There have been a few questions recently about hair loss, including the use of magnet therapy to restore hair growth, and especially after the menopause. The woman who first raised the problem about hair loss in a young man, whose problem went back to several serious childhood illnesses, thanks everyone for your thoughts and contributions. She is particularly attracted to the idea of health kinesiology, and wonders if there are practitioners in New York. Can anyone help. One reader suggests having the thyroid/endocrine system checked out as hyperthyroidism and hypothyroidism can affect the health of hair. Dr Barry Durrant-Peatfield, a UK doctor, lost his licence after campaigning about the under-diagnosis of thyroid problems, which is explained in his book The Great Thyroid Scandal.
