Bottom Line
The Garnier Olia Ammonia Free Permanent Hair Color is praised for its excellent gray coverage and smooth application, leaving hair feeling soft and manageable. However, its longevity and performance can vary, with some users experiencing diminished gray coverage after three weeks. If you have dry hair, be prepared for potential greasiness. While it offers a rich chocolate brown color, the product may not meet everyone's expectations in terms of volume and lasting results. For those seeking longer-lasting gray coverage or dealing with dry hair, considering alternative products might be worthwhile.
