i've used it before for a couple of months. i grew one inch in a month in some places of my hair but the accelerated growth did not last long. i believe i went back to my normal growth rate after that. the smell is not pleasant in the least! i mixed essential oils into it and that did nothing. the EOs probably helped my scalp and hair though.
i think cade oil is a lousy carrier oil and for something that was supposedly formulated for humans and cost £19 ($38), i expect better quality ingredients. eventually, i got tried of sub-par results and that ghastly smell so i ended up wasting the last 1/4 of the bottle and mixing my own oils. honestly, i only bought it because i was never going to go the mtg route and boundless tresses has no uk based distributors. in an ideal world, i would have just bought bt (the one with fragrance).
