In the habit of sleeping with wet hair? Here's a few reasons why you should reconsider.

1. When your hair is wet, it's at its weakest and most fragile state. Thus it is the most susceptible to breakage. When you sleep, the friction of your hair on your pillow as you toss back and forth can cause already frail hair to snap and break off.

2.  Chances are you'll wake up with unruly and knotted hair which will require more work with hot tools to fix and straighten it out in the morning.

3.  Most styling products are heat-activated, which means if you're spritzing on a thickening spray or root lifter while your hair is wet and then going to bed, you're basically just adding dead weight to your strands. (Not to mention wasting your hair products.)

On the off chance that you end up with a wed head before bed, there are a few things you can do to lessen the after-effects. First, try sleeping on a silk pillowcase which will allow hair to glide easily across it without any tugging or pulling. Apply product at the roots and then hit it with a hair dryer for a few minutes to activate it. Lastly, put hair in a loose braid or bun as to prevent tangles.
