The treatment comes in a box with ten little 10ml bottles, which is enough for ten separate treatments - even on my long locks! Not having to use it all that often also means that it lasts absolutely ages. I've had the product for a while now and I've still got some bottles left. I use a capsule about once every two months or so.
You can either use the oil hot or cold. I always opt for heating it up a little first as it really gives that deep treatment my hair needs. Otherwise it's a simple case of rinsing your hair, popping it on, massaging it in, leave to soak up and then rinse out!
