There are a number of reasons why you should avoid washing your hair on a daily basis.
Signs of over-washing include an increase in split ends and excessive dandruff.
Your hair should be washed much less frequently, than your skin - usually not on a daily basis. It may be tempting to shampoo and condition each morning, especially if your hair easily becomes greasy, but doing so can cause many issues including stripping your scalp of many essential oils.
"There isn't an exact number of times you should wash your hair a week," celebrity stylist Tonya Le told Insider. "It depends on your hair texture, your natural oil production, etc. But paying attention to the little signs your hair is giving you can help you come up with the best washing schedule."
Woman who went gray 'overnight' at age 21 says she feels sexier than ever at 43 now that she has stopped trying to dye her locks and embraced a natural silver 'do
Mother-of-two Sara Eisenman, from Sedona, Arizona, said her hair started to turn silver when she was just 21 years of age in what seemed like 'overnight'.
Le added, "If you want to take care of your hair's integrity, remember that it can naturally take care of itself. Of course giving it a tiny little push of man-made products won't hurt a bit, just as long as you're using the correct products for your hair type and, most importantly, using those products correctly as well."
Unsure if you're washing too often? Insider spoke to Le to determine five clear signs that you need to give your hair a shampooing-break.
If you highlight or dye your hair, examining how long the color stays vibrant and strong will show if you're washing too much. It's also important to use a shampoo and conditioner made specifically for color-treated hair.
"Wash hair about three-four times a week with correct shampoo and conditioner/mask made for color-treated hair," Le told Insider. "And in-between washes, refresh your hair with a dry shampoo of your choice."
This Woman Turned Traction Alopecia Into a Lesson In Self-Care
How Lisa Williams, 42, learned to be nicer to herself-and her hair. I started losing my hair back in high school when I was 18 years old. I was a cheerleader and track runner, which meant I wore my hair pulled back in tight ponytails regularly. And I mean tight. If my ponytail wasn’t so tight that my eyes looked slanty, it wasn’t perfect, and I wanted my hair to be perfect. The irony, of course, is that my hair started thinning, especially near my temples and bangs.
Your hair is dry and frizzy.
Washing your hair too often can also impact the texture of your hair.
"A total lack of moisture from stripping oils can also cause a dry, flaky scalp and as your scalp dries out so does your hair," she said.
Le added, "Hair becomes flatter and also begins to lack shine too, so [you should use] moisturizing styling products that will help restore the hair cuticles by making them more soft, manageable and, most important, luscious.
"If you seem to be getting more split ends than usual, this could also be a sign of over-washing. Wet hair is so extra susceptible to damage and breakage, so the more you wash it, the more opportunity it has to break," Le told Insider.
Your hair has lost all shine.
Because over-washing strips the scalps of oils, it will also make your hair appear to be less shiny.
"Shiny hair is healthy hair. So if your hair has no shine, it could mean your hair is not moisturized. Shampoo washes away your natural oils leaving the inner layer unprotected. Or even using too much shampoo can cause residue build up - not pretty."
Do hair vitamins really work? Here’s what a dermatologist says.
"This happens when the scalp gets a tad too dry and starts to flake," Le told Insider. "So minimizing your shampoo sessions will help give your oil glands a chance to do their job and soothe the scalp naturally. If dandruff [gets] too intense, a scalp exfoliating treatment along with a tea tree oil scalp treatment will take care of it. And make sure to continue using a dandruff shampoo until flakes clear."
