How to improve hair loss and a receding hairline?
For hair loss and receding hairlines, timely symptomatic treatment should be conducted to improve symptoms. The treatment for a receding hairline should vary based on different causes. For cases caused by endocrine disorders, excessive secretion of neurohormones, vigorous secretion of sebaceous glands, or genetic factors, a dermatoscopy can be performed to make a clear diagnosis. Then, visit the endocrinology department, and treat according to the lab results. If the scalp is very oily, selenium disulfide shampoo can be used for washing, and topical minoxidil solution can be applied. If the hair loss is due to seborrheic alopecia, also known as androgenic alopecia, anti-androgen medications should be administered timely, such as finasteride tablets, spironolactone, etc. If the local hair follicles have already caused significant atrophy and noticeable recession, hair transplantation can be considered as a method to improve the hairline by transplanting hair.

How long does it take for a deep second-degree burn to heal?
Second-degree burns generally require three to four weeks to heal. The healing time for burn wounds depends on the depth of the burn. Second-degree burns include both superficial partial-thickness and deep partial-thickness burns. Superficial partial-thickness burns involve blistering of the upper dermis. The blisters are relatively full, and the base of the wound is red and moist with substantial exudation. There is significant swelling and severe pain. Under non-infected conditions, superficial partial-thickness burns generally heal within two weeks without scarring. Deep partial-thickness burns affect the deeper layer of the dermis. Blistering in this case tends to be relatively flat, and the base of the wound appears red and white, sometimes showing a net-like pattern of vessel thrombosis. These wounds have less elasticity and the pain is less intense. Deep partial-thickness burns generally take three to four weeks to heal and leave scars. Therefore, formal anti-scarring treatment is required after healing of a deep partial-thickness burn.

What are the causes of female hair loss?
There are genetic factors at play, with androgenetic alopecia being the most common form affecting both men and women. In men, the hair follicles in the balding areas are more susceptible to the effects and attacks of androgens, along with sensitivity causing the hair follicles to progressively shrink and eventually turn into vellus hair follicles, leading to clinical hair loss, folliculitis, stress, and anxiety, as well as smoking. Postpartum, some autoimmune diseases are also associated with androgenetic alopecia, including other autoimmune factors, exemplified by alopecia areata. Some patients with alopecia areata may also have other concurrent autoimmune diseases, such as goiter, Hashimoto's thyroiditis, vitiligo, etc. Excessive mental stress or sudden shock can also cause alopecia areata, telogen effluvium, and other types of hair loss.

What should I do if scratching itchy skin causes more bumps?
Skin itching and bumps can increase with scratching; treatment can include oral antihistamines, traditional Chinese medicine, and topical creams. Skin itching and bumps are generally caused by allergies, which could be urticaria or eczema. Patients can take oral antihistamines such as mizolastine sustained-release tablets, loratadine tablets, chlorcyclizine tablets, etc., and combine them with traditional Chinese medicines such as Skin Disease Blood Poison tablets and Heat-Clearing Dampness-Removing granules. While taking medication, topical corticosteroid creams such as Compound Dexamethasone Cream and Fusidic Acid Cream can be used. Patients with skin itching should avoid spicy, greasy foods, and fishy foods to prevent exacerbation of symptoms.

What are the early symptoms of syphilis?
Syphilis is divided into overt and latent syphilis. Latent syphilis, regardless of whether it is early or late stage, shows no symptoms at all and can only be confirmed by blood testing. The symptoms in the early stage are mainly those of overt syphilis, primarily manifestations of primary syphilis. The stages of primary, secondary, and tertiary syphilis begin with the appearance of a lesion at the site of infection, typically about 0.5 to 1 centimeter in diameter, with a hard, dark red nodule that feels like cartilage. The surface may have ulcers; it may be painless, or there may be no pain at all. Subsequently, nearby lymph nodes may become enlarged. This swelling of the lymph nodes is characterized by being painless, usually unilateral, with no redness or rupture. These are the clear symptoms of overt primary syphilis. If treated properly at this stage, recovery is generally rapid.

