What is a recommended method for barbers to minimize skin irritation from shaving?

Using a pre-shave oil or cream is a highly recommended method for minimizing skin irritation during shaving. These products are designed to soften the hair and create a protective barrier on the skin, which helps reduce friction and provides a smoother glide for the razor. This is particularly beneficial for individuals with sensitive skin, as it can significantly decrease the likelihood of nicks, cuts, and irritation that often accompanies shaving.

While other methods such as applying aftershave lotion can help soothe the skin after shaving, they do not prevent irritation during the shaving process itself. Shaving against the direction of hair growth can actually increase irritation and lead to ingrown hairs. Additionally, using hot water is often indicated for opening pores and softening hair, but it requires careful temperature management and may not be as effective as the direct lubrication offered by pre-shave oils or creams. Thus, pre-shave oils or creams stand out as the best preventive measure.
