The generic name is minoxidil and it is sold as Ro-gaine and Regaine, depending on the market. But even minoxidil will not work for some people. Some users have complained of scalp irritation, and some with low blood pressure report a further drop, plus dizziness. 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.
