My hair was down to the middle of my back. It took forever to grow. Cut it for a job, grew it back out, cut it for another job, grew it back out, cut it again.
From my experience, when you are looking for a job and doing interviews, you’ll have better luck with short hair than long hair. However, once you’ve been there a while and have proven your worth, you can grow it out again, if you want.
However, I work in a very conservative industry now though, and I definitely would not have got this job if I had long hair at the interview, or ever really. No guys have long hair at my job, and I work around a lot of people.
I think it really depends on the industry, location, and culture. Like you can have extremely long hair and dress any way you’d like in Silicon Valley, but if you work in corporate at an oil and gas company in Texas, that shyt isn’t gonna fly.
