40 Inch Human Hair Extensions Price Guide for Premium Length

When it comes to making a statement, nothing speaks louder than extra-long, flowing locks. 40 inch human hair extensions are the epitome of luxury in the beauty and hair industry. Reserved for bold trendsetters, red carpet looks, or high-fashion shoots, these extensions exude glamour, length, and confidence.

But how much does it really cost to own or offer 40-inch extensions? What should you expect in terms of quality, sourcing, installation, and maintenance? In this detailed guide, we break down everything you need to know about premium 40” hair extensions – including types, pricing, quality indicators, and expert tips to help you choose the right supplier.

Why 40-Inch Human Hair Extensions Are So Coveted

1.1 The Ultimate Length for Maximum Impact

40-inch extensions fall well past the waist and often reach the upper thighs on most individuals. They deliver:

• Dramatic, show-stopping looks

• Perfect styling flexibility for braids, ponytails, or layered waves

• High demand in runway, bridal, influencer, and music video industries

1.2 Rare and Premium

Not all hair donors grow their hair to 40 inches. That’s why long strands this size are rare and more expensive, especially in raw and unprocessed form. Every inch past 30” increases the value significantly.

Types of 40-Inch Human Hair Extensions

When shopping for this luxurious length, you’ll find a few different formats:

2.1 Weft Bundles

• Sew-in hair in machine or hand-tied wefts

• Typically sold in 100g (3.5 oz) bundles

• You may need 4–5 bundles for a full install at 40 inches

2.2 Wigs (Frontal & Closure)

• Ready-to-wear options with pre-attached lace

• Closure wigs are easier to maintain; frontals offer natural hairlines

• HD lace 40” wigs are the highest priced and most natural-looking

2.3 Tape-In or Keratin Tip

• Less common at this length due to potential slippage

• Ideal only for temporary show looks

2.4 Clip-Ins

• Temporary solutions, often customized by stylists

• Need proper weight and volume to balance the long length

How to Spot Real Premium 40-Inch Hair

✅ The Cuticle Test

Run your fingers along the strands — premium raw hair will feel smooth in both directions and tangle minimally.

✅ Color Consistency

High-quality raw hair comes in natural black or brown, not overly shiny or jet black unless dyed.

✅ Ends Matter

Inspect the tips of 40-inch hair. Good suppliers use full, healthy ends, not thinned-out or dry ones.

✅ Weight Check

One bundle must weigh around 100g (3.5 oz). For 40”, thinner bundles are common but not ideal. Avoid underweight bundles.

Tips for Buying 40 Inch Human Hair Extensions in Bulk

6.1 Always Ask for Videos & Photos

• Request real product images and length verification from the vendor

• Avoid stock photos or overly edited pics

6.2 Start With a Sample Order

Before placing a large order, test:

• Texture

• Shedding/tangling resistance

• Dyeability and heat tolerance

6.3 Verify the Vendor

Use platforms like:

• WhatsApp video calls

• Facebook/Instagram pages with tagged reviews

• YouTube unboxings

• Google Business Reviews

Maintenance Tips for 40 Inch Human Hair Extensions

Due to the extreme length, this hair requires extra care:

• Use sulfate-free shampoo and deep conditioner weekly

• Always detangle from ends to root with a wide-tooth comb

• Braid or wrap the hair before sleep

• Avoid heat tools daily – use heat protectant if needed

• Professional styling and tightening every 4–6 weeks
