How to Use: Apply to damp hair before shampooing and conditioning. Generously coat from roots to ends, leave for up to 10 minutes, then rinse and follow with shampoo and conditioner. Use once a week or two to three times for damaged hair. 

Olaplex No.3 Hair Perfector Celeb Reviews

Kyle Richards said, "I highlighted my hair and it got really damaged. People started telling me to use Olaplex. I had never heard of that because I never had damaged hair, to be honest. This is everybody's best kept secret. It's amazing. I use it all the time. This is such an incredible product for repairing damaged hair."

Brynn Whitfield raved, "It helps with damage. I use a lot of heat, so it helps reverse a lot of that damage. I know it's small. Great things can come in small packages." 

Margaret Josephs gushed, "I bleach the crap out of this hair. When you're always doing stuff to your hair, there are a lot of different products that people use. I like to use Olaplex because my hair dresser told me it was great. I test out everything. I buy every product under the sun. Olaplex is amazing. It doesn't weigh my hair down, and I have fine hair. This great." 

Paige DeSorbo said, "My hair can get really dry, so I use the Olaplex hair mask once a week. I shampoo my hair first though actually before I use it to get rid of the product build-up I may have. It also really affects hair better if it's freshly clean."

Olivia Holt told E!, "We do 8 shows a week so I can't possibly imagine the condition my hair would be in if I was putting heat on it like that for every show. I do love an Olaplex hair mask though a few times a week."

Kathryn Hahn shared, "I love all of their products because my hair is so dry – this has helped bring life back to it."

Ally Brooke explained, "I just went blonde and thanks to Olaplex my hair is so strong and healthy! It is a product that is a life saver to your hair. I recommend this for everyone!"

Supergoop! Unseen Sunscreen Celeb Reviews

Shay Mitchell told E!, "I never leave the house without sunscreen so have literally tried them all but lately I have been into the Supergoop Unseen Sunscreen." 

Brynn Whitfield said, "I tried on a bunch of different sunscreens and this was my favorite because this was the only one that was so thin it didn't feel like a sunscreen. I don't want to put something on and have it feel icky, white, or pastey." 

Dr. Tiffany Moon shared, "Anyone who saw me on Real Housewives of Dallas knows that I am serious about my sun protection. I slather this stuff on myself and my kids anytime we go outside! Always wearing SPF is the best skincare hack!"

Amanda Stanton said, "Sunscreen is huge. I love the SuperGoop sunscreen and my kids do too. It's oil free and goes on smooth. They have a spray too!" 

Dylan Barbour advised, "Newsflash: it's extremely hot and sunny in the desert. Put on sunscreen and protect your skin."

Refresh and revitalize your hair with this dry shampoo that instantly adds volume and helps create the appearance of thicker, fuller strands.

Shoppers Say: "Perfect for long, thin hair. I have long, thin hair and I use dry shampoo a lot. I have tried Batiste, Redken, Amika, Living Proof - you name it. This is going to be my go to from now on. No major white cast, smells good (like a sligh and faint powdery with real-vanilla), refreshes hair. I was doubtful of the volume claims but to my shock this actually works. I got a compliment on my hair for the first time in a while wearing this. I won't switch brands now."

Wake up to visibly smoother, plumper skin with this overnight oil that tackles wrinkles and redness while you sleep.

Shoppers Say: "I have been using this since December and it has helped my face so much. Dark spots, to fine lines. I know it is pricey, but there is absolutely NOTHING identical to it. My skin loves this oil."
