I found this on my son’s scalp. I have no idea what it is and we can’t get a doctor’s appointment right now. Do you have any advice?

This guide summarizes common scalp conditions, especially psoriasis vulgaris, a common but often misunderstood condition. You’ll learn how to recognize scalp psoriasis, try simple home remedies, explore over-the-counter options, identify warning signs, and effectively document symptoms for your doctor.

1. Understanding Scalp Conditions

The scalp is a sensitive area that can develop a variety of problems, from mild dandruff to chronic skin conditions. Genetics, hygiene habits, the environment, and infections all play a role. For example, seborrheic dermatitis often causes greasy flakes and redness due to an overgrowth of yeast. Folliculitis, an infection of the hair follicles, results in the appearance of red, pus-filled bumps. Because many scalp conditions exhibit similar symptoms, an accurate diagnosis is essential to guide treatment.
