How Many Bundles for Relax Hair Extensions Sew-In?

How many Relaxed Straight hair bundles come in a pack?

ONYC Relaxed Straight Hair Bundles are sold per bundle, not in pre-packaged sets. Each Sew-In Weft Bundle weighs approximately 3.5 ounces (100 grams). You can mix and match lengths to achieve your preferred style.

When deciding how many bundles you need for ONYC Relaxed Straight Hair Extensions, especially the Sew-In Weft Bundle, it’s important to consider the desired fullness, length, and whether you’re leaving out natural hair, using a closure, or going for a full head install. Unlike curly textures, relaxed hair extensions offer a sleek, straight look, which may require more bundles for a fuller appearance.

How many bundles do I need for a sew-in with leave-out?

For a sew-in with leave-out using relaxed hair extensions, 2 to 3 bundles are ideal for lengths up to 18 inches. For longer styles (20 inches and above), 3 to 4 bundles are recommended to maintain a smooth, voluminous finish.

How many bundles for a sew-in with closure?

Using a closure with your ONYC Relaxed Straight Hair Extensions Sew-In Weft Bundle? You’ll typically need 2 bundles for shorter lengths (10–14 inches) and 3 to 4 bundles for longer lengths (16–24 inches). ONYC® also provides matching relaxed hair closures to create a seamless blend with your bundles.

How many bundles for a full head install?

For a full head install with relaxed hair extensions and no leave out, the number of bundles needed depends on your desired length and volume:

  • 2 bundles for lengths 10–14 inches
  • 2–3 bundles for lengths 16–18 inches
  • 3–4 bundles for lengths 20–24 inches

Because straight textures like the ONYC Relaxed Straight Hair Extensions are less voluminous than curls, using an extra bundle helps create a fuller, more polished look.

How many bundles for a quick weave?

For a quick weave using ONYC Relaxed Straight Hair Extensions, 2 to 3 Sew-In Weft Bundles are typically enough, depending on the area of application and style. Since the bonding method provides flexibility, you can customize your look with ease while achieving sleek results.


⚠ Limited Restock Notice: Our Mongolian textured hair, especially the straight and curly textures, require careful raw material sourcing and extensive craftsmanship during production. Restocking can take 3 to 6 months—secure your preferred style now to avoid delays.

My Holy Grail Hair “I absolutely love ONYC Relaxed Hair! I’ve tried every other brand you can think of, but nothing compares. I don’t know how they create this texture, but it looks exactly like my own relaxed hair — thick yet soft to the touch. I can curl it, flat iron it, bleach it… honestly, I’ve abused this hair and it’s still holding up beautifully. If I did that to my real hair, it would have fallen out by now! My only complaint? It’s constantly SOLD OUT. The moment it restocks, I’m stocking up like crazy! — Review by Francesca

ABOUT ONYC Relaxed Collections

Introduced in 2007, ONYC Relaxed Hair Weft and our premium ONYC Cuticle Virgin Hair represent the pinnacle of high-quality hair extensions. Crafted entirely from 100% full-cuticle human hair and sourced from a single donor, often referred to as “ponytail hair,” these extensions are the epitome of pure luxury. With all cuticles intact, they are durable, reusable, and a truly worthwhile investment for achieving a flawless, natural look.

This ONYC's Best Sellers In Hair Extensions are available in two stunning textures: Relaxed-Perm and Light Relaxed-Perm, offering a perfect blend of natural appearance and effortless style.

ONYC Relaxed Perm: The Relaxed Straight Hair Extension texture is specifically designed to blend seamlessly with African American hair that has been chemically relaxed. These extensions provide a sleek, straight finish with a hint of coarseness and a low-luster appearance, adding both volume and a natural, polished look.

ONYC Light Relaxed: The Silk Press Hair Extensions are a softer alternative to the Relaxed version. Offering a finer and silkier texture, these extensions deliver a smooth, straight look that’s perfect for those with naturally softer or looser curl patterns or anyone seeking a more flowing and lightweight style.

Both options are expertly crafted to enhance your natural beauty while providing the versatility and durability you expect from ONYC Hair.

ONYC Relaxed Hair Weave Extensions Are Long-Lasting, Reusable, and Maintain Their Silky Texture!

Known for their flawless blend and luxurious feel, ONYC® Relaxed Hair Bundles are made with real virgin human hair designed to mimic the look and movement of relaxed African American hair. With the right care, these premium extensions deliver exceptional longevity, making them a smart and stylish investment.

✓ Long-Lasting with Proper Care

ONYC Relaxed Hair Extensions are made from premium cuticle-aligned Virgin Hair, offering outstanding longevity when maintained correctly. With proper care, these relaxed straight hair bundles can last up to 12 months or more. Many customers have reused the same bundles across multiple installs for up to 2 years—making them a worthwhile investment.

✓ Follow the Right Maintenance Routine

To extend the life of your relaxed hair weave, follow a consistent care regimen: gentle shampooing with sulfate-free products, regular conditioning, and minimal heat styling. This helps preserve the softness, sheen, and natural flow of the hair.

