How would you go about making the hair under your leg invisible?

I know what you are talking about, I believe it happens to almost all women when they shave.

To prevent those little black dots from showing, what I do is soak my legs in warm to hot water for about 5 to 10 minutes before I start shaving. This help open up pores and hair follicles, so you can get a closer shave. Then, I rinse my legs in cold water after I shave them to close up the pores and follicles.

It really helps to moisturize your legs before, during, and after shaving to prevent those little black dots, and keep your skin feeling smooth and soft. Moisturizers like Aloe Vera are great to use between and after shaving and moisturizing shaving gels/creams should be used during shaving, which will help you get a smoother/closer shave.

Also, to prevent those little black dots, you should use a really good, clean, and sharp razor. Those cheap disposable razors with one blade aren’t going to give a close shave. Shave with razors that have at least three razors, and make sure they’re not dull.
