Fungal infections are commonly called ringworm. However, they are not caused by worms. They are superficial infections of the skin, hair or nails caused by a variety of fungi which otherwise live in the soil, on animals, or sometimes only on people. Begins as a small pimple which spreads outwards, leaving a scaly hairless patch. Then, infected hair starts thinning and breaks off easily.
There are several ways to treat or avoid fungus in your hair. However, the first and basic step is good hygiene.
The fungus in the hair can be contagious. This means that an infected person can pass it on to others via objects or direct contact. For this reason, avoid sharing towels, combs, and brushes and make sure that all heads and objects that come in contact with the hair are clean, rinse well, clean and dry before use and make it a habit of cleaning all your items at least once a week.
Be sure to go to control with a dermatologist every 6 months, to make sure everything is fine and that the skin is in a healthy state.
You should nourish hair with anti-fungal shampoo. Shampoos contain ingredients that can kill most fungi in your hair.
Avoid wearing hats that can lead to excessive sweating on the scalp.
