This duo brings thinning hair 'back to life' — save nearly 40% ahead of Prime Day

This early Prime Day deal will nourish and 'transform' tired tresses.

Shed happens. We typically lose about 50 to 100 strands of hair per day, according to the American Academy of Dermatology. That might not amount to much, considering that we have roughly 100,000 hairs on our heads that regrow regularly. But if you see your scalp starting to peek through, it might be time for an intervention. What if you could reduce the problem for less than $30?

Amazon's top-selling Bellisso Biotin Shampoo and Conditioner Set is a popular choice, and right now is a great time to try it out, since the duo is currently marked down to only $25.

After you get your hair looking it's best, be sure to check out our roundup of the best early Amazon Prime Day deals. Happy shopping!

With biotin, hydrolyzed keratin, spirulina extract and several other nutrient-rich botanicals, this shampoo and conditioner duo works to thicken thinning hair.

$25 at Amazon

Why is it a good deal? 💰

This popular set, beloved by 16,000+ five-star fans, is marked down to just $25 (from $40). That breaks down to $12.50 per bottle. Plus, the generous 16 fl. oz. size will last ages, and it's a fraction of the price of getting professional hair growth treatments. Snag this pair for $15 off before the price goes up again.

Why do I need this? 🤔

The formula — great for both men and women — is jam-packed with good-for-your-locks ingredients, like biotin, zinc, collagen, peptides and spirulina extract, all of which work together to help you achieve a fuller head of hair. DHT blockers could help prevent loss and thinning too. It's safe to use on colored hair. Got curls? Fine hair? Dry? Oily? No problem!

What reviewers say 💬

According to this duo's 16,000+ five-star fans, well, it just works — and it works so well that the words transformative and life-changing are used liberally when describing the results.

Pros 👍

"Hair that has life!" wrote one happy reviewer. "As a post-menopausal woman with thinning hair, this has brought mine back to life."

"From the very first time I used this, my hair was incredibly soft and shiny, and my roots weren't oily at the end of the day! I'm so amazed by this stuff," one shopper shared. "Three days into using this, a random stranger told me my hair was so beautiful and shiny. I was completely taken aback since my hair has been dyed and damaged for years."

One thrilled shopper called it their "holy grail" hair product, adding, "I have PCOS [polycystic ovary syndrome] and deal with mild hair loss and just overall dryness. This stuff is sooo good. I can’t believe how soft and healthy my hair is after one wash."

New mamas also swear by the stuff. One wrote: "I’m in the midst of some major postpartum hormonal hair loss, which resulted in [a] bald spot. I read reviews for this shampoo/conditioner and gave it a shot. So glad I did, as just two months later the bald spot had completely grown in! I’m ridiculously thankful for this shampoo and conditioner — just ordered another batch!"

Cons 👎

While the hair-nourishing results are impressive, some reviewers note a less-than-luxurious lather. And those with color-treated hair may want to alternate this duo with a color-saving shampoo to help preserve your shade.

According to one reviewer, "This shampoo smells great but doesn't lather up at all. Also, I could see some of the color in my hair going down the drain."

Other customers adore the product but would prefer a sturdier container: "The push pump from the shampoo container ... did not rise and once unscrewed it just fell apart," wrote one shopper. "I wanted to return the product but my wife wanted this product so much that she decided to use the shampoo the old-school way. The way it moisturizes our hair and leaves it with a highly scented aroma! We will continue to use both products from now on!"

Thinning hair? This duo may do the trick — over 16,000 Amazon shoppers have said it works for them.

"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!". "I wanted to return the product but my wife wanted this product so much that she decided to use the shampoo the old-school way (and I'm even using both shampoo and conditioner). The way it moisturizes our hair and leaves it with a highly scented aroma! We will continue to use both products from now on!
