Choosing Your Hair Extensions Length

  • You Asked...
Choosing Your Hair Extensions Length

Want a glow-up that turns heads? Extensions are your shortcut to instant volume, and length. But the secret to looking effortlessly glam? Picking the right length. Whether you’re after subtle bounce or mermaid style locks, this guide breaks down everything you need to know. Quick, clear, and confidence-boosting.

What Hair Extension Lengths Can I Choose From?

Extensions come in standard lengths, measured in inches. Ours? A luxe variety from 10" to 30" in 100% human hair. Translation: whatever your vibe, a bob with volume, shoulder-grazing with length, or Rapunzel-realness, we’ve got it.

Check out our collections page where you can filter by length and type. Easy. Efficient. Stylish.

Not sure which method works best for your hair type? Whether you’re fine-haired or thick-maned, there’s an option to suit. Dive into our blog ‘Which Remi Cachet Hair Extensions Should I Buy?’ for the full breakdown.

Finding The Perfect Hair Extension Length For Your Style

Extensions aren’t one-size-fits-all. Too much length or weight can put strain on your natural hair. That’s why we always recommend a professional consultation. Your stylist will guide you to lengths that are safe, stylish, and flawless.

Length Based On Starting Hair Type

Your starting length matters. If you’ve got a bob cut, super-long extensions won’t blend naturally. The golden rule? Keep your extensions within 3–4 inches of your own hair.

How Long Does Your Hair Need To Be For Extensions?

Your natural hair should be at least 4–6 inches (10–15 cm) long before adding extensions. This length gives enough grip for secure attachment and keeps the joins hidden, so your finished look stays natural, seamless, and sleek.

Does Extension Type Affect Length Choice?

Absolutely. Different methods = different possibilities.

  • Clip In Hair Extensions: Flexible, fast, and friendly to many lengths. Perfect for playing with different looks. 

    Available in; 16”, 18”, 20”, 22” and 24”. 

  • Tape Hair Extensions: Super versatile and suitable for a huge variety of lengths. With the wide range we offer, they blend seamlessly and deliver that mane character energy finish every time. 

    Available in; 10”, 14”, 16”, 18”, 20” and 22”.

  • Weft Hair Extensions: Perfect for adding serious volume to thicker hair or boosting length. While they’re a go-to for long styles, they’re also available in shorter lengths so you can still turn up the fullness without mermaid vibes.

    Available in; 12”, 16”, 18”, 20”, 22”, 24” and 30”.

  • Pre-Bonded Hair Extensions: Discreet, durable, and designed to last. These methods work beautifully across a range of lengths, giving you a natural blend and long-lasting finish without compromising comfort.

    Available in; 12”, 16”, 18”, 20”, 22” and 24”.

Pick A Length That Matches Your Hair Goals

Your hair dreams = your length choice.

  • Shorter extensions: Perfect for boosting volume without changing your overall length. Subtle but stunning.

  • Layered lengths: Mix lengths for dimension and movement. Adds texture, depth, and instant interest.

  • Dream hair goals: Want a big transformation? Choose lengths that help you nail your vision, whether that’s volume for bouncy blow-dries or long, sleek sophistication.

  • Special occasions: Go long and dramatic for weddings, parties, or other events. Big hair, big impact, without the long-term commitment.

How To Measure Your Hair For Extensions

Grab a tape measure. Place it an inch above your ear and measure down to your ends. That’s your baseline.

General rule: an example is if your hair is 16", go for 18–20" extensions. Smooth blend, manageable length, and no harsh jump. But always book a consultation, your stylist will check if your hair is strong enough to handle the weights the various lengths come in.
