Can someone please tell me what this is…

Based on your description of dry, flaky skin on the scalp accompanied by redness, itching, and burning when applying lotion, your symptoms might align with scalp psoriasis—a common skin condition. Psoriasis causes rapid skin cell buildup, resulting in dry, scaly patches that can be itchy and sometimes painful. Managing scalp psoriasis involves gentle care and avoiding irritants. Using medicated shampoos containing coal tar, salicylic acid, or zinc pyrithione can help reduce scaling and inflammation. Moisturizing the scalp regularly with fragrance-free lotions or oils designed for sensitive skin may ease dryness, but be cautious if certain products cause burning or irritation. It's important to avoid scratching, as this can worsen symptoms or lead to infection. Wearing soft, breathable hats can reduce irritation from environmental factors. If over-the-counter treatments are ineffective, a visit to a dermatologist is recommended. They may prescribe topical corticosteroids or other medications tailored to your condition. Remember, scalp psoriasis is a chronic condition but can be managed with the right routine and medical guidance. Monitoring symptoms closely and adjusting care as needed will help maintain scalp health and comfort. If you notice worsening redness, swelling, or pain, seek professional advice promptly.
