Detangling hair when it is dry is not recommended as it can cause hair breakage and damage.
Dry hair is more fragile and prone to breakage than wet hair. When the hair is wet, it is more elastic and can stretch without breaking, making it easier to detangle.
Additionally, wet hair is easier to manipulate and style as it is more pliable than dry hair.
If you need to detangle your hair and it is dry, it is best to apply a leave-in conditioner or a detangling spray to help loosen the knots and make the process easier. Using a wide-toothed comb or a brush specifically designed for detangling can also help prevent breakage.
It's important to be gentle when detangling and avoid pulling or tugging at the hair. It's also recommended to start detangling from the ends of the hair and work your way up to the roots, as this can help minimize tangles and reduce breakage.
