Works on dry dry dry frazzled bleached hair! I was really skeptical about this product- I don’t use sulfates or parabens lol and I steer away from any frying products that will worsen the condition of my hair because it’s wavy dry and bleached to a level ten platinum- I LOVE my blonde and will never sacrifice the color from length or health but!!! I bought this with no reviews like mine anywhere online and I am here to tell you- it works. It’s safe. Be careful and mindful of your scalp of course and of the porosity of your hair... I followed instruction and avoided an inch off my scalp because I have some roots growing in and I heard keratin plugs pores so, then I waited thirty mins because my hair is again veryyyy porous. I blow dried half way until my hair was like moist but dry and obviously not straight enough for me so I went in with my straightener at 320 degrees. I have POROUS hair so again I was weary. I did experience some fallout throughout this entire process! I had hair break off but it’s just normal shedding. Well after I finished straightening my hair I saw it was smooth, pin straight and shiny ! My hair really was frazzled and frizzy beforehand it made it hard to straighten my hair in the first place. When it rains my hair poofs up even after a professional straightening lol here’s a pic after the rain - and it’s natural state- and how my hair looks a free the treatment and straightening. Hopefully in three days my hair dries this pin straight !!
