What is Curl Density?
Curl density refers to how many individual hair strands grow per square inch of your scalp. Curltine measures density as part of your hair scan and uses it to tailor your wash-day routine and product volume recommendations.
The three density categories
Low density hair has fewer strands per square inch. The scalp is often visible through the hair. Low density hair benefits from lightweight products that do not weigh strands down or create the appearance of flatness.
Medium density hair is the most common category. The scalp is not easily visible and the hair has a balanced appearance. Medium density hair is versatile and works well with most curl care approaches.
High density hair has many strands per square inch. It can appear thick and full but may take longer to dry and requires thorough product distribution. High density hair benefits from techniques like raking or shingling to ensure even product coverage.
How to estimate your hair density
You can estimate density by gathering your hair into a ponytail and measuring the circumference. A circumference under 2 inches typically indicates low density. Two to four inches is medium density. Over four inches is high density.
Curltine estimates density from your hair scan photo by analyzing the visual thickness of the hair as a whole, not individual strands.
How Curltine uses density in your routine
Curltine uses your density level to recommend appropriate product amounts and application techniques. High density users may see guidance on sectioning hair for even coverage. Low density users may see guidance on avoiding heavy products that flatten roots.
Density also affects Curltine's routine step recommendations. For example, diffusing time estimates and conditioning rinse methods differ based on density level.
Frequently asked questions
Does Curltine measure my hair density?
Yes. Curltine estimates hair density as part of every hair scan. The result is shown in your Curl Score alongside curl type, porosity, and frizz level.
Does density affect which products Curltine recommends?
Yes. Curltine considers density when evaluating products. Lightweight formulas are better suited to low density hair, while richer products work better for high density hair without the same risk of weighing it down.
Is curl density the same as hair thickness?
No. Density refers to the number of strands per square inch. Hair thickness refers to the diameter of each individual strand, which is sometimes called strand width or texture. Curltine measures both as separate characteristics.
How Curltine helps with what is curl density?
Curltine analyzes your hair from a photo scan and builds a personalized wash-day routine and product recommendations matched to your curl type and porosity.
