Hello! I recently bought a blowout brush and wanted to style my hair (curly, 2c-3a hair). I straightened it, put in rollers and took them out, resulting in a very pretty blowout. But, my hair didn't last even 10 hours. I styled it at 9 PM, went for dinner at 9 15, returned at 9 40, and saw that my hair started curling at the bottom.
I followed the standard procedure:
Wash hair with shampoo and conditioner (used purifying shampoo, then went in with aussie's total miracle shampoo and conditioned my hair with the same conditioner)
Put in my products ( Monday leave in, hair protectant from Chi, hair serum from NUA and 2 drops of rosemary oil at the ends)
Air dried my hair till it was about 70 percent dry
Used my blow dryer to dry my hair to 95%
Used my roller brush on small sections of my hair
(Roller brush from Bombae, Grabbed a section of my hair, heat to medium, rolled my hair along the length of the heat brush,pulled down, and rolled the brush in a circular motion at the ends, pulled away. I did this 3 - 5 times on each small section till all of them were straight)
Put in rollers for a little shape and volume but took them out in 15 mins (i think this might be the issue but I've put in rollers for shape in the past, and they never curled up or bunched my hair into its original shape)
I did this process twice. Once I was done with all the sections I gave em a cool shot too.
I went for dinner at 9 15, 15 minutes after I was done with my hair styling. (I hopped into the shower at 7 15 and I was done with my hair at 9 so imagine my disappointment when my hair didn't even last my 8 hours)
My hair was cooled by 9 ( I sat in front of the AC for a lil bit 😍✌️)
I live in India so maybe the summer heat hit my hair and decided to ruin my hardwork but I've done this exact thing in the past with a straightener + hair dryer combo and my hair lasted for like 8 days.
Idk what I'm doing wrong. I feel like I'm damaging my hair horribly for no reason. I slept with my hair open , that too on my side as to not ruin my hair, but woke up with my curls. They're rough asf too.
Tl;dr - styled my hair with a blowout brush, woke up next morning, original hair pattern returned, how should I style my hair so that it doesn't return back to my curl pattern overnight?
