Is lemon good for hair?
Lemon is usually used in hair oils and shampoos. But directly applying it may irritate the scalp skin. Do a patch test before applying it.
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.
