There is a lot of dandruff on the hairline

The height of the hairline determines the width of a person's forehead, and people can often infer a person's scalp care by the condition of the hair around the hairline and the health of the scalp. Some people find that there is a lot of dandruff around their hairline, which directly affects the overall beauty of their hairstyle. In addition, there is a lot of dandruff around the hairline, which makes people look unclean. So what causes this?

Tinea capitis is a superficial fungal infection of the scalp and hair. It can be divided into three types: yellow ringworm, white ringworm and black dot ringworm according to the pathogens and clinical manifestations. It is common in children and is highly contagious, easily spreading among children in nurseries, kindergartens, primary schools and families. It is mainly transmitted through contaminated hairdressing tools, and can also be transmitted through contact with cats, dogs and other livestock suffering from ringworm.

Causes

1. Cause of the disease: Tinea capitis is a disease caused by fungal infection of the scalp and hair. If you suffer from tinea capitis, many gray-white scales or large yellow scabs will appear on your scalp, and it may also cause your hair to break or fall off. In severe cases, the hair becomes uneven or even almost gone, which is what people call "baldness". Tinea capitis is mainly transmitted through contact with patients with tinea capitis or sick animals, and it is extremely rare to be transmitted from nature. Normal people can be easily infected if they have close contact with people with tinea capitis, especially children playing together and touching heads with each other. There are also cases where one becomes sick after contact with sick animals, which are also direct transmissions. If you use hats, headscarves, pillows, combs, hair clippers, scissors, etc. used by patients with tinea capitis, you may also be infected. This is called indirect transmission. It can be seen that tinea capitis is very contagious. In the past, tinea capitis was very prevalent in our country, and patients with tinea capitis could often be seen in hospitals. However, fungal infection does not necessarily cause tinea capitis, which is related to the body's resistance to fungi. Most adults have stronger resistance to fungi, while children have weaker resistance, so tinea capitis is more common in children.

2. Pathogenesis A suitable environment of the host skin is very important for the development of dermatophytosis. In addition to trauma, the increased moisture soaking the skin is also conducive to the growth and reproduction of dermatophytes. Non-breathable clothing can increase local temperature and humidity of the skin and interfere with the barrier function of the stratum corneum. After dermatophytes invade the skin, they go through several stages of development, including an incubation period, enlargement during the infection-fighting process, and a regression period.

Symptoms: When the metabolic cycle reaches about 5 days, ulcers will appear on the scalp because the new scalp cells are not yet mature. They are generally round, red and swollen, with a small bump in the center of the circle. Scalp ringworm usually only occurs on the scalp, but in severe cases it may spread to behind the ears, cheeks or chest.

Topical treatments

(1) Topical antifungal herbal cream: Apply to the entire scalp.

(2) Washing your hair: Use 2% ketoconazole lotion or hot water soap to wash your hair once every night for 2 months.

(3) Shaving: All diseased hair should be cut off or burned as much as possible, once a week, for a total of 8 times.

Systemic treatment

Griseofulvin is still the first choice and is the most sensitive to Microsporum. Adults: 0.6-0.8 g/d; children: 15-20 mg/(kg?d), taken in 3 divided doses after meals. The course of treatment is 3-4 weeks. During medication, eat more oily foods to promote drug absorption. At the same time, pay attention to liver function tests. If griseofulvin is used together with the Chinese medicine Artemisia capillaris, its efficacy can be improved and the dosage of griseofulvin can be reduced. And avoid using drugs that inhibit gastric acid secretion. Ketoconazole is most sensitive to Trichophyton tonsurans. The dosage for children is 5 mg/(kg?d), taken once, preferably during meals, and the course of treatment is 4 to 8 weeks. Itraconazole is taken with meals, 0.2 g/d for adults and 0.1 g/d for children, once a week for 4 to 6 weeks. Terbinafine 0.25g/d, children 0.125g/d, take for 4 to 8 weeks. Liver function tests should also be paid attention to during medication. In the acute phase of kerion, small doses of corticosteroids can also be used for a short period of time.
