Secondary syphilis, which causes hair loss
If you first become infected with syphilis and don't treat it, it will attack you another time with different symptoms altogether and is called secondary syphilis. Syphilis is a disease caused by spiral bacteria. The disease is transmitted through direct contact with a person who has a chancre (a sore caused by syphilis). These chancres usually appear on the genitals, the reason why it is a sexually transmitted disease. However, chancres can also appear in the mouth and lips. In the first phase of syphilis it does not cause hair loss,...

Secondary syphilis, which causes hair loss
If you first become infected with syphilis and don't treat it, it will attack you another time with different symptoms altogether and is called secondary syphilis. Syphilis is a disease caused by spiral bacteria. The disease is transmitted through direct contact with a person who has a chancre (a sore caused by syphilis). These chancres usually appear on the genitals, the reason why it is a sexually transmitted disease. However, chancres can also appear in the mouth and lips. In the first phase of syphilis, it does not cause hair loss unless the hair happens to be where the chancre is. If the disease is allowed to progress to the next stage, it will result in hair loss. We will look at secondary syphilis, which causes hair loss.
In the secondary stage, syphilis is characterized by skin rashes and lesions on the mucous membranes. These rashes can find their way to the scalp where they can form inflammation on the hair follicles. This affects the hair follicles and makes them so itchy that you may scratch the hair out yourself. The rashes can also be responsible for damaging the hair follicles and compromising the integrity of the hair shafts, thereby causing hair loss. The hair loss associated with syphilis occurs in patches and does not follow a specific pattern. The lesions of this secondary infection contain bacteria that infect other people when they come into contact with the lesions. Secondary syphilis needs to be treated as soon as you notice it based on its secondary symptoms. If left untreated, the disease continues and progresses every time, so the result can be death as syphilis can be fatal.
As soon as you discover that you have syphilis, you must immediately consult a doctor so that you can be prescribed medication that will help kill this deadly bacterial disease. Syphilis treatment involves the use of some antibiotics. Once you have treated the disease, there is a chance that damaged hair follicles will recover and hair patches will show signs of hair growth. If the hair follicles have been severely damaged, they can be treated so that they can continue to produce hair and remove hair spots.
Common treatments for hair loss due to syphilis include medications such as finasteride and minoxidil. These two medications have been approved by the FDA and have been proven effective in bringing even the most dormant hair follicles back into the hair production cycle. The good part of using these medications is that they come in the form of topical creams and capsules, so you do not need to undergo any surgical procedures while treating hair loss problems with these medications. Secondary syphilis, which causes hair loss, cannot be diagnosed by sight. This means that some scalp flakes will need to be collected and tested for bacterial activity so that the doctor can properly diagnose the cause of your hair loss.
