Raise your hand if you've lately been pulling more hair out of your brush or shower drain than usual. TBH, I've been shedding like crazy, which is admittedly not great since I can't really afford to lose body or volume, considering I'm already a member of the thin-hair club. In the past, I've had to clean up a few hairs off the bathroom floor, but between the pandemic and recently moving, my stress levels have officially peaked, and the amount of hair I'm finding around my apartment is ~a little~ concerning.

If this speaks to you, let me hit you with a fact before you have a meltdown (I wish someone had been there to hold my hand, lol!): Shedding is very common, with most women losing 100 to 150 hairs per day, scalp expert Kerry E. Yates, creator of Colour Collective previously told Shape. Everyone experiences some level of hair loss, thanks to genetics, illness, hormonal changes, stress, prescription meds, and dietary deficiencies. Even your hair styling habits can cause tress stress.

While there's a long list of likely causes, if you are experiencing extreme hair loss, it's a good idea to speak with your doctor or a trichologist, who specializes in hair and scalp health, to get to the root cause and to receive the right treatment recommendations. However, if you have normal shedding or if your hair is looking more blah than bombshell these days, shoppers have discovered HairGenics Pronexa Clinical Strength Hair Growth & Regrowth Therapy Hair Loss Shampoo (Buy It, $27, was $30,

The Pronexa formula is made with vitamins, biotin, and collagen peptides to strengthen your locks, produce keratin, minimize breakage, stimulate follicles, and promote growth. Plus, the shampoo is infused with ingredients like aloe vera and seaweed extract to help lock in moisture and further support hair growth. (Psst, check out the best products for thinning hair here.)

In particular, this shampoo contains one ingredient — saw palmetto — that could make all the difference for those suffering from hair loss. Saw palmetto is a botanical extract that has been shown to block the effect of dihydrotestosterone (DHT), the major androgen hormone involved in hair thinning, says Joshua Zeichner, M.D., director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. It's unknown as to why, but high levels of DHT, are associated with hair thinning in both women and in men, he adds.

Dr. Zeichner notes that although saw palmetto is a promising ingredient, you shouldn't expect to grow a full head of hair in the span of a few months, like some of the Pronexa before-and-after photos suggest. While various botanical ingredients have been shown to block DHT — and may be useful in hair thinning — Dr. Zeichner recommends also looking for a formula that promotes scalp health, so that the follicles can function optimally, and for one that helps thicken the individual hairs themselves. (

That being said, even if you're somewhat skeptical, HairGenics Pronexa Shampoo has nearly 2,000 glowing reviews from Amazon customers. They tout it for halting shedding, boosting the health of their tresses, and helping regrow hair in areas they had experienced thinning or even bald spots. One user, who put the shampoo to the test over a few months, said that it gave them more body and that their hairdresser has noticed new growth when they've gone to get a hair cut.

One reviewer wrote: "I waited to write this review until I used the product for 3+ months. I have tried at least 5 other hair loss shampoos and this one is my favorite. I definitely notice a lot less hair loss when I wash my hair with this shampoo. As a matter of fact, it's close to none. My hair feels healthy and full."

"With thinning hair due to hormones, I figured I'd give this shampoo a try. It really seems to work! I have new growth in areas where my hair was thinning and it seems to have made my hair stronger. I've purchased 3x so far," shared another.

"This has definitely slowed my hair loss," noted a customer. "I wanted to get a hair transplant this year and go to Turkey to do so. However, Covid stopped that plan. Until then, I started using this shampoo, and I have to say, it has slowed my hair loss almost to a halt. In fact, I see a bit more hair growth back, since I have been using this shampoo. I think I will continue using this even after the hair transplant I have eventually planned, keeping my new transplanted hair, and old hair as long as I possibly can. Fighting heredity! Love it!"

If your goal is healthier hair, you should definitely add this raved-about shampoo to your cart ASAP. But, you should know that the HairGenics Pronexa Clinical Strength Hair Growth & Regrowth Therapy Hair Loss Shampoo got so popular that it sold out on Amazon during Black Friday; luckily, the retailer re-stocked it just in time for Cyber Monday, and is offering 25 percent off the price. But, you'll want to act fast, as the deal ends at midnight tonight and it might sell out again. You can also scoop up the coordinating Hairgenics Pronexa Hair Loss Therapy Conditioner (Buy It, $27, was $30, on sale for Cyber Monday.
