If you've got scalp psoriasis, you've probably tried every shampoo recommended by your doctor. Maybe you've even attempted some "home remedies" that aren't classified as shampoo. How can you tell if something will work for you before you take the plunge? The truth is, you can't. But you can learn more about which non-medicated shampoos might be more likely than others to help, not hurt.
What makes a shampoo just that?
Most shampoos on the market have similar main ingredients. Number one is usually water. The second ingredient is usually a surfactant—a cleansing agent that attracts water and oil in a process that pulls dirt and deposits away from the hair. Then, other ingredients such as oils, moisturizers, proteins, and foam-enhancers—along with many potentially irritating chemicals—are added. These make each product unique.
Is pH a factor?
The pH scale is a measure for the acidity or alkalinity in substances. Solutions containing alkalines (pH 7-14) tend to soften and swell hair, while acidic solutions (pH 0-7) tend to contract and harden hair.
Healthy skin and hair have a pH factor of around 5 (which is mildly acidic). Over-the-counter shampoos generally have a pH of around 8 (more alkaline)—and conditioners have a pH of around 4 (more acidic). So using a shampoo and conditioner together is a good way to neutralize the pH level and restore the natural balance of hair and scalp.
Let it soak in.
For people with psoriasis, the key is to loosen and remove scales, while providing as much moisture as possible. Your daily routine of blow-dryers and styling products can contribute to drying and can worsen psoriasis.
Some of the more popular shampoo options for treating psoriasis include coal tar or salicylic acid, both of which are known for their exfoliating properties. (Be aware that products containing tar or anthralin may stain light-colored hair.) To avoid over-drying the scalp and hair, some dermatologists recommend that you rotate psoriasis-treatment products with non-medicated shampoo and conditioner. And, be sure to condition every time you wash. That can help replace the moisture needed to keep your scalp balanced and healthy.
Non-prescription shampoos that contain salicylic acid include:
- Neutrogena® T/Sal Therapeutic Shampoo
- P&S® Shampoo
- Sebulex® Shampoo
Of course, make sure you talk with your doctor before changing your hair care regimen.
