How do you classify sodium laureth sulfate. I am allergic to sulfa and I need to know if my shampoo and body wash are causing me problems. One of my symptoms to food allergies is that I have no energy. Lately I have had no energy. Could I be absorbing it

It . It is really unlikely that yopu would absorb enought to cause any issues. Your symptoms should be addressed by your doctor.
Yes. If you are allergic to sulfa there is a small cross reactivity to sulfate. The small amount of sulfate in your shampoo and body wash should not cause you a huge problem. If you are highly allergic to sulfa then you should be getting a local reaction like itching, rash from the use of the shampoo and body wash.
