Your sew-in looked flawless when you first left the salon — full, shiny, and perfectly blended length to length. But as the weeks go by, you might notice changes: your hair feels heavier, your scalp gets a little itchy, or that silky movement isn’t quite the same. Don’t worry — it doesn’t mean you’re doing anything wrong! Like natural hair, sew-in extensions have a lifespan, and knowing when to replace sew-in extensions keeps your style healthy and beautiful.
Here are five clear signs it’s time to give your sew-in extensions a well-deserved refresh.
1. Loose or Slipping Extensions — The First Sign to Replace Your Sew-In Extensions
One of the first signs your sew-in is ready for a change is when it starts to feel loose or slips away from your scalp.
As your natural hair grows, the braids holding your sew-in weave extensions begin to loosen. That can cause uneven weight and scalp tension — and even pull on your real hair.
Pro tip: If you feel your sew-in “hanging” instead of laying flat, it’s time for a reinstall. On average, sew-ins should be replaced every 6 to 8 weeks for a secure, natural-looking fit from length to length.
2. You’re Noticing Tangling, Shedding, or Matting
When brushing becomes a battle, it’s a clear sign your extensions need attention. Over time, sew-in hair extensions collect product buildup, oil, and tangles that are tough to manage — especially near the wefts.
Even premium Russian hair extensions can lose their soft, silky texture if worn too long or not cared for properly. For tips on keeping your extensions smooth and long-lasting, check out our blog on what makes Russian hair extensions special.
What to do: If detangling takes forever or you’re shedding more than usual, it’s time to remove your sew-in, deep-clean your natural hair, and prepare for a fresh install using 100% Russian human hair for a smoother, more natural blend.
3. Your Scalp Feels Itchy, Tight, or Irritated
A healthy scalp is key to healthy hair. If yours feels itchy, tight, or irritated, it might be time for a break.
After several weeks, oils and sweat build up under the wefts, preventing your scalp from breathing properly. That can lead to discomfort — or even mild irritation if ignored.
Pay attention: If washing doesn’t ease the irritation, take your extensions out. A clean scalp will help your next sew-in — especially when using Russian hair extensions — feel lighter and look fresher.
4. The Extensions Have Lost Their Shine and Softness
When your sew-in no longer feels soft or shiny no matter how much conditioner you use, it’s a sure sign it’s time for replacement.
Over time, styling tools, sun exposure, and product buildup can dull the shine of your hair. While deep conditioning may help for a while, once the hair becomes dry or brittle, it’s best to refresh it.
Tip: Investing in high-quality Russian hair makes a huge difference. Because it’s naturally silky and aligned length to length, it moves like your real hair and maintains its luster longer — even after multiple installs. You can explore our Weft Hair Extensions collection to find salon-grade options perfect for your next sew-in.
5. It’s Been Over 8 Weeks Since Your Last Install
Even if your sew-in still looks okay, leaving it in too long can cause matting and buildup at the roots. Your natural hair continues to grow, which can make your extensions feel heavy and difficult to maintain.
Rule of thumb: Replace your sew-in hair extensions every 6–8 weeks to protect your real hair and keep your weave looking fresh. This not only maintains the perfect length to length balance but also keeps your scalp healthy.
Bonus: How to Make Your Next Sew-In Last Longer
When you care for your extensions properly, your Russian hair weave can be reused multiple times, saving you money while keeping your style fresh. Here’s some tips on how to make your next install look flawless for weeks:
- Use sulfate-free shampoo and lightweight conditioner every 1–2 weeks.
- Always dry your hair completely to avoid tangling.
- Wrap your hair in silk or satin before bed.
- Use a heat protectant when styling.
- Moisturize your scalp lightly to prevent dryness.
Final Thoughts
Your sew-in extensions are more than just hair, they’re part of your confidence. But even the best Russian hair extensions need a little maintenance and timely replacement to stay flawless.
By spotting the signs early — slipping tracks, tangling, dryness, or scalp irritation — you’ll protect both your natural hair and your investment.
