  • Really works!
Style: 5.1 oz, New Look
This is the only conditioner I use. After a shower, there is virtually no hair in the drain, and no tangles when brushing. If I do use another product, the drain is clogged with hair, and it takes a long time to detangle. The downside is this is very expensive and smells weird, but it really does work! ... show more

  • Works great!
Style: 8.5 oz, New Look
Got a perm that over processed my hair. A friend recommended this product and it has transformer my hair from feeling like straw back to soft and shiny!

  • Literally Gold for Your Hair!
Style: 1.7 oz, New Look
The product I have been looking for my entire life is finally here! I have extremely dry hair naturally, and it tangles instantly, which is why I’m losing it so fast. I use heat protectants, I rarely use curling irons and never flat irons, and I usually let my hair air dry. Nothing I’ve tried has given me detangled, easy to brush hair. But after using this product one time, I was able to brush my wet hair with zero knots or tangles. It stayed like that while blow drying and even still hours later. I can finally run my fingers through my hair without losing hair in the process. It looks so shiny! I’m so relieved to have found this product! ... show more

  • Love love love this product
Style: 5.1 oz, New Look
Color treated hair every 6weeks so I have to stay on top of hair regimen for damage. This product makes my hair so soft even after the first use. Smells great too. It is kinda pricey but worth it

  • This brought my dry, brittle, fine hair back to life
Style: 5.1 oz, New Look
I tried so many different products including Olaplex, which did very little for my hair. This ended up being the holy grail. My hair is fine, but I have A LOT of it, and it was suffering from intense dryness for some reason (probably a mix of breastfeeding/hard water/using a cotton towel to dry). For reference my hair goes down to my butt so it is very long. It was so brittle that I was starting to get very bad split ends and loosing hair. I remember when my hair stylist said many years ago to just leave this product in my hair all day and let the sun soak it in, or lightly blow dry it, so that's what I did and wow. So glad I remembered that advice! ... show more
