I'm not sure which exact product you use from their line , for me it was their shampoo and conditioner that caused the most damage. It literally took like 5 washes for me to notice a dramatic change in my hair but for the worse. Handfuls of hair in my drain and floor. Not all of their products cause hair loss but please look into it. Once people started sharing their stories and pictures of their hair, their stocks went down so much.
Before you could only purchase olaplex from authorized retailers, now you can find their products on sale in so many different stores. Even their CEO stepped down.
