A yeast called Candida causes most scalp yeast infections or candidiasis. Candida can grow and thrive in warm, damp environments. Your scalp has a natural balance of yeast and bacteria.

When this happens, Candida has the opportunity to collect. Conditions that allow Candida to grow include:

• Hot and humid climates.
• Certain personal grooming products that contain harsh chemicals.
• Small cuts on your scalp that provide an entryway.
• Follicular occlusion syndrome: When your hair follicles become blocked by keratin, a protein in your hair. When the follicles get blocked, they rupture and cause inflammation.
