Few things make your heart sink quite like the realization that your hair is thinning. Hair is a big part of your identity, and having to part with it can take a major toll on your self-esteem and emotional well-being.

It’s certainly not easy for the 50 million American men who shed their strands—some as early as their teens. But for the 30 million American women affected by hair loss, it hits a little differently. Simply put, women never expect to start balding—but by age 40, about 40 percent of women will be crushed to see their own hairlines receding or their scalps peeking through.

The vast majority of men lose their hair—mainly on top—to a genetic condition called androgenic alopecia, or male pattern hair loss, according to the American Hair Loss Association. But it turns out women also experience androgenic alopecia—and doctors have even coined the term ‘female pattern hair loss’ to describe the more diffuse, all-over thinning pattern it causes.

If you’re a woman, you can also lose your hair for reasons like stress, childbirth, and even hairstyles that pull too hard on the roots. It might cause you to scramble for a new hairstyle: one that hides all that thinning. But the right hair products can also make a serious difference.

Ultrax Labs Hair Surge shampoo uses an all-natural stimulant you’re very familiar with

Many products claim to make a difference, but we’ve gotten wind of a pretty potent shampoo that’s garnered praise from thousands of Amazon reviewers —and you’ll jump when you discover its key ingredient. Ultrax Labs Hair Surge shampoo uses caffeine to volumize thin hair, reduce breakage and promote a healthy, lush look overall. Customers claim they can even “feel the tingle...on my scalp” that lets them know it’s working.

Right now, Ultrax Labs Hair Surge shampoo is on sale for 20 percent off — and you can score an extra 10 percent off by using promo code 10HAIRSURGE at checkout.

Of course, Ultrax Labs Hair Surge isn’t a miracle—no hair product is—but there’s solid science behind the use of topical caffeine for hair loss. A study published by the National Library of Medicine compared the effects of small doses of caffeine to the effects of topical testosterone—which produces DHT, the primary culprit in androgenic alopecia. Predictably, the testosterone inhibited hair growth. But surprisingly, “caffeine alone led to a significant stimulation.”

Caffeine is acknowledged by doctors as an effective hair-thinning treatment—some have seen the results for themselves

“Caffeinated shampoos are invaluable when your hair starts to thin,” Sarah Brewer, a U.K.-based doctor and nutritionist, tells Yahoo Life. “Caffeine, applied directly to the scalp, will penetrate directly into your hair follicles."

Dr. Brewer confirms that even at low concentrations, topical caffeine inhibits the effects of DHT to stimulate follicles and promote more luxurious hair. She notes that caffeinated hair products also help relax smooth muscle fibers surrounding the hair follicles. “This reduces scalp tension,” Dr. Brewer says, “and allows small blood vessels to dilate and deliver more oxygen, vitamins, minerals and protein.”

“I use a caffeinated shampoo myself, [and it has] greatly improved the thickness and texture of my hair,” Dr. Brewer adds.

Ultrax Labs Hair Surge shampoo has a few other tricks up its sleeve to help make your hair healthier, too

But Ultrax Labs Hair Surge shampoo doesn’t only use caffeine to thicken the look of your locks. This potion relies on a trifecta of powerful ingredients that also includes saw palmetto—known to help naturally block the hair-inhibiting chemical DHT that’s produced by testosterone—and ketoconazole, an anti-fungal and anti-inflammatory ingredient that helps prevents dandruff.

It’s a power concoction of all-natural ingredients that come together to help promote thickness and bounce in a mane that’s fallen flat from shedding. And don’t worry, Ultrax Labs Hair Surge shampoo only makes it feel like your hair drank a cup of coffee. Thanks to essential oils, it has a “heavenly” mix of “yummy” citrus scents.

Amazon customers are obsessed with Ultrax Labs Hair Surge shampoo—it’s even ‘skeptic-approved’

Ultrax Labs Hair Surge shampoo is making a believer out of people who had been losing faith in finding a thinning hair product that would actually make a difference.

"Put the skepticism aside on this one...it works!!!" wrote one believer. "I am in my early 40's and lost a significant amount of hair due to a potassium deficiency that went undiagnosed until my hair started breaking and falling out...I've tried a few different products to no avail and was skeptical that this would actually work, but it DOES!!!...I am no longer removing massive amounts of hair from the shower drain on a daily basis!"

“Every time I cleaned my hair, I used to lose a ton of hair,” wrote another reformed skeptic. “When I used this product, I did not lose even one hair!...I try to keep things as natural at home as possible. Every single ingredient that I saw was actually not a chemical!...I have been using this for over a month now and am completely sold on the benefits. My hair fall has reduced at least by 80%-90%.”

One five-star reviewer said the shampoo worked so well that their new, healthy growth was even mistaken for 'helper hair.' "I got [Ultrax] to help with my thinning hair. I got more hair growth where I needed it and as a bonus my hair also grew in length," they wrote. "My friends thought I got extensions because of how fast and how long it grew!!!

Ultrax Labs Hair Surge shampoo isn’t cheap, but customers confirm that you get what you pay for with a product so effective. “It's expensive but it lasts a long time,” wrote one five-star reviewer. “I use three pumps and am still on my first bottle. As far as I'm concerned, this stuff is a miracle.”

Another proclaimed, "Sure it's pricey, but sooooooo worth every penny." They wrote, “I have had thin, fine hair all my life. I've tried everything out there to boost my hair volume. Hair Surge is amazing! It is hands down the best product I have ever used for volume...Everyone at work is commenting how great my hair looks and asking if I've done something new to it. Hair Surge is the wonder product for me. Can't say enough good things about it."

One reviewer who went from "thyroid bald to blonde balayage highlights in 3 months with this product" said that Ultrax Labs Hair Surge shampoo is "the only product I have ever reviewed for Amazon," and wrote, "do not let the price deter you, its expensive because it works, and I bought a bottle in August and am still using it in January...same bottle....small amount...it does not lather...just at the scalp and don't run it through your hair. I went from almost bald (thyroid) to soo much hair I just went to a blonde specialist and got highlights for the first time in my life...ladies...this works!!!"

Get your hands on a bottle of Ultrax Labs Hair Surge shampoo and see the results for yourself. You can even combine it with growth supplements and other hair loss treatments — Ultrax recommends this, in fact — to take back your self-confidence in 2021.
