Winter causes the hair and scalp to dry out due to the low relative humidity in the air, which leads to more water loss from our skin and hair (transcutaneous water loss). This dryness can cause more itchiness and increased flaking (dandruff). The condition is also aggravated by a decrease in the frequency of shampooing with an even lower temperature, which leads to scale buildup. This is why many people notice a worsening of their dandruff (seborrheic dermatitis) during the winter. Seborrheic dermatitis is aggravated by the increase in Malassezia colonies during winter. Few of the medical conditions known to cause itching and flaking are atopic dermatitides, seborrheic dermatitis, and psoriasis. These conditions are often worse in winter. However, if we acquire certain practices we can avoid dry and itchy scalp in winter. These are the following:
The priority is to keep the body hydrated by drinking plenty of water regularly. Also, increase your probiotics; They strengthen the immune system that helps the body fight fungal infections that cause dandruff or dry scalp. Also, drink at least eight glasses of water a day to improve your scalp health and future hair growth.
Regular lubrication (olive oil, coconut oil) can also help reduce transdermal water loss; however, lubrication generally aggravates seborrheic dermatitis, so people with this condition should avoid lubrication. Better to grease before shampooing. Lubrication with essential oils can also help reduce dryness and itchiness, which are generally not greasy.
Hair should be shampooed regularly at least twice a week. Shampoos that contain laurel or Laureth sulfate provide a better cleaning but also cause more dryness. If you are using this shampoo, it is best to follow it up with a conditioner. People who have a thick and flaky scalp or an oily scalp should use this type of shampoo. Shampoos that contain natural oils and moisturizing agents like panthenol can be used for people with normal scalps. This shampoo causes less dryness, but also less scrubbing. Using a shampoo with an ideal pH (4.5-6.0) reduces the secretion of serine proteases that can cause an itchy scalp. Itching can also be reduced by using a shampoo or lotion that contains menthol or camphor.
Overuse of beauty and thermal treatments such as hot tongs, straighteners and blow dryers should be avoided: Hot styling products should not be used on the scalp at all. Make sure to retain these tools away from your scalp when using them. Heat styling tools remove all moisture from your hair, leaving it dry and brittle.
Stress has an effect on many aspects of our health and well-being. While stress does not cause an itchy scalp, it can aggravate symptoms.
