Hello~They are probably lice, however, to be sure, I would see a dermatologist and have them looked at. There are creams and shampoos for them that are supposed to be effective, ask your pharmacist.
Here is a natural way to get rid of them:
Lice can be killed quickly, easily, cheaply and safely with mayonnaise. Simply get a new jar of mayonnaise from your kitchen shelf or at the grocery store. (Don’t grab one from the refrigerator, as it will be way too cold.) Grab a handful (or several) and cover all of your hair, being sure to get behind the ears and down the neck a little. You can cover this with a plastic shower cap to keep the mayonnaise from dripping or getting onto your furniture. Leave the mayonnaise on for two hours to smother the lice and developed eggs. Then, remove the shower cap and throw it away, wash your hands good with soap, and shampoo the hair thoroughly. It may take two or more shampoos to get the hair clean.
You can use Vaseline if you don't have any mayonnaise. The only way to remove Vaseline from hair is to saturate the hair in baby oil, rub in through the hair completely, then squeeze out as much as you can. Then wash the hair three times with Dawn dish soap and hot water (not hot enough to burn!), each time leaving the dish soap on for a few minutes to allow it to work.
Vaseline can be left on overnight if you wish, but this is not safe with mayonnaise.
If you don’t trust the mayonnaise or Vaseline to smother the lice, you can make a natural lice shampoo to kill the lice. To a base of five teaspoons of Olive Carrier Oil (or coconut oil), add five drops of Tea Tree Essential Oil, five drops of Rosemary Essential Oil, five drops of Lavender Essential Oil, five drops of Peppermint Essential Oil, and five drops of Eucalyptus Essential Oil. Add a small amount of regular shampoo to the mixture, and put this all over the hair - all the way to the edges. Leave this on for an hour under a towel or tight-fitting shower cap to prevent drips. Rinse the hair, and shampoo the hair. (Olive oil and coconut oil kill lice by "dissolving" their exoskeletons, and other oils will not have the same effect.)
Don't use a conditioner at this stage, but you will find that the hair is very easy to comb after using this oily mixture.
I would expect this to be lice. There are shampoo and creams that are affective. There is a special comb that can be used but this for after treatment. Look for LICE on the package.
