Pressing my hair frequently during and right after my transition. My hair was as dry, coarse, shrunken, dense, unmanageable as it is possible to get. I would press my hair several times a week and put oil or moisturizer on dry hair, which just dried my hair out more. I had not as yet found LHCF, and once I did in 2005, I stopped pressing my hair altogether and have only flat-ironed about five times since then. I was trying to tame my hair with heat, but what really/actually tamed my hair (got my hair to behave) was moisture, moisture, moisture and I haven't looked back. I started co-washing nearly every night and used a bit of oil like almond, avocado, olive, etc. on wet hair and then sealed with shea butter. The first time I did this, I woke up with moisturized, non-greasy hair and it was wonderful. That is where I turned the corner because my transition and right after was hellish.
Now, of course, I have evolved beyond that to using aloe vera mixed with a creamy leave-in (my current favorite is Surya Henna's volume reducer with tucuma and cupuaca butters) after co-washing or rinsing and sealing with whatever butter I have on hand. My current butter mixture is ghee, wheat germ butter, avocado, castor, camellia and monoi oils. The more moisturized my hair is, the looser the curl and wave pattern and it is pretty much non-existent at this point. People are constantly saying to me now that I have "good" hair and I think, "No one was saying this three years ago, so how did I suddenly get good hair?"
(For the record, I do not believe in good/bad hair. I believe in properly cared for hair and improperly cared for hair.)
