It's day two of Amazon Prime Day and the deals aren't slowing down anytime soon. And if you're hoping to have healthier-looking hair heading into spooky season and beyond, then there may be a shampoo to help support your hair goals.

That's one reason why Amazon shoppers can't get enough of this anti-hair thinning shampoo by Pura D'or. It's a hair wash specifically designed to help reduce hair thinning "by promoting hair strength and thickness" — and it's 23 percent off.

So, what makes this shampoo a best seller?

For one, it features a range of natural ingredients, including tea tree oil, aloe vera, argan oil and biotin. But most notably, the shampoo contains 17 DHT blockers. DHT is the main hormone believed to be associated with hair loss and shrinking hair follicles, according to Medical News Today.

Furthermore, its "clinically proven and tested" formula claims to help promote "hair strength and thickness," along with increased hair volume and less breakage.

And even if thinning hair isn't your top concern, the shampoo may help improve the overall quality of your mane thanks to mineral and vitamin-enhanced ingredients.

Although every shopper's experience varies, one reviewer raved about how they experience immediate results: "The results were instant. I comb my hair out in the shower and for the first time there was virtually no hair loss. Unlike similar products, this shampoo did not strip my hair of its natural oils."

Another reviewer also stated how it helped prevent further hair loss.

"Not only helped my hair [from] stop falling out but the conditioner made it soft and shiny."

They added: "I naturally have frizzy and dull hair so it really did wonders to my hair and saved me from going bald. I highly recommend this product. It is a bit pricey but your investment is worth it."

At the same time, the product isn't without its faults. One reviewer pointed out that although they saw improvements, you should not expect your hair to grow back.

"Your hair will never grow back with this shampoo, however, it will begin to regain some body, volume and that luster it once had. Not only that, but it halted the thinning process which I attribute a lot to harmful chemicals I was putting in my hair day in and day out."

So, whether you want to slow down thinning hair or help enhance your hair's quality, this might be the product to help you get to the next level on your hair journey.
