The technique of starting from the ends of the hair and working your way up to the roots is recommended because it minimizes breakage and damage. When detangling, the ends of the hair are typically more prone to tangles. By beginning at the ends, you can gently remove knots without pulling sharply on the strands, which can lead to hair breakage. This method allows for the gradual easing out of tangles while maintaining the integrity of the hair shaft.

In contrast, starting from the roots and pulling downward can create more tension on the hair, potentially leading to breakage as you encounter knots. Using a fine-tooth comb exclusively is not advisable for detangling as it can snag the hair, especially if there are knots present. While fingers can be effective for gentle detangling, they may not provide the same level of thoroughness as a proper brush or comb designed for that purpose. Thus, beginning at the ends and moving towards the roots is the most effective and protective method for detangling hair.
