<s>[INST] I have researched hair loss and found a number of interesting things. One of which was scalp injections. I had alopecia on my beard...odd place however it grew back after an injection. My hair is very thick however if I compare a square inch on the side to a square inch on the crown it is 50% thinner. So the question is ....is there any injectable that would promote hair growth at all, and if so any risk of making things worse ? [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.Intralesional injections are used for a particular kind of hair loss known as Alopecia areata. For other types of hair loss, injections can make things worse. Please consult your dermatologist to confirm whether you have alopecia areata or androgenetic alopecia. Please do not self medicate.Hope I have answered your query. Let me know if I can assist you further. </s>
