I have tried every product on the market for detangling my daughter's hair. She has thick knotty hair. I always thought the more expensive the product, must mean it's more effective. Not true. I saw this and didn't have high hopes, but wow was I surprised. What's good is that after continued use, I found that even without the product, her knots were not as bad. I have gone on to purchase most of the range after using this.
