Temporal straight hair
I have a 3B hair type and I straight my hair 2-3 times a year. I let them dry with rollers (no product), after that I put CHI protectant on and I use a straightener in 360-370 F. The thing is that my hair gets a little frizzy and curly with no shine, I would like to know what can I do to make it softer, shinier and straighter when I want it straight. Someone told me about Keratin, but a three-month treatment is way too much. I only use my hair straight for a week every 4 or 6 months. So, any ideas?
