Review: Si es un bonito color y es bastante bueno
Review: Garnier Hair Color Olia is a popular choice for those looking for an ammonia-free hair dye with a focus on nourishing and vibrant results. Here’s a comprehensive review based on its key features and performance: Pros: Ammonia-Free Formula: One of the standout features is that Olia is free from ammonia. This can make the application process more pleasant and less harsh on the hair and scalp. It also helps to reduce the strong chemical smell often associated with hair dyes. Oil-Rich Formula: The dye is infused with natural oils (like flower oils), which help to nourish and condition the hair during the coloring process. This can leave hair feeling softer and looking shinier compared to some other dyes that can be drying. Rich, Long-Lasting Color: Many users report that the color results are vibrant and long-lasting. The dye is designed to penetrate deeply into the hair fiber, which helps the color to stay true and not fade quickly. Pleasant Scent: Compared to traditional hair dyes, the scent of Olia is generally considered to be more pleasant, likely due to the absence of ammonia. Wide Range of Shades: Garnier Olia offers a broad spectrum of shades, from natural to vibrant colors, making it easy to find a hue that suits your preferences. Good Coverage: It provides excellent coverage for gray hair, which is a significant benefit for those looking to cover up grays. Cons: Application: Some users find the application process a bit tricky. The oil-rich formula can be thicker and might not spread as easily as other dyes. This can sometimes make it harder to ensure even application. Development Time: The processing time might be longer compared to some other dyes, which could be a consideration if you’re looking for a quick coloring solution. Color Variability: As with any hair dye, results can vary depending on your starting hair color and type. It’s a good idea to do a strand test before applying the dye to your entire head to ensure you get the desired shade. Price: Garnier Olia can be a bit pricier compared to some drugstore hair dyes. However, the benefits of an ammonia-free formula and nourishing oils might justify the cost for many users. Overall: Garnier Hair Color Olia is a strong contender in the ammonia-free hair dye market. It offers vibrant, long-lasting color while being gentler on the hair thanks to its oil-rich formula. It’s a great choice for those looking to avoid ammonia and who appreciate added conditioning benefits. While the application might require a bit more effort and the price is slightly higher, the results often justify these considerations.

## Questions & Answers

**Q: Is Olia less effective than a hair color with ammonia?**
A: No, even though Olia does not contain ammonia it's just as effective as a classic hair color with ammonia

**Q: How effective is Olia on grey hair?**
A: Olia is a permanent hair color and delivers on up to 100% grey coverage for up to 6 weeks.

**Q: Many brands have oils nowadays… How is Olia different?**

A: You may need to vary the development time throughout your hair. Follow the instruction leaflet for timing and application techniques. Use our step by tep tool or watch the how-to video.

**Q: How much product should I use to get full hair coloration?**
A: Like all hair coloring, it depends on your hair length and thickness. For medium to long hair use 2 boxes. For long hair or hair that is very thick, you may need to use more than 2 boxes.
