The Nioxin Shampoo That Helped Alyssa Milano With Post-COVID Hair Loss Is 52% Off for Amazon Prime Day

Hair loss is a normal phenomenon, but it still can feel like a huge bummer to see your once thick and healthy mane begin to thin. For actress Alyssa Milano, falling strands were the result of another (unfortunately common) predicament: Catching COVID-19. While this potential post-COVID symptom has yet to be studied in depth, many COVID long haulers have reported noticeable hair loss after contracting the virus. Luckily, Milano found a regimen that "helped tremendously," which she shared with fans on Twitter earlier this year: Nutrafol supplements and Nioxin shampoo and conditioner.

One part of Milano's regrowth routine, the Nioxin System-1 Cleansing Shampoo, is normally quite a splurge, but right now it's on sale for a whopping 52 percent off at Amazon thanks to an Amazon Prime Day deal. Even at full price, shoppers highly recommend this hard-working shampoo to others with thinning hair. Made from a blend of refreshing peppermint, cleansing salicylic acid, and nourishing vitamin B peptides, this shampoo focuses on the scalp by removing dirt and build-up and strengthening hair at the root. What's more, the formula includes yeast ferments, which may improve scalp health, and in turn, potentially lead to regrowth.

For best results, the brand suggests using the Cleansing Shampoo everyday, taking care to massage into the hair and scalp for one minute before rinsing thoroughly. And while some hair growth products fall short of the amazing results they promise, Nioxin's regrowth shampoo is backed by five-star ratings from more than 6,000 users on Amazon alone.

"After one use, I had immediate results," commented one shopper, adding that "a little bit goes a long way, so it is cost efficient." Another reviewer, who tried a variety of hair loss products over the course of two years, was "happy" with the results they saw after using this Nioxin shampoo for a couple of months. "I feel like my hair is healthier, and the hair loss has slowed down," they added. (Looking to keep your hair strong and healthy? Check out these hair masks.)
