I have very high ceilingsI replaced the a/c, but the living room and kitchen are still very hot or very cold depending on the seasonI considering adding the spray on insulation to my attic, but it seems to far away and I'm concerned about the rafters being able to vent properlyI have also looked at ceiling tilesI'm considering installing a low ceiling with the a/c ducts moved down and the roll insulation above the ceiling tilesI don't know which one would be the most efficientPlease advise.
any time you want use a heat portection spray
i think this depends on the texture of your hair, how high the heat is on your straightener, and if you're using anything to protect it.but definitely the less you do it the better it is for your hair
id say about 2-3 times a week would be safe
uhm i'd say if you do your hair with a heat tool everyday or every other day it'd be badso i suggest that you try to do natural ways of straightening or curlinglook some up on youtube like: no heat curling, etc.
suggest laying rolled fiberglas in the attic and a ceiling fan down below to help circulate the air in the room below
