Those with fine, thin or straight hair should be cautious when using dry shampoo. If you have ongoing scalp problems, like dandruff or dermatitis, it's best to avoid dry shampoo to help control the problems, Blaisure says.
Watch out for the aforementioned controversial ingredients and remember that moderation is key. Don't use dry shampoo as a styling aid, Dotson says. Use a sea salt spray for tousled strands and dry shampoo for managing grease.
Applying too much of anything can weaken hair follicles. Less is always more with dry shampoo, Philip B. says. "You really just want a light coating. Focus on the first few inches of hair at the roots, not directly at the scalp," he says. "Then the brush becomes the vehicle to disperse the product well and give strands that perfect Hollywood finish." Use a natural boar bristle paddle brush, like the Raincry Large Condition Paddle Brush, $115, to move the product and oils down the hair shaft.

The experts suggest using dry shampoo occasionally and ensuring the scalp is being cleaned thoroughly after approximately two to four days to prevent too much buildup. Regular cleansing with shampoo is key because inflammation and hair loss can occur when dry shampoo buildup remains on the scalp. "Remember, skin is a living organ and needs care to stay healthy," Blaisure says. "No one would think to keep their makeup on for a week — scalp skin is the same."
To combat any drying effects of dry shampoo, Diersen suggests pairing dry shampoo with a protecting oil, like Chi Rose Hip Oil Color Nurture Dry UV Protecting Oil, $9.97.
