Pantene Abundant and Strong Treatment Serum Review

My scalp used to be an overlooked area on wash days. But like many people, the rise of products dedicated to hair health changed things. Instead of focusing only on sudsing my curls clean, I started taking an interest in the skin that sits beneath them.

While I’ve dabbled in scalp-balancing serums before, I struggled to find a formula that delivered just as many benefits to my hair—and felt worth adding to an already lengthy wash routine. That’s what drew me to Pantene’s Abundant & Strong Treatment Serum ($20).

Designed for daily use and centered on reducing shedding and nourishing the scalp, it felt like a well-rounded approach to hair health—so I was eager to put it to the test. Ahead, here’s the science behind the serum, how to use it and my results after two weeks.

The Science Behind Pantene’s Abundant & Strong Treatment Serum

Scalp serums are a potent blend of ingredients designed to target areas of concern. Like facial formulas, they can help with dehydration and deliver the essential nourishment needed to keep the scalp healthy. Pantene’s Abundant & Strong Treatment Serum takes things a step further and is formulated to support hair density with regular use.

Its key function isn’t stimulating new growth, but supporting a healthier scalp environment that helps anchor hair follicles. The technical term for this concern is oxidative stress, which describes how free radicals negatively impact the scalp and the overall quality of hair fibers.

According to published research on the topic, oxidative stress is strongly associated with aging and is widely known for affecting the skin, scalp and hair. Pantene’s formula addresses this issue with a key antioxidant ingredient, piroctone olamine, which helps reduce the number of free radicals on the surface of the scalp. The formula also includes the brand’s Pro-vitamin complex (Pro-V), which provides nutrients to the scalp and nourishment to the strands.

How to Use Pantene’s Abundant & Strong Treatment Serum

This serum is made for daily use, which may be different from others you’ve tried. It can be used on wet or dry hair. To apply, part your hair into sections and dispense the desired amount directly onto the scalp. Massage it in, working the product into the scalp and roots. Once absorbed, you can style your hair as usual.

My Experience Testing Pantene’s Abundant & Strong Treatment Serum

While I frequently use scalp serums, I tend to reach for them only on wash days. As a straight natural, my curls recoil the minute they come into contact with water-based products, meaning treatments usually work best when my hair is freshly washed and not yet dry. Pantene’s Abundant & Strong Treatment Serum absorbs quickly when massaged into the scalp, which means I can use it daily (even after straightening my hair).

The dropper applicator features a tapered tip, allowing the product to be dispensed directly onto the scalp rather than the surrounding hair—another big bonus for my natural hair. While using the serum, I expected it would hydrate my scalp and decrease itchiness, but found that it did much more. After two weeks of consistent use, I noticed significantly less shedding when combing my hair in the morning. My scalp also felt noticeably hydrated throughout, and by the time my next wash day rolled around, there were fewer loose strands in the shower.

Needless to say, this drugstore serum has earned a permanent spot in my hair-care routine.
