I'd definitely buy this again

This product has a luxury feel to it and comes in a gorgeous glass bottle and a smart keratese box. I'm already noticing a positive difference in the thickness of my hair with less of it falling out after just 2 weeks use. My hairdresser highly recommended this and it's such a treat for my hair: it smells so great! I'd definitely buy this again.
