Short Answer
Complete Explanation
In cosmetology and hair care, volume refers to the amount of space that a hairstyle occupies. Unlike density, which describes the number of hairs per square inch of the scalp, volume describes the “lift” or the distance the hair stands away from the scalp, as well as the overall expansiveness of the hair’s silhouette.
- Lift: This is the ability of the hair to stand up away from the root. High lift results in more volume, while hair that lies flat against the scalp is described as having low volume.
- Body: Often used interchangeably with volume, body refers to the structural integrity and bounce of the hair, preventing it from appearing limp.
- Fullness: While related to density, fullness in terms of volume refers to the visual impression of a thick, airy mass of hair created through styling or natural texture.
History / Background
The pursuit of hair volume has been a central element of global grooming and fashion for centuries. In various historical eras, volume was often used as a symbol of status, health, or femininity. For example, the elaborate wigs of the 18th-century French court utilized padding and frames to achieve extreme volume. In the mid-20th century, the 1950s and 60s saw the rise of the “beehive” and “bouffant” styles, which relied on backcombing (teasing) and heavy lacquers to sustain artificial volume. These trends shifted the focus from the natural growth of the hair to the architectural manipulation of the hair’s shape.
Importance and Impact
Volume significantly impacts the visual balance of a person’s facial features and overall silhouette. In professional cosmetology, manipulating volume is used to correct perceived asymmetries or to complement specific face shapes. For instance, adding volume at the crown can elongate a round face, while volume at the sides can soften a long, narrow face. Furthermore, the perception of volume is often linked to the perceived health of the hair; limp, flat hair is frequently associated with damage or lack of vitality, whereas voluminous hair is often viewed as a sign of youth and vigor.
Why It Matters
Understanding volume is practical for consumers when selecting hair care products and professional services. Many products marketed as “volumizing” work by adding temporary thickness to the hair shaft or by lifting the root using polymers. Distinguishing between volume and density allows individuals to address their specific hair concerns—such as using a volumizing mousse for flat hair versus a thickening serum for thinning hair. This distinction prevents the misuse of products that may not provide the desired aesthetic result.
Common Misconceptions
Volume is the same as hair density.
Density refers to the number of follicles on the scalp; volume refers to the space the hair occupies. A person can have high density (many hairs) but low volume (hair lies flat).
Only people with thin hair need volumizing products.
People with thick or coarse hair may also seek volume to prevent their hair from looking “heavy” or flat, often using techniques to create lift and movement.
FAQ
Can volume be permanent?
No, volume is generally a temporary state achieved through styling, products, or haircuts. Natural volume is determined by genetics and hair health, but specific "lift" is temporary.
What causes a loss of volume?
Aging, hormonal changes, product buildup (weighing hair down), and damage to the hair cuticle can lead to a loss of volume.
Does cutting hair shorter increase volume?
Yes, shorter hair is lighter and less prone to being pulled down by gravity, which often makes it appear to have more volume than long hair.
