Not only is this our favorite hair growth serum, A-list celebs like Nicole Kidman (an ambassador for Vegamour), Bella Hadid and Mandy Moore all sing Vegamour's praises. But what's really impressive is the before and after photos from actual users; the growth is incredible. In some cases, full bald spots are completely filled in. One user said: "It works! I’m constantly looking for products for my hair to grow. At age 60 this works for me!!! Thankful I found this product!! I have new hair growth around my hairline. My hair is growing and strong!!"

Viviscal, a brand synonymous with hair growth products, is slashing the price in half for its thickening shampoo (and conditioner) during Prime Day. Formulated with biotin and keratin, marine collagen and seaweed extract, the shampoo strengthens hair, reduces breakage, and promotes growth. If this shampoo doesn't fit the bill, check out our article on the best shampoos for thinning hair. 

Speaking of Vivscal supplements, the Men's Hair Growth Supplements are clinically proven to promote growth and prevent further thinning and shedding. And while $67 is a very pretty penny to pay, this is a 3 month supply, which is exactly the time it takes to see results with any hair loss product. The key is to stick with it, and you will have thicker, fuller hair by the time you take the last supplement.  

Sorry, ladies, this one is just for the guys. 

If you've done any research on the best products for hair growth, then you know Nutrafol is not only an industry-leading brand, it works really well. Nutrafol's Women Hair Growth Supplements anr recommended for women ages 18-44 and are clinically proven to promote visibly thicker and stronger hair. It's also dermatologist-recommended. Please note this is for a one-month supply - you'll want to stick with it for about three months. But while the price is hefty, the results are incredible, which you can see for yourself thanks to over 10,500 five-star reviews and many with before and after photos. 

Sorry guys, this one is only for the ladies. 

The Mielle Organics Rosemary Mint Scalp Hair Strengthening Oil might just be (in my humble opinion) the best oil on the market because it's fortified with hair growth powerhouse ingredients (30 essential oils!) and it doesn't cost an arm in a leg. It is by far my favorite, and I have tried my fair share of hair oils. Fun fact: Lab tests showed rosemary oil to be as effective as the FDA-approved hair growth treatment Minoxidil, but without all the side effects that come with medicated hair treatments. While we love this hair oil, if it's not the best fit for you, check out our top 8 picks for the best hair growth oils.

Comifer's cordless hair scalp massager with kneading has a whopping 84 massage nodes. By regularly massaging your scalp, you promote blood flow, circulation and better oxygen flow to the hair follicles, which promotes a healthy scalp and hair growth. The extra added bonus here is that you can use this massager all over your body to knead away stress, tension and minor aches and pains. 

PURA D'OR Professional Grade Biotin Anti-Hair Thinning Shampoo and Conditioner is clinically proven to be effective at promoting hair growth and preventing further shedding by blocking DHT production (a naturally occurring hormone that stifles hair growth). This product is so effective in clinical studies, the brand printed the studies directly on the labels!

If instant results is what you need, Nioxin Diamax Hair Thickening Treatment promotes instant hair fullness thanks to caffeine, Niacinamide and Panthenol. But please note, this is an instant fix, not a long-term solution to hair growth.
