The Science Behind Hair Density and How to Improve It

Who doesn't want a lush, thick head full of hair? Thick hair has been thought of as a sign of health and wellness in almost all cultures across the world. Seen as a symbol of longevity and a healthy physiology, dense hair is something that many people aspire for. A lot of it can be genetics that some are blessed with but fuller- looking hair can also be achieved with proper care and routine and a special focus on products and ingredients that we use.

But first, it might be relevant for us to understand the difference between hair density and hair thickness. Often used interchangeably, the two have completely different definitions. Hair Density refers to the amount of strands of hair that we have per inch of our scalp. There are many diy ways of measuring hair density but the most accurate way of doing this would be through a dermatologist who would typically use imaging technique called trichoscopy in the lab to measure this.
Hair thickness on the other hand has to do with the width of the actual strand of the hair. In this blog, we will discuss ways on enhancing hair density.

Do scalp massages help?
While there is no way to change the texture of the hair follicles, which determine hair density, there are several ways to help hair appear more dense and fuller. Using a product that repairs hair damage is helpful as it makes hair healthy and reduces hair loss. Gentle touch massage of the scalp is also very useful as it ensures better blood circulation to the follicles. According to research, scalp massage increases hair thickness by stretching the cells of hair follicles. This can stimulate the follicles to grow faster and thicker hair.

One can use a hair oil like virgin coconut oil infused with rosemary oil  on the scalp for a good massage.
