Hi! So sorry for what you are experiencing. I started taking Tagrisso in Feb 2023. I had the bumps / rash on my face and they gave me hydrocortisone cream and an antibiotic gel (Clindamycin) to use simultaneously - this helped on my face. Now they are on my scalp with a vengeance - bumps and welts that are sore and itchy. When I finally think I got those under control new ones pop up. I have tried different shampoos - narrowed it down to a daily wash alternating between Ketoconazole and T/Sal and Clobetasol liquid scalp application. Tried steroid foams prescribed by my dermatologist and they did not work. I have shoulder length thick hair and I am about to cut it all off. I would appreciate input too if anyone has this issue. Wishing you all relief!
