Most people just give their hair a once-over with shampoo and conditioner to keep it clean, however, can "double shampooing" produce better outcomes and healthier hair?
“This hair-washing method is exactly what it sounds like — if someone double shampoos, they'll wash their hair with shampoo twice during a single shower session,” Brendan Camp, MD, a board-certified dermatologist at MDCS Dermatology, told Health.
“Deciding whether to double shampoo your hair is dependent on several factors, including hair type, activity level, and personal hair care needs,” said Melanie Palm, MD, a board-certified dermatologist and cosmetic surgeon at Art of Skin MD.
Notably, double-shampooing can help a lot of people secure their hair.
"So this deeper clean can be especially helpful for people with curly or coarse hair or anyone who frequently goes without washing their hair for several days," Palm told Health.
“People who do not shampoo often will notice that shampooing twice makes their hair feel cleaner because it is more effective at removing oils and residue than shampooing once,” Camp added.
While double shampooing is meant to clear the hair and scalp of buildup and oil, using conditioner twice likely won’t have the same effect, Camp said. In fact, it could “mitigate the effects of double shampooing,” he explained.
