I barely reviews, not my thing unfortunately. But wow! I’ve been going natural for a few years while wearing wigs and stopped when I noticed my hair thinning for a year and a half. Stayed away from heat for the majority of the pandemic and saw how fast my hair was growing. Unfortunately, when i would straighten it, it would be a mass of flyaways and look so thin and frail. Tried this out tonight with no expectations; mind you, I didn’t leave any of the mask, shampoo, or conditioner on for more than 7 minutes or so. Applied a small amount of the serum before I blow dried my hair and then a little more before straightening. My hair is shiny, heavy, and healthy looking. I’m in love with that serum, it is GOLD!! Will be telling my friends and sister about this. Thank you!!!!
