Direct answer: To recreate Rumi’s hair with extensions, follow a beginner- friendly step-by-step braid method that adds extensions for length and volume while keeping the look neat and cosplay-ready. What you’ll need

• A pack of hair extensions in the color closest to your natural hair or Rumi’s signature purple if you’re aiming for the exact look.
• Small clear hair elastics, a few hair pins, and optional braid cuffs or rings for a finished touch.
• A crochet hook or a fine-tiber tail comb to help thread extensions, if you’re using micro-link or clip-in extensions.

Step-by-step guide

1. Prepare and section

• Start with clean, dry hair. Brush thoroughly to remove tangles.
• Part your hair to create a clean crown line for a centered look. You’ll be building a long, prominent braid from the crown down to the nape.

2. Attach extensions

• If using clip-in extensions, clip in along the crown and sides to add bulk where the braid begins. If using loose extensions with a crochet method, attach them gradually, ensuring even distribution to avoid bulk at the root.
• Secure the extensions with small elastics or by weaving them into the existing hair as you go, aiming for a seamless blend with your natural hair.

3. Create the base braid

• Start with a three-strand braid at the top portion of the crown. Keep the first few crossovers neat and tight to establish a clean shape.
• As you braid, periodically stretch the sides gently to create a fuller, more even look.

4. Integrate extensions for length and volume

• After the initial few crossovers, begin incorporating additional extension strands into the braid by adding a small amount of hair with each cross, similar to a French braid technique.
• Continue braiding downward, adding extensions evenly on both sides so the braid remains thick toward the ends.

5. Secure and finish

• Once you reach the desired length, secure the braid with a small elastic at the end.
• If desired, wrap a small strand of the natural hair around the elastic and secure with a bobby pin to conceal the band.
• Add a touch of hairspray to reduce flyaways, and optionally apply hair tinsel or decorative cuffs for a more dramatic look.

6. Optional adjustments

• If your hair is fine, you can backcomb lightly at the crown before braiding to create extra volume.
• For a more “Rumi” look, consider using a bold, vibrant extension color (like purple) and a slightly looser braid that still stays tidy at the crown.

Maintenance and tips

• Practice helps: start with a looser, longer braid and gradually tighten as you gain confidence.
• Use lightweight extensions to avoid weighing down fine hair; this keeps the braid from looking flat.
• If you’re new to extensions, consider a quick practice run with a cheap set to refine your braid technique before the final look.

If you’d like, I can tailor this to your hair length, thickness, and preferred extension type (clip-in, sew-in, or crochet), and suggest a precise sequence of section sizes and braid passes to match the exact Rumi-inspired silhouette you’re aiming for.
