How Often Should You Wash Your Hair? The Ultimate Guide for Healthy Hair & Scalp! (2025)

Let's talk about a topic that might seem mundane but is actually crucial for your hair and scalp health: how often should you wash your hair? It's time to uncover the secrets to a healthy scalp and discover the ideal hair washing routine for you.

While some might view hair wash day as a chore, it's an essential step in maintaining scalp health, which is often overlooked. The buildup of dirt and even our natural hair oils can lead to clogged pores on the scalp, potentially causing infections. But here's where it gets controversial: the frequency of hair washing varies depending on several factors.

Melissa DeZarate, a renowned hair stylist, suggests washing your hair every three to four days in an ideal world. However, she emphasizes that the bare minimum should be once a week. If you want to extend the time between washes, DeZarate recommends using scalp scrubs or detox shampoos to keep your scalp healthy.

Dr. Christina Weng, a board-certified dermatologist, highlights that the frequency of hair washing depends on factors like hair texture, length, diet, and environment. Simone Kogen, another celebrity hair stylist, agrees, adding that hair type also plays a significant role.

For those with fine hair, more frequent washes are necessary as it tends to accumulate grease and buildup more easily. On the other hand, thicker, coarser hair distributes moisture more evenly, requiring less frequent washes.

Dr. Weng recommends rinsing your hair with water more frequently, especially for those with thin hair. She suggests doing it five to six times a week, while those with thicker hair can get away with two to three times a week.

But why is scalp health so important? Well, when you wash your hair less frequently, there's more time for sebum (oil) to accumulate, and its composition changes once exposed to air. This oxidation can lead to skin irritation, inflammation, and even microbial or fungal overgrowth.

DeZarate, Kogen, and Dr. Weng all stress the importance of focusing on scalp health when shampooing. If you notice redness, flaking, excessive greasiness, thick buildup, or breakouts, it's a sign that you need to wash your hair more often. It's crucial to find the right balance for your unique hair and scalp needs.

Kogen recommends using scalp-specific products designed to cleanse the scalp and remove impurities, rather than just focusing on the hair strands. Dr. Weng agrees, emphasizing the importance of massaging products into the scalp and letting them sit before rinsing.

However, it's possible to wash your hair too much. DeZarate warns that washing hair more than once a day, along with deep conditioning, can overhydrate the scalp, leading to breakouts and bumps.

Ultimately, the experts agree that the most crucial aspect is paying attention to how your scalp feels. It's a delicate balance, and finding the right frequency for your hair type is key.
