Dandruff is one of the most annoying non-contagious conditions that tends to increase with climate change, especially during the fall and winter seasons. It becomes visibly present on the scalp and spreads to the shoulders and back, causing constant itching, and starts to decrease relatively as summer approaches. While dryness may be a valid reason, there are several other factors that contribute to this bothersome condition.
Here are some reasons for the increased appearance of dandruff during the winter:
1. **Dry Skin**: Dryness makes it difficult to produce enough oils for the scalp, leading to dandruff, especially in winter.
2. **Infrequent Hair Washing**: Not washing the hair often in winter causes oil buildup on the scalp and results in dandruff.
3. **Oily Hair**: Seborrheic dermatitis leads to redness of the skin and the appearance of white flakes.
4. **Poor Nutrition**: Dandruff can be a result of following a specific diet that lacks the nutrients that hair needs, such as zinc and vitamin B.
5. **Certain Diseases**: Conditions such as eczema, psoriasis, or yeast infections (malassezia), or allergies from certain hair care products can also lead to dandruff.
