TEXAS: Should a parent lose custody if he or she refuses to cut their child's hair?

A bizarre story out of Texas last month, got me to thinking about this issue of hair. And whether a parent should, or could ever lose custody of a child due to the length of the child’s hair. Now, admittedly, this seems like a dumb question on its face. But back last month, in the state of Texas, a preK student was suspended because the school administration thought his hair was too long.

BALCH SPRINGS, Texas (Dec. 17) — Taylor Pugh has been suspended from pre-kindergarten because he likes his hair a little on the floppy side….Taylor’s locks — long on the front and sides, covering his earlobes and shirt collar — violate the school district’s dress code. He has been punished with in-school suspension since late last month. More.

It wouldn’t surprise me if social services got involved in a case like this.  After all, how long can a child remain in suspension from classes before it starts to have a negative impact on his education. And by continuing to refuse to cut his hair, are the parents acting in his best interest? Are they exercising good parental judgment? Should they lose custody?
My own personal opinion is that this rule about cutting a boy’s hair is arbitrary and it is outrageous that this boy was suspended. His hair isn’t even that long. And certainly, if the concern is that the hair gets in his eyes and that this gets in the way of his learning, the parents could have been asked to put the hair back in a ponytail. But to force the parents to cut the boy’s hair or face an interruption in his education? That’s crazy. At the same time, I am a rogue liberal depending on who you ask. So I don’t always trust my judgment. Maybe I”m wrong about this. Maybe the school has a point about the cutting of a boy’s hair. In which case, should the parents lose custody if they continue to refuse to cut their baby’s hair? Is this the next step?
