How does hair loss start?

Hair loss is a normal symptom. 50 to 60 hairs are shed each day from a normal scalp. Losing more than 60 hairs a day is called excessive hair loss and leads to generalized thinning of the hair. Hair becomes fine in texture. Loss of hair in men is often determined by heredity or by the Allopetia Androgenetic hormone. Hair loss in women is often caused by pregnancy, stress, fatigue or medical treatment.

Can Thyroid Disease Cause Hair Loss?

An overactive or underactive thyroid can cause hair loss. One may get her thyroid numbers in order after beginning a regimen of thyroid medication. However, there have been reported cases of women experiencing hair loss FROM the thyroid medication.

Hot Tips!

Coloring: If you inherited a tendency for hair loss, you likely have very healthy hair overall. Therefore, your hair can benefit from permanent or semi-permanent color to give body and volume to hair.

Volumizing Products: Many volume-building hair products contain paraffin, which is beeswax. That's not good for hair, because it builds up and can make hair break.

However, volumizing products sold in salons do help. They won't weigh hair down, and they won't damage it. Mousse, for example, can be applied at the root area for support. Then, begin blow-drying the root area, applying tension with a brush to build volume. Use a light finishing spray to hold it.
