Home / Guides / hair stress hormones

Sensitive topic

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

daygauge does not measure hair or hormones. It shows your sleep, recovery and any habits you log on a timeline, which is easier to discuss with a clinician.

The question

Start with what your own data can show.

Hair loss, stress and hormones are common searches because people want a cause.

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

Quick answer

daygauge has no hair, hormone or lab data. You can log a custom habit in Quick Log, such as a hard work week, and see it in your Timeline next to your sleep and heart readings.

Questions answered

What this guide covers.

  • Can stress affect hair shedding?
  • Can hormones cause hair changes?
  • Can an app diagnose hair loss?
  • What data helps a clinician?
  • Does daygauge measure hair or hormones?

How the app handles this.

Signal
You can export your app data from Settings to share with a clinician. Exports leave out Health readings and workouts.
Confidence
Missing readings lower confidence instead of creating false certainty.When a reading is not available, daygauge says so rather than filling the gap.
Weekly Review
Weekly Review shows what changed, what moved with it and whether the pattern repeated.Your first Weekly Review is free. Later reviews are part of Pro.
Illustrative example

What this can look like in the app.

Example: you logged a hard work week five times, and three short-sleep nights fall in the same period.

Example
Confidence

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

Next move

Try one small change, log it, then see whether the pattern repeats over the next week.

Example 1

Example: Insight shows your sleep and resting heart rate for those weeks, with no cause attached.

Example 2

Example: daygauge draws no conclusion about DHT, testosterone, thyroid, alopecia or deficiency.

Research

Further reading.

These studies describe groups of people. They help explain the topic, but they cannot tell you what will happen to you.

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

Limits

What daygauge does not do.

  • It does not diagnose, treat or prevent disease, or predict your risk of it.
  • It does not claim one habit caused a result. It shows the pattern, how confident it is and what else changed.
