Why washing your hair too often is a mistake, dermatologist warns

Frequent hair washing may seem like the perfect answer to greasy locks, but leading dermatologists are raising a critical flag on this common practice. The truth is that overwashing can do more harm than good, stripping away natural oils that protect the scalp and hair. Excessive washing may lead to serious issues like hair dryness, breakage, and even scalp inflammation. Dr. Heather W. Goff, a prominent dermatologist, underscores that these concerns extend beyond aesthetic frustration; they can affect overall scalp health and hair vitality. Understanding the frequency that works best for your unique hair type is crucial for sustaining its strength and shine.

Many individuals wrestle with their hair’s appearance, often feeling pressured to reach for shampoo more frequently, especially if they notice oil buildup. However, Dr. Goff advocates tailored washing schedules based on hair texture. For instance, curlier hair, which tends to be drier and more fragile, should ideally be washed no more than once a week. Those with finer hair may find washing every two to three days is preferable to maintain a healthy scalp without triggering conditions like seborrheic dermatitis. As 2026 unfolds, these insights remind us that hair care should be just as personalized as skincare routines.

Understanding Hair Types and Washing Frequency

Your hair type significantly influences how often you should wash it. Curlier hair often benefits from a more extended routine between washes due to its vulnerability.

The Impact of Overwashing on Hair Health

Overwashing can lead to an array of issues, primarily because it strips hair of its vital sebum. This protective layer, essential for maintaining hydration, becomes depleted with each wash. Dr. Goff illustrates this with a relatable analogy: “If you wash your jeans every day, they’ll eventually wear out.” Similar principles apply to hair, where daily washing can lead to hair damage, making it brittle and prone to breakage. This cycle not only affects the aesthetics of your hair but can cascade into lasting impacts on its health.

Addressing Hair Loss Concerns

Many people wonder if regular washing can cause hair loss prevention. Dr. Goff reassures that hair shedding during washes is normal and often reflects hairs that were ready to fall out. On average, shedding between 50 to 100 hairs daily is considered healthy. However, if you experience unusual hair thinning, consulting a dermatologist is advisable to rule out any underlying conditions.
