What are your thoughts on a blow out(straitening hair)?

My sister got a blowout and out of experience it looks better on thicker hair, because on thin hair it can look a little "volumeless" if that makes sense. As for the hair color, it doesn't matter at all as a blowout looks pretty much nice on everyone, actually your face shape and haircut are much more important factors to consider when getting a blow out. If you want to dye your hair, it would be best to first determine your skin color undertone, as this is what can help you decide if auburn is a right color for your skin tone. Lastly, if you do decide to dye your hair it would be best to wait a bit to do the blow out as dying your hair really damages it and if you add the blow out to that, your hair might be really dry and damaged.

Brazillian blowout? The one that lasts a long time? I got one and it looked good, but damaged my hair when it grew out. A normal blowout only lasts a day or two.
