But now people use different color in hair for different looking. All of them are very harmful to hair because after dyeing, the hair becomes very harsh & its longevity becomes short. To protect it from the bad side effect of dyeing hair, the only way is the oil treatment & as well as Hena treatment. The oil must be the haritaki oil, amla oil or any other ayurvedic oil. 2 to 3 hours after dyeing hair, gently rub the hair oil on the scalp & keep it for half an hour.
