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.

Toasted skin syndrome is a rash that develops in a fishnet-like pattern from direct, chronic, low-level exposure to heat sources such as laptops, electric blankets, heating pads, and heated car seats. The heat dilates superficial blood vessels under the skin, causing the rash.

Itchiness of the breasts or nipples isn't common, but can signal conditions both harmless and serious. Minor reasons for itchiness across the bra area include eczema, psoriasis, exposure to soaps or detergents, trapped moisture, and pregnancy and breastfeeding.

Any skin changes on the breast that don't improve over weeks should be evaluated by a doctor.
