I’m gunna go ahead and disagree with the regular trims-I know it’s contrary! But, in my personal experience, I went through several years of trying to grow my hair really long but every time I went into the stylist she would take several inches of “split ends” off. If you do the math-your hair grows about one half to two thirds of an inch a month-you can figure out that my hair ALWAYS stayed the same length. It was incredibly annoying. I finally just stopped having it cut when i went in to have it dyed and I have had SO many people comment on the length of my hair and I love it! I know that it is not as healthy as it could be, but it is really never going to be that healthy because I dye it and like to do fun things as far as styling, etc. So, I just use Bumble and Bumble De-Frizz and it looks shiny and beautiful. So, maybe that is just covering up the spit ends, but who really cares?! Good luck!
