You can see a thorough tutorial on how to apply and blend in your invisible wire extensions https://www.youtube.com/watch?v=LXH4My7mcZs&ab_channel=USAHAIR
Here are additional things to keep in mind:
Styling Together: Style your natural hair and extensions together to ensure they blend well. Use curling irons, straighteners, or other styling tools to create a unified look.
Concealing the Wire: The wire of invisible extensions can sometimes be visible. To hide it, part your hair strategically or cover the wire with a thin layer of your natural hair.
Use Hair Products: Apply hair products like leave-in conditioners, serums, or styling creams to both your natural hair and the extensions. This will help smooth and unify the two textures, reducing any noticeable differences.
