Step 1: Selecting the Right Sew-In Extensions
The first step involves choosing the right sew-in extensions, which starts with understanding how sew-in hair extensions work. Available as synthetic or human hair extensions, sew-ins work around the concept of a longer install that allows for flexibility, too.
Decide the kind of weave that you want, including whether the hair length should be short or long, what the color should be, texture and more. Ideally, quality hair extensions that last long should be virgin remy human hair extensions.
Also, analyse your hair to understand which kind and volume of sew-in hair extensions would be a fit for you. If your hair is too thin, then ideally, go for lighter extensions to prevent damage and ensure a better look.
Step 2: Wash and Condition
Washing and preparing not only your natural hair but also your sew-in extensions is essential. Get your tools ready and wash your hair as advised by the manufacturer. A general rule of thumb is to use lukewarm water, a sulfate-free shampoo and a hydrating conditioner.
A cleaner scalp allows for a better grip and, therefore, a longer-lasting install. After washing, ensure that your hair and scalp are completely dry to prevent the growth of bacteria and to reduce the effects of product buildup.
Step 3: Prepare the Scalp and Hair Extensions
After preparing your scalp, it is time to prepare your human hair extensions. Grab a curved needle and a thread that resembles your hair color.
Part the hair into even sections and clip them off. Start by braiding the hair into cornrows horizontally from ear to ear. Make sure the hair is evenly distributed and the braids are not too small, as this will reduce the grip ability.
Step 4: Sew-In the Extensions
Now it's time to take action and sew the wefts. Using one set of sew-in hair extensions and a needle and thread to latch it onto the cornrows tightly. Sew through the cornrows while ensuring the sew-in lays flat.
Trim the excess weft and tie it off to secure it using a stitch and a closing braid. Make a tight braid at the end to keep it from unraveling, and check the entire install for any loose ends.
Step 5: Style and Care
After installing your sew-in hair extensions, take these steps to style and care for them best.
- Alter the hair by trimming it to your desired length and style.
- Use sulfate-free products that are safe for hair extensions, and wash the hair every 10 days. Avoid washing too often, as this can strip the hair of its natural oils. However, wash well to reduce product buildup.
- Use heat styling sparingly, and use a heat protectant when applying heat.
- Avoid using tight hairstyles as they can pull on the sew-in and cause it to unravel.
- Every 6-8 weeks, check in with a professional to ensure the health of your hair and the durability of your install.
- Manage damage by ensuring a clean scalp and accounting for hair growth to keep the hair looking neat and flawless.
