Hair growth is one of the buzziest beauty topics out there, and for good reason!
Whether you're experiencing thinning, shedding, or even patchiness, there are hair growth products (including serums, shampoos and conditioners) available that can help support your hair's health and regrowth, just in time for summer.
Even better? We spotted a few early Amazon Prime Day deals, so you don't have to wait until June 23 to start saving! But if the product you are eyeing isn't on sale yet... stay tuned because it may drop in price ahead of the major shopping event.
We've spoken with plenty of experts about buzzy ingredients like peptides (ICYMI, they're not just for your face) and minoxidil, and of course the latest product innovations, but scalp health also plays a big factor.
"When follicles are inflamed, clogged, or undernourished, hair can become weaker, shed more easily, or grow more slowly," board-certified trichologist Aga Tompkins previously shared with E!.
We found top-rated products that aim to build a healthy hair routine and lessen hair loss, backed by expert advice, shopper reviews and celeb recommendations. Read on for more hair growth advice straight from the experts, glowing shopper reviews, and to shop.

Paige DeSorbo swears that regularly combing her scalp with a lice pick has resulted in thicker, fuller hair. "I have been picking my scalp with a lice [comb] once a week for like six months and Iâm not kidding, I really think itâs helped my hair grow and be thicker," she told E!.

"Just like facial skin, the scalp should feel comfortable, hydrated, and resilient, not tight, itchy, overly oily, or flaky," board-certified trichologist Aga Tompkins shared. "When the scalp environment is healthy, hair is able to grow stronger, shinier, and more consistently."
Fast-absorbing and non-greasy, this serum reduces shedding thanks to a bio-tanical blend that keeps your scalp hydrated and roots boosted.
Shoppers Say: "If youâre thinking about getting this, get it. As someone with the long hair constantly have hair all over me this is significantly helped with shedding.

This affordable gem is loved by celebs including Kenya Moore, Madison LeCroy and Kandi Burruss. "All you have to do is, when you have shampoo in, just run this through your hair to remove product build-up and anything else. You've got to get one of these because, guess what, that's what's gonna make the hair grow," said LeCroy.
Aga Tompkins explained that "targeted scalp treatments" are a part of the puzzle for healthier hair. "Hair growth begins at the follicle, so scalp health directly impacts hair length, strength, and density."
This celeb-loved oil features a nutrient-rich blend of biotin, mint, and essential oils to support your scalp and strands from root to tip. The formula encourages natural thickness and infuses moisture into your scalp.

Peptides are all the rage right now, and they have taken over hair growth products! This leave-in formula from The Ordinary improves hair density by thickening individual hair strands.

This clinically proven Obagi scalp serum works to improve hair volume and decrease the amount of (dry and wet) shedding, while also addressing scalp dryness and damage. Key ingredients include biotin and amino acids to nourish and strengthen hair follicles. Apply it once daily and massage into damp or dry hair without rinsing.
Dr. Mamina Turegano, MD, FAAD, a triple board-certified dermatologist, internist, dermatopathologist, suggests a "scalp serum or treatment with clinically backed, growth-supporting ingredients like peptides, caffeine, biotin, panthenol, and arginine â similar to those in formulas like Obagiâs BioStim Scalp Serum. These help stimulate follicles, improve circulation, and create a healthier foundation for growth."
Made with caffeine, plant-based peptides, copper tri-peptide-1, and more powerhouse key ingredients, this lightweight serum refreshes the scalp while improving vitality, without weighing you down.
We may be focused on scalp care, but don't forget about the rest of your locks! This silky conditioner is ideal for fine hair, or anyone dealing with shedding.
Dr. Sheila Farhang, dermatologist, recommends looking for products with ingredients including:Â peptides, keratin, saw palmetto, rosemary oil, pumpkin seed oil, and FDA-approved minoxidil. And says that consistency and patience are key to results:Â "It takes time to see results. I would give any recommendations at least 6 months to start seeing a difference although some may see results sooner."
Minoxidil is the only FDA-approved ingredient for hair growth, and helps to maintain hair density, treat thinning hair and hereditary hair loss, and support fuller regrowth. This four-month, unscented foam supply has clinically proven results.
Shoppers Say: "It works! In November 2025 I was shredding hair daily by the handful. I started using this product nightly. I have very little hair shedding now (January 2026) and thicker healthier hair. It takes time and consistency to see real results. I suggest to perhaps try a single bottle first to check for allergies or other reactions before buying the double pack. If concerned about having to do this indefinitely, think of it like putting moisturizer on every night. It becomes a simple daily routine to keep a nice lock of hair on your head!"
Made with apple stem cells, aloe and sodium hyaluronate, this serum supports a healthy environment for hair follicle health and hydrates the scalp.
This serum is formulated with a blend of botanicals and studied ingredients to support healthier-looking hair from root to tip, improving the look of density without weighing hair down or leaving a greasy look/residue behind.
