When I go to a store a usually see see products like hair dye and body wax with girls on them. I look through the aisles but I notice theirs no pics for guys. I'm just wondering can a guy buy girls hair dye without it looking to awkward?
I don't see anything wrong with it. There are hair dyes for men though. Not sure about body wax, but as KERMIT said, they might be less effective on men's coarser hair.
I don't think I'd really think anything of a guy buying this stuff.. I'd probably assume he was buying it for his girlfriend or something. On the other hand, if you're embarrassed to buy it, go to a place like Walmart that has a self-checkout.
As far as external products go, there's no real reason a man couldn't use something like women's hair dye or wax, etc. It's all just marketing basically. Like these men's body washes. Chemically their usually identical for both genders. The only difference is the women's stuff smells flowery and comes in a pastel colored container (because that's what women like), and the men's stuff smells like some sort of spice and comes in a dark colored container (because that's what men like). It's all just a bunch of marketing crap. Read the ingredients on the box and buy based on that.
Hair dyes are fine. Wax products might be a problem because male hair tends to be coarser due to years of cutting (face and maybe groin region). Antiperspirants I wouldn't recommend because they don't seem to work as well.
