How to Make Your Sew-In Last?

Choose High-Quality Hair Extensions

Investing in high-quality hair extensions significantly impacts the durability of your sew-in. Opt for virgin or remy hair, as these types of extensions tend to last longer and maintain their natural look and feel. Quality hair extensions are less prone to tangling and shedding, allowing your sew-in to withstand daily wear and tear.

Seek Professional Installation

Proper installation is crucial for the longevity of your sew-in. Choose a skilled and experienced stylist who can ensure secure attachment and minimize tension on your natural hair. The stylist should use appropriate braiding or sewing techniques to provide a solid foundation for the sew-in weave.

Establish a Maintenance Routine

Implementing a consistent maintenance routine is vital for extending the lifespan of your sew-in. Here are some key tips for maintaining sew in weave:

  • Wash Regularly: Cleanse your scalp and hair extensions using a sulfate-free shampoo. Gently massage the scalp while avoiding excessive pulling or tugging. It is recommended to wash your sew-in every 1-2 weeks, depending on your hair's needs.

  • Hydrate and Moisturize: Keep your hair and scalp hydrated by applying a lightweight leave-in conditioner and natural oils. Moisturizing your sew-in regularly helps prevent dryness and maintains the hair's luster and softness.

  • Protect at Night: Wrap your hair with a satin scarf or use a satin bonnet while sleeping to reduce friction and minimize tangles. This step protects the integrity of your sew-in and helps it retain its shape.

  • Minimize Heat and Styling: Excessive heat and styling can lead to damage and shorten the lifespan of your sew-in. Limit the use of heat styling tools and opt for heatless hairstyles whenever possible.

Handle with Care

Treat your sew-in weave with gentle care to avoid unnecessary stress or damage. Avoid excessive pulling, tugging, or rough handling of the hair extensions. Use a wide-tooth comb or your fingers to detangle the hair, starting from the ends and working your way up to the roots.

Do Sew-Ins Last Longer Than Wigs?

  • Generally, sew-in weaves tend to last longer than human hair wigs when properly installed and maintained. Here's a comparison of their durability:

  • Sew-ins can last 4-6 weeks or longer when done correctly by an experienced stylist. The extensions are braided and sewn into the natural hair, creating a very secure bond that allows the style to stay put for weeks at a time.

  • Wigs tend to last 2-4 weeks maximum before needing adjustments or a full removal/reset. Since wigs are worn overtop the natural hair and secured with removable clips, combs, or adhesive, they don't have as tight of a hold and can get loose or tangled more quickly.

  • Sew-ins only need occasional touch-ups around the hairline roots every 4 weeks or so. Wigs often need more maintenance like re-securing the adjustable straps, combing out tangles, or reapplying adhesive more frequently.

  • The tight braids and sewing method of sew-ins lead to less friction and tugging on the hair, preventing premature loosening. Wigs see more pulling that can dislodge the wig over time.

  • Sew-ins allow the natural hair to be out of sight and protected under the braided cornrows. Wigs expose the natural hair to more manipulation that can weaken the hold.

  • Lifestyle factors like workout routines, swimming, and heat can dislodge wigs quicker than a sewn-in install. Sew-ins are built to withstand more activity.

Are Sew-Ins Good for Hair Growth?

By giving your natural hair a break from the stresses of daily styling and environmental damage, sew-ins can allow your hair to grow longer and more robust. It's important to note that sew-ins should not be left in for too long, as this can lead to damage or matting of your natural hair.
