What Is Sew-in Weft Extensions?
Sew-in extensions, or weft extensions, are a type of permanent hair extension. A professional stylist applies them by sewing the weft onto pre-braided hair or micro-beads. The sew-in options include Hand-tied, Genius, Flat, and Machine Wefts. They don’t need glue or heat, making them a safe choice for adding length and volume. Sew-ins blend well with natural hair, giving a full, layered look. They also protect your hair from heat damage, keeping it healthy.
Flexible installs with sew-in or bead methods.
Quick removal in minutes, no adhesive needed.
No glue or heat, safe for all hair types.

FAQs
Can I wash my hair with sew-in extensions?
Yes, you can wash sew-in extensions. Wash them 2–3 times a week and follow these steps:
- Use sulfate-free shampoo and conditioner only.
- Dry your hair right after washing, but avoid high heat to protect the weft base.
- After drying, apply hair oil to keep your natural hair and extensions smooth and shiny.
Can you swim with sew-in hair extensions?
Yes, you can swim with sew-in extensions, but you should wash your hair as soon as possible afterward. Pool water has chlorine, but sea or lake water has salts and minerals that can stay on your hair. After swimming:
- Rinse thoroughly with clean water.
- Dry your hair immediately, avoiding high heat.
- Before swimming, apply hair oil for protection, and wearing a swim cap is also a good option.
Are sew-in hair extensions damaging to natural hair?
No. If a professional stylist installs and maintains sew-in extensions, they won’t harm your natural hair. Follow your stylist’s advice. Wash your hair regularly and visit the salon every 6–8 weeks for maintenance and adjustments.
Can sew-in hair extensions be styled like other styles?
Yes. You can style them into ponytails, buns, or half-up-half-down looks. If you use curling irons or straighteners, always apply a heat protectant spray. Avoid high temperatures because excessive heat can damage PU-sealed bases like Genius or Flat Weft.
How long do sew-in hair extensions last?
Sew-in extensions typically last 6–8 weeks. With good care, they can last up to 12 weeks. Since the extensions are sewn in fixed microbeads, they move down as your natural hair grows. After 6–8 weeks, you can visit the salon to have them moved up if they’re still in good shape. The sew-in hair can last over a year with proper maintenance.
How much do sew-in hair extensions cost?
Installation usually costs $200 to $800. Hair wefts range from $100 to $300. Total costs depend on the type of sew-in extensions, installation method, color, length, time, and stylist. Typically, handmade extensions are pricier. For example:
Hand-tied> Genius Weft> Flat Weft> Machine Weft
Why can’t I place an order online?
Why can’t I see prices, and how can I get a quote?
Is there a minimum order quantity?
Yes. For in-stock Genius Weft, the MOQ is 50g. For custom orders, the MOQ is 100g. Both options give you access to wholesale pricing.
Are samples really free?
Yes, our samples are free for licensed hairstylists. Every sample kit includes at least 3 types of extensions so you can test quality and find the right fit. If your country charges import duties, these need to be covered on your side.
What color should I choose, and can you help me match it?
We offer dozens of extension colors and provide free color matching. Just send us 3 clear photos, and our experts will help you find the best shade for a seamless blend.
How long does it take to get my order, including custom orders?
In-stock products ship the same day after payment. Delivery times:- North America: 2–4 days
- Europe: 4–7 days
- Australia: 4–7 days
Custom orders need 7–20 days for production, depending on quantity.What are your shipping options?
