I've never seen an organization so afraid of hair.
The experiences of the younger guys being counseled for having hair cut too short just shows that it's all about control and how the cult is marketed to the masses.
When I was young, many many moons ago, us young guys loathed short hair, especially crew cuts or flat tops...which ironically enough is what most us kids were given by conservative parents and barbers with no questions asked at the kingdom hall.
Back in the lates sixties and all the way through the seventies, long hair was the fashion. Of course this freedom of expression in hairstyles was forbidden at the hall. No hair touching the collar; no hair over your ears; no sideburns lower than halfway below your ear; no mustaches covering your entire upper lip or coming down past the side edge of the lip (no fu-manchus); no beards period.
I remember one elder who went around to the younger brothers and would pull their hair. If he could pull more than an inch or so away from their head, he would tell them to get a haircut. At the time I didn't think a thing of it. I was a youngster and he was an elder...I figured he had the authority. What's disturbing now is that parents allowed this behavior by the elders, backing the authority up. Any elder did that to a kid of mine today would find himself in deep shit with me.
Nowadays, some guys like long hair, some like short, some like bald. Yet, the cult is afraid of people expressing indiviuality through something as simple as a haircut. If you want to grow it long, you'll get counseled. Cut it down to a crew cut, you'll get counseled. Shave it, you'll get counseled.
In the meantime, a conservatively dressed, short haired elder or pioneer is abusing kids and is protected by the elders so as to not bring "reproach on Jehovah" (read: protect the company)
