Does intermittent fasting cause hair shedding?

💡 Quick answer

Photograph the part. Do not treat a dining-window app as a dermatology protocol.

Telogen effluvium after crash diets is an old clinical story the AAD already describes. Time-restricted eating that still meets energy and protein needs is not automatically that crash. Very-low-calorie stretches, rapid weight loss, and nutrient gaps are the more honest suspects. This page will not invent a PMID that “proves 16:8 causes Norwood 3.” Androgenetic maps remain until a clinician says otherwise. This is not medical advice.

Do not stop labelled minoxidil because a podcast blamed breakfast. Do not start oral finasteride from a fasting screenshot. Related files cover seasonal shed and protein; those are different URLs. Eating disorders need medical care, not a HairBase millilitre.

Fainting, chest pain, or a child on a crash diet is a clinic, not this essay. Painful clumps skip the fasting debate. This is not medical advice.

FAQ

Does 16:8 always shed?

No. A well-fed window is not a crash by itself. A patterned part is still an exam.

Should I eat more to save hair?

Enough energy and protein belong in a clinician’s nutrition list, not a dump-minoxidil plan.

Can I raise foam while fasting?

No. Follow the carton. Fasting is not a third coat.

Same as low-protein-diet-and-shedding?

Cousin file. This URL is the clock and the window. That URL is protein grams.
