Summary

Researchers at Al-Azhar University are studying whether type 2 diabetes is linked to changes in women's hair and scalp. The study compares 130 women aged 20 to 60, half with diabetes for at least a year and half healthy controls matched by age. Participants undergo clinical hair exams, dermoscopic scalp imaging, blood tests for HbA1c, ferritin, vitamin D, and thyroid function, plus questionnaires about hair loss severity. The goal is to describe any differences in hair density, shaft thickness, and scalp patterns between the two groups.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If a clear link emerges, doctors could one day screen diabetic women for hair and scalp changes as an early warning sign of poor blood sugar control.
What could go wrong
This is an observational study, so it can only show associations, not cause and effect. Any link found may reflect other factors such as age, ferritin, vitamin D, or thyroid status rather than diabetes itself.
