Dry Spots That Come and Go
Pityriasis rosea, though less common, can show up on the scalp as a large dry patch followed by smaller ones.
What Helps:
Use moisturizing, calming lotions.
Avoid scratching to reduce irritation.
In most cases, it clears up on its own within a few weeks.

Steps to Take:
See a dermatologist for an accurate diagnosis.
Follow a full course of oral antifungal medication and use specialized shampoos.
Continue treatment even after symptoms fade to prevent recurrence.
