I have sensitive oily skin that would love me to never shave again. However, I'm not quite ready for the 19th century mountain man look, so I have to use sensitive skin shaving and skin products, as well as change my razor blades often. Even then I get ingrown hairs every week or so. I use Anthony logistics Ingrown Hair Treatment twice a day, even when I don't have any ingrown hairs. It helps to prevent and treat the few that I get. I won't say it will completely prevent users from getting ingrown hairs, but it will make them less frequent and serious. The package is a pump dispenser, which is a little sensitive at first, so I have to be careful not to dispense too much. Right now, a can lasts a month and a half or so.
