Atar Gold is a brand new natural fragrance serum made with 24 carat gold. Teri Donnelly and co-founder Tony Beckerman were launching the new product at CosmoProf 2012.

"It's a game changer," says Teri. "It's designed for both men and women. The serum is heat activated and reacts to your body chemistry. It will go 'fresh and powdery', 'spicey' or 'woody'. Atar means natural fragrance and on top of everything else it actually has healing properties."

After a swipe on my arm, I was able to see (rather smell) how Atar Gold DOES change scent. Although the first "notes" were "woody", within ten minutes I was all "fresh and powdery".

"It's really a sophisticated fragrance," she says. "It's great for the salon professional and the salon client."
