Hair density refers to the amount of hair your scalp produces. This can vary by follicle placement and follicle production.
There are multiple ways to measure hair density. Scroll down for more information!
Most Accurate DIY: Ponytail Measurement
The easiest and most accurate way to measure your approximate hair density is to gather all of your hair into a tight ponytail, and to measure the circumference of your hair. This will work best on relaxed, clean, product-free hair.
Low density hair will measure at/below two inches, medium density hair between two to three inches, and high density hair will be at/above four inches.
Easiest DIY: Scalp Space
The easiest, yet somewhat more subjective, way to measure your approximate hair density is to part your hair and look at any visible scalp. This measurement can be less reliable, because you may have a higher density in some places and lower in others, and because it’s subject to your own biases.
Low density hair will have a highly visible scalp along the part, while high density hair may not show any scalp.
Most Accurate Overall: Professional
To get the most accurate analysis of your hair density, consult a specialist. For more casual analysis, asking a trusted, licensed hair stylist during your next hair cut may be the best route; these stylists see dozens of clients each week and will be able to gauge your hair density against a wide variety of others. For more serious concerns, such as sudden hair loss, visit a dermatologist who can take a magnified look at your scalp and hair follicles to determine what’s going on. Hormone changes, age, and genetics can all play a role in thinning hair or hair loss. Medical professionals can diagnose the cause and follow up with effective solutions.
Hair Density and Health
The density of your hair alone is not a determination of your health, and it is common for people to experience a range of different densities. However, it is important to talk to a doctor if you notice a change in your hair density. Sudden loss of hair, or sudden growth, could indicate an underlying medical condition. Common reasons for changes in density include shifts in lifestyle, hormone changes, age, and stress, but these changes should be slight and gradual.
