it into a basin.
• Place the synthetic wig on a hanger or stand.
• Slowly pour the hot water over sections of the wig.
• Immediately comb each section straight while it’s still warm.
• Let air dry naturally.

Effects: Safe for most synthetic wigs, even non-heat-resistant ones.

Results: Restores straightness and reduces tangles in frizzy synthetic wigs.

Method 3: Flat Iron (Only If Heat-Resistant)

Step-by-step:

• Check that your wig is labeled “heat-resistant.”
• Set the flat iron to a very low temperature – no more than 270°F (132°C).
• Test on a small, hidden section first.
• Slowly glide the iron down the strands.
• Stop immediately if you smell burning or see fibers fusing.

Effects: Gives the most sleek, flat look for synthetic wigs—but ONLY if they are labeled as heat-friendly.

Results: A dramatic transformation but with some risk if improperly done.

Method 4: Roller Set + Steam

Step-by-step:

• Section the wig and wrap around large rollers.
• Use steam to set the hair.
• Let it dry for several hours or overnight.
• Remove rollers and brush gently.

Effects: Creates a straight style with natural body and curve at the ends.

Results: Perfect for heat-sensitive synthetic wigs.

Notes After Straightening a Wig

To maintain your wig’s health and appearance, keep the following tips in mind:

1. Let the Wig Cool Completely

• Human Hair: Allow cooling before combing to “set” the style.
• Synthetic: Never touch or manipulate the wig until it’s completely cool to prevent warping.

2. Use Wig-Safe Products

• Human Hair: Use serum, argan oil, or hair sprays made for wigs.
• Synthetic: Only use detangling sprays or shine mists specifically made for synthetic fibers.

3. Store Properly

• Human Hair: Store on a wig stand and cover with a silk scarf.
• Synthetic: Keep in a box or zip bag away from direct heat sources.

4. Limit Heat Exposure

• Human Hair: Can be heat-styled often, but frequent flat ironing still causes dryness.
• Synthetic: Should only be straightened occasionally, even if heat-resistant.

5. Rehydrate and Restore

• Human Hair: Deep condition after every few styling sessions.
• Synthetic: Spray with water + fabric softener mix to refresh texture.
