My daughter has atopic dermatitis, and using products that don't suit her skin can cause itching and inflammation.
Also, if the shampoo mixed with water comes into contact with the affected area when rinsing it off, it may cause pain and make you cry.
This shampoo was recommended to me by my dermatologist, so I immediately bought it and tried it out.
Although it does not use soap, it lathers up well and is easy to use.
Even if the shampoo foam comes in contact with the affected area, it won't cause any stains, so it's safe for children as well.
Also, it doesn't make my atopic dermatitis worse, so I completely switched from the shampoo I was using to this one.
