How Long Do Sew in Hair Extensions Last?

The durability of sew-in hair extensions can vary depending on several factors, including the quality of the hair extensions, the installation technique, maintenance practices, and individual factors such as hair growth rate and lifestyle. Generally, sew-in hair extensions can last anywhere from 6 to 8 weeks, but with proper care, they can potentially last up to 10 weeks or even longer.

It's true that sew-in hair extensions may have a slightly shorter lifespan compared to other types of permanent extensions. However, they remain highly favored among individuals seeking hair extensions due to the numerous benefits they offer.

What Factors Impact The Lifespan of Sew-in Hair Extensions?

Knowing the factors that impact the lifespan of sew-in hair extensions is important for several reasons:

Hair Growth

Hair extensions can be a fantastic way to add length and volume to your natural hair. However, there is a common concern for individuals who enjoy the benefits of hair extensions but also experience rapid hair growth. Women whose hair growth rate is higher than normal people may suffer discomfort or potential damage because their extensions become too loose or tangled sooner.

If you find yourself constantly needing touch-ups due to fast hair growth, don't worry! It simply means that your luscious locks are flourishing.

Quality of Sew-in Hair

The quality of hair plays such an important role in the longevity of sew-in hair extensions. There are two main types of materials used to make sew-in hair extensions: human hair and synthetic fiber. Each of them has different advantages but for a longer lifespan, people usually choose sew-in weft made of human hair instead of the synthetic one.

Nowadays, More and more hair suppliers tend to blend synthetic fibers with human hair to take more benefit. To prevent buying low-quality hair extensions, you should buy from trusted vendors with many years in the market such as Mic Hair or Bellami.

Stylist Skill and Experience

There is no denying the importance of skill and experience of hair stylists in getting sew-in extensions done perfectly. A skilled stylist with years of experience under their belt will know how to do the installation process in the right way. They have honed their techniques and developed an eye for detail that allows them to understand clients' needs and deliver exceptional results.

Styling Habit and Maintenance

On the other hand, an inexperienced stylist without a solid foundation of knowledge and hands-on practice may struggle with complex steps and fail to get your sew-in done perfectly.

The durability of sew-in hair extensions depends on how well you protect your sew-in hair extensions during activities and how proper care you do. Regular maintenance is essential to keep your sew-in hair extensions looking their best. By following a consistent maintenance routine, you can prevent tangling, matting, and other issues that can shorten the lifespan of your extensions.

Tips to Make Your Sew in Hair Extensions Last Longer

Wrap Your Hair When Going to Bed

Sleeping without protecting your sew-in hair extensions can lead to tangling and damage. To prevent this, cover your head with a satin bonnet, hair wrap, or scarf before going to bed. These materials help to minimize friction and keep your hair securely in place, ensuring that your extensions remain tangle-free.

Regularly Wash Your Hair

Maintaining clean hair is crucial in prolonging the lifespan of your sew-in hair extensions. Washing your hair at least once every two weeks will help remove any built-up dirt, oils, or product residue that can weigh down your extensions. Focus on gently washing the roots while paying extra attention to the ends, as they tend to be more prone to dryness.

Apply a Heat Protectant

Using heat styling tools without proper protection can cause irreversible damage to your sew-in hair extensions. Before blow-drying, flat ironing, curling, or using any heat tools, it's essential to apply a heat protectant to your hair. This will create a barrier between the hair and the heat, minimizing the risk of heat-related damage and preserving the quality of your extensions.

Apply a Heat Protectant

Wearing a Swimming Cap

Chlorine in pools can be detrimental to both your natural hair and sew-in extensions. To protect your extensions while swimming, it is advisable to wear a swim cap. The swim cap acts as a barrier, preventing direct exposure to chlorinated water, which can strip moisture from the hair and cause dryness and tangling.

Moisturizing and Deep Conditioning

Sew-in hair extensions, like other types of extensions, do not receive moisture from the scalp. Therefore, it is crucial to provide sufficient moisture to keep them healthy and prolong their lifespan. Use a moisturizing and deep conditioning treatment regularly to lock in moisture and prevent the hair from becoming dry and brittle. Focus on applying these products to the mid-lengths and ends, as they are more susceptible to dryness.

Moisturizing and Deep Conditioning

Final Thoughts

In conclusion, the lifespan of sew-in hair extensions can be extended with proper care and maintenance. Factors such as hair growth, the quality of the extensions, the skill and experience of the stylist, and maintenance routines all play a crucial role in determining how long your sew-in hair extensions will last.

By following the tips I mentioned in this post - wrapping your hair at bedtime, regularly washing your hair, using a heat protectant, protecting your extensions while swimming, and moisturizing and deep conditioning - you can maximize the longevity of your sew-in hair extensions and keep them looking beautiful for an extended period.
