What is the difference between anagen effluvium and telogen effluvium?

πŸ’‘ Quick answer

A cancer-treatment drain is not a 16:8 story. Oncology owns that care. Photograph only if the oncology team agrees.

Mixing the two clocks confuses forums. HairBase will not invent a millilitre for either. Related: telogen-effluvium-clock β€” different URL.

Do not start oral finasteride during oncology without the team. Do not double minoxidil on a denuded scalp unless they said so.

Fever and neutropenia are oncology emergencies, not a HairBase essay. This is not medical advice.

Same as TE clock?

Related shed family, different URL. This file is the distinction.

More foam during chemo?

Only if the oncology team agrees. Do not invent a protocol.
