The duration of a sew-in hair extension installation can vary depending on several factors, including the type of hair used, the quality of the installation, and how well the extensions are maintained. On average, a sew in can last anywhere from 6 to 8 weeks. However, some sew-ins can stay intact for up to 12 weeks with proper care. 

After the initial 6 to 8 weeks, the sew-in will start to loosen as the natural hair grows, and the tension on the braids may become uncomfortable. At this point, it is advisable to have the sew-in professionally removed or adjusted. It is not recommended to leave the sew-in in for an extended period, as it can lead to damage or breakage of the natural hair.

   1. Choose high-quality hair extensions

Investing in high-quality hair extensions is crucial for a longer-lasting sew-in. You should opt for human hair extensions, preferably virgin hair, as they tend to have better longevity and a more natural appearance. 

Moreover, we recommend searching for the best sew in hair extensions on the market. These products are crafted with 100% human hair, which are less prone to tangling and shedding.

   2. Seek professional installation

While it may be tempting to attempt a DIY sew-in, professional installation is highly recommended. An experienced stylist will ensure that the extensions are applied correctly, preventing damage to your natural hair and maximizing their longevity. A professional installation also guarantees a natural-looking result and reduces the risk of discomfort or tightness.

   3. Practice proper washing techniques

You should wash your extensions in every 7 to q0 days. When washing your hair, use a gentle, sulfate-free shampoo and conditioner specifically designed for hair extensions. Don’t forget to avoid applying excessive force or rubbing the extensions vigorously. Instead, you should gently massage the products into your scalp and rinse thoroughly.

   4. Follow a regular maintenance routine

Establishing a regular maintenance routine is key to extending the life of your sew in. First, you need to develop a nightly routine that involves wrapping your hair in a silk or satin scarf or using a silk pillowcase to prevent friction and minimize tangles. Additionally, avoid excessive heat styling, as it can damage the hair extensions. What’s more? Remember to opt for heat-free styles or use a heat protectant spray if styling with hot tools is necessary.

   5. Protect your hair during physical activities

To avoid damage and breakage, tie your hair in a low ponytail or braid before exercising to minimize movement and friction. Tight hair accessories should be avoided as they can cause tension and breakage to your natural hair.

When planning to swim, it is important to be extra cautious and protect your sew in from the damaging effects of chlorine and saltwater. Wearing a swim cap or applying a leave-in conditioner can create a protective barrier between your hair and the water. After swimming, rinse your hair with clean water and apply a moisturizing conditioner to restore hydration and prevent tangling.

Sleeping on a cotton pillowcase can cause friction and tangles, leading to damage and a shorter lifespan for your sew in. To prevent this, our hair experts suggest using a silk or satin pillowcase, or wrapping your hair in a silk or satin scarf to reduce friction and prevent tangling.


   1. Does a sew in last longer than a wig?

Both sew-ins and wigs have their own lifespan. While a sew in can last several weeks to a few months, a wig typically lasts around 3 to 6 months with proper care. The durability of both options depends on various factors, including the quality of the hair, maintenance routine, and individual hair growth rate.

   2. How do you maintain a sew-in?

To maintain a sew-in hair extension, follow these steps:

  • Wash and condition the hair regularly with sulfate-free products.
  • Use a wide-tooth comb or a brush specifically designed for extensions to detangle gently.
  • Avoid excessive heat styling and use a heat protectant when styling.
  • Wrap the hair at night with a satin scarf or bonnet to prevent tangling and friction.
