I don't think sunsilk as good in this product as its in other varieties like its shampoo.
This oil seems to be very sticky and it may give a shineness to your hairs but its shineness doesn't look to be quite natural , as the same thing is available with other brands at lower cost.
Styling of hairs mostly depends upon the person who is actually giving his or her hand for styling, so ease of styling is not much to its part.
Its not cost effective and its quite unreasonably costly, may be they are encashing their brand good will in this market too.
Its quality seems to be dominated by chemicals mainly as fragrance is too strong and the person standing nearby you , will surely get an idea that you have an oil on your hairs.
You can have many other brands in same range as a worthy choice.