How long will it take for hair follicles to necrose after hair loss?
Hair loss for about half a year can lead to the death of hair follicles. The death of hair follicles is usually caused by folliculitis, which is due to damage or blockage of the follicles, leading to redness, itching, and pain in the center of the follicle, appearance of papules and pustules, and in severe cases, ruptured pustules that crust over and form permanent skin damage, such as scars and hair loss. Therefore, it is crucial to seek medical attention promptly upon signs of folliculitis. Diagnosis can be confirmed through physical skin examinations, laboratory tests, and pus examination. Timely treatment usually involves the application of topical antibiotics like Mupirocin ointment, topical corticosteroids such as Budesonide ointment, and for patients with poor response to topical medication, ultraviolet light treatment of the infected area may be chosen. (Medication should be used under the guidance of a doctor.)

Can washing your hair with vinegar cure tinea capitis?
Washing the scalp with vinegar for tinea capitis can only play a minor treatment role and cannot cure it. Tinea capitis is a skin disease caused by fungal infections and requires treatment with antifungal medications. For example, topical application of clotrimazole cream or terbinafine cream can be used, along with antifungal shampoos such as selenium sulfide shampoo or ketoconazole shampoo. Patients with severe tinea capitis may also need oral medication treatment, such as taking itraconazole capsules or terbinafine tablets. It is advisable not to self-medicate tinea capitis, and systematic treatment should be sought at a hospital.

How is hyperhidrosis of the hands and feet treated?
The patient suffers from palmar-plantar hyperhidrosis, which can be treated using antiperspirants or botulinum toxin injections. Palmar-plantar hyperhidrosis is primarily about controlling sweat secretion and is caused by a disorder in the sympathetic nervous system function. In treatment, antiperspirants used mainly contain aluminum salt compounds, such as 20% aluminum chloride. It should be used according to the doctor's instructions, every three to five days. Typically, dryness and flaking of the skin occur after using the medication, and timely skin care is necessary. Botulinum toxin injections can also be used to treat palmar-plantar hyperhidrosis. Botulinum toxin can inhibit the action of acetylcholine at local nerve endings, which also has a therapeutic effect on local hyperhidrosis. Moreover, the effect lasts relatively long, maintaining about six months.

How to deal with big toe paronychia on your own?
The patient with an ingrown toenail managed it themselves, requiring minimized activity and elevating the foot to promote local circulation. Additionally, topical disinfectants such as iodine tincture can be used, not merely applied, but used for moist dressing. Take some cotton soaked in iodine tincture and apply it to the swollen area around the nail fold, generally recommending a five to ten-minute application. Antibiotic ointments can also be applied externally, such as mupirocin cream. After application, cover it for two hours, and treat it two to three times a day. If this method does not effectively alleviate the pain, consider taking antibiotics that have previously caused no allergies, with a preference for cephalosporins or penicillin-type antibiotics. If the antibiotics still do not effectively relieve the pain, it is advised to seek medical attention at a hospital. (Use medications under the guidance of a doctor.)

How long is the incubation period for sexually transmitted diseases?
The incubation period of sexually transmitted diseases (STDs) varies, which is a rather general question. Firstly, it is important for patients to understand what STDs are; they are a collective term for sexually transmitted infections, consisting of various diseases such as HIV/AIDS, syphilis, genital warts, and gonorrhea, which are among the most common. STDs share a common characteristic of being transmitted through high-risk sexual behaviors. Typically, the incubation period for syphilis is 40 to 90 days, for HIV it is about three months, genital warts can have an incubation period ranging from three months to half a year, and gonorrhea tends to manifest symptoms quickly. Once infected with gonorrhea, symptoms such as abnormal discharge, discomfort during urination, frequent urination, urgent urination, and painful urination may appear within a week. Therefore, if one engages in high-risk sexual behaviors and wishes to be reassured through testing, it is advisable to visit a hospital for a medical examination after a week.
