This is the 40th installment of the classic actress beauty tips that I have read about and tested.
I have tried several beauty tips over the years – some of the craziest seem to involve hair: Rinsing hair with champagne and beer, or bleaching it blonde.
My most recent hair experiment comes from Greta Garbo and may also be the tamest. I learned this tip from film writer and professor Thomas Doherty on Twitter.

Greta Garbo photographed by Clarence Sinclair Bull in 1932
Greta Garbo was one of Hollywood’s top stars from 1925 to 1941. The Swedish star, however, was known for avoiding reporters.
While in New York City in late 1931, Garbo was traveling under the name Gussie Berger and refused interviews with reporters. So enterprising reporter Dorothy Ducas of the International News Service disguised herself as a hairdresser’s assistant to get a story, according to the Editor’s Note of Ducas’s Jan. 4, 1932, article “Glamorous Garbo Gives Good Interview Out to Girl Reporter in Gotham.”
