How Often Should You Really Wash Your Hair in Winter? The Answer May Surprise You

Washing hair in winter requires more consideration than sticking to any kind of strict schedule. There is no universal rule that stipulates whether a person should wash his or her hair one, two, or three times a week, since the condition of scalp skin in winter differs greatly from the way it is in other seasons. Low humidity, increased heating indoors, and low temperatures all can have an impact on the condition of the scalp.

According to the results of the study conducted by the Journal of Clinical and Aesthetic Dermatology, cold weather can decrease skin hydration and lead to impaired barrier functioning, making one's skin itchy and irritated. Thus, the results obtained by researchers working for the National Institutes of Health show that even healthy skin behaves differently during winter.

This is why one should wash hair depending on the condition of the scalp.

A dry scalp may need fewer washes

Individuals who suffer from dry and irritated scalps should avoid over-shampooing since the act may only aggravate symptoms through the stripping of natural oils. The use of hot water or harsh cleansers is also likely to exacerbate conditions further.

According to a scientific paper featured in Skin Research and Technology, daily washing of hair was observed in women who cleaned once or twice daily. These subjects showed an increase in transepidermal water loss compared to those who did it every third or fifth day.

If individuals experience dryness, they should consider extending washes to reduce any potential pain. Specialists recommend paying close attention to symptoms like itching and flaky but not oily scalps. It could be a sign that the individual washes their hair more than necessary.

Washing fewer times during winter may help individuals maintain their scalp health.

Dandruff changes the equation

Dry scalp and dandruff tend to be confused with each other, although, according to dermatologists, this cannot be the case. Dandruff and seborrheic dermatitis are associated with inflammation and the activity of fungi, which often requires active treatment.

It is at this point that frequent washing could become beneficial. According to clinical reviews, two washes a week with ketoconazole shampoo have been established as the standard during flare-ups. Randomized studies included washing with an anti-dandruff shampoo three times a week as a symptom control measure.

It can thus be concluded that cutting down on shampooing in winter may not always be effective. Should the flakes be accompanied by excess sebum, itching, or reappearing irritation, the use of medicated shampoos could be recommended.
As can be seen from dermatological literature, it depends rather on the state of the scalp, not on the season.

Hair type also affects frequency

How frequently you should wash yourself during the colder months also varies depending on your hair texture and habits. Those with curly or coily hair might wash themselves less often in order to prevent breakage and dryness, and this has been deemed acceptable by professionals.

According to a review by dermatologists specializing in scalp disorders within skin of color, published by the National Institute of Health, there are many instances where women who have protective hairstyles wash themselves at least every two weeks. This needs to be taken into account when planning their treatment regimen.

And why? Because it is often more beneficial to adhere to actual practices than follow strict guidelines. If one has oily straight hair, washing will be necessary. If one has a dry scalp and textured hair, washing less frequently would probably suit him/her.

So what is the right winter rule?

The evidence does not point towards one specific number. There is an underlying need for balance.
In case you experience irritation, sensitivity, or dryness during cold weather, washing your hair less frequently can help ensure the skin stays comfortable and healthy. In the case of dandruff and seborrheic dermatitis, following the prescribed washing schedule may matter more.

According to Rick Hanson, Ph.D., writing in Psychology Today, body stress increases whenever normal regulation becomes disturbed, and this is how the situation with your skin's health works, too. A balanced approach is generally better at ensuring your resilience.

This is why a symptom-based regimen is recommended by specialists today. You should wash your hair frequently enough to manage oily roots and flaking. But do not wash so frequently that your scalp feels irritated. Depending on your needs, this could be anything from washing once or twice weekly to washing daily.

A good regimen in the winter is not defined by either frequent or infrequent washing. It is defined by keeping your scalp comfortable.
