Do sew in extensions damage hair?

The short answer is: Maybe sometimes. Let’s dive into some possible pitfalls.

Not preferable for thin hairs

Sew-in hair extensions are not preferable for women with thin hair, which are more prone to hair breakage. 

not for thin hairs

The reason for this is that your natural hair will be transformed into braids, and after that, the extensions will be sewn. 

The tight sewing may result in pulling your hair, causing hair breakage or scalp damage. 

Hunt for a professional hairdresser

Unlike the other types of extensions, the sew-in extensions’ installation process is lengthy, complex, and tiring, and installing it on your own at a beginner level is quite risky. The sew-in extension takes approximately 3 to 5 hours to be done neatly. 

Thus, you may have to spend some energy hunting for a certified professional to install the sew-in extensions to give you a new look with new hair.

Difficult installation 

The sew-in hair extensions are installed using a needle, thread, and other hair extension tools. 

Sew-in hair extensions impart painful effects in case of improper handling resulting in the pulling of hair and hair damage. These problems usually occur when they are not handled or installed in a proper way, so we will surely suggest you consult a professional.

Oil buildup on scalp

Washing your hair with the sew-in extensions on is a big deal. Since the hairs are tightly braided, it increases the chances of bacteria and oil buildup on the scalp. The hair sprays used may worsen the situation and cause itching.

To avoid any possible discomfort with your hair extensions, avoid hair tangling and wash your hair properly, ensuring that the shampoo reaches your scalp to get rid of product buildup.

The takeaway:

The extension length of the shiny sew-in is up to 22 inches and comes with a double weft hair bundle, offering a thicker look to hairs. The best part I liked about this extension is that it can be installed in four different ways.

I personally experienced the UNICE colored sew-in extension and loved it because of the strong double-weft extension available in the market. The results of the double weft for maintaining the quality even after folding over were incredible!

It blends perfectly with real hair giving a much-loved wavy, curly, and brown-blonde color look. 

Takeaway: 

I just loved this sew-in extension for maintaining the quality over a long time. But I would suggest you seal the wefts before wearing the extension to prevent shedding in the future. 

How to choose the right extension? (Exactly what i look for)

choose right sew in extension

Hair extensions are the easiest way out there to add length and volume to your short hair, however, before investing in hair extension, it is important to understand what you should look for in your go-for hair extension to make the right decision and enjoy a perfect look. 

1. Know the right length of your hairs

Before stepping in to choose a hair extension, always know the right length and weight of your natural hair. This will help you to look for the correct length of extension that suits your look.  

Knowing the weight of your hair is critical in making the right decision while choosing an extension because choosing heavier hairs with thin natural hair textures can severely damage the roots.

2. Consider your lifestyle

Before selecting the right extension, it is important to take into account your lifestyle. Because hair extensions require maintenance to be more durable and to avoid oil buildup on the scalp, you should be familiar with all of the different types of hair extensions on the market.

If you are considering a sew-in extension, understand the sew-in hair extensions pros and cons for a better decision.

Also, the weft and bonding extension does not go well with the women more active in physical activities. 

3. Consider your natural hair color

The next step is to consider the color of your natural hair to avoid ending up with a mismatched extension color. 

Your extension should be perfectly blended with your natural hair to enjoy a luscious look and this cannot be possible without considering the real hair color. 

4. Quality check

Before buying the hair extension, consider how long you want to wear them and plan your budget accordingly. If you want to enjoy the long hair look for quite a long time, investing in low-quality hair extensions will be crap. 

Invest in a high-quality extension, preferably the human hair or remy extension, to style and wear it with full confidence.
