How to Care for Your Sew-in Hair Extensions

If you’re looking for more length or volume to your locks, sew in extensions are a great adhesive-free option that can instantly transform your look. Like everything else it starts with a consultation with your Tease Hair Boutique stylist, who can match your hair color and texture to come up with a custom plan.

Before you know it you’ll be walking out of the salon with the hair you’ve always dreamed of, but an important question we may have forgotten to ask our stylist in all the excitement is how to care for your extensions. In this guide, we’ll give you an overview of the do’s and don’t of hair extension care for sew-in wefts.

What are sew-in extensions?

Also commonly called “beaded wefts”, sew-in extensions start with sectioning of your hair. Your stylist will determine how many rows you need depending on the length of your hair and overall density. Your stylist will then add small beads to section of your hair, clamping them shut in a ring shape around your head. The number of beads used also depends on the style of extensions and the application method your stylist is using.

Once the beads have been applied, your stylist then uses a special needle and thread to sew the weft of hair along the line of beads, tying them off at the ends to secure. Once they’ve been applied, it’s as simple as style-and-go!

Depending on the brand and method, sew-in extensions can last anywhere from 6 - 12 weeks before you’ll need them re-applied. Factors like the quality of the hair extensions will also determine how long you can use the same set before you’ll need to purchase new ones, generally ranging from 2 - 4 re-applications. However, with the right products and care methods you may be able to extend the life of your extensions a little longer.

Extension Care Tips

Brush your hair extensions regularly

And when we say regularly, we mean often. Always brush your hair before you get in the shower to avoid tangles and matting. Use a soft-bristled brush or a wide-tooth comb to gently detangle your hair extensions daily.

With short bristles that smooth and detangle locks without interfering or getting caught on the beads, this brush is the perfect extension brush. When brushing, hold your hair like it’s in a ponytail and start brushing from the ends, gradually work your way up to the roots.

Wash your hair extensions carefully

Wash your hair extensions with a sulfate-free shampoo and conditioner. Gently massage the shampoo into your hair extensions, avoiding any twisting or rubbing. Rinse thoroughly with lukewarm water and apply conditioner to the ends. Rinse and gently squeeze out any excess water before using a lightweight detangler and brushing.

Avoid using too much heat

Heat styling tools such as straighteners, curling irons and hair dryers can damage your hair extensions.When styling your hair extensions, be gentle and avoid pulling or tugging on them. If you must use heat, use a heat protectant spray and keep the temperature low.

Use a silk pillowcase and secure hair before sleep

As we all know, morning hair isn’t always the prettiest - especially when you leave your extensions down or go to bed with wet hair. To avoid matting and knots, make sure to gently brush hair before bed, securing it in a braid, a bun or ponytail using a scrunchie or a silk turban. For added softness and to avoid friction while you sleep, use a silk pillowcase.

Don’t over wash

Avoid over-washing your hair extensions to prevent dryness, breakage, or discoloration and fading. While most companies recommend washing extensions only once or twice a week, keep your scalp health top of mind and understand what is right for your hair. To elongate your look between washes, use a light dry shampoo to remove grease and a leave-in conditioner to add moisture back into ends.

Bottom Line

While the idea of caring for extensions may seem daunting, you’ll be surprised how quickly these small adjustments become a part of your routine - and how easy they feel. You’ll probably also save time on styling with extensions, and the better care you take of them the longer they’ll last!
