Alexandra Glorioso, NYU Data Analyst, Whips Up Homemade Hair Dye That Really Works

Since Rachel McAdams, Dianna Agron and Megan Fox stepped out with new red hair, we've been dying to try the trend. But as we anxiously awaited our upcoming salon appointments, we discovered a great homemade hair dye recipe from this redhead.

Alexandra Glorioso, a data analyst at New York University, is naturally blonde. (Can you believe it?) However, she colors her own hair at home with henna powder. "I have a long history of dyeing my hair and one day I looked up red dye," Glorioso told us. "I researched henna dyes for like four hours and found a lady getting her Ph.D. in henna. She had a lot of mixes and recipes and I decided to try it."

So which ingredients make up her flaming red hair dye? "I mix henna with lemon juice, Cassia Obovata (blonde plant), olive oil, eggs and vitamin E oil," says Glorioso. "I put it on my hair and you're supposed to let it dye-release, which is leaving it on overnight, but I don't because my hair is really blonde and takes color easily. Then I wrap it up with a shower cap and a towel and leave it on for about five hours."

Glorioso's final homemade hair dye tip: "The color always gets darker so I try to do it heavier on my roots because, unlike regular red dye, it doesn't fade. It's good and bad for that reason."
