My hair is naturally dark blonde, but has for the last 10 years been bleached to one extent or another and that has made my hair incredibly dry, especially at the ends. I use lots of heat to style my hair including a hairdryer, hair wand and straightening irons. I use INTELLIGENCE after I wash my hair. I apply it only to the ends of my hair as they are in need of a super moisturising product. I have used other overnight treatments but I prefer the smell, texture and luxury that INTELLIGENCE gives me. It definitely mends my split ends and makes my hair softer and shinier with no build up. INTELLIGENCE is quick to use, smells amazing and more importantly deeply moisturises my damaged ends. I would recommend this to anyone who has bleached hair or has had the bottom of their hair lightened as an Ombre treatment.
