Sunsilk long and healthy growth nourishing conditioner helps for smoothining the hair. I use the conditioner once a week and it keeps my hair straight and silky for a week.we have to just appy it for two minutes and after two minutes we can wash it . the steps are clearly mentioned in the back packaging that makes it easy for us to use it. weshould not use it on daily basis, especially for dry hair as it can make the hair frizzy.
