Why is my wool blanket so itchy?

Wool blankets are a great addition to any bedroom during the winter season. They are warm, cozy and durable, and provide the perfect insulation for cold nights. However, some people may experience a problem with their wool blanket being itchy. While wool is known for being soft and smooth, scratchiness can occur due to a variety of factors. If you’re wondering why your wool blanket is so itchy, there are several reasons why this might be the case. In this article, we will explore some of the common causes of wool blanket itchiness and provide tips for alleviating discomfort.

1. Fiber coarseness

One of the main reasons wool blankets can be itchy is due to the coarseness of the fibers. The finer the wool fibers, the softer the blanket will be. However, some wool fibers can be more coarse and scratchy than others, depending on the breed of sheep they come from. For example, the wool of Merino sheep is much softer and finer than the wool of Romney sheep. If you find that your wool blanket is particularly itchy, it could be due to the breed of sheep the wool came from. In this case, choosing a blanket made from a finer wool fiber or a wool blend can help reduce itchiness.

2. Chemical processing

Wool fibers need to be properly cleaned and processed before they can be used in the production of blankets. Unfortunately, some manufacturers may use harsh chemicals during the processing phase that can cause itchiness and irritation. These chemicals can include chlorine, bleach, and other detergents that strip the wool of its natural oils and protective layer. If you suspect that your wool blanket is itchy due to chemical processing, you can try washing it with a gentle, natural detergent and avoiding the use of dryer sheets or fabric softeners when laundering.

3. Natural lanolin content

Lanolin is a natural wax that is found in sheep's wool. It is used to help protect the sheep's skin and coat from the elements. Some people may have an allergic reaction to lanolin, which can cause itchiness and irritation when using wool products. If you suspect that you are allergic to lanolin, choosing a wool blanket that has been carefully processed and washed to remove the lanolin can help reduce itchiness.

4. Rough texture of the fibers

Another reason why your wool blanket may be itchy is due to the rough texture of the fibers. Wool fibers have microscopic scales that can rub against the skin and cause irritation. This is more likely to occur if the fibers are not spun tightly or if the weave of the blanket is loose. Choosing a wool blanket that has been tightly spun and woven can help reduce the roughness of the fibers and minimize itchiness.

5. Dryness

Dry skin can be a common cause of itchiness, even when using soft fabrics like wool. If you find that your wool blanket is particularly itchy, it could be due to dryness of your own skin. You can try using a natural moisturizer on your skin before using the blanket, or using a humidifier in your bedroom to add moisture to the air.


If you've experienced itchiness with your wool blanket, there are several different factors that could be contributing to the problem. By understanding the main causes of itchiness, you can take steps to reduce discomfort and enjoy the warmth and comfort of your wool blanket. Whether you try using a gentle detergent, choosing a finer wool fiber, or adding more moisture to the air, there are many ways to minimize the itchiness of wool blankets and sleep more comfortably during cold nights.
