Prime Day deals on expert-approved hair growth products
Botanic Hearth 100% Pure Rosemary Oil
Rosemary oil has gone viral on social media as a natural solution for hair loss — and according to board-certified dermatologist Dr. Michelle Henry, it actually works. “Rosemary oil is equivalent to 2.5% minoxidil, which is pretty impressive,” she told us.
To use rosemary oil, she suggested mixing it with a carrier oil (like grapeseed or coconut oil) and massaging it onto your scalp twice per day. Try it with this rosemary oil, which comes with a comb applicator for precise application.
Mielle Organics Rosemary Mint Scalp & Hair Strengthening Oil
This is one of Amazon's bestselling rosemary oils and a Black-owned brand that went viral years ago. If you are prone to hair loss and dryness, this product is a great problem-solver. Mielle's hair oil has amassed almost 100,000 ratings and receives praise for its soothing properties.
Mielle Organics Rosemary Mint Strengthening Shampoo
The brand also makes a popular shampoo that is marked down for Prime Day. It features rosemary oil and biotin, so the brand says that it can help soothe your scalp, increase circulation, nourish split ends and more.
"I love this shampoo, it makes my hair feel so good and I’ve definitely had way more fullness over time as I’ve used this, my baby hairs are even going insane!" one shopper wrote.
Pura D’Or Scalp Therapy Energizing Scalp Serum
Sometimes hair loss solutions come with unwanted side effects, but as one dermatologist told us, caffeine is a relatively well-tolerated ingredient and it may be helpful for certain kinds of hair loss. This serum is a popular option with more than 2,200 five-star ratings. Along with caffeine, the formula contains niacin, biotin, argan oil and antioxidants.
Rogaine 5% Minoxidil Foam
In all of our conversations with experts about hair growth solutions, minoxidil is the treatment that comes up most often. With consistent use, it has been proven to promote growth and is FDA approved.
And Rogaine's popular 5% minoxidil formula has been recommended to us time and time again by experts. “It’s a tried-and-true solution to help combat hair loss,” dermatologist Dr. Orit Markowitz previously told us. The foam works by penetrating your scalp and targeting hair follicles to reactivate the growth cycle, she explained.
Head & Shoulders Scalp X 2% Minoxidil
This treatment contains 2% minoxidil and, according to the brand, can provide noticeable results in just three to six months. Even better, it’s designed to absorb instantly into your scalp, so you’re not left with any greasy residue. You can grab it right now for its lowest price ever, according to price tracker CamelCamelCamel.
Pura D’Or Advanced Therapy Shampoo & Conditioner Set
Pura D’Or is known for its hair loss formulas and this shampoo and conditioner set is a popular pick. It contains a range of ingredients that are said to be beneficial for thinning hair, including rosemary oil and green tea. Don’t miss your chance to add it to your cart now.
"My hair was falling out by the handfuls," one shopper wrote. "After using this for a month, I noticed hair loss slowed considerably. 2 months later, I barely notice it. It really works!"
Nioxin System 3 Cleansing Shampoo
Another hair loss remedy can be found in this shampoo by Nioxin. For years, the brand has been a favorite among people with hair thinning issues for its focus on scalp health and thickening results.

Heeta Scalp Massager
One dermatologist previously told us that, in theory, scalp massagers like this one could increase hair growth. "Massaging the scalp can also increase blood flow, so again in theory, it delivers oxygen to the follicular bulb so that it stimulates growth,” she shared.
This massager has more than 114,000 five-star ratings and is also a favorite of writer Emma Stessman who says that she has used it to help her get a deeper clean on wash days for years.
OGX Thick & Full + Biotin & Collagen Volumizing Shampoo
Dermatologist Dr. Debra Jaliman previously recommended this shampoo for people with thinning hair, saying that it can help make your hair look thicker, thanks to the hydrolyzed wheat protein. Get it for just under $12 no.
Viviscal Hair Thickening Serum
Celebrity hairstylist Cheryl Bergamy previously recommended one of Viviscal's biotin-infused products — the Gorgeous Growth Densifying Elixir — but this one may also be suitable for thinning hair that needs extra volume.
Briogeo Destined For Density Caffeine + Biotin Peptide Density Shampoo
Caffeine can potentially help with hair loss and this product contains stimulating ingredients to boost microcirculation on the scalp. According to board-certified dermatologist Dr. Michele Green, “Caffeine is a stimulant that increases circulation, allowing beneficial nutrients and oxygen to be delivered to the hair follicles to keep them healthy."
divi Hair Scalp Serum for Women and Men
Fight frizz, nourish your scalp and promote hair growth with this scalp serum. The formula contains caffeine, peppermint oil and hyaluronic acid to support natural hair growth. Though the bottle is small, it comes with a powerful solution for thinning hair, including the power of tea tree oil.
Christophe Robin Cleansing Volumizing Paste Shampoo
Dermatologist and cosmetic expert Dr. Angela Lamb recommends this volumizing paste for those who need a fuller texture during temporary shedding. This product is meant to add more volume, especially if you’re going through postpartum hair loss. Plus, it’s color-safe and great if you have fine hair.
This product feels like a textured paste, lasts a long time and leaves your hair feeling extra clean.
