There are a lot of factors to consider when it comes to detangling in the shower. Some people swear by it, while others will adamantly label it as a no-no.
No Two Heads of Hair Are The Same
LengthyHair.com does not take a stance on this issue as there are too many factor involved and no two heads of hair are the same. Your hair length, texture, and thickness will all play a role.
If you have straight hair and it tangles minimally, detangling in the shower might be a breeze! However, someone with thick tightly curled hair may find detangling outside of the shower with a spray bottle more effective.
Water is Your Friend
With that being said, the pressure of the water in the shower, a great conditioner with slip, and working in sections will make detangling easier.
