Melanie Sykes has shared a candid hair loss update after previously saying that she is “two-thirds bald”. The former TV presenter, 55, posted video of herself on Instagram on Friday (26 June), showing the effects of her alopecia. Last year, the 55-year-old said she had developed the condition as a result of “PTSD from the TV industry”. She also revealed that she had been diagnosed with a heart condition and widespread inflammation throughout her body.
