Think about it: the starch in dry shampoo mops up excess oil and dirt, but then it just sits there, making your scalp a prime breeding ground for bacteria. Plus, if you already struggle with scalp conditions like dandruff, dryness or flaking, too much powder can make these conditions worse.
Plenty of trichologists and dermatologists suggest thinking about the skin on our head (ie the scalp) like the skin on our face. And just as we regularly scrub our face for a deep clean and to unclog pores, we should also be exfoliating our scalps to remove dead skin cells, product and dry shampoo buildup, and stimulate blood flow. Doing this once a month can help promote a healthy environment for healthy hair growth. Which is what we all ultimately want.
