What technique should barbers avoid when conditioning hair?

Over-conditioning hair is a technique that barbers should avoid because it can lead to several issues that negatively impact the hair's health and appearance. When hair is over-conditioned, it becomes excessively soft and lacks the necessary structure, which can lead to it feeling limp and lifeless. This condition can also weigh the hair down, making it look greasy and unclean rather than shiny and healthy.

Proper conditioning is about achieving the right balance; a conditioner should help nourish and hydrate hair without overwhelming it. It's essential for barbers to assess each client’s hair type and needs when applying conditioner, ensuring that they provide the right amount without tipping into over-conditioning.

In contrast, under-conditioning may leave the hair dry, but it is a more common challenge that can be corrected easily with a proper treatment regimen. Applying conditioner directly to the scalp is something that can clog pores and lead to scalp issues, while using conditioner on dry hair is typically not the intended method, as conditioners are designed to be used on wet or damp hair to effectively penetrate and hydrate.
