Choosing the right hair extension method can make all the difference in comfort, durability, and the final look. Among the most popular and trusted options are sew-in extensions and keratin extensions. While both offer great results, they work differently and suit different hair types and lifestyles. This guide breaks down each method to help you decide which one is best for you.Haircraftluxe
Sew-in extensions involve braiding your natural hair into cornrows and then sewing wefts of hair onto the braids using a needle and thread. This technique is known for its durability and ability to hold a style for weeks.
Long-lasting hold: Can stay secure for several weeks with proper care.
Great for thick or coarse hair: The braiding foundation supports the weight well.
Low daily maintenance: Once installed, they need less styling each day.
Heat-free application: No adhesives or chemicals involved.
Tension on the scalp if braided too tightly.
Not ideal for fine or thin hair as the braids may be too bulky.
Limited access to the scalp for cleansing.
Keratin extensions use small bonds made of keratin at the tip of each strand. These bonds are melted with a heat tool and fused to sections of natural hair. This method creates natural movement and blends effortlessly.
Very natural look with individual strands.
Lightweight feel and comfortable for daily wear.
Flexible styling—can be tied up, curled, or straightened.
Suitable for most hair types, especially medium to fine hair.
Heat is used during installation.
Time-consuming application since each strand is applied individually.
Requires careful maintenance to avoid tangling near the bonds.

If you want durability and strength, sew-ins may be ideal. If you want flexibility and a naturally flowing finish, keratin extensions might be the better option.
