How to Style Clip-In Extensions With a Hot Air Brush

Yes, you can style clip-in extensions with a hot air brush, and it is the easiest way to make them blend. Use 100% human hair clip-ins, put on a heat protectant, and keep the brush on low or medium. Style your own hair and the extensions together, so the ends bend the same way. That shared shape is what hides the line between your hair and theirs.

This guide covers the order to work in, the settings to use, how to pick a clip-in set that takes heat well, and the small mistakes that make extensions look like extensions.

Quick picks

• Best starter set: LaaVoo 7-piece Remy Clip-In
• Best seamless set: Vivien PU Genius Seamless Clip-In
• Most invisible weft: LaaVoo Injection PU Clip-In
• Tool to style them with: Dreame AirStyle Pro

Why a hot air brush works so well with clip-ins

Clip-ins look fake for one reason more than any other: the extensions and your own hair have a different shape. Your hair might be flat at the root with a slight bend, while the extensions are dead straight or curled from the factory. Where they meet, you see a step.

A hot air brush fixes that in one pass. It dries, smooths and bends the hair at the same time, so the brush gives your hair and the extensions the same soft curve at the ends. It also uses moving air rather than a hot plate pressed on the hair, so it is gentler than a flat iron for everyday styling.

It is also quicker than a dryer and round brush. You hold one tool, not two, which matters when you have more hair on your head than usual.

Check this before any heat touches your extensions

All three sets in this guide are listed as 100% Remy human hair. Remy means the cuticles all face the same way, which helps the hair stay smooth and tangle less. It is the label to look for.

Two more checks:

• Heat protectant. Extensions get no oil from your scalp, so they dry out faster than your own hair. LaaVoo's own care tips tell you to use heat protection, and it is good advice for any brand.
• Clips and wefts. Keep the hot air off the clips and the weft base. You are styling the lengths, not the top inch.

The settings to use

Start lower than you think. Human hair extensions have already been processed, often colored, and they do not grow back. Low or medium heat with steady tension gives a smooth finish without frying the ends.

If your tool only has low and high, use low on the extensions and save high for your own roots.

How to style clip-ins with a hot air brush, step by step

1. Start with dry or nearly dry hair. Rough-dry your own hair to about 80 percent. The extensions should be fully dry before you clip them in, so the clips grip and the wefts sit flat.
2. Section and clip in from the bottom up. Part a horizontal line at the nape, tease the root very lightly for grip, and snap in the widest weft. Work up toward the crown with the narrower pieces. Leave at least an inch of your own hair around your face and part.
3. Protect the lengths. Mist heat protectant over your hair and the extensions, mid-lengths to ends. Brush through gently from the bottom up to remove tangles.
4. Brush in sections the width of the brush. Take a section that holds both your hair and the extension under it. Place the brush under the section a few inches below the clips, not at the scalp. Glide down slowly to the ends.
5. Turn the ends under or out. At the bottom, roll the brush a half turn and hold for a few seconds. Do the same shape on every section, so the extensions and your hair end in the same curve.
6. Lock it with the cool shot. Hold the cool setting on each section for a few seconds before you let go. The shape sets as the hair cools.
7. Finish your own top layer. Do your roots and crown last, on your own hair only. This is where you can use a bit more heat for lift, since it is not covering any clips.

Styling extensions on their own, before you clip them in

On busy mornings you can style the wefts before you put them in. Clip each weft to a towel over the back of a chair, or hang it from a hanger. Brush them out, mist on protectant, and run the hot air brush down each one with a half turn at the end.

This keeps all the heat off your own hair. The trade-off is that the curve will not match your hair exactly, so give your own lengths a quick pass once everything is in.

The picks, one by one

LaaVoo 7-piece Remy Clip-In: best starter set

This is the classic clip-in: seven pieces, 100 grams per set, 100% Remy human hair, sold in lengths from 14 to 24 inches. LaaVoo says the hair can be dyed because it is human hair, though going darker is easier than going lighter.

At 100 grams it suits fine to medium hair, or anyone who wants to add length rather than a lot of volume. If your hair is thick, look at the heavier sets below so the ends do not look thin next to your own.

Vivien PU Genius Seamless Clip-In: best seamless set

The PU Genius set uses thin, flexible PU wefts instead of a fabric weft, so it lies flatter against your head. It is a seven-piece set, 135 grams up to 18 inches and 150 grams from 20 inches, in lengths from 14 to 24 inches. Vivien describes it as heat-styling friendly, with silicone-backed clips for grip.

The flatter weft is the reason to pick it. It shows less when your own hair is fine or when you wear it half up. Some colors are sold as pre-sale, so check the shipping date on the listing.

LaaVoo Injection PU Clip-In: most invisible weft

The injection PU style is built so the hair looks like it grows straight from the scalp, with a thin PU edge that LaaVoo says stays comfortable for all-day wear. It is a thick set, 135 grams at 18 inches and 150 grams at 20 and 22 inches, in 100% Remy human hair.

It costs more than the classic set. You pay for a weft that hides well even when your part moves or the wind catches your hair. If you have tried clip-ins before and hated the bumps, this is the one to look at.

Dreame AirStyle Pro: the tool to style them with

Any hot air brush works with the steps above. If you are buying one for extensions, the AirStyle Pro is a good fit. It has seven magnetic attachments, including a round volumizing brush, two smoothing brushes and two 32mm auto-wrap barrels. Dreame lists three heat settings, the top one about 176°F, plus a cool setting.

That moderate top heat suits extensions, and the cool setting sets the shape. Some reviewers say the attachments do not always click on securely, so press them home before you start. For more options, see our guide to the best hot air brushes for fine hair.

Comparison at a glance

Mistakes that make extensions look fake

• Different ends. Curling the extensions but leaving your own hair straight. Style every section the same way.
• Too much heat. High heat dries extensions fast, and the ends turn frizzy and dull. Once they are damaged, conditioner will not bring them back.
• Brush at the clips. Starting the brush at the scalp snags the clips and can pull a weft loose. Start a few inches down.
• The wrong weight. Long, light sets on thick hair leave thin, see-through ends. Match the grams to your hair.
• Clips too close to your part. If you can see a clip when you move your head, move the top weft down half an inch.

Caring for heat-styled extensions

Extensions need more care than your own hair, because nothing replaces the oil they lose. Brush them gently from the ends up with a loop or paddle brush. Wash them only when they need it, not every time you wash your hair. LaaVoo's care tips also say to make sure your hair is dry before you brush or sleep, and to braid it at night.

Store them flat or hung, out of the sun, in the bag or box they came in. Wefts that are crushed in a drawer get kinks that take extra heat to remove.

If your own hair is thinning or breaking under the clips, take a break from extensions and talk to a stylist or dermatologist.

Which set should you buy?

New to clip-ins, with fine to medium hair: the LaaVoo 7-piece Remy set. You want them to lie flat and blend without a high price: the Vivien PU Genius set. You want the most invisible weft and do not mind paying more: the LaaVoo Injection PU set.

Whatever you pick, style it with low heat and a cool shot, and it will last much longer. If you are also choosing a flat iron for straight looks, see our guide to ceramic vs titanium flat irons.
