Why is Soap is not good to wash your hair because soap?

Soap isn't great for washing hair because it's too harsh. It has a high pH (alkaline), which strips away your hair's natural oils, making it dry, brittle, and dull. It can also leave a residue that makes hair feel sticky or heavy. Shampoos are gentler and designed for hair.

Examples:

Using bar soap (like dish soap or laundry soap) can make your hair feel rough and tangled.

A shampoo, like one for dry hair, cleans without stripping oils, keeping hair soft and shiny.
