I used to get a texturizer (Wave Nouveau in the green bottle, I think. This was in 1999/the early 2000's). After a couple of years of texturizers, I started getting actual relaxers to straighten my hair. They never straightened my hair...just made it really fluffy and undefined. I used to get weekly blow-outs.

And then I decided to stop with the relaxers because my hair was starting to break. I switched to just heat straightening. I was getting blow-outs once a week and "touching up" at home every other day. My hair was COMPLETELY wrecked.
Hair type: Mostly 3C, medium porosity to high porosity depending on the day, dense, fluffy, dry, tangly!
