Yes and No.
I'll admit that many men around here are into long straight/wavy hair.
But I get hit on most when I am confident. I have a friend who wear a TWA, and has been wearing one for years, and she gets hit on just as much as the next girl. That's because she carries herself with confidence.
If long hair is what you are seeking, you surely will present yourself in a different manner as your hair gets longer and healthier. You'll finally feel "on-point", and we all know how great we feel when we are looking GOOD!
