Check the number of hairs on your pillow each morning. If there are more than 10, says Dr. Lai, chances are you are beginning acute hair loss. Family history counts. Diffuse thinning can also occur after surgery, childbirth and even extreme psychological trauma. But, as the hair growth cycle is three months, you will not notice any problem until about 90 days later.
Hair normally grows back without medication.
If you notice patchy hair loss, called alopecia areata, consult your doctor. But if your thinning is at the top of your head, or if your hair is receding above your forehead, there is probably nothing wrong. And there is absolutely nothing wrong with baldness, either. They both respond to treatment with the same medication, researchers in California say. To date, the anesthetic Lidocaine has been used mainly in lotions that soothe sunburned skin.
