**Core Concept**
Tinea capitis, also known as ringworm of the scalp, is a fungal infection that affects the hair follicles, leading to hair loss, inflammation, and scalp irritation. This condition is more common in children and can be contagious.

**Why the Correct Answer is Right**
The correct diagnosis of tinea capitis is supported by the presence of boggy scalp hair that is easily pluckable, which indicates an inflammatory process at the hair follicle level. The recurrence of symptoms after 6 months suggests a fungal infection that requires antifungal treatment. Griseofulvin is a first-line treatment for tinea capitis, as it targets the fungal infection and promotes hair growth.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option may be tempting, but it is not the correct treatment for tinea capitis. Topical corticosteroids may provide temporary relief from inflammation but do not address the underlying fungal infection.
* **Option B:** This option is incorrect because it does not address the fungal infection directly. While antibiotics may be used to treat secondary bacterial infections, they are not the primary treatment for tinea capitis.
* **Option C:** This option is not the correct treatment for tinea capitis. Topical antifungals may provide some relief, but they are not as effective as oral antifungal medications like griseofulvin.

**Clinical Pearl / High-Yield Fact**
It's essential to note that tinea capitis is a contagious condition, and close contacts of the affected child should be screened and treated if necessary. Additionally, griseofulvin treatment should be continued for at least 6-8 weeks to ensure complete clearance of the fungal infection.

**Correct Answer:** D.
