We typically lose about 50 to 100 hairs per day, according to the American Academy of Dermatology. That might not amount to much, considering we have roughly 100,000 hairs on our head that regrow regularly. But if you’re noticing that your scalp is starting to peek through, it might be time for an intervention. While there’s certainly no shortage of in-office procedures that cost enough to make you consider just shaving your head, there are plenty of affordable at-home solutions — and they’re way less intense. The Bellisso Biotin Shampoo and Conditioner Set is an Amazon shopper fave, and for good reason: According to 14,700+ five-star reviewers, it just works. And right now is a great time to try it out — the duo is marked down to just $27 — a double discount! That’s just $13.50 per bottle.

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 give you a fuller head of hair. DHT blockers help prevent loss and thinning. It’s safe to use on colored hair. Got curls? Fine hair? Dry? Oily? No problem!

One shopper said it worked so well, she got major compliments.

“From the very first time I used this, my hair was incredibly soft, shiny and my roots weren’t oily at the end of the day!! I’m so amazed by this stuff,” she 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.”

It’s a miracle worker, according to another thrilled shopper. “I was about to get bald, but this product saved me! It’s like a miracle! I have been using it for a month. I can say for sure more hair came out and it really works!”

Even new mamas dealing with postpartum hair loss swear by the stuff.

Shares one: “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!”
