Why does one get, and what can be done for, tiny blond hairs on top of, and on the sides of, the nose?

Your blonde hairs can not be laser treated; however, electrolysis may be a very good permanent hair removal option for this nose area.  Electrolysis is more time consuming than laser treatments but a very good option for small areas, like the nose.  From your comments, you would also benefit from an aesthetician consult to get on a very good custom home skin care regimen and some in office procedures to improve your pores!  

For the first time, it is now possible to use laser hair removal to permanently destroy light and white colored hairs such as yours on your nose . A new product called Melaser has just been introduced into the United States that has been scientifically proven, in a study just published in the “Journal of Drugs in Dermatology”, to be the first of its kind to allow lasers to successfully destroy the follicle in light-colored hair. Melaser is a melanin-containing solution that, when combined with micro-needling the skin to enhance its penetration, stains the hair follicle, making it a “target” for the laser light energy. Melaser is currently being marketed in the US by the micro-needling company ProCell Therapies.
