Amanda Bynes' latest bizarre behavior now includes slamming both the media and a lavish hair salon.

Bynes vented her frustration on Twitter Tuesday when she posted a rant against celebrity hair stylist John Barrett. She uploaded a photo of herself with a long blonde ponytail and captioned the picture: "I love my hair this way! This is before a hair stylist @ John Barrett FRIED my hair with bleach then lied2 Intouch." 

A rep for the John Barrett Salon in New York City's Bergdorf Goodman issued a statement in response to Bynes' Twitter rant.

"We do not comment on clients' presence in the Salon and as such, I cannot comment on the validity or legitimacy of Ms. Bynes' claim," Zachary Anderson, the salon's public relations and social media coordinator, told E! News.

On Monday Bynes was seen reading an InTouch article that Barrett is alleged to have been featured in, as he discussed the What I Like About You star.

A hairstylist a salon in Queens said she worked with Bynes recently and when the actress came in for a visit, she was "definitely on something."

"I don't know what she was on exactly, but she was definitely on something," the unidentified hairstylist told Radar Online.

The hairstylist revealed that Bynes wore her sunglasses during her four-hour visit, and she was so strange that the salon's staff called police and asked them to wait outside the salon until she left.

"It's really sad. I feel bad for her," said the stylist. "Her mother needs to come and find her, and save her."

Bynes' Twitter rant and weird salon visit adds to her growing list of bizarre behavior since she moved to New York from Los Angeles last fall.

On Monday she was also photographed smoking a suspicious-looking cigarette, the same day New York Post published a report saying she was kicked out of a gymnastics class at New York City's Chelsea Piers.

Last week, Bynes tweeted that she is suffering from an eating disorder and last month she sent a raunchy text message to Canadian rapper Drake.
