Getting sew in hair extensions can be a great way to change your look, add volume, or grow out your natural hair. But just like natural hair, extensions need care and attention to stay looking their best. As a hair extension specialist, I’ve seen many clients come in with sew-ins that could have lasted longer — if they had known the right maintenance steps. So today, I’m sharing my top tips to help you keep your sew-in looking fresh and fabulous for as long as possible.
1. Choose the Right Hair and Installation Method
Before we even talk about maintenance, it’s important to make sure you start with quality. Not all hair extensions are the same. If you’re visiting a sew in hair extensions salon, ask your stylist what type of hair they recommend. Virgin or 100% human hair usually lasts longer and looks more natural than synthetic options.
Also, make sure your sew-in is installed correctly. A hair extension specialist will braid your natural hair in a way that lays flat and secure, which helps your sew-in last longer and feel more comfortable. A good foundation is key to making your extensions look great.
2. Don’t Skip the Nighttime Routine
One of the easiest ways to protect your sew-in is by wrapping your hair before bed. Use a silk or satin scarf or bonnet. This helps prevent frizz, tangles, and dryness. Cotton pillowcases can pull moisture from your hair, causing it to look dull. So, switching to a satin pillowcase can also help.
If you have longer extensions, you might want to braid them or put them in a loose ponytail at night. This keeps the hair from getting matted while you sleep.
3. Keep Your Scalp Clean
Just because your natural hair is braided underneath doesn’t mean you can forget about it. Your scalp still needs care. Use a gentle, sulfate-free shampoo to cleanse your scalp. You can do this by applying the shampoo with a nozzle bottle or spraying diluted shampoo between your tracks.
Focus on getting your scalp clean without disturbing the braids. After rinsing, gently pat the sew-in dry with a towel. Don’t rub or twist the hair. If you’re not sure how to wash it properly, ask your hair extension specialist for help — many salons offer wash and maintenance services for sew-ins.
4. Moisturize, But Don’t Overdo It
Just like your natural hair, extensions need moisture. Use a light leave-in conditioner or hair oil to keep your extensions shiny and soft. Apply the product from the mid-shaft to the ends — avoid putting heavy oils on the roots or the braids underneath, as this can cause buildup or mildew.
If your scalp feels dry or itchy, you can use a light scalp oil or soothing spray. Just be careful not to use too much, or your hair may start to feel greasy or weighed down.
5. Avoid Heat Damage
Heat styling tools like flat irons, curling wands, or blow dryers can be used on sew-in extensions, but always with caution. Use a heat protectant spray before applying any heat. Try not to use hot tools more than a couple of times per week.
If you can, go for heatless styling methods like flexi rods, bantu knots, or braiding the hair for waves. These styles are not only healthier for your hair, but they also help your sew-in last longer.
6. Limit Product Buildup
Too much product can make your extensions heavy, sticky, or dull. It can also cause your scalp to get itchy or irritated. Try to use lightweight products and apply only what you need. Washing your sew-in every 2–3 weeks helps keep the hair clean and refreshed.
If you’re someone who uses edge control or styling gels often, make sure to clean your edges regularly so the buildup doesn’t spread into your sew-in.
7. Visit the Salon for Regular Maintenance
Even if you take great care of your sew-in at home, nothing beats professional care. A visit to a sew in hair extensions salon every 2–3 weeks can help your stylist check on the condition of your hair and make any adjustments. They can tighten loose tracks, cleanse your scalp, and trim your extensions if needed.
As a hair extension specialist, I always tell my clients that regular salon visits help extend the life of the install and protect your natural hair underneath.
8. Know When It’s Time to Take It Out
Sew-ins are not meant to stay in forever. A good rule is to wear your sew-in for no more than 6–8 weeks. Leaving it in longer can cause your natural hair to become matted, break off, or even start to smell due to moisture and product buildup.
When it’s time to remove your sew-in, visit your sew in hair extensions salon so a professional can take it out safely. Don’t try to cut it out at home, as you might accidentally cut your hair.
After removal, give your hair a break. Deep condition your natural hair, trim your ends, and let your scalp breathe before installing a new set of extensions.
9. Choose Protective Styles Between Sew-Ins
If you’re someone who wears sew-ins back-to-back, consider giving your natural hair a break in between installs. Wearing your hair in a bun, twist-out, or braids without extensions allows your scalp to rest and helps prevent tension or damage.
Talk to your hair extension specialist about a healthy styling schedule that gives your hair time to recover between sew-ins.
10. Listen to Your Hair
Every person’s hair is different. If something doesn’t feel right — if your scalp is too tight, your extensions feel heavy, or your hair starts shedding — don’t ignore it. Talk to your stylist right away.
A good sew-in hair extensions salon will always be happy to check on your install and offer advice. Your stylist should be your partner in keeping both your extensions and your natural hair in great shape.
Final Thoughts
Sew-in hair extensions can give you a beautiful, versatile look, but they also require regular care. By following these maintenance tips, you can keep your sew-in looking fresh and your natural hair healthy underneath.
Whether you’re new to sew-ins or a long-time extension lover, working with a trusted hair extension specialist makes all the difference. Don’t hesitate to ask questions, schedule regular salon visits, and invest in good hair care products. The better you care for your extensions, the better they’ll look — and the longer they’ll last.