✓ Minimize Heat & Avoid Harsh Chemicals

Excessive heat or chemical treatments can shorten the lifespan of your extensions. Stick to low-heat styling tools when necessary, and always use a heat protectant to safeguard your real human hair bundles from dryness and breakage.

✓ Store and Handle with Care

Between installs, store your ONYC Relaxed Hair in a satin bag or original packaging. Keep the hair clean, dry, and tangle-free to maintain its full-bodied, natural-looking texture across multiple uses.

Handled with care, ONYC’s Relaxed Hair Extensions remain silky, voluminous, and tangle-free—providing the long-lasting quality and style retention ONYC is known for.

About ONYC Relaxed Hair Bundle Coloring –

Coloring your ONYC® Relaxed Hair Bundles is possible with care. Because our hair is made from 100% real human strands, it responds just like natural hair—giving you the flexibility to personalize your style while maintaining quality.

Yes — ONYC Relaxed Hair Extensions Can Be Safely Colored ✓

ONYC Relax Straight Hair Bundles are made from 100% Virgin Human Hair, which means they can be professionally colored just like your natural hair. We recommend consulting a stylist with experience in coloring relaxed straight human hair extensions for best results.

Choose Gentle Color Processes for Best Results ✓

While the hair can be dyed to darker or slightly lighter shades, avoid using overly harsh bleach or high-volume developers, as they can compromise the cuticle integrity and affect the smooth, sleek texture.

Coloring Will Alter Hair Structure Slightly ✓

Chemical coloring, even with care, may cause changes in softness and moisture retention. Since this is real virgin hair, it reacts like your own hair—so proper post-color maintenance is essential to keep your bundles healthy and long-lasting.

Always Perform a Strand Test Before Applying Color ✓

We strongly recommend having your stylist conduct a strand test before committing to full-bundle coloring. This helps gauge how the hair will respond and ensures a safe and predictable outcome.

Read Before You Color ✓

How to Dye Curly Weave – Best Hair Dye for Natural African American Hair

Yes — ONYC® Relaxed Hair Bundles Can Hold Curls Beautifully!

While ONYC® Relaxed Hair is designed to mimic the smooth, straight finish of relaxed African American hair, it also offers excellent versatility for styling. With proper heat styling tools and techniques, you can achieve soft waves, curls, or body with ease.

✓ Use the Right Tools for Long-Lasting Curls

To create and hold curls, we recommend using a quality curling wand or flexi rods on low to medium heat. Always apply a heat protectant to maintain the integrity of the real human hair and reduce heat damage.

✓ Curl Hold Depends on Texture

ONYC® offers various relaxed textures. While all our relaxed straight hair bundles can be curled, the ability to hold curls varies by type. Our Silk Press Hair Extensions are specifically designed to provide a soft, silky finish with enhanced styling flexibility—making them ideal for holding curls longer and with better bounce.

✓ Lock It In with Setting Products

To extend curl hold, set the hair using a lightweight styling mousse or curl-setting spray. Allow the curls to cool and set fully before combing or brushing for longer-lasting results.

Whether you're creating body curls, wand waves, or a voluminous look for a night out, ONYC® Relaxed Hair gives you the flexibility to switch up your style—while still maintaining a natural, salon-finished look.

How to Properly Care for Relaxed Hair Bundles:

ONYC® Relaxed Hair Bundles are made from premium Virgin Hair like Mongolian or Indian Remy Hair—crafted to mimic the look and feel of relaxed straight hair bundles for Black hair. With the right care routine, these high-quality hair extensions can maintain their soft, natural look and last for years.

Here’s how to keep your relaxed hair weave looking full-bodied, smooth, and flawless:

1. Gently Detangle Before and After Each Use

Always begin by using a wide-tooth comb or your fingers to gently detangle your ONYC® Relaxed Hair—starting from the ends and working your way up. This protects the cuticle-aligned human hair from breakage and preserves its tangle-free performance.

2. Cleanse Weekly with Sulfate-Free Shampoo

Wash your relaxed straight hair bundles weekly or bi-weekly with a moisturizing, sulfate-free shampoo to maintain their softness and sheen. Follow with a hydrating conditioner to lock in moisture and prevent dryness, especially if you heat-style frequently.

3. Air Dry Whenever Possible

To extend the lifespan of your Virgin Hair bundles, let them air dry after washing. If you must use a blow dryer, use a heat protectant and set it to low heat to avoid damaging the premium human hair fibers.

4. Wrap or Braid at Night

Preserve the sleekness of your relaxed hair weave by wrapping it with a satin or silk scarf before bed. Alternatively, braid or twist it loosely to prevent tangling and keep the hair smooth and manageable.

5. Minimize Heat Usage and Always Use a Protectant

Although ONYC® Hair mimics natural relaxed hair, limiting flat iron or curling wand use helps retain the natural luster and body of the bundles. Always apply a thermal protectant to reduce heat-related damage.

