Review: #1 Bestseller for a reason - Expensive and worth the money. There’s a reason it’s number 1 in this category.
Review: Good product - Good product, it does NOT repair heat damaged hair. It diffinately restored/enhanced my severely damaged hair. After cutting away the heat damaged hair and following the instructions I got a great result. My hair elasticity and tight coils returned; with major shrinkage 😐. Will buy again!
