My sister-in-law hails from Morrocco & she told me that argan oil has been used by Berba women for centuries. Its the secret to their gorgeous hair. I couldnt have agreed as I have been using Morroccan oil(which contians precious argan oil) for over a year. My hair has been transformed from a frizzy mess to swathes of silk. I even use it on my 8 year old daughter’s hair. Her hair has become so thick and healthy. I will be repurchasing soon as the bottle which has lasted me a year, is finally finished. sigh:(
