Hair loss and changes such as hair thinning must also be included in the diagnosis.

It is difficult to determine hair loss based solely on the amount of hair falling out.
You must also check the thickness and density of the hair, as well as the condition of the scalp.

Male pattern baldness, female pattern baldness, and telogen effluvium differ in their progression patterns and management approaches.
You also need to check recent weight changes, nutritional status, or medications being taken.

There are limitations to simply changing shampoos or nutritional supplements without identifying the cause.
If there are persistent changes, it is important to get an accurate diagnosis first.
