I had a prp therapy for my hair and today my forehead is swollen is it something to worry about?

In my opinion, your forehead is swollen because of trauma to the scalp. This sometimes occurs due to an aggressive PRP treatment or one which uses extensive  multiple punctures or micro-needling. It should resolve within a few days.If not, return to your doctor. Sleep on a couple pillows,keep  head elevated and don't eat any salty food. Avoid drinking alcohol. Hope this helps. Good luck.

If you do prp on your scalp then yes you can certainly get swelling that dissipates after 48 hours. The lack of sleep has so many variables as to why that's happening, stress, alcohol intake, anxiety, eating a heavy a meal at night, too much tv and cellphone and blue light exposure to affect your rem sleep...it's hard to point it to prp only....

A little swelling on the forehead is common after PRP injections to the scalp. The swelling should dissipate in about 48 hours. If you have concerns, please consult with your injector. Best, Dr. Emer
