Question

Why does my hair take longer to dry when I use conditioner?

Answer 1

All conditioners leave a residue on your hair.  For example, if you use one for dry and brittle hair it'll leave a moisurizing agent.  When you use conditioner it's leaving that residue on it and it takes longer to dry because it's keeping in moisture.

Answer 2

Because it's moisturized.

Answer 3

Because conditioner is used to add moisture to your hair so once you have used it, your hair will hold on to water better and longer than without it.
