How hair loss timelines actually work
- Telogen effluvium (shedding) shows up roughly 2 to 3 months after a trigger, because hairs pushed into the resting phase take that long to fall out. If you started a hard cut, got sick or had a stressful stretch 2 to 3 months ago, that's a likelier culprit.
- Pattern hair loss progresses over months and years. It doesn't appear suddenly in two weeks.
- Daily shedding of roughly 50 to 100 hairs is normal. Seeing it in the shower drain after you start paying attention doesn't mean it's new.
Why people blame creatine
Many people start creatine at the same time as a new training block, a new diet and in their late teens or twenties, when genetic hair loss often starts. Creatine is the new thing in the routine, so it gets the blame. The 2025 trial, where men took creatine or placebo without knowing which, found no difference in hair. Full breakdown.
What to do
Photograph your hairline monthly, check your diet, and see a dermatologist if shedding lasts more than a few months or you see a pattern. Is it reversible?
Frequently asked questions
Can creatine cause hair loss in a week?
