Though there has been a link between menopause and hair loss, Roberts says she doesn’t think there is a direct correlation.

For those who don’t plan on counting their hair every day, there are ways to know when hair is thinning or being lost at a higher rate.

Roberts tells Web MD that women will see a difference.

The catagen, or transition phase, typically lasts 2-3 weeks, during which the hair follicle shrinks.

During the telogen cycle, which lasts around two to four months, the hair rests.

“Growth cycles are important because when they go awry, that is one of the reasons we have hair loss.” And things that interfere with the cycle -- like medication, illness, infection, or chemicals -- have the potential to stop hair from being formed properly.

"It’s a very dynamic place and anything that can get the cycle off can cause hair loss,” Roberts says.

On the days when hair is washed, people can lose up to 250 strands, Roberts said.

But don’t avoid washing in an attempt to keep the hair, as it will fall out eventually, anyway.

The best way to think of the way hair grows is to picture a garden.

How well it grows is completely a result of what is happening “underground.” “Like a garden,a normal hair cycle should lead to a product, which is the hair,” says Wendy Roberts, MD, a dermatologist at a private practice in Rancho Mirage, Calif.

Using magnification on the scalp can show if a woman’s follicles vary in size - with some thick and others thin.
