Final answer:
Selsun Blue works by inhibiting fungal growth on the scalp, helping to treat and prevent conditions like dandruff and seborrheic dermatitis.
Step-by-step explanation:
The mechanism of action of Selsun Blue is related to its active ingredient, selenium sulfide. Selenium sulfide works by inhibiting fungal growth on the scalp, which helps to treat and prevent conditions such as dandruff and seborrheic dermatitis.
When applied to the scalp, selenium sulfide reduces the production of dandruff-causing fungi by disrupting their cell membranes and inhibiting their growth. This action helps to control the symptoms of dandruff and reduce flaking.
It is important to note that Selsun Blue should be used as directed and may not be suitable for everyone. It is always recommended to consult with a healthcare professional for appropriate use and advice.
