Over time, hair loss can become more and more common amongst both men and women. You might notice your hair seeming thinner than normal or coming out in bigger clumps in the shower. It's a process that can be confusing, frustrating and frightening.

When faced with thinning hair, Pura d'Or's Gold Label Shampoo and Conditioner set is what many Amazon customers reach for the most. Together, they are designed to combat scalp dryness and leave you with thicker, fuller hair — and the beauty duo has some rave reviews from verified buyers on Amazon as well as from Jennifer Birkhofer, vice president of commerce at NBC News.

Right now, you can get the shampoo at its lowest price ever for Black Friday. Plus, you can use code TODAY40 for 40% off site wide on Pura d'Or's website through Nov. 28.

Pura d'Or Gold Label Anti-Thinning Shampoo & Conditioner

"I heard about it [Pura d'Or's Original Anti-Thinning Biotin Shampoo] from one of my favorite hometown beauty bloggers. She talked about how much she loved the shampoo for thinning hair or hair regrowth," Birkhofer said.

"She shared a few progress photos specifically focusing on the regrowth of hair around her hairline, and they were really compelling. I had just had a baby and was nervous about all the hair I was losing, so I hopped on Amazon and bought it during a late-night nursing session," Birkhofer continued, adding she was especially swayed by the number of incredible before-and-after pictures from Amazon reviewers.

The anti-thinning shampoo is currently a No. 1 bestseller on Amazon for hair regrowth shampoos. It is made with a blend of natural ingredients like nettle extract, black cumin seed oil and pumpkin seed and, according to the brand, is "'manufactured in an environmentally responsible way."

"There are ingredients in the Pura d'Or shampoo, such as saw palmetto, pumpkin seed oil and rosemary, which have been shown to increase hair growth and hair counts in some small studies," Dr. Sejal Shah of SmarterSkin Dermatology previously told Shop TODAY.

The brand boasts that its formula helps to hydrate the scalp, which reduces dryness, brittle strands and improves hair manageability.

"I got the shampoo and conditioner bundle, and I actually love them both," Birkhofer said, noting her husband is a big fan as well. "My husband had bought it for himself. I have no idea how he found out about it, but it’s beyond hilarious that we bought the same hair-growth product off Amazon [without knowing]."

The more than 1,200 verified five-star reviews (and nearly 11,000 global five-star ratings) on Amazon agree with Birkhofer's feelings about the set. Many reviewers also noted that they noticed way less hair fallout after using the shampoo.

"It is incredible just how good this shampoo is," one reviewer wrote. "I had used it after an unfortunate incident with hair coloring that damaged and altered my hair, leading to a significant hair loss. It worked wonders."

"After a few weeks of use, my hair was stronger, shinier and I saw less hair in my bathtub and on my shoulders," another reviewer raved.

Other shoppers raved that their hair felt thicker and looked more voluminous.

"This shampoo is PERFECT for fine thin hair! said a five-star reviewer. "Now my hair has body and no more frizz! Amazing!"

Birkhofer noted that sometimes the shampoo can be a bit drying to her ends. So, she concentrates the product on her roots and follows up with a weekly deep conditioner or hair mask, like this beloved Wonder Water from L'Oréal.
