Kate Hudson finally convinced her six-year-old son, Ryder, to cut off his long locks.

Hudson admits it's always been a battle to give her son a haircut. "He won't let me cut it," she previously told US Weekly. In addition, she blames his rocker dad, Chris Robinson, lead singer if the Black Crowes. "I think it's a daddy thing," she said. "His daddy's got long hair so he loves his long hair."

For a while now, Hudson's son was not the only little boy in Hollywood with long hair. Remember Cindy Crawford's son, Presley, with the long blonde locks that she referred to as "surfer-dude cool"? Elle Macpherson and Celine Dion both had long-haired kids that you would swear were girls -- only they weren't.

While we're all for individuality and expressing yourself with your hair, at what point does this become damaging for a little boy if he is being mistaken for a girl? Are their parents setting them up for an identity crisis or are they just having fun with their child's looks?

According to L.A.-based psychotherapist, Heather Turgeon, it's okay for parents to let their boys have long hair. "Kids get enough pressure to conform to gender expectations from their peers and society, it's not necessary for parents to add to this pressure by trying to force one look or another," Turgeon says.

Acknowledging, though, that boys have it harder than girls when it comes to conforming, Turgeon says it's more acceptable for a girl to be a tomboy than for a boy to be feminine, and the point that this could become damaging is when they start to feel outcast by their peers.

"In the early years," Turgeon says, "parents can take more control, but as kids enter school, they should be encouraged to express themselves and have more say in their appearance."

Turgeon adds that being mistaken for a girl will have no impact on a child's "gender identity" because that is something that is a biological, hardwired part of our personality. "As kids move into school age, if they act like the opposite sex they are more likely to be teased or rejected by peers, because young children are even more black and white about gender than adults," she says.

While this is not an issue for preschool kids because they are not judgmental yet, being ridiculed beyond those years can set kids up for lower self-esteem according to Turgeon.

So what is a parent to do in the often judgmental society that we live in? Turgeon reminds us not to worry about altering a child's sense of gender identity or sexuality. "If your girl refuses dresses or your boy wants to paint his nails, keep an open mind," she says. "Talk to your kids and help them process the raised eyebrows or peer rejection they might be facing, and then offer alternatives, but don't force anything."

What do you think of boys having long hair? How about styling products just for kids? Right or wrong?
