What is a trichogram?

A trichogram is a microscopic examination of the hair roots.

When should you do a trichogram?

When an irregularity in the hair cycle is suspected, especially in cases of diffuse or sudden hair loss. A trichogram is usually prescribed by a doctor.




What is a trichogram used for?

A trichogram is used to accurately measure the extent of hair loss and to assess the amount of diseased hair on the patient’s scalp The doctor can confirm the diagnosis both quantitatively and qualitatively and, ultimately, decide on the most appropriate treatment.

We recommend a trichoscopy to determine the cause of hair loss.

Which criteria are examined?

Three criteria are assessed:

  • the proportion of hair in their growth phase (anagen) and resting phase (catagen), as well as the proportion of dead hair (telogen) or dystrophic hair (lesions of the hair matrix) on the frontal, temporal and occipital areas of the head
  • the proportion of anagen hair to telogen hair
  • the thickness of the hair shafts

We recommend a trichoscopy to determine the cause of hair loss.

What happens during the examination?

The doctor will extract about 60 hairs from three areas of the scalp (frontal, temporal and occipital).

Good to know
