  • Separating is best. The easiest way is to straighten your extensions separate from your natural hair. Unclip, wash, fully air dry, then straighten each weft slowly on low heat.

  • Layer It Up. If straightening together with your own hair, detangle everything first. Then straighten in layers from the bottom up, using a heat protectant.

  • Blow It Out. You can also blow dry extensions straight after washing. Apply a smoothing cream, brush through, and use a round brush while blow drying on cool.

  • Take It Easy. No matter which method you use, always go slowly and be gentle. Using too much heat can make extensions dry, frizzy and worn out fast.

Can You Straighten Hair Extensions?

You can definitely straighten those extensions, but be careful not to damage them. Use a low heat setting around 250°F/120°C when straightening - high heat can make extensions wear out fast and even start loosening over time.

The easiest way is to straighten extensions separately from your natural hair. Unclip them, wash, let fully air dry, and brush out tangles. Spritz with a heat protectant, then straighten each weft on low heat going top to bottom.

If straightening extensions with your own hair, detangle everything first and use a thermal protectant. Straighten in layers, starting on the bottom sections. Go slowly, straightening in small sections until it's all smooth.

Types of Hair Extensions

Hair extensions come in two main categories: real human hair and synthetic hair.

Remy hair extensions are made from actual human hair collected from donors. "Remy" hair means the outer cuticle layer is kept intact and runs in the same direction, resulting in smooth, tangle-free extensions.

Synthetic hair extensions are made from fine, blended fibers designed to mimic real hair. They don't contain any human hair.

Common extension types include:

  1. Clip-In Hair Extensions

  2. Tape-In Hair Extensions

  3. Microlink Hair Extensions

  4. Sew-In Weaves

  5. Keratin Bond Extensions

Tools Needed for Straightening Extensions

good quality flat iron or straightener

Taking good care of your hair extensions is super important if you want them look beautiful for a long time. Use special products made just for keratin and real human hair - when putting them in, styling, and storing. This protects your extensions and keeps them in beautiful shape. Now, straightening extensions needs the right tools.

  1. You need a good quality flat iron or straightener that doesn't get crazy hot. A ceramic one designed for styling hair extension is perfect. Using a cheap one or one that gets super hot can seriously mess up those beautiful extensions you paid good money for.

  2. You need a good heat protectant spray or serum. This stuff is key! It creates a barrier so the straightener's direct heat doesn't fry your extensions to a crisp. Look for one specifically made for extensions or real human hair.

  3. You gotta have some sectioning clips on hand. These let you clip up sections of hair while straightening, so you can get to all of it evenly without missing spots. Plus, it helps spread the heat out better instead of overcooking some hair strands.

Step-by-Step Guide to Straightening Extensions

Over time, it is possible to straighten hair extensions without losing the volume. You don’t have to worry about losing your quality texture when you have great extensions and methods to keep them bouncy.

Prepping the Extensions

Before straightening your curly hair extensions, you'll need to get them ready. Start by washing your extensions with a gentle shampoo and conditioner. Avoid anything too harsh - you want mild, hair-friendly products.

After rinsing out the products, pat your extensions dry with a towel. Let them air dry for around 20 minutes before breaking out the blow dryer.

Once they're partly dried, gently comb or brush through your curly extensions to get rid of any knots or tangles. This makes straightening a lot smoother. With the knots out and the extensions slightly damp and clean, you're ready to straighten.

But before using any hot tools, you absolutely must use a heat protectant spray or cream. This stuff is crucial for extensions and natural hair alike when you're applying high heat.

Make sure to get a good quality heat protectant that'll really do the job of shielding your hair.

Sectioning and Straightening

Okay, now that your extensions are prepped and ready, it's time to blow dry them. We like to blow dry while gently combing through because it helps reduce the heat we'll need for straightening. When blow drying, keep it on the cool setting and work from roots to ends, brushing as you go.

Take your time and keep at it until your extensions feel completely dry. It may seem like it's taking forever, but trust us, it's worth the effort. The less intense heat we use upfront, the easier it'll be to revive those gorgeous volumes later.

Once they're dry, grab your straightener and start with the lowest heat setting possible. Yes, it'll take longer this way, but you'll thank us later for babying those luscious locks. As we straighten, work in manageable sections – this keeps things neat.

Methodically straighten one section at a time until it's silky smooth, using a light hand with any styling products. If you're in a rush, we can carefully bump up the heat, but don't go crazy. Slow and steady is the way to minimize damage.

Tips for Avoiding Damage

  1. Prep Properly

  • Start with clean, well-conditioned hair that's hydrated and detangled

  • Use a heat protective spray to create a barrier against hot tools

  • For curly hair, use a leave-in conditioner or smoothing serum to tame frizz and add extra protection

  1. Invest in Quality Tools

  • Get a ceramic or tourmaline flat iron that distributes heat evenly

  • Choose one with adjustable temperature settings to customize the heat level

  • Work in thin sections, gliding the iron smoothly from roots to ends

  1. Straighten Strategically

  • Take it slow - don't go over the same sections repeatedly

  • Use one smooth stroke of the flat iron to avoid excess heat exposure

  • Gentle technique prevents damage and crispy, fried locks

  1. Maintain With Care

  • Apply a lightweight hair oil or serum to seal in moisture after straightening

  • Wrap hair in a silk/satin scarf or use a silk pillowcase at night

  • This prevents frizz, reduces friction, and locks in a sleek style

  1. Limit Heat Exposure

  • Incorporate heat-free styling days into your routine

  • The less frequent use of hot tools, the healthier your hair

  • Preparation and proper technique allow straightening with minimal damage

Aftercare for Straight Extensions

After getting your hair straightened and using hot tools, it's important to give your wavy hair extensions a break. Proper aftercare is key to keeping those gorgeous straight extensions looking fabulous for as long as possible.

Wash. When it's time for a good scrub, use the shampoo and conditioner products recommended by your stylist. Focus the shampoo on your roots and the conditioner on the ends. Avoid anything with harsh sulfates or alcohol, as those can cause tangling and matting - not a cute look!

Drying. Never, ever go to bed with wet extensions. Damp hair is a recipe for knots and matting galore. Always make sure your extensions are completely dry before going to sleep.

Brushing. Use a good quality brush made for extensions and start at the ends, working your way up slowly. This minimizes tugging and breakage on both your extensions and your real hair.

High quality products. Stick to sulfate-free, paraben-free shampoos, hair smoothing serum, and conditioners. These will keep your extensions hydrated and maintain that brilliant shine.

Hydration. Be sure to use hydrating hair masks and daily serums or oils, especially if your extensions are chemically-treated. This stops them from drying out.

Chlorine and saltwater are public enemies #1 and #2 for extensions. Both can cause extreme dryness and damage. If you're hitting the pool or beach, rinse with plain tap water and use a leave-in conditioner first as protection.

Proper storage in a satin pouch or pillowcase will help keep your extensions tame until next time.