6. Deep Condition Monthly

Revitalize your straight ONYC® hair extensions with a deep conditioning treatment once a month. This is especially important for long relaxed weaves, helping them stay lightweight, voluminous, and full-bodied.

7. Store Properly Between Installs

When not in use, store your reusable ONYC bundles in a satin bag or box. Ensure they are clean, dry, and detangled to maintain their long-lasting quality.

Best Alternatives to ONYC Relaxed Straight Hair!

If your preferred ONYC Relaxed Straight Hair Bundle is temporarily sold out, you still have several excellent alternatives depending on how closely you want to match the original Relaxed Perm™ texture. Some options offer the exact same texture, while others give you a slightly silkier, finer, or fuller finish that can still achieve a very similar relaxed look.

1. Exact Texture Match – Relaxed Straight Lace Front Wig

If your priority is getting the exact ONYC Relaxed Perm™ texture, our Relaxed Straight Lace Front Wig is the closest alternative because it uses the same Relaxed Straight texture.

You may be wondering why we are recommending a wig when you normally buy bundles. Our Relaxed Straight wigs are customizable, and many ONYC customers have them sewn down just like a traditional sew-in. If you usually purchase bundles together with a closure, the wig can simplify your installation because the lace front and Relaxed Straight hair are already combined into one unit. If you want additional fullness, your stylist can also add compatible textured-straight hair underneath or between the wig tracks.

Best choice when: You want the exact Relaxed Straight texture and do not mind switching from bundles and a closure to a customizable sew-down wig.

Other Relaxed Straight installation options:

2. Slightly Silkier Alternative – Silk Press Silky Relaxed

If you do not mind going slightly silkier, try our Silk Press Silky Relaxed – Light Relaxed Perm™. This texture is smoother and sleeker than our classic Relaxed Perm™ hair, while still blending beautifully with relaxed or silk-pressed African American hair.

It is a great option for customers who love the Relaxed Straight look but would be comfortable with a slightly more polished and flowing finish.

Best choice when: You want a smoother, slightly silkier version of the Relaxed Straight look.

3. Very Close After Straightening – Kinky Straight ClassiQUE™

Our Kinky Straight ClassiQUE™ is another excellent alternative. Since its launch, it has quickly become one of our best-selling Kinky Straight Hair textures and now sells neck and neck with our long-time favorite Fro-Out™ Kinky Straight.

ClassiQUE™ has a finer, more refined texture than Fro-Out™, which allows it to straighten beautifully. Once properly flat-ironed, it can look very close to our Relaxed Straight texture while still maintaining natural-looking body and movement.

For existing ONYC customers who are used to the fuller ends and luxurious density of our premium collections, we especially recommend the Double Drawn Kinky Straight ClassiQUE™ option. The Double Drawn version gives you thicker density and fuller ends for a more substantial, luxury finish similar to the fullness you may already love from our Ultimate Collections.

Best choice when: You want a textured-straight option that straightens exceptionally well and can closely resemble Relaxed Straight. For fuller ends and more density, choose the Double Drawn ClassiQUE™ option.

4. Fuller Alternative – Fro-Out™ Kinky Straight

If you prefer more body and thickness, consider our Blow-Out Kinky Straight – Fro-Out™.

Fro-Out™ is thicker and more textured than Relaxed Straight because it is designed to resemble natural African American hair after being blow-dried rather than fully flat-ironed. However, it can also be straightened. When properly flat-ironed, especially in a less humid environment, Fro-Out™ can give you a smoother relaxed-inspired finish while maintaining more body and fullness.

Best choice when: You want more volume and density and do not mind straightening the hair for a smoother Relaxed Straight-inspired finish.

5. Another Similar Straight Texture – Light Yaki

Our Light Yaki Weave Bundles is also worth considering if you want a texture that sits close to Relaxed Straight.

ONYC Light Yaki is not like the extremely silky Light Yaki texture commonly found elsewhere. Ours has more substance and falls between our classic Relaxed Straight and our silkier Light Relaxed Perm™ texture, giving you a natural-looking straight finish without appearing overly silky.

This collection is Remy hair rather than the premium cuticle hair used in our higher-end collections, but it remains a high-quality option. Many ONYC customers have successfully reused their Yaki hair multiple times with proper care.

Best choice when: You want a similar textured-straight appearance and are comfortable choosing a quality Remy hair option.

Still Not Sure Which One to Choose?

For the exact Relaxed Straight texture, choose the Relaxed Straight Lace Front Wig.

For a slightly silkier and sleeker finish, choose the Silk Press Silky Relaxed – Light Relaxed Perm™.

For one of the closest looks after straightening, choose the Kinky Straight ClassiQUE™, especially the Double Drawn option if you prefer fuller ends.

For more fullness, body, and texture, choose the Fro-Out™ Kinky Straight.

For a textured-straight option that falls between Relaxed Straight and a silkier straight texture, consider the Light Yaki.

Does that mean I’ll have to wait that long from today for it to come back in stock? I really love this texture, but I need my hair sooner. Do you have another texture you would recommend as an alternative while I wait?
