Root Stimulator

i have hairloss in my crown area and recently started using a root stimulator product and ive noticed small bumps in that area. could this be new hair emerging?

I don’t know what you mean by “root stimulator” (it may be a marketing term, not a medical term), but new hair growth usually does not present like that. What is usually called hair growth, seen with available hair loss medications such as topical minoxidil (Rogaine) or oral finasteride (Propecia), is thickening of the miniaturized hair. The effects of these medications are to stop or slow down the rate of hair loss or sometimes to thicken the current (miniaturized) hair. Check this with your dermatologist if you see new bumps in your head.
