Generally speaking, Groover explains that you want to invest in a shampoo that is going to effectively cleanse the hair and scalp without stripping any natural oils or leave behind residue. This may mean opting for a sulfate-free shampoo, or perhaps paying extra attention to the ingredient list to ensure the formula contains elements that are beneficial for your hair type of scalp concern.
How often should I wash my hair?
“How often you shampoo your hair varies by hair type,” explains Groover. “Fine hair with oily scalps should shampoo hair every one to three days, for example.” On the other hand, those with natural hair, who tend to have thicker and drier strands should shampoo anywhere from once a week to biweekly. “The maximum wait time for shampooing is 10 to 14 days depending on hair texture and scalp condition,” she adds.
But while it’s vital to ensure your hair is properly cleansed on a regular basis, it’s also important to not overdo it—even if your scalp tends to be on the oilier side. “Regardless of hair or scalp type, washing too much can strip the hair’s natural oils leaving it brittle and prone to breakage or damage,” warns Nozile. “It can also lead to dry scalp.” In turn, this can cause irritation, flaking, and itchiness.
How to shampoo properly
A good general rule of thumb to keep in mind while cleansing your hair is that shampoo should be first targeted at the scalp, then worked down the hair shaft to remove any product build-up.
“For oily scalps it’s best to make sure you really get down to the roots and lather it in well with your finger tips to help break up excess oil,” advises Nozile. “For anti-dandruff shampoos, it’s good to do the same, but make sure to let it sit for five to ten minutes before rinsing out.” This ensures the formula has time to work its magic. For dense hair, Groover recommends parting the hair into four sections, then cleansing each segment one-by-one to ensure a thorough wash.
Can shampoo promote hair growth?
Nozile says that while some shampoos have the ability to make the hair appear fuller and thicker, there’s no evidence to prove it can actually trigger growth—unless you use a shampoo with minoxidil. However, “technically it can help decrease hair loss, which can be interpreted as promoting hair growth,” he says. Plus, Groover explains that “hydrating, moisturizing, and strengthening shampoos provide properties that promote length retention. Clean hair and scalps provide a good environment for growth.”
