I'm not sure whether it helps my hair to grow longer (long term), as I've only used it for a few days. It applies well, doesn't leave my hair at all greasy (I use this on my hair when it's wet and then dry it in), smells really nice, and leaves my hair lovely and soft. Since using this, I've had compliments from people saying how my hair looks in lovely condition. It's a worthwhile investment for your haircare routine. Alongside this, I use a heat defence spray, and they work great together. Review: Amazing product - I’ve been using this after every wash (1-2 times per week) for probably getting on for 3 months now. One bottle has lasted me that time aswell. I have thick long hair and this stuff leaves my hair so shiny and smooth. I also feel that it has helped prevent breakage as it feels longer and stronger definitely! Would 100% recommend. I use along side the bond repair shampoo and conditioner ## Features - STRENGTHEN HAIR AT THE ROOT: this hair fortifying treatment helps provide strength & thickness to each individual hair strand.
