Whether you're suffering from post-COVID hair loss (like Charmed star Alyssa Milano) or you've been dealing with thinning hair for years, shedding is an uphill — and often discouraging — battle. You're certainly not alone, though. Hair loss affects millions of men and women, but you don't need to spend a fortune on in-office treatments to put up a good fight. There are plenty of at-home regimens you can try first, and, according to Milano, one brand is so effective that you may never need professional help: The popular Nioxin anti-thinning hair system.

After publicly sharing her hair-loss story via video on Twitter, Milano found the help she needed within a few bottles. She praises Nioxin products (and Nutrafol supplements too!) for helping "tremendously" with hair loss. And she's not alone: These products have found fans in shoppers who say the treatments have helped curb their own hair loss and revitalized their manes.

Designed for a range of hair types, the Nioxin haircare system is designed to purify the scalp and promote thicker, fuller hair growth. Every System Kit contains a three-product base to help thicken hair: cleansing shampoo, which removes sebum and any environmental residue that may be clogging hair follicles; conditioner, which helps protect hair against breakage and control the balance of moisture in locks; and a leave-in treatment, formulated to leave hair thicker and appear fuller.

Each Nioxin System Kit is made with a specific hair type and concern in mind, and you'll get better results by choosing the one that suits your needs. Take this quiz from Nioxin, which divides their systems into three categories, to find your match.

Alyssa Milano isn't the only fan of Nioxin's Systems — over 18,000 reviewers on Amazon alone have given the various kits five-star ratings.

"Great for thinning hair," gushed a satisfied shopper. "I love this brand, and for thin hair, it's wonderful; smells amazing and helps [with] my hair growth and thickness. If you have never used Nioxin, you should!"

"Finally, a product that really works!" exclaimed another impressed user. "Just one use of this product made a big difference with my hair. I battle excessive dry hair and have tried so many products, including salon products, and never got the results I wanted or needed. This will be my forever hair-care product!"

"This product has been great," shared a final fan. "Less hair found in [my] brush. Seems to be working great with less hair loss."
