“…Hair diameters as measured by OFDA were lower in the frontal scalp in postmenopausal women; this finding was independent of age. Further analysis of this cohort as well as a larger cohort of 177 women showed that hair diameters were not normally distributed, and were typically bi‐ or trimodal (large, medium and small diameter) 36 . While the mean fibre diameter reported by OFDA is an accurate, reproducible and valuable tool for assessment of hair diameter, the diameter distribution may report a more accurate and real‐time assessment of hair diameter and diameter changes.…”

“…In a study of 44 pre‐ and postmenopausal women, without overt hair loss, modified trichogram and OFDA measurements showed that there are significant differences in hair growth characteristics between pre‐ and postmenopausal women, specifically hair growth rate, density, percentage anagen, hair diameters and hair diameter distributions 36 . These changes were more pronounced in the frontal compared with the occipital scalp.…”

Using this new measurement technology it was noted that there was a decrease in high diameter hairs in postmenopausal women.…”

Hormonal changes in menopause: do they contribute to a ‘midlife hair crisis’ in women?

Female pattern hair loss is a common problem affecting a large number of women worldwide but beset by a paucity of research. The study of androgens has hitherto dominated the field of hair biology but there is increasing scientific and clinical data to suggest that nonandrogen signals can also affect the folliculosebaceous unit, especially in women. The discovery of oestrogen receptor beta has renewed and redefined prior concepts of oestrogen activity and signalling in hair biology. It is postulated that oestrogens modulate hair growth by their influence on a number of other hormones, growth factors, transcription factors and cytokines. The menopause is a period in which significant changes in oestrogen levels are recorded, and this review discusses studies that help to clarify the link between menopause and the perception of thinning hair. In a study of pre- and postmenopausal women without alopecia, menopausal status significantly influenced hair parameters, specifically hair growth rate, percentage anagen and hair diameter distributions, most notably in the frontal scalp. Hair density decreased with age, but was not correlated with menopausal status. Analyses of hair amount using a model of hair density and hair diameters suggest that the impact of changing hair parameters is most notable in the mid-forties for women.

“…Multiple hormonal factors are known to regulate hair growth and change with age. These include circulating androgens and oestrogens, which are known to influence multiple hair growth parameters in ageing, 1,6 menopause 8 and disease 9 . There is also recognition that there are nonandrogen causes of hair thinning, including ageing, nutritional status, stress and many others 1 .…”

What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women

Increasing hair shaft diameter offsets decreasing hair density through the mid 30s. After that, a lower rate of diameter increase combined with the decrease in density begins to significantly impact the perception of hair amount so that thinning becomes increasingly more noticeable in the mid 40s to the mid to late 50s. Quantitative determination of hair amount is a useful tool to combine the contributions of hair density and diameter to women's perception of age-related hair loss.

“…It was shown to increase until the age of 40 years, and then decreases after that age. Furthermore, hair diameter distribution showed a change or downshift in the larger diameter hair fiber in pre/postmenopausal while small diameter hairs remained essentially unchanged [14]. This suggests that the larger diameter hairs may be more susceptible to hormonal changes that occur during menopause [13].…”
