Expensive but worth it
A very concentrated product, only need a tiny amount to add a really healthy finish to hair

Must have!
This is an absolute repeat buy for me. I’ve noticed that my split ends look more repaired. My hair is shinier overall and looks healthier. I also noticed my hair grew longer than it has in years!
