Hair density is a measurement of how many strands grow per square inch on your scalp.
While we use length, texture and thickness predominantly to categorise hair type, the matter of density is less widely discussed and varies from person to person. It’s not a synonym for thickness, it’s a case of the quantity of strands rather than if it’s thick or fine.
If your scalp is easily visible under bright light, this is a signaller of low density. Density falls into three categories; low, medium and high and while these are not a signaller of health and are generally a matter of genetics, it is something to consider when selecting the products that deserve their place on your bathroom shelf.
This is particularly true for folks with low density. For those with thinner hair, it's best to steer clear of heavy oils and rich conditioners that will weigh down and flatten strands. Instead, volumising and texturizing products deserve a place in our haircare arsenal, imparting volume and resulting in a thicker-looking appearance.
Beyond styling products, some formulas will encourage a denser hair look. The key is to douse your scalp with the right nutrients to stimulate microcirculation and thus, growth. Nutrition and diet play a key part too.
Anabel Kingsley, Brand President & Consultant Trichologist at Philip Kingsley breaks it down further by highlighting six points to enhance the thickness of your mane:
