Is it safe to use a laser to remove red spots (such as veins and NOT hair removal) on the scalp? Will the laser penetrate the scalp and reach my brain? May seem like a crazy question, but I can't find an answer elsewhere. Thank you.
No, it is not going to reach your brain. You can find answers with the help of a local certified plastic surgeon.
Laser for small vascular or vein removal can be done on your scalp without any side effect with your brain.
