I am so sorry you went through that, it is so disheartening when that happens!I am dancing...
to the OP: I have a long way to go...my hair is about 2-3 inches in length all 'round...after the haircut from hell. I need to do the hair growing dance 24/7!!!!
I also had the haircut from hell in 2006...because of the way it was cut, I have to continue to cut the ends until all the damaged parts finish growing. I also have about 4 to 6 inches of hair, but when it is dry, of course it seems shorter.
What type of bad haircut did you get? The butcher used a razor and thinning shears on my hair. I guess I had too much hair for liking.
The "stylist", I use that term loosely, took thinning shears, and just kind of picked up a chunk of hair and chopped away, all the way around my head. Then the razor came out and it was razored around the sides, and in the front, I look like I have a half mullet...ugh! But I see the new growth coming in and that looks so much thicker and healthier. Although, finding out through trial and much error, I am protein sensitive, so now it limits what I can use on my hair, so I am careful.
Still dancing here, and doin it in my sleep too!!!
