Ouai's Scalp Serum Surprised Shoppers Experiencing Postpartum Hair Loss

As a lifelong sufferer of scalp dryness and someone that’s been on a hair health journey for the past couple of years, I take scalp care very seriously. That’s why I was thrilled to find the Ouai Scalp Serum and delighted by all of the positive reviews from shoppers claiming that the product has made a dramatic difference in their hair health and growth — and right now, it’s up to 20 percent off at Sephora.

The serum is designed to help with hair thinning and scalp dryness. Reviewers say they’ve seen regrowth after hair loss thanks to its all-star formula packed with ingredients like hyaluronic acid, red clover flower extract, peptides, and glycerin, which work together to hydrate the scalp and boost hair density.

One reviewer noted that they were “shocked” to see their thinning hairline filling in with new baby hairs after online a couple of weeks of use. Another shopper wrote that their thinning hair had “more density and volume” after two months of using the Ouai Scalp Serum. One even said they can “definitely notice a difference in [their] bald spots” after using this serum. And one reviewer, who was dealing with postpartum hair loss, even said there’s “an extremely noticeable difference,” and that they were “shocked” by the way their hair “started to grow back from the normal hair loss related to my last pregnancy.” 

Personally, my favorite thing about this formula is that it can be used on both wet and dry hair. A lot of other scalp products and oils need to be washed out fairly quickly after application, but this one is designed to be used as a daily leave-in treatment. I like to use this on my scalp while letting the Ouai Detangling Leave-In Conditioner soak into my ends to keep my strands hydrated in between washes. The serum never makes my scalp or hair feel greasy, even when used on dry hair.
