Many possible causes
According to the American Academy of Dermatology (AAD), hair loss has many causes. They include inherited hair loss, age, childbirth, illness, surgery, or a stressful time, thyroid disease, too little biotin, iron, protein, or zinc, some medications, and hairstyles that pull tightly.
Signs to watch for
The AAD says that in women, the first sign of inherited hair loss is usually overall thinning or a widening part. The AAD also says you may notice a lot more hair in your brush or on your pillow a few months after giving birth, an illness, or an operation, or after a stressful time.
Why see a dermatologist
The AAD says the key to effective treatment is finding out what is causing the hair loss. It also says seeing a dermatologist is especially important if you are concerned about thinning hair or hair loss, and that the sooner the problem is addressed, the better. A doctor or dermatologist can look for the cause.
What shampoo can and cannot do
Volumizing shampoos are cosmetics. They clean the hair and can change how it looks and feels. They do not treat hair loss or scalp disease. A volumizing shampoo can make hair look fuller for a while. The effect washes out.
Medication
If you think a medication is causing hair loss, the AAD advises asking the doctor who prescribed it. Do not stop a medication without talking to your doctor.
