I have eczema what should i use & what should i stay away from & also i always take hot showers should i take cool showers instead to relieve itching?

Yes: Long, hot showers are the worst things you can do when you have eczema. Luke woram, short showers with moisturizing soap would be better. Then follow with a good moisturizing lotion all over the body will keep you more comfortable. Instead of scratching when it itches, use more lotion.

Tepid water showers: Definitely you should moisturize with a cream or ointment multiple times a day. You should use OTC steroid cream as needed for tough to treat spots. Hot showers will irritate the skin, try taking tepid water showers and moisturize immediately after to lock in the moisture. Recent studies show that wet wraps are very helpful but might be impractical for person with very busy lifestyle

Yes: and make the showers short. Water is the enemy of eczema. Quick in and out showers with lukewarm water, a non-irritating soap ( I prefer dove sensitive skin , as it is cheap, easy to obtain and works well) and plenty of lubrication with aquaphor or lubriderm. I hope this helps! :)
