There are many types of hair extension applications available, depending on your hair styling needs. For many hair extension applications, natural hair is used as a base on which to apply the extensions, and hair is then cut and blended for a natural look. Parting the hair correctly before an application is one way to ensure that hair extensions remain unseen at the attachment points.
Comb clean, dry hair into the style that it is usually worn. This will give you an idea of how the hair will fall once extensions are applied.
Rake fingers gently through the hair in the rear crown area to find any cowlicks or spiral hair growth patterns that will need to be worked around.
Select a round, horseshoe-shaped area with the stem of the rat tail comb that encompasses the crown and extends to the front hairline on either side of the bang area. These side parts will naturally fall at the thinnest area of the hair.
Incorporate any cowlicks or growth patterns on the crown into this section, even if it makes the shape of the parting uneven. Twist the ends of the hair and pin atop the head with duckbill clips.
Comb hair straight on each side of the head. With the stem of the rat tail comb, draw a vertical line from the crown part to the rear of the ear. Comb the hair that falls on or in front of the ear forward. Pin each section in front of the ear with duckbill clips.
Create a horizontal part from ear to ear across the rear of the head, halfway between the bottom of the crown parting and the neck hairline. Pin up with duckbill clips.
Create a horizontal part across the rear hairline. Comb 1/2 inch of natural hair down and against the nape of the neck. This hair will be used for blending the first row of extensions. Create a 1/4-inch part just above the neckline hair. This hair will be used as the first row of extensions. Pin the rest of the section up with duckbill clips.
Parting hair for extensions is best done on straightened hair. Hair may need to be flat ironed or chemically treated before parting and application.
Chemical treatments, such as colouring or relaxers, should be done at least 10 days before hair extensions are applied.
