Hi geeks, is 5rv in matrix quite vibrant ? My clients got an inch of roots base 5 and 6.86 in igora on the rest, would I get abit of root glow with 5rv? Just asking as ive not been on my introductory course as it got cancelled and used a 5n last week on a lady and it's more like a 4n so just worried bout putting any more matrix on anyone. Xxx
