These are little white bulbs from the root of your naturally shed hairs. You really can’t do a whole lot to change them aside from brush out your locks to remove them.
Most people won’t notice them. We even have a little tag talking about them on the blog! Check it out here!
You can just ignore them. They aren’t a bad sign, and some people have them while others don’t. I had them in my locks. They’ll always be there but they aren’t a problem.
