My oldest DS wears something, I know.
Can't recall the name.
Next 2 daughters wear Secret. I also wear Secret. I start wearing it at age 9, all 3 kids started about age 9 too.
My 9 yr old came to me this summer and asked me if her pits stink. I asked her if they did, and she said, I can't tell. So, yes, I smelled her pits! And yes, she had BO!!
When I was a senior in HS my mom got a good deal on Teen Spirit by Mennan at the military PX. She must have bought 50 bottles of it. I ran out of Secret one morning, and ran back to the cupboard in the bathroom where she kept it and was bummed about the Teen Spirit. I took some, put it on, and went to school. By the end of 1st period English class, I had such bad BO, that I left school, went to Walmart and bought Secret (Powder Fresh only), went home, cleaned my pits good with a cloth, put on the Secret and got back to school before 2nd period ended! Never again have I used anything else besides Secret (even though I have ran out before and had to borrow my DH's Sure, but it's made by the same company, so it was good too).
