Hi,

I've read that the grow phase of hair (anagen phase) can last about 7 years and that the hair grows about 0.5 inches per month (depending on each person). World record is about 6.3 meters. How did he get so long hair then?

From Wikipedia:

Scalp: The time these phases last varies from person to person. Different hair color and follicle shape affects the timings of these phases.

• Anagen phase, 2–8 years (occasionally much longer)

I don't think the follicles on a head are in the same phase at any point in time. Also when it goes into the weakest phase, the hair is thinner, so it breaks at the slightest tension. If it's under a turban, or some such cover, it won't break off.

There are three phases of hair growth.

Extremes happen in nature, that's just, hair, life.

Wouldn't that be weird, though, if they were. Even weirder if everyone in a society ended up synchronised as well!

But it can only grow in length for about 7 years?

“2–8 years (occasionally much longer)”

Yeah, I meant about 7 years.

I think the cases of very long hair are from people whose follicles don't go through the usual catagen (shedding) and telogen (resting) phases - they are stuck in the anagen phase (growth).
