Hair extensions aren’t just about length — they’re about versatility, protection, and style. Two of the most popular methods in 2025 are the classic sew-in weave and the modern micro-link installation. But what exactly are they, and which might be right for you? Let’s break it down.

✂️ What a Sew-In Weave Actually Is

You’ve probably heard people say, “I got a weave,” but what does that mean?

A sew-in weave (or weave-on) is a protective style where your natural hair is braided into cornrows and extension hair is sewn onto the braids using a needle and thread.

Why it works:

• Protective → your natural hair is tucked away and shielded from daily manipulation.
• Versatile → you can go long, short, curly, straight, or even switch up colors without dyeing your real hair.
• Long-lasting → with good care, a sew-in can last 6–8 weeks.

Things to know:

• Your scalp still needs care: oil, cleanse, and moisturize the braids underneath.
• It’s best to take breaks between sew-ins to avoid tension and keep your natural hair healthy.
• Sew-ins can be styled like your own hair, but avoid too much heat to protect both your natural hair and the extensions.

🔗 How Micro-Links Work (and Why They’re Trending)

Micro-links (also called micro-beads or I-tip extensions) are a strand-by-strand extension method that doesn’t use glue or thread. Instead, small silicone-lined beads are used to attach tiny bundles of extension hair to your natural hair.

Why people love them:

• No braids, no thread, no glue → it’s a lightweight, natural-looking method.
• Free movement → unlike sew-ins, your scalp is more accessible, and the extensions move like natural hair.
• Customizable → you can add volume in specific areas or blend different textures easily.
