Itching on your scalp is a direct symptom of an inflammatory reaction of the skin, and while the severity or duration of an itchy scalp is determined by its underlying cause, it may be possible to find relief through the use of aloe vera. While aloe vera has been used for centuries as a topical treatment for various skin ailments, if your scalp is persistent and is not relieved through natural remedies, immediately seek medical attention as you may require prescription-strength medication for relief.
Active Constituents
Aloe vera contains a total of 15 active constituents. The University of Maryland Medical Center states some of the most active compounds in aloe include polysaccharides and glycoproteins. When applied topically, polysaccharides are known to stimulate skin cell repair and growth, and glycoproteins are used by your body to expedite the healing process while simultaneously reducing inflammation. Even though aloe is comprised of 99 percent water, these active constituents have proven to have medicinal benefits.
Evidence
While the effectiveness of aloe on an itchy scalp may be determined by the underlying cause of the itching sensation, preliminary evidence suggests aloe vera may help relieve certain forms of skin itchiness. If the itching is caused by excess dryness in your scalp, aloe vera may help provide relief as Purdue University reports aloe gel contains moisturizing properties, which may relieve excessive dryness and itching. An itchy scalp caused by seborrheic dermatitis may benefit from aloe as preliminary evidence outlined by the Mayo Clinic shows aloe can potentially reduce seborrheic dermatitis symptoms. A study published in the February 2003 issue of the “American Journal of Infection Control” found the gradual application of aloe vera gel on skin effectively improved skin integrity and reduced dry skin as well as irritant contact dermatitis among women with occupational dry skin. While this study was not performed on the scalp, its evidence does suggest topical application can help protect skin from irritation.
Application Methods
While there are no official application instructions for dry scalp, the University of Maryland Medical Center suggests applying a liberal amount of aloe vera gel onto clean skin. Because aloe gel can make your hair look wet, apply at night before going to bed. Wash your hair, and while your scalp is still wet, massage a liberal amount of aloe gel onto the affected areas. Allow the gel to rest overnight, and rinse in the morning.
Warnings
Although aloe vera is generally considered safe for healthy adults, talk with your doctor before applying aloe gel, especially if you have a medical condition such as eczema, psoriasis or shingles. The most common side effect of aloe topical application is a mild skin rash caused by an allergic reaction. If you develop a rash, immediately discontinue use.
