Can hair grow back after thinning?
Hair may not regrow totally but thinning can be managed with medical intervention but it should be treated in early stages to have better results
Hair always grow according to its growth cycle but the total transition to old normal hair depends on the cause of hair loss. If hair loss is secondary to genetics then re-growth is doubtful unless a medical intervention is done. Hair loss secondary to infection, nutritional deficiency and damage may regrow once the cause is taken care.
