Dry shampoo has helped out big time in my life. If you've hit the snooze button a few too many times or have a last minute date, dry shampoo has been just the thing to take your lifeless greasy hair to clean and voluminous in minutes. The difference between dry shampoo and dry conditioner is that dry shampoo gets rid of the oils while dry conditioner adds in oils to moisturize. Just like dry shampoo, it comes in a dry form and there is no water needed.
Dry conditioner isn't just an option if you need a quick fix between washes. It can be used if you have extremely dry or damaged hair and to combat frizz.
