I'm no longer transitioning, but when I did decide to both times, I did mentally prepare. I think for some people it just happens but for others there is a thought process. I think just like anything else you "mentally prepare" for, you weigh pros and cons, you look at outcomes, time and money spent.
I prepared by researching tutorials, fotkis, you tube, I read everything about natural hair. I fell in love with the idea that I could actually go natural and unwind years of brainwashing. Besides who told me that I was not beautiful with natural hair?? What voice was I listening too? What lie was I believing? After I got over that and embraced the beauty of natural hair, I was at that point of preparing for it to happen.
I counted the cost- it meant new products, money spent, style options, time spent, etc, etc.
I weighed the pros and cons, pro - healthy chemical free hair, con- cutting 2 1/2 years of progress achieving length.
Just like if you were to decide to transition to being relaxed from natural which I did, I did the same thing. I mentally prepared myself and considered the whole thing. If you were transitioning from singlehhood to couplehood, or motherhood, you would go through the same cycle- read about it, prepare, count the cost, what's the outcome, what it means to you.
Although I am relaxed and content, I have no regrets about transitioning to natural and I still love natural hair.
This is a great thread because most of us on here r strong and knowlegeable about natural hair, but a newbie may not be.
