<s>[INST] I am a male, 58 years young and in good health and shape and about 30 minutes ago after I got out of the shower I noticed an indentation on my forehead from the top of my scalp to the middle of my forehead! What is this, what caused it and how can I get rid of it ASAP?! Thank you. [/INST] Hello, Welcome to HCM. If you did not bang your head, you probably have it for some time. You should see a plastic surgeon who might correct it with Botox injection or with filler. If it is not correctable with these,  you may require plastic surgery. </s>
