This is a starting point, not a diagnosis. Sudden shedding, patches or a painful scalp are worth taking to a dermatologist rather than a shelf.
What the three results mean
Curl pattern
The 1–4 system describes the shape a strand grows in, which is set by the shape of the follicle. It decides how easily oil travels down the shaft, how much a style will shrink as it dries, and how fragile the bends are. It is a description, not a hierarchy.
Porosity
How readily water crosses the cuticle. Low porosity resists water going in and takes ages to dry; high porosity takes it up instantly and loses it just as fast. Porosity is mostly acquired — bleach, heat and sun raise it — which means it can be a symptom worth treating rather than a fixed trait.
Strand thickness
The diameter of one hair, which is not the same thing as how much hair you have. Fine hair is overwhelmed by weight; coarse hair can carry heavier products and holds heat for longer, which matters when you set a styling tool.
This is a starting point, not a diagnosis. Patchy loss, a painful or scarred scalp, sudden heavy shedding, or hair changes alongside fatigue or weight change belong with a dermatologist.
