After trying a different tea tree shampoo, I decided to look around and try some others as well and find the best one for me. I used this shampoo at the same time that I used the conditioner so I was able to fully see the results of the duo together. Overall, I was really happy with my purchase after using the Giovanni Tea Tree Triple Treat Invigorating Shampoo. It smelled pretty good and did a really good job at cleaning my hair. It removed a lot of the build up from my styling products that I had used during the day without over drying my hair. The smell lingered for a bit, but it ended up being really subtle by the time my hair dried. This shampoo also worked really well with my colored hair and didn't cause any color fading. While it didn't prevent split ends from forming, I did notice that there were less overall over the course of using this shampoo. It worked well at preventing frizz too. This shampoo was affordable. I wasn't a huge fan of the bottle's shape, it comes in a rectangle bottle so grasping it in the shower is kind of annoying, and it slipped out of my hands a few times during use. Effectiveness Like I said, it was really good at cleaning my hair. It made a nice lather and my hair felt really clean after I used it.
