I bought this because I read somewhere that it helps hair loss. I have used it for some months and it definitely doesn't work. When I tried mixing this with a hair oil I know does help hair loss, the other oil lost its effect! The only thing this does is leave me with a smell I don't like and a residue I can't manage to wash out because the oil is so thick. This was an absolute waste of time and money for me.
Of course, I didn't want to just throw the bottle, so I used this as a hair mask. When I took off my turbie twist and plastic foil, my hair felt nasty - oily and stiff at the same time (I believe olive oil would have given the same feeling though)Because this is VERY oily, I added baking soda to my shampoo, then used vinegar as a first conditioner. I'm not that natural when it comes to many other things, but baking powder followed with vinegar is great when I need to wash something reeeeally sticky out of my hair. Still, my hair felt very stiff and glued together - at this point I was a little afraid I wouldn't manage to wash this out of my hair. I figured out I should just calm down and put my regular conditioner all over my hair. Then something almost magical: my hair suddenly relaxed. After this I added a little bit of It's a 10 Leave-in conditioner, and my hair felt very silky. Trying the oil like this was definitely a good idea for the event I was going to, BUT, it took about 1/2 of the bottle of this for my normal thickness, waist-long hair... and this oil isn't very cheap. As I said, I haven't tried olive oil for my hair, neither have I tried coconut oil for it, but if they do as well as this, the Weleda hair oil is a huge waste of money as a hair mask. Therefore I gave it only one more star.
