From the start of our transition, T has opted to wear her hair flat ironed straight half of the time as her styling option.
natural state (with the help of perm rod rollers), occasionally flat ironing just to see my growth progress. It was pretty encouraging to see how long my hair got during transition!

Judging from the growth that she's already achieved and retained, I would say that it is very possible to use heat in a safe and responsible way, and grow your hair as long as you'd like. I want to put out there that
the condition of your hair should be healthy before experimenting with heat.
So back to T and her hair growth. The condition of her hair appears to be healthy, lustrous, and is retaining length rapidly. Her ends are trimmed as needed.
We plan to track the following:
1) Length
2) Condition of Hair Ends
3) Hair thickness (as it relates to each individual--mine is thicker than hers naturally)
4) Overall hair health (especially while curly)
Our review will take place in March (towards the end). We will report in a post to advise of our findings. I think it will be really interesting, because the outcome could prove to be very helpful to anyone not wanting to use chemicals on their scalp anymore, but still loving straight hair.

We'd love to hear from transitioners and naturals about their experience with heat and hair length retention. Meanwhile, we'll follow up on this post at the end of March with our results.
