"I believe that clean-shaven men are not only attractive, but they are also perceived to be more trustworthy, caring and committed, " Neha said in a statement.
The 31-year-old, who started her Bollywood career with bold films like "Julie" and "Sheesha", recently participated in a mass shaving marathon by Gillette with actress Chitrangada Singh and 150 couples.
The campaign was also an attempt for a Guinness record of world's largest shaving lesson.
"I urge men to get rid of their shady stubble and take grooming seriously every day so that the only redness that remains on the face is from the lipstick left behind by a kiss from a woman, " she added.
