Hello,
For such itchy spots on the body, tinea corporis is an important possibility and for hair, tinea capitis may cause such symptoms of itching and hair loss. Tinea capitis is contagious and can spread after direct contact with someone who has the condition, or if you touch contaminated items such as combs, hats, clothing, or similar surfaces. Diagnosis is by clinical examination of the scalp, KOH examination of the skin scrapings as well as a skin lesion biopsy with microscopic examination.
I would suggest a dermatologist’s for the same.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I should have said dermol cream, i look forward to any response, i can upload photos if needs be
