Of course it's possible to treat baldness, but one needs to question whether a particular treatment is a good treatment, or whether it's a mediocre and less effective one. Also bear in mind that a treatment which is effective in one individual may not necessarily be effective in another as there are various causes for baldness and of course variations in the physiology from one individual to another. There are many excellent cures available in the conventional medical arena; these often utalize prescription drugs. However many people have concerns about the use of man made drugs since natural hair restoration methods of one form or another is these days becoming increasing popular.
Hair loss may have a variety of causes. Hormonal imbalance is one cause, an over or underactive thyroid can cause loss of hair as can an incorrect balance of androgens or estrogens (the male and female sex hormones), these can usually be treated by your doctor with the appropriate drug therapy, for instance an underactive thyroid has implications for health of a greater importance than losing hair and would be treated by a drug such as thyroxin. This would restore the correct thyroid level, and cure the various symptoms associated with thyroid deficiency. Bearing the above in mind, I would advise considering any concerns you may have about your hair loss with your doctor for your own peace of mind.
Certain illnesses may cause some degree of baldness, as can an incorrect diet resulting in a deficiency of certain key nutrients. Certain types of medication may cause baldness, however I feel obligated to warn you that if you are taking medication which may be causing baldness as a side effect, you should not stop your medication without consulting your doctor, if you stop without medical advice you could seriously endanger your health. There is also in some individuals a genetic tendency to baldness.
There are many methods by which one can treat baldness. There are various medical specialists who may be able to offer therapies, which may help to alleviate hair loss. There are several different types of drugs which can help, these drugs being available either by prescription or over the counter depending on their type. Many people however would prefer to consider natural hair loss restoration techniques before using pharmaceutical drugs. There are two main reasons for this. Firstly concern about possible side effects and secondly expense. There are many natural treatments available. As you can imagine, some of these are more effective than others.
Now I feel that I should point out that while I am a keen supporter of using natural cures to treat baldness where possible, sometimes hair loss may be indicative of an illness of which hair loss is an actual symptom. For this reason, if you are suffering from hair loss it's a good idea to see a doctor, just in case your hair is a symptom of some illness. When this issue has been cleared, you can with confidence check out the various types of natural hair restoration therapies, which are available.
