Best Hair Regrowth Tonics of 2025

"I've been using Nutrafol Women's Hair Serum for 6 months now, and I couldn't be happier with the results. Recommended by my dermatologist for my hair loss, this serum has made a noticeable difference. I've seen new hair growth, and my hair feels thicker and stronger. It’s easy to apply and doesn't leave my hair greasy. I use it at night before bedtime. If you're struggling with hair thinning, this may be an option for you."

"I had a bald spot the size of a 50 cent coin when I started using this product. Now it's closer to a nickel and barely noticeable. I'm happy with the results and have already bought more. Thank you!"

"I'm not entirely convinced this serum justifies the price, but the capsules have definitely made a difference in helping my hair appear fuller again."

"I used the spray before, and when it ran out, I tried the drops. I feel more control over application, targeting exactly where I need it. After a few months with Keranique, I've seen new growth and my parts are no longer wide. I only use it once a day instead of the recommended twice, yet I'm still getting results. Everyone's experience may differ, though."

"After my hair thinned due to Covid, I was hesitant to try this product while still wearing a wig. However, about three months in, I noticed an increase in hair. The new growth is dark, contrasting with my grey, giving me a nice salt and pepper look. I do need to keep using it, as I shed again if I stop, which is why I rated it four stars instead of five. While I don't have full lush hair, it's a significant improvement, and I love not having to wear a wig anymore!"

"I've been using this for two months, and while I haven't seen much hair growth yet, I've noticed a significant reduction in hair loss. My hair feels soft and nice, not crunchy like some foams. I initially tried the spray pump but switched to the dropper, which I find gives me better scalp coverage. So far, it's a nice product, and I’m looking forward to seeing what results I get by May 2024."

“I've been using it for a month, but I haven't noticed any positive changes yet.”

“I purchased this for my husband, and it arrived lightning fast. So far, he really likes it since it doesn't irritate his scalp and doesn't have that medicinal smell.”

“It's kind of expensive, but the capsules work well. I'm aware it takes about six months to see results, though I noticed my hair thins out quickly once I stop taking it.”

"I absolutely love this product for my thin, fine hair. It really plumps it up and has a great fragrance without making my hair look oily! I spray it on my roots, dry my hair, and wow, fullness!"

"This thickening product has been a game-changer for my fine and thinning hair. It gives my hair a thicker and fuller appearance. My only downside is that the small bottle size means it runs out quickly, making it a bit expensive."

"After trying this product, my thinning hair looks and feels so much fuller. I've tested many others before, but this one is definitely the best! It doesn't leave my hair feeling sticky or heavy at all."

"After receiving a tip about hair tonics, I decided to give this one a shot. I've been using it for six months, and the results have been amazing. I've never experienced such great results from a hair product before. I’m constantly complimented on how thick and long my hair looks. I can’t believe it’s only $6! You should definitely try it!"

"I have very fine hair that tends to look frizzy and fluffy. I bought this tonic based on the positive reviews and my curiosity about copper peptides. After a month of use, my hair looks completely different. It’s thicker and shinier, and the texture is far more uniform. It doesn’t weigh my hair down, which I’ve never experienced with other products. I’m so excited that I just bought two more bottles!"

"At 75, I’ve noticed the common hair thinning that comes with age. While I can’t say it’s reversing genetic hair loss, this product does an excellent job of adding body to my hair and makes it appear thicker. I also use their Root Lifting Serum, which adds a bit of stiffness to my hair, and I’m pleased with the results!"

"I only started using this, so I'm unsure about the product's effectiveness. However, I absolutely love how fast and less messy the application is compared to other hair serums."

"I've been experiencing significant hair loss as I've aged. Since I began using this booster, my hair loss has drastically reduced. I haven't made any other lifestyle changes, so I can only attribute this huge improvement to this product!"

"I tried this for a couple of weeks but didn't notice much difference. I have frontal balding rather than overall thinning. The applicator was different from what I'm used to, and while it took some time to adjust, I actually liked it better. The serum was light and had minimal residue."

"After using this product daily post-shower, I've noticed an invigorating effect on my balding areas. The texture and feel of my hair have changed in just a few weeks. I'm committed to using it consistently and excited to see the results."

"This tonic from Deity America is my absolute favorite! It works wonders and I love the subtle aroma. It's not at all oily, making it a breeze to apply. I use it for both my scalp and hair, and it gives my hair a lovely soft texture. It pairs beautifully with other products from the line, and I can't recommend it enough!"

"Initially, I was skeptical about this product due to my past issues with dandruff and hair loss. However, after using it along with the shampoo and conditioner, I found that it eliminated my dandruff completely. My scalp feels relieved, and while I bought it for hair loss, it surprisingly tackled my dandruff problem too!"

"I've been using this product and love the lightweight texture that absorbs quickly, leaving no greasy residue. My skin feels softer and more hydrated, and my hair looks healthier and shinier."

"So far, I am thrilled with the exceptional quality of the LIV Authentic 100% Pure Honduran Batana Oil! It works wonders, making my hair and skin feel soft and moisturized. A little goes a long way, and I will definitely buy again!"

"I just received my order today, and so far, I'm pleased with the nice packaging and the light feel of the product. I'm hopeful it will help my hair grow!"

"I found this oil great as a pre-poo. No strong smell, which I appreciate!"

"Using this scalp serum as a pre-wash has been beneficial for me. My scalp feels less dry after applying it."

"I have dry hair and this Oil n Glow made it incredibly soft! I love how it tamed my flyaways, although I used a good amount for my thick hair."
