How to handle scalp itch during fall and winter? 5 common causes you must know!

2024-11-18|Lena

Many people experience the inevitable scalp itch as soon as fall and winter arrive, especially around the nape area. Scratching often results in flakes showing up for everyone to see, which can seriously affect social interactions. When faced with a "snowy" scalp, the immediate solution often seems to be washing the hair more frequently in hopes of eliminating the flakes. However, excessive cleansing can actually worsen the problem. This article will help you understand the causes of scalp itch during seasonal changes and provide tips on how to improve and manage the symptoms effectively.

Why does scalp itch increase during fall and winter?

The most common symptoms are "seasonal itch" and "dry season itch." As autumn arrives, changes in temperature and humidity lead to cooler, drier air, which reduces moisture levels in the scalp and skin. Sweat and sebaceous gland activity also decrease. Without the protective barrier of natural oils, the scalp and skin are exposed to cold air, causing the pores to contract suddenly. This leads to sensitivity, dryness, and itching on the scalp and skin.

Seasonal Scalp Itch Causes - Temperature Changes and High Water Temperature

Temperature changes and hot water

The large temperature fluctuations between day and night during fall and winter can stress the scalp, alternating between sweating and cooling, which can lead to dryness and itching. Additionally, using overly hot water during showers in colder weather can strip the scalp of its natural oils. Without this protective barrier, moisture evaporates more quickly, leaving the scalp dry and prone to itching.

Seasonal Scalp Itch Causes - Skin-Related Conditions

Skin-related conditions

If scalp itch persists for several weeks and is accompanied by severe dandruff, redness, or peeling, it may be caused by underlying skin conditions. Common conditions include atopic dermatitis, seborrheic dermatitis, and scalp ringworm. These issues often result in itching, along with dandruff, redness, and flaking of the scalp. For severe cases, it is recommended to consult a dermatologist for treatment. Over-scratching can lead to broken skin and infection, worsening the condition and making recovery more challenging.

Seasonal Scalp Itch Causes - Improper Shampooing Frequency

Inappropriate shampooing frequency

Both over-washing and under-washing your hair can cause problems. The frequency of shampooing should be based on your scalp's oil production. Many people mistakenly believe that dandruff is caused by improper cleaning and turn to harsh cleansing shampoos, which can lead to over-cleansing. Over-cleansing can strip the scalp's protective lipid barrier, making the skin drier and potentially increasing dandruff. For those with dry scalps and low oil production, it is recommended to wash hair every 2–3 days.

Seasonal Scalp Itch Causes - Frequent Hair Dyeing or Allergic Reactions to Dye

Frequent hair dyeing or dye allergies

Frequent hair dyeing or allergic reactions to ingredients in hair dye can cause symptoms such as itching, burning sensations, redness, swelling, and stinging on the scalp. If these symptoms occur, or if there are existing wounds on the scalp, it is best to stop dyeing immediately. Persistent itching and scratching can lead to bleeding, and further contact with dye can worsen the condition. For first-time hair dye users, it is recommended to ask the stylist to conduct an allergy test before proceeding.

Seasonal Scalp Itch Causes - Shampoo Residue or Use of Unsuitable Shampoo

Shampoo residue or inappropriate shampoo use

If shampoo is not rinsed thoroughly, leftover foam can block hair follicles, leading to mild itching or, in severe cases, significant hair loss. Additionally, using a shampoo that doesn’t match your scalp type can also result in itching. For example, randomly picking a shampoo from the store might cause scalp itching the same evening; using oil-control shampoo for a seemingly oily scalp, only to find it still greasy the next morning; or switching to anti-dandruff shampoo but seeing no improvement even after a week. These scenarios are likely caused by using an unsuitable shampoo.

How to alleviate scalp itch issues

If using a newly purchased shampoo causes scalp itching, it likely means the wrong product was chosen. Many shampoos on the market contain chemical irritants, which can cause discomfort, especially for those with sensitive skin. Selecting a shampoo tailored to your scalp's needs is crucial to break the cycle of irritation. Beyond choosing the right shampoo, the washing process itself is also critical! Avoid scrubbing your scalp with fingernails; instead, use your fingertips to gently massage the scalp to prevent scratches. The water temperature should be warm enough to feel comfortable on your wrist but not hot. When rinsing, take your time—rinse thoroughly for at least three minutes, paying special attention to the area at the nape of the neck, which is often missed.

In addition to proper washing techniques, maintaining the cleanliness of personal items is essential. Dirty items like towels, helmets, hats, and pillows can harbor bacteria and contribute to scalp itchiness. Internal factors such as irregular sleep patterns, a stimulating diet, and excessive stress can also lead to scalp discomfort. If scalp itching persists for several months without improvement, consider seeking help. You can consult your hairstylist for a scalp care treatment or visit a dermatologist for professional assistance.

Other scalp problems caused by seasonal changes

Seasonal temperature changes can easily cause the scalp to dry out, especially for those with sensitive scalps who feel the effects more intensely. Alongside itching, dandruff is one of the most bothersome symptoms during seasonal transitions. Dandruff is present year-round, but temperature fluctuations during seasonal changes disrupt the scalp's oil balance and surface metabolism, exacerbating the issue. Hair loss is another common concern during this time. Dry skin with insufficient moisture prompts increased sebum production, which can clog hair follicles and, in severe cases, lead to folliculitis. When excessive oil blocks the pores, the hair strands fail to absorb nutrients, causing the hair roots to weaken and thin, eventually resulting in hair loss.

Recommended MCG shampoos

Lin Dong Shampoo

Cleanses the scalp while maintaining an oil balance, reducing the discomfort caused by an oily scalp. During use, it surrounds you with a refreshing mint fragrance, and the cooling sensation of mint helps relax scalp tension. Its aroma also neutralizes the unpleasant odor associated with oily hair.

Dry scalps often suffer from tightness due to moisture loss, leading to fine, flaky dandruff. For dry scalps, the key is to "avoid over-cleansing." Opting for shampoos with moisturizing and repairing ingredients is the first step to effectively addressing the issue.
