What is a scalp analysis?

What a scalp analysis actually measures

Almost every protocol — clinical or digital — looks at the same small set of variables, because these are the ones that change hair outcomes.

• Oiliness (sebum output): heavy sebum traps debris around the follicle opening and feeds Malassezia yeast.
• Dryness and barrier condition: tight, dull skin that flakes in fine powder rather than greasy plaques.
• Flaking / dandruff: how much scale is present and whether it is dry or oily.
• Sensitivity and redness: irritation, reactivity, visible inflammation.
• Follicle condition: whether openings are clear, how many hairs share one opening, and whether shafts vary in thickness.
• Hair-loss risk signals: miniaturized (thin, short, wispy) hairs mixed with normal ones, especially along the hairline and crown.

Why the scalp, not the hair

Hair strands are dead keratin. Once a strand leaves the follicle, nothing you do changes how it was built — you can only protect it. Everything that determines thickness, growth rate and how long a hair stays in place happens below the surface, in skin that is subject to the same oil, inflammation and barrier problems as the rest of your body.

That is why two people with identical symptoms — 'my hair is limp and falls out' — often need opposite routines. One has sebum build-up suffocating the roots; the other has a stripped, irritated barrier from over-washing. A scalp analysis is what separates those two cases.

How to read your scores

Scores are only useful as a direction, not a verdict. Treat the first scan as a baseline, then compare it to the next one taken under the same lighting and angle.

A moving trend — oiliness dropping from 74 to 55 over six weeks — tells you the routine is working. A single number tells you very little.

• Follicle health: higher is better; above 70 is healthy.
• Oiliness, dryness, flaking, sensitivity, hair-loss risk: lower is better; under 30 is comfortable, over 60 needs attention.
• Overall score: a weighted summary designed to be tracked month over month.

When to see a doctor instead

A scan is guidance, not a diagnosis. Book a dermatologist if you have persistent itching or burning, patchy or circular hair loss, sores or bleeding, sudden heavy shedding, or scaling that does not respond to a medicated shampoo within four to six weeks.
