Go for it , you'll love it ....
It's only hair, you can grow it .....
Hmm .... I like my hair short but I have been swithering about regrowing.
Problem is , my hair has taken on SuperWave Properties (and I'm going grey so it's coarser than 10 years ago).
If I get the short back/sides with longer top , the layers go all wild and I get little curls like horns 
So, its gone again. I have it cut every 5-6 weeks.
I'm not sure I want long hair but a collar length would be nice if it did as it was told.
And no clips,hairbands,ribbons or other fancy add ons ....I'm ancient.
Whinge over. As you were .
