Does stress cause hair loss?
Stress has been confirmed to cause hair loss and can make you go grey but is this true?
At times stress and personal issues can take its toll on an individual but it isn’t likely to make you grey.
Stress and Hair Loss:
You possibly have heard that stress can cause hair loss, and it’s true. Excessive physical or emotional stress, like that coupled with injury, illness or surgery, can cause one of two types of hair loss:
- Common type of condition is called telogen effluvium. With this less severe type of hair loss, the hair stops growing and lies dormant, only to fall out 2 or 3 months later. Then it grows back within 6 to 9 months.
- The other type of stress-induced hair loss is known as alopecia areata, and involves a white blood cell attack on the hair follicles. With this type of hair loss, the hair also falls out within weeks (usually in patches), but can involve the entire scalp and even body hair. Hair may grow back on its own, but treatment may also be required.
Stress and Hair: The Hair Cycle
A normal head of hair contains about 120,000-150,000 strands of hair.
Usually, at any one time, about 90% of those hairs are in a growing phase, growing by about 1/2 inch each month. This phase lasts for two to three years.
At that point, a hair will go into a resting stage. This "rest" lasts for 3 to 4 months before the hair falls out and is replaced by a new one.
Usually people shed about 100 hairs a day most people don't even notice.
