Sensitive topic

Hair changes need a timeline, not a premature cause label.

daygauge can organise sleep, stress, illness, nutrition notes and lab dates so a pattern is easier to discuss with a clinician.

Why people search this

Start with the signal your own data can support.

Hair loss, stress and hormones are high-intent searches because users want a cause.

A lifestyle app should not guess DHT, testosterone, thyroid, ferritin, alopecia or deficiency. It can make the timeline clearer.

Quick answer

daygauge can collect user-entered hair notes, photos if added later, stress-week markers, sleep disruption, illness notes, supplement changes and lab dates.

How daygauge would use this

From research context to product evidence.

Signal
daygauge can collect user-entered hair notes, photos if added later, stress-week markers, sleep disruption, illness notes, supplement changes and lab dates.The output should be an exportable timeline, not a cause label.
Confidence
Missing or sensitive data lowers confidence instead of creating false certainty.If the signal is not measured, explicitly imported or user-approved, daygauge should say so in the evidence.
Weekly review
Pro keeps the weekly baseline review: what changed, what moved with it, and whether the pattern repeated.This is where daygauge should beat a generic wearable dashboard: better explanation, clearer baselines and safer boundaries.
Example evidence

What a user should expect to see in the app.

Hair note logged after 5 high-load weeks and 3 short-sleep nights.

Data used

daygauge can collect user-entered hair notes, photos if added later, stress-week markers, sleep disruption, illness notes, supplement changes and lab dates.

Confidence

Confidence rises when the same pattern repeats against your own baseline and drops when key signals are missing.

Next move

daygauge would suggest one small experiment, then watch whether the evidence repeats over the next week.

Boundary

Research context only. daygauge does not diagnose, treat, prevent or predict disease risk. Personal medical concerns belong with a qualified clinician.

Evidence 1

Hair note logged after 5 high-load weeks and 3 short-sleep nights.

Evidence 2

Manual lab timeline includes ferritin, TSH or vitamin D only if the user imports them.

Evidence 3

Boundary: no DHT, testosterone, thyroid, alopecia or deficiency inference.

Safety line

Research context

Sources daygauge can cite without overclaiming.

These sources are used as context for product wording and evidence labels. They should not be turned into personal disease-risk estimates.

Product boundaries

What daygauge should not claim.

  • No diagnosis, treatment, prevention or personal disease-risk prediction.
  • No hidden inference from sensitive data such as fertility, hormones, glucose, labs, cycle context or exposure tests.
  • No guilt language, food moralising, overtraining incentives or leaderboard use for sensitive topics.
  • No claim that a single habit caused a result. daygauge can show patterns, confidence and possible confounders.
