3. Breakage and Split Ends

Frequent coloring, especially bleaching, increases the risk of split ends and brittle hair. Over time, this makes hair look thinner and less manageable.

For some, coloring irritates the scalp, leading to itchiness or sensitivity. While not everyone experiences this, it adds to the discussion around does hair color damage hair in the long run.
