I see alot of ladies here go for many months w/o trimming their hair while still maintiaing thick, healthy ends. HOW DO YOU DO IT???? Without fail, at the 4 wks post, my ends act crazy. The last 1/2 inch of my hair bends up which I've been told means that the bend is a weak point where my hair will break. I can't go through 4 wks without seeing those little 1/2 inch ends. I airdry my hair and the only heat i use if for my DC or steam from my Carusso's, I also moisturize my ends w/ either jojoba or almond oil. Can someone tell me what I'm doing wrong? Please help.
