What Is Itching?
Itching is a sensation that occurs when certain things touch your skin. It triggers you to move your hands to the area and scratch it. While this seems to be a very basic and spontaneous reaction, it is actually your body’s way of protecting you from insects and other foreign bodies. Not everything that touches your skin requires you to itch it away. For instance, your clothes are in constant contact with your skin, and you don’t feel the need to itch. This is because your brain does not perceive clothes to be a threat to your skin. A special group of cells called inhibitory spinal neurons helps in differentiating what is and what is not a threat. These neurons transmit signals between your brain and skin and help to determine what is a potential threat (1). Now that you know the science behind the simple itch, let us look at why do you feel itchy after shower and what are some of the potential causes?
What Causes Itchy Skin After Showering Or Bathing?
Feeling Itchy after shower can be caused by something as benign as loss of moisture after a shower or it could be a sign of something much more serious. Let us find out further.
Dry Skin
Studies show that soap strips the skin of its essential oils and has a disruptive effect on the barrier function of the skin. Soaps also tend to have sodium lauryl sulphate (SLS) which is known to be a potential skin irritant and may cause dermatitis. The same study also showed that using soap to wash the skin and using a towel to dry yourself may further increase the dryness of your skin (2).
Xerosis
Long hot showers or baths during the winter may cause Xerosis, making the skin dry and itchy. It is a condition that decreases the sebum levels in the skin. Sebum is an oily substance produced by the sebaceous glands that keep the skin moisturized. In some cases, xerosis can also cause painful cracks on the skin (3), (4).
Aquagenic Pruritus
This is a very rare skin condition that causes intense itching when your skin comes in contact with water. The itching can begin immediately and can last for up to an hour or more. Legs, arms, chest, back, and abdomen are the most commonly affected areas (5). Taking a shower or a bath is inevitable and it is a part of your hygiene routine. Hence, it may be extremely difficult if you have to deal with itching after shower every time you take a bath. So, how do you manage this? Find out in the next section.

Using Essential Bath Oils
Studies show that using bath oils when taking a shower can help protect the skin’s barrier function and may help in preventing dry skin (8). Make sure you dilute these essential oils with soothing carrier oils like jojoba oil before applying them to your skin. Exercise caution if you have sensitive skin as fragrances can cause irritation.
