Selenium Sulfide
What is Selenium Sulfide?
Selenium sulfide is an antifungal agent primarily used to treat dandruff, seborrheic dermatitis, and certain fungal infections of the skin, such as tinea versicolor. It works by slowing the growth of the yeast that causes these conditions. Selenium sulfide is commonly found in over-the-counter and prescription shampoos and lotions such as Selsun Blue.
How does Selenium Sulfide work?
Selenium sulfide's mechanism of action includes:
Antifungal Activity: It disrupts the metabolic processes of specific fungi, preventing their growth and proliferation.
Reducing Skin Cell Turnover: By decelerating the rapid turnover of skin cells, it reduces symptoms like flaking and scaling commonly seen in conditions like dandruff or seborrheic dermatitis.
What are possible side effects of Selenium Sulfide?
While many people tolerate selenium sulfide well, some potential side effects include:
Skin irritation or dryness
Hair loss or hair discoloration
Greasy or oily scalp or skin
Changes in hair texture
More severe side effects, although rare, might include:
Rashes, hives, or itching
Swelling, especially of the face, throat, or tongue
Severe dizziness
Trouble breathing
How is Selenium Sulfide used?
The use of selenium sulfide varies based on the condition being treated. For conditions like dandruff or seborrheic dermatitis:
