She took to Twitter to share her grief, reports contactmusic.com.
Her tweet read: "Not having hair makes me feel like a cancer patient." Bynes, who was recently charged with offences including evidence tampering, reckless endangerment and marijuana possession, was spotted in an aqua-coloured wig while on her way to a court last week.
But despite being photographed in various wigs in recent months, the 27-year-old claimed that she has never worn one. She wrote on Twitter: "When my hair grows out will everyone stop putting up fake videos of random girls in wigs posing as me?"
