What you can do when you have itchy skin depends greatly on where that skin is located. You may think that skin is skin so what works in one area will work anywhere, but that is not always the case. If you have dry skin, dry scalp, and itchy feet, you may have to have three different remedies for these problems. If you have dry skin in general, you may find that one good lotion takes care of all of your problems, but that is rarely going to be the case. Think about your itch and you will know how to take care of it, and if not, someone online certainly will.
Itchy skin on the top of your head is called dandruff, but you may not see flakes even if you have problems in this area. You may just have the itch. You can not put lotion in your hair, obviously, unless you like the really greasy, stringy, look. Even then, lotion that works well on dry arms or legs is not going to do anything for the itchy skin on the top of your head. Get a good dandruff shampoo and use as often as you need. Some need it every day and some need it only once a week.
If you have itchy skin on your feet, it could be that they are dry, but it could also be that you have athletes foot itch. You do not have to be athletic to get this, but you do have to be exposed to it to get it on your feet in some cases. What you want to do about it depends on the severity of the itchy skin on your feet. If you have problems between your toes and your skin seems to be cracking and feels like it is burning, you want a remedy just for athletes feet. Some are over the counter and some are prescription. When caught early, you can use something from the drug store. If your feet are in bad shape, you should see a doctor as soon as possible.
Itchy skin on your torso and extremities may just be dry skin. There are many great lotions out there that can take care of this for you. Put your lotion on right after you shower before you dry off with a towel to make sure that lotion pulls that moisture into your skin. It may seem like you are just smearing it around, but this is the best way to get the most moisture into your itchy skin. If you find your skin is smoother but still irritated, look for lotions with minimal perfumes and additives. You may be sensitive to those things and there are several good lotions for that problem too.
When you have tried many different lotions for your itchy skin and nothing seems to help, and you notice that you have some red and scaly skin patches, you may have a more serious skin condition that needs medical attention. It won’t hurt you too much, but you will suffer with the itch and irritation if you do not get help. At times, sun exposure can help with this, along with some prescription lotions and medications. Not all itchy skin is the same, and what works for someone else may not work for you. Identify the problem and try different products until you find the one that works the best for you.
