How Often Should You Wash Your Hair?

The "best" system for hair washing completely depends on your hair type and the condition of your scalp. Although many dermatologists recommend washing your hair two to three times a week to avoid product buildup and scalp irritation, it can vary. 

Hair Type

According to dermatologist Iris Rubin, MD, finer and straighter hair types (types 1-3) typically need more frequent washing than coarser and curlier textures (type 4). Sophia Emmanuel, Trichologist and Cosmetologist, explains that "with type 4 hair, natural oils don’t easily travel down the strand due to tighter curl patterns, so shampooing once a week is sufficient, but on the other hand, for straighter and finer hair types, oils accumulate and spread more easily along the hair strands, which means they often require cleansing up to three times a week or every other day."

And if you have a protective style in, wash day is also important. "Cleansing your scalp is the only way to ensure your protective style is supporting healthy hair," says Jeanne. "This wash routine is usually spaced out a little longer than traditional wash day." The type of shampoo or cleanser you use may vary depending on your style. "Hair extensions, box braids, twists with hair added in are some styles that can be washed with the style in because you have access to your scalp," explains Emmanuel. "Other protective styles, such as crochet braids, can be more challenging to wash depending on the type of hair that is used and limited scalp access." But the frequency at which you cleanse should also be based on what your scalp and hair strands are telling you. 

Scalp Conditions

If you’re experiencing any itching, flaking, product buildup, greasy strands, or unpleasant smells, you may want to consider cleansing more often. "Regular shampooing up to three times a week helps manage dandruff, itching, and helps control sebum production," says Emmanuel. "If you do not have a scalp condition or an active lifestyle, you can shampoo your hair once a week."

Is it okay if I wash my hair every day?

It's okay to wash your hair every day, as long as you're not stripping your hair and causing dryness. Think about it: You wash your face every day (or twice a day) without fail to wash away the dirt, grime, and gunk. The same could go for your scalp. Especially if you have straight, fine hair.

Keep in mind, though: If you do shampoo daily, you’ll want to make sure to use a mix of gentle cleansers to prevent scalp dryness, irritation, and itch. For example: If you can’t stretch your washings to every other day, you can cleanse up daily with a gentle shampoo that’s filled with nourishing ingredients (like hyaluronic acid and aloe vera), then, once a week (for one wash only!), swap in a clarifying shampoo to break down oils and hard water buildup. We have all our favorites below.

And if you are washing every day, make sure you’re replenishing your hair’s moisture each time with deep conditioners, hair masks, and/or leave-in conditioners to keep your hair from drying out from the water (yes, water itself can actually be drying!). You’ll also want to avoid heat-styling as much as possible—so no blow-drying after your daily showers—or you’ll strip and damage your strands, leading to dull, brittle hair over time.
