Is the ponytail density test accurate? The one where you measure the circumference of the ponytail (<2 in. Is low, 2-3 in. Is medium, and 4 in or more is thick).
In theory it makes sense but it obviously a 4 inch ponytail of fine strands is going to have a greater number strands than a 4 inch ponytail of coarse hair.
I just did the density test and I'm thinking mine is pretty high.. I have fine strands but the ponytail is 5.5 inches.
2A/B. Mix of fine, medium, and coarse (mostly medium). Dense. Mix of normal and high porosity.
