This may appear to be self advertisement but you can check out this website www.trichohaircare.com.my for some info on hair loss causes and treatment.

While we do not normally comment on forums, there are many reasons for hair loss. Some are not yet well understood like MPT and AA, one caused by androgens and the other by auto-immune response. These 2 are the most common genetic related conditions but not the only. Fungal and bacteria infection are another cause and where treatment is not provided immediately, hair loss is often permanent due to tissue scaring. There may be also behaviour and pyschological reasons for hair loss, such as compulsive hair pulling, bad hygiene, head dress or caps. Covering your hair all day and not washing your hair at the end of it can lead to fungal and bacteria infections. Scalp disorders, malnutrition, poisoning, illness, drugs and pregnancy are other causes of hair loss. Hair perms or hair chemical can also damage your hair resulting in hair loss. Of course this list is not the concise list.

It is best to consult a doctor familiar with hair loss problems or a trichologist if you have hair loss. Hair loss is not only a condition but an important symtom in diagnosis of some illnesses. A doctor or trichologist would be able to tell the difference between a symtom or just a genetic condition. Often a blood test, medical and physical examination, even a hair mineral analysis or a hormonal lab test is needed for a proper diagnosis. We often work closely with doctors and dermatologist to diagnose and treat patients. If we suspect illness as a cause, we usually recommend the patient see a doctor to have the suspected illness verified before putting the patient on any treatment.

As for products, both topical and supplements, they are as good as the diagnosis and if you are not certain, it is often a hit or miss scenerio at best. But generally we do not recommended self treatment as many products contain harmful substance that may be absorbed through the skin and accumulate in the body. Quite often this leads to kidney or liver problems or hormonal imbalance. And too much calcium can be a problem of its own. And if you really insist on self treatment, do see a doctor to have a blood test and medical examination every 6 months and keep a health diary, writing down any symtoms that you may encounter while you are on these products and stop if something unusual appears. Always establish a health baseline first.

Hope this helps.

BTW I am not the trichologist, just a friend of the trichologist. The information above is just regurgitated but proof read.
