I'm sorry to hear about the sudden hair loss on your eyebrow. This can understandably be concerning.

Based on the information about Topifort-NX Topical Suspension you have been using, it contains a combination of corticosteroid (Clobetasol), antifungal (Clotrimazole), and antibacterial (Neomycin) agents. While it helps treat infections and reduce inflammation, it can sometimes cause side effects such as skin irritation, redness, itching, or thinning of the skin, which might contribute to hair loss in the treated area.

Here are some important points and recommendations:

• Stop using the topical suspension on your eyebrow immediately to prevent any potential worsening of irritation or side effects.
• Hair loss localized to one eyebrow could be due to an allergic reaction, irritation from the medication, or possibly an insect bite as you mentioned.
• Avoid scratching or rubbing the area to prevent further damage.
• Keep the area clean and avoid applying any other topical products unless advised by a doctor.
• If you notice worsening redness, swelling, pain, or if hair loss continues or spreads, seek evaluation promptly.
• It is important to consult a dermatologist who can examine the area, determine the exact cause of hair loss, and recommend appropriate treatment.

If you experience any signs of severe allergic reaction such as swelling of the face, difficulty breathing, or intense pain, seek emergency medical care immediately.
