Princess Diana is known for many things, including her influential fashion choices and unforgettable hairstyles. In a new interview, one of Princess Diana's hairdressers opened up about Princess Diana's personality, including what made her laugh.

Hairdresser Richard Dalton has collaborated with Renée Plant, curator of the Princess Diana Museum, on a new book titled It's All About the Hair-My Decade with Diana. “Having seen Princess Diana every day for more than 10 years, it was fun to reminisce. It was fun to look back,” Dalton told People. He also noted “how funny Diana was” and described “how wonderful and genuine she was.”

Dalton also noted Diana's “wonderful, wicked sense of humor” and that “her jokes were hysterical and ...... Sometimes they were very naughty,” he explained in his book (via People).

“She always had plastic vomit and plastic dog poop in her bag, which she would leave on people's seats on long flights,” Dalton recalled.

“She was hysterically funny and loved to crack jokes on all of us.” [...] [...] [...] [...] [...] [...] [...] [...] [...] [...] [...] [...]
