Stretching a Wash & Go with a flat iron

Here is a quick iPhone vid on how I have been stretching my hair with a flat iron instead of a blow dryer.I've been doing this for a month, using the wetline gel to set my wash & go, and have noticed no damage. I keep the iron on a low 300 (lowest mine goes) and I use Nubian Heritage honey & blackseed leave in is my heat protectant. I get a week out of this!!
