Good find. Interesting and useful. Superior to the Telogen Effluvium pull method. This is VERY useful for those of you who count hairs in the shower. It may help to determine where you are with your shed. I would like to see the paper though.
METHOD
The meat of it is right here. The method is:
1. Wash your hair in a sink.
2. Count hairs
3. Characterize hair length.
ANALYSIS
Criteria to distinguish Chronic Telogen Effluvium (CTE), Androgentic Alopecia (Androgenetic Alopecia), CTE+Androgenetic Alopecia
1. Androgenetic Alopecia Shed <100 hairs, > 10% of which are 3 cm or shorter = Androgenetic Alopecia.
"Of the 100 patients, 18 with 10% or more of hairs that were 3 cm or shorter and who shed fewer than 100 hairs were diagnosed as having Androgenetic Alopecia;"
2. CTE Shed >= 100 hairs, < 10% of which are 3 cm or shorter = CTE
"34 with fewer than 10% of hairs that were 3 cm or shorter and who shed at least 100 hairs were diagnosed as having CTE;"
3. Androgenetic Alopecia + CTE Shed >= 100 hairs, >10% of which are 3 cm or shorter = Androgenetic Alopecia + CTE
"34 with 10% or more of hairs that were 3 cm or shorter and who shed at least 100 hairs were diagnosed as having Androgenetic Alopecia + CTE;"
4. CTE in remission Shed < 100 hairs, < 10% that were 3 cm or shorter = CTE in remission.
"and 14 with fewer than 10% of hairs that were 3 cm or shorter and who shed fewer than 100 hairs were diagnosed as having CTE in remission."
