## Too Frequent or Rare Washing One of the main reasons is an incorrect cleansing routine. Washing too often can dry out the scalp, causing it to produce more sebum. However, infrequent cleansing leads to the accumulation of dirt and accelerates oiliness. ## Wrong Shampoo Products that do not suit the scalp type can exacerbate the problem. Heavy, nourishing shampoos designed for dry hair often weigh down the roots and make them look dirty within just a few hours. ## Excessive Hair Care Products Masks, oils, and conditioners can overload the hair when applied incorrectly. Especially if they are applied close to the roots — this is one of the most common mistakes that causes hair to lose volume and freshness more quickly. ## Frequent Touching of Hair The habit of constantly touching your hair also affects its condition. Oils and dirt from your hands easily transfer to your hair and scalp. ## Hot Water and Aggressive Drying Water that is too hot stimulates the sebaceous glands. A similar effect can be caused by intensive blow-drying at high temperatures — the scalp responds with increased sebum production. ...Rapid loss of hair freshness is not a sentence, but a signal to reconsider your hair care. It is enough to adjust basic habits: choose suitable products, change washing techniques, and reduce aggressive exposure. In most cases, this is sufficient for hair to remain clean and well-groomed for longer.
