What is Hair Density? How to Measure and Increase Hair Density?

Updated at Feb 28, 2025

You can classify your hair in a variety of ways, including length, color, texture, coarseness, and density. The number of strands of hair that grow per square inch of your scalp is referred to as your hair density. Hair density is one factor that influences how you should style your hair.

It is not necessary to use a microscope to count individual strands. Simply knowing whether your hair density is on the thin or thick side can help you determine what type of hair products to use.

What is Hair Density?

Hair density is the number of hair strands per square centimeter of the scalp. It is a key factor in determining the appearance of fullness and thickness in hair. People with high hair density typically have thicker-looking hair, while those with lower density may experience visible scalp exposure. Hair density varies from person to person and can be influenced by genetics, age, health, and hair care habits.

What are the Types of Hair Density?

Hair density is generally classified into three categories:

  • Low Density: Fewer hair follicles per square centimeter, making the scalp more visible.
  • Medium Density: A balanced number of hair follicles that provide a natural volume.
  • High Density: A large number of hair follicles, resulting in thick and voluminous hair. Understanding your hair density can help in choosing the right hair care routine, styling techniques, and treatments.

How to Measure Hair Density?

There are several ways to measure hair density:

  1. Visual Inspection: Observing how much of the scalp is visible when parting the hair.
  2. Strand Count Test: Measuring a small section of the scalp (e.g., 1 square centimeter) and counting the number of strands.
  3. Professional Analysis: Dermatologists and hair specialists use digital scalp analysis tools to determine exact hair density.

How to Increase Hair Density?

If you want to improve hair density, consider the following methods:

  • Proper Nutrition: Eating a protein-rich diet with vitamins like Biotin, Vitamin D, and Iron can promote hair growth.
  • Scalp Care: Regular scalp massages improve blood circulation and encourage hair follicle activation.
  • Medical Treatments: PRP (Platelet-Rich Plasma) therapy, minoxidil, and finasteride are common treatments to enhance hair density.
  • Hair Transplant: A professional hair transplant can restore lost density by redistributing hair follicles.

What Can Reduce Hair Density?

Several factors can contribute to hair thinning and reduced density:

  • Genetic predisposition
  • Hormonal imbalances
  • Nutritional deficiencies
  • Stress and lifestyle habits
  • Overuse of harsh hair products or heat styling

Can a Hair Transplant Increase Hair Density?

Yes, a hair transplant is one of the most effective ways to increase hair density, especially in individuals experiencing hair thinning or baldness. The FUE (Follicular Unit Extraction) method allows for the precise transplantation of healthy hair follicles to areas with reduced density, resulting in natural-looking and long-lasting results.

Determining Hair Density

Counting the individual strands in a 1-inch by 1-inch section of your scalp is the most accurate — but least practical — way to measure your hair density. In lab settings, researchers commonly use an imaging technique known as trichoscopy to accomplish this. A phototrichogram, an imaging technique that allows researchers to measure hair density and the growth phase of each individual hair, is the gold standard method of measuring hair density. Hair restoration techniques such as FUE also increase your hair density and create a better look.

What Does Your Hair Density Mean In Terms Of Hair Care?

Knowing your hair density can help you determine which hairstyles and hair products will work best for you. Remember that your hair's coarseness, length, and texture, as well as your personal style, all play a role.

Low-density: If you have thin hair, you should avoid heavy products that weigh it down, such as heavy oils and conditioners. Look for volumizing shampoos, dry shampoos, and mousse to add volume to your hair. Hairstyles that add volume to your hair can help your hair appear thicker. Many stylists advice sticking to blunt-lined haircuts with few layers.

Medium-density: You don't need to do much to change the volume of your hair if your hair density is in the middle. While experimenting with different hairstyles and products, you can concentrate on products that help keep your hair healthy.

High-density: If you have thicker hair, you may need to use heavier styling products like gels and butters to get your hair to stick and stay in place. Serums and oils may aid in the reduction of frizz. Hairstyles that reduce bulk may be best for you. Layering can help make your hair appear thinner, and many stylists advise against using blunt cuts.

Is it Possible to Increase Hair Density?

Hair density, like many other aspects of hair, such as color and texture, is determined by genetics. Hair grows from a part of your skin known as a hair follicle. The number of hair follicles you have cannot be changed.

Hair transplant surgeries can help cover up patchy areas of hair growth, but there is currently no way to change if you were born with low hair density. Eating a healthy diet can help you maximize your hair density potential.
