Apply Hair Extensions

A: The amount of time it takes to apply hair extensions depends on the application method you choose, the amount of hair being added, and the desired finished look. Some methods can be completed in less than an hour, while others require several hours or even multiple appointments.
Other techniques require more time. For example, the track and sew method involves braiding sections of your natural hair into cornrows or tracks before sewing wefts of extension hair onto them. Depending on the amount of hair being installed and the braid pattern, this process typically takes 2 to 4 hours.
The fusion (or keratin bond) method is one of the most time-intensive application techniques. With this method, small sections of extension hair are individually attached to small sections of your natural hair using a specialized keratin adhesive and a heat tool. Because each bond is applied strand-by-strand, a full installation can take 3 to 6 hours, and in some cases, the service may be split across multiple sessions.

The faster and simpler application methods are generally the most affordable. However, they are often shorter-term solutions, may be more noticeable as artificial if not styled carefully, and require frequent re-application.
More advanced methods, such as fusion extensions, involve a greater investment of both time and money, but they also provide some of the most natural-looking, long-lasting results (often lasting 3 to 5 months). Because individual strand extensions move 360 degrees like natural hair, they offer superior flexibility when styling, including wearing your hair up in ponytails or complex hairstyles.
