Today, molly tried out the Ultimate Repair Duo from Olaplex, consisting of number 0 and number 3. She mentioned that these two products are recommended to be used together, but she wanted to see if they would still deliver results when used individually. molly applied number 0 to the bottom half of her hair, making sure to saturate it well. She then followed up with number 3 on top. After letting the products sit for 10 minutes, she washed them out. molly didn't show the final result in the video, but based on her experience, it seems like the Ultimate Repair System by Olaplex is worth trying. She acknowledged that Olaplex products are designed to work as a system, but she wanted to test them separately to see if they lived up to the hype. This review provides valuable insight for those who may not be able to afford the entire product line.
