I have been using castor oil for a long time for my hair, and I wonât say it was not effective, but it didnât quite made my hair sleek as I wanted. I had done hair extensions a few months ago, and my hair became frizzy and thin in some time only. I have heard a lot about Agadir hair oil in advertisements, but I want to learn from someone out there who has ever used it. Can you guys please tell me, if it is equally effective on chemically treated hair as mine? Moreover, do you think, it is as good as castor oil for hair as mine? Please advice appropriately. Thanks.
