Poison ivy rash is a red, blistering, itchy skin reaction caused by contact with the oily resin of the poison ivy plant. Quickly washing any exposed skin and contaminated clothing, tools, pets, or gear may help reduce the risk of a reaction.

Misconceptions about poison ivy are common - from when you can get it to how you might get it, and the best ways to treat it. Knowing the facts can help you avoid it, or treat it properly if you are exposed to it.

Treatment for hair loss depends on the type of hair loss a person is experiencing. Sudden hair loss often gets better on its own once an underlying condition is treated. Gradual hair thinning caused by aging or genetics may stop or start to reverse with topical medications, oral medications, supplements, laser light treatments, or injections of platelet-rich plasma. And for any of these approaches, the key is starting them as soon as hair loss is detected. Once hair follicles stop working, the only option to restore hair is hair transplant surgery.
