hello, i tried only one conditioner bar, but in theory you should be able to rub it in wet hands for a while to get them covered in the conditioner and then use that on the hair as you would use a normal conditioner... but i couldn't get enough moisture that way so i also kind of stroked my hair with the bar as you would with a brush. i also heard some CGM people cut off a part and dissolve it it water by heating it and make it into liquid conditioner but no experience with that. it didn't really work out for me either way though, either it wasn't moisturising enough or i had to use a big part of it for one wash so it turned out kind of wasteful in the end.
