I wonder the same thing. My hair only grows 1/4 inch of a month at best so that only equals to 3 inches a year...I think breakage can only be controlled or minimized...regardless of what you do you will have some breakage if only a small amount {I've been schooled by Cathy Howse so that's what I believe}...so if I have minimum breakage I will only retain 2 maybe 2/12 inches a year which makes it seems like my hair is the same length because when the two-inches grow in I think wow look at my growth only to see the same amount at the end of the year or the following year. More power to those on the forum who can grow and retain 6-8 inches a year...I've FINALLY stopped kidding myself and realize I can't {I knew this before joining the forum and I got caught up in the hype of at least "trying" to grow my hair} and its not that I'm not taking care of my hair either. I've adopted some of the best healthy hair routine practices and I've used quality products that are not cheap...the products work but I'm tired of trying so many vitamins, growth stimulants like Surge, MTG, moisturizers, protein treatments, etc..only to have the same length or just an inch or two longer...I guess I will just settle for healthy hair...and I know this is not a popular view on this forum {I've been told so many times}...my mother always told me that if you don't have the "hair gene" then your hair will not grow any longer than its predetermined state...{according to some of the "views" I've read everyone can grow bra clasp length hair well it would take me 6 years to do that from where I'm standing and frankly I won't even enjoy it by that time}.
P.S. Does this seeem "vent-ish"...wasn't trying to vent though.
