Ventilation Style: Understanding Parts, Breaks, and Hair Direction

You will hear the word “ventilation” quite a bit in the world of hair replacement. Ventilation can refer to the method in which hair is attached to the base of a hair system, such as knotted or injected. But for our purposes here, ventilation describes the direction in which hair is attached — or ventilated — into the base.

You can ask to have your hair system ventilated in the direction you’d like the hair to fall — called a “break” — or you can request a more distinct separation, a hard line where there is no hair added — called a “part.” There are additional ventilation styles as well, such as brush forward, brush back or overall curl. Unless you have specific requests, we choose the ventilation style that best matches your requested hairstyle.

You will see reference to “crowns” — or hair whorls — throughout this page. The crown is a circular patch of hair growing in the opposite direction of the remaining hair.

Please note: The following illustrations only depict the direction the hair is ventilated into the base, based on the requirements of the requested hairstyle. Once the hair is properly cut, blended, and styled, the hairstyle will look more natural and the desired style will be achieved.

Brush back

In this style, hair falls back away from the face, while still completely covering the base. There is no part or break. Because the hair is brushed straight back, there is no crown.

Brush forward

The opposite of brush back: the hair at the top of the system falls forward, and the sides and back fall straight down. There is no part or break, but there is a center crown with this style, located at the top of the back of the head, where it begins to curve down.

Brush forward from left to right

The hair at the top of the system falls forward and towards the right; the sides and back fall straight down. There is no part or break, but there is a crown.

Brush forward from right to left

The hair at the top of the system falls forward and towards the left; the sides and back fall straight down. There is no part or break, but there is a crown.

Part right/left/center

As mentioned earlier, hairstyles with a true part have a distinct line where there is no hair ventilated. With a right part, hair falls to the right of this line; with a left part, hair falls to the left; and for a center part, hair falls evenly on both sides.

Break right/left/center

A break in the hair is similar to a part, but much softer and less distinct. The break is ventilated with hair, and there isn’t a clear line of demarcation. The hair simply falls in opposite directions on either side of the break line. We can choose the break location, or you can designate it on a template.

Overall curl

Essentially, overall curl is freestyle ventilation done with curly hair and no crown. Because hair is curled prior to adding it to the base, it can’t be ventilated in a specific direction. Overall curl can only be ordered with tight curls for short hairstyles.
