Skin conditions, hormonal conditions, Folicall Review medications and illness, stress, diet, and genetics play a role in your body baldness. Eczema and psoriasis can also contribute to hair loss on both the scalp and every where else on the body. Cell damage can be irreversible if an individual has 3rd degree burns, so hair will no longer grow in those areas. Scar tissue also inhibits the growth of hair on the body and scalp, so if you have scarring a hair graft is necessary.
Thyroid conditions and hormonal imbalances are the major causes of baldness, so first you must try to target that and cure those problems that are pre-existing.
Treatment will usually halt the loss process, but it will not help your hair grow back. This is where a shampoo or treatment for hair growth can help.
