Epsom salt, formally known as magnesium sulfate, is a naturally occurring mineral compound composed of magnesium, sulfur, and oxygen. Scalp psoriasis is a chronic autoimmune condition that accelerates the life cycle of skin cells, causing them to build up rapidly on the scalp. This results in thick, red, itchy plaques covered in silvery-white scales. This article evaluates the potential efficacy and proper methods for using Epsom salt as a complementary approach to manage these symptoms.
The Science Behind Epsom Salt for Skin Relief
Magnesium sulfate offers relief through its combined physical and chemical properties when dissolved in water. The magnesium component is thought to possess anti-inflammatory qualities, which may help calm the redness and swelling associated with psoriasis plaques. Applying magnesium to the skin is anecdotally used to soothe irritation and reduce the sensation of itching (antipruritic effect) often experienced by those with scalp psoriasis.
The salt crystals act as a mild scale softener, assisting in the gentle removal of hardened, excess skin cells. This mechanical action helps loosen the thick scales and flakes, making the scalp smoother. While these soothing and exfoliating effects are commonly reported, scientific data confirming the medicinal benefits or transdermal absorption of magnesium for psoriasis is limited. Therefore, Epsom salt is considered a supportive measure rather than a primary treatment for the underlying autoimmune issue.
Applying Epsom Salt Treatments to the Scalp
Targeted application is necessary for scalp plaques because hair makes traditional soaks difficult, requiring more concentrated methods. One effective approach is creating a paste to address localized, thick plaques. Mix equal parts Epsom salt and warm water to form a thick consistency, ensuring the salt is only partially dissolved.
Carefully apply this paste directly onto the affected areas of the scalp, using fingertips to press the mixture onto the plaque without vigorous rubbing. Allow the salt to sit and soften the scales for up to 15 minutes. Rinse thoroughly with lukewarm water afterward.
Alternatively, a diluted rinse can be used as a finishing treatment after shampooing to soothe the entire scalp. Dissolve one cup of Epsom salt in a large pitcher of warm water until fully incorporated. After washing, slowly pour this solution over the scalp, ensuring the affected areas are saturated.
Allow the rinse to sit on the scalp for a few minutes before performing a final rinse with clean water. Because salt can be drying, adding a small amount of a carrier oil, such as olive or coconut oil, to the paste mixture may help prevent moisture loss. It is imperative to rinse all salt residue completely to avoid further irritation.
Potential Side Effects and Medical Context
While generally safe for topical use, Epsom salt can cause excessive dryness and irritation, particularly on the sensitive skin of the scalp. Using too high a concentration or applying treatments too frequently can worsen existing symptoms or trigger a flare-up. Exfoliating scrubs must be used with caution, as aggressive scrubbing can irritate the skin.
Epsom salt should never be applied to areas with open wounds, cracks in the skin, or severe inflammation, as this can lead to burning and potential infection. Epsom salt is a complementary home remedy and is not a substitute for medical treatment prescribed by a dermatologist. Psoriasis requires professional long-term management.
Consult a healthcare provider before beginning any new remedy, including Epsom salt treatments, to ensure it will not interfere with prescribed topical medications. If symptoms worsen, if signs of infection appear, or if there is no improvement after a few weeks, immediate medical consultation is necessary. A patch test on a small area of skin is also recommended before full application to gauge individual sensitivity.
