research Recent Findings with Computerized Methods for Scalp Hair Growth Measurements
TrichoScan effectively measures hair growth improvements in people using minoxidil.
research What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women
Caucasian women's hair appears thickest in their 20s, with perceived thinning after mid-30s due to both decreasing density and diameter.
research Analysis of quantitative changes in hair growth during treatment with chemotherapy or tamoxifen in patients with breast cancer: a cohort study
Chemotherapy causes hair loss starting soon after treatment begins and recovers about 3 months after ending, while tamoxifen does not significantly affect hair growth.
research Polycystic ovary syndrome and the differential diagnosis of hyperandrogenism
The document concludes that careful evaluation is needed to diagnose PCOS correctly due to similar symptoms in other conditions, and accurate testosterone level measurement is crucial.
