Will a safety razor prevent ingrown hairs and razor burn?

It sure can. Since a single-blade (safety razor) cuts your hair at skin level, there are fewer chances of hair regrowth getting trapped below the epidermis, the surface of the skin. When hair has to struggle through your follicles, it causes irritation of those very follicles, resulting in itchy, inflamed regrowth. Ingrowns occur when that blunt hair gets trapped in the follicle and curls back under the skin. This happens less with a safety razor because it never cuts the hair below the surface of the skin to begin with. The rest is up to you, and it's rooted in skincare- especially for us curly people. Help your skin thrive by exfoliating and moisturizing.
