I have been using treasured locks argon oil for past couple of months now, but I havenât seen my hair growing as long, as I thought, however, they do appear soft unlike earlier. I have learnt about some multi-vitamins from treasured locks, and I want to know from somebody who has actually used it, that whether it would help me grow my hair really long, at least up to my waist. In addition, is it advisable to take multi-vitamins when already using argon oil! Would it really make any difference, if I discontinue the oil, and start with treasured locks multi-vitamins? I would be grateful for a suitable reply from you guys! Thanks.
