Does washing hair aggravate hair loss in alopecia areata?
The causes of alopecia areata are complex and mostly related to individual factors, so ordinary hair washing generally does not exacerbate the condition. The main factors are still linked to a decrease in personal immunity, genetic inheritance, lack of vitamins and trace elements in the body, or long-term consumption of spicy and stimulating foods, frequent staying up late, anxiety, tension, and poor mood. However, frequent hair dyeing or perming, and the use of hair products with strong irritants such as hair gels and conditioners, may aggravate the symptoms of alopecia areata. Once this disease occurs, it is essential to seek treatment at accredited medical institutions. With long-term persistence, it is entirely possible to cure the disease completely.
What is seasonal skin allergy?
Seasonal skin allergies are allergic reactions of the skin triggered by allergens that occur during specific seasons. For example, in spring, pollen allergies might lead to dermatitis, eczema, or urticaria; in summer, the intense ultraviolet rays can cause solar dermatitis, and in the cold weather of autumn and winter, cold urticaria or allergic dermatitis might occur. These conditions only appear during specific seasons and generally ease off or disappear after the season ends without the need for treatment. These are characteristics of seasonal skin allergies. In such cases, it is advisable to regularly exercise to boost the immune system to fight against allergens, avoid spicy and irritating foods, and refrain from staying up late.
What should I do if a sebaceous cyst recurs?
Sebaceous cysts are tumors formed by the accumulation of excessively secreted sebum from the sebaceous glands in localized areas. These cysts contain a substance resembling tofu dregs and mostly develop in areas with active sebaceous gland secretion. Generally, surgical removal is often completely effective. If the condition recurs, it indicates either significant local inflammation or incomplete removal during surgery. In such cases, it is advisable to visit a dermatology department at a reputable hospital for another minor surgery to ensure complete excision of the cyst sac. Additionally, it is important to maintain a proper diet and lifestyle, avoiding spicy and irritating foods, refraining from staying up late, and avoiding public baths and swimming pools. It's also advisable not to keep small animals at home.
What causes alopecia areata?
The causes of alopecia areata are varied, and the specific factors for each individual may differ. However, it is mainly related to reduced immunity, lack of vitamins and trace elements, long-term consumption of spicy and irritating food, frequent staying up late with anxiety and tension, and poor mood. Some teens may also develop alopecia areata if they frequently suffer from scalp folliculitis, abscesses, or cysts, which can damage the hair follicles. Only a small number of cases may be related to genetic inheritance. Therefore, once this condition occurs, it is essential to seek treatment at a formal medical institution. With long-term persistence, it is possible to cure the condition, and adopting good dietary and lifestyle habits can help with the treatment.
Genital herpes is what kind of situation?
Genital herpes is caused by infection with the herpes simplex virus and is classified as a sexually transmitted disease (STD). It primarily occurs after sexual contact, although infection can also happen through contact with contaminated towels or bed sheets. Initially, small blisters appear on the external genitalia, accompanied by a burning sensation and pain. Once the disease manifests, it is contagious and can be transmitted to others through sexual contact. It is crucial to seek prompt treatment at a reputable hospital upon discovering this condition. Standard antiviral medications can cure it, but the virus cannot be completely eradicated once contracted. When immunity is low or after consuming spicy and irritating foods, the disease may recur in the genital area and become active again. Therefore, it is essential to avoid sexual contact during an outbreak to prevent repeated cross-infection.
Genital herpes is what?
Genital herpes is a disease caused by infection with the herpes simplex virus type 2, which is a type of sexually transmitted disease. It is mostly transmitted through direct sexual contact. Initially, small blisters appear on the genital area, which can cause burning or pain. Most patients will gradually recover on their own within about a week, and can also recover quickly with oral antiviral medication. However, the virus is not completely eliminated and once infected, it cannot be completely eradicated. The virus is carried for life. When one's immune system is weakened, there is a possibility of recurrence of the condition. Therefore, if such a disease occurs, it is essential to seek proper treatment and, during an outbreak, try to avoid sexual contact to prevent transmission to others.
How to determine if you have contracted genital warts?
Genital warts appear as cauliflower-like growths and continuously increase in size and number. This disease is a sexually transmitted infection (STI), spread through sexual contact. If one has had unprotected sexual encounters, or notices new growths in the genital area, anus, or mouth that gradually increase in size or number, it is possible that these are genital warts. In such cases, it is best to visit a dermatology department at a reputable hospital and perform an acetic acid white test for diagnosis. Once diagnosed, it is crucial to receive proper treatment, as the warts can proliferate and potentially be transmitted to others through sexual contact. The overall treatment period for this disease tends to be lengthy, involving both laser treatment and medication.
Is scabies chickenpox?
Scabies is caused by an infection of scabies mites and is highly contagious, generally being transmitted through direct contact, such as sharing clothes or sleeping in the same bed with shared bedding. Typically, the itching is milder during the day and worsens at night. Symptoms include itching, peeling, and blistering between the fingers. In males, red scabies nodules may appear on the scrotum. Chickenpox, caused by the varicella-zoster virus, is also highly contagious but primarily spreads through droplets and air. Once infected, it can be treated with antiviral medications. Scabies and chickenpox are entirely different diseases and must be diagnosed and treated separately.
Can tinea cruris heal by itself?
Tinea cruris is caused by fungal infection. This disease is highly infectious and recurrent, and it will not heal by itself without formal treatment. Instead, the affected area will become larger and the infection will become more severe. It may lead to fungal infections on the buttocks and even other parts of the body. It is recommended to apply antifungal cream twice a day. The treatment should be extensive and prolonged, and the area of application should be large. During the treatment period, it is beneficial to use sulfur soap for local washing, expose the area to air frequently, and keep it dry and ventilated, as these measures can help to completely eliminate the deep-seated fungi. Avoid public baths and swimming pools, try not to keep small animals at home, and if you do, maintain good hygiene, especially disinfecting and exposing undergarments to sunlight frequently.
The likelihood of sebaceous cysts turning cancerous
Sebaceous cysts are localized hypersecretion of sebaceous glands that form benign proliferations on the skin surface after mixing with bacterial infections. They generally form a sac under the skin containing tofu-dreg-like substances. Sebaceous cysts do not become malignant, and clinically, these diseases almost have no possibility of malignancy. Once discovered, it is essential to first get a diagnosis and then treatment at the dermatology department of a standard hospital. The most common treatment method is surgery to directly remove the tofu-dreg-like substances and the sac. If left untreated, the cyst may grow larger or rupture, leading to re-infection, which can be problematic.
