What could be better
•
A full system, not one product
Not available in physical stores
•
Opaque packaging
I personally like to see how much serum is left but, they make it easy by selling based on your plan commitment so 1 serum lasts 1 month.
My Verdict
MDhair is my top pick. With clinically proven ingredients that fixes your hair from the inside out, it is the best choice for hair regrowth, and the one I've seen work.
#2
Marine Collagen
The best of the supplements — feeds hair from within and finally combines a few things that work.
#2
What I Love
•
Feeds hair from within
Marine collagen plus biotin supports stronger, healthier growth from the inside.
What could be better
•
Doesn't block DHT, the hormone that causes hair loss
Great for hair health, but it won't stop the hormonal cause of thinning.
•
Not a full system
Still needs a topical to cover every angle.
My Verdict
Marine collagen + biotin supports hair from within. Most people do not have a biotin deficiency. It still lacks DHT support and is not a complete regrowth system.
#3
DHT Blocking Serum
Goes straight for the source — topical, targeted, one of the smarter picks.
#3
What I Love
•
Targets the source
Applied right where it matters to block DHT (a hormone that can cause hair loss) at the scalp.
What could be better
•
Still just one piece
Handles DHT, but not the nutritional or scalp-health side.
•
Only as good as the formula
Quality varies a lot between brands, so results aren't guaranteed.
My Verdict
A good DHT-blocking serum goes right for the source at the scalp — exactly where you want to hit hair loss. The catch: it's still only one part of the equation, and formulas vary wildly.
#4
Saw Palmetto Supplement
Now we're getting somewhere — a natural DHT blocker that goes after a real cause.
#4
What I Love
•
Blocks DHT naturally
Targets one of the main drivers of hair loss, no prescription needed.
What could be better
•
Only tackles one root cause for hair loss
DHT is a big piece, but not the whole picture of why hair thins.
•
Supplement-speed results
It's slow and won't get quick results alone.
My Verdict
Saw palmetto is a natural DHT blocker, but it is slower than medication and only addresses one aspect of hair regrowth.
#5
Rosemary Oil
The natural favorite everyone's trying right now — promising, but slow and hit-or-miss.
#5
What I Love
•
Cheap and easy to grab
A few dollars, no commitment — fine if you're genuinely low on a nutrient.
•
Smells lovely
Personally love the smell of rosemary!
What could be better
•
Slow and inconsistent
Results take months and vary wildly from person to person.
•
Not enough on its own
Can support a routine, but won't reverse real thinning by itself.
•
Messy & greasy to use
Rosemary oil needs to be diluted, usually with a carrier oil. That can mean oily roots, weighed-down hair, and an extra wash every time you use it.
My Verdict
Rosemary oil is a natural option, but that’s about it. Results are slow and inconsistent, and it’s not enough for real hair loss. It’s typically mixed with carrier oils, which can leave hair feeling greasy.
#6
Biotin
Everyone's first move, and honestly the least useful — it never reaches the root of the problem.
#6
What I Love
•
Easy and harmless
A few dollars, on every shelf, and safe to take.
What could be better
•
High-dose biotin supplements are sometimes blamed for breakouts
Biotin deficiency is actually uncommon, and evidence that supplementing biotin improves hair growth in people who aren’t deficient is limited.
•
Only helps if you're deficient
Unless you're genuinely low on biotin, it won't move the needle. Otherwise, it can cause breakouts.
My Verdict
Biotin's the default thing everyone reaches for, but it's rarely the fix. Unless you're actually deficient, it won't touch the real cause — DHT, hormones, stress.
#7
Nutrafol Hair Serum
Everyone's first move, and honestly the least useful — it never reaches the root of the problem.
#7
What I Love
•
Thoughtful, drug-free formula
Nutrafol takes scalp and follicle health seriously and uses a more sophisticated blend of botanical ingredients.
•
Established name in hair wellness
It’s one of the better-known brands in the category and has invested in clinical research around its products.
What could be better
•
One formula for very different problems
Hormonal hair loss, postpartum shedding, stress-related shedding and genetic thinning aren’t necessarily the same problem.
•
Daily application isn’t for everyone
Some users find scalp serums inconvenient or complain that they leave their roots looking greasy.
•
It’s expensive
You’re paying a premium for something that can still require months of consistent use before you know how much it’s helping.
My Verdict
Nutrafol feels more credible than most cosmetic hair serums, but it's greasy so people don't adhere to it. At this price, I’d rather invest in a regimen I realistically can afford to, and want to stick to.
#8
Minoxidil
Works for some, but the side effects are real — and the second you stop, it reverses.
#8
What I Love
•
FDA-approved and proven
The most-studied OTC option, and it works for some.
What could be better
•
Side effects are real
Scalp irritation and shedding are common, and it doesn't suit everyone.
•
You lose the results when you stop
Quit using it and the hair you grew back falls right back out.
My Verdict
Minoxidil is the proven OTC standby — FDA-approved and effective for plenty of people. But irritation and shedding are common, and it's a lifelong crutch. It does little to address the root cause.
My honest take
I'm not an influencer. I'm a hairdresser. I see what works and what doesn't, every single day. MDhair is the one I tell my clients about. The results are real and there's actual support behind it. Just take the quiz and what they build for you. And for a limited time, you can save up to 60% on your first order. No promo code needed.

Here’s what my clients have to say
Alisson - 3 months on the full kit
“The products are amazing!! After my baby girl my hair started shedding like crazy. I was really worried about my hair not growing back!! I did some research on different products. I decided to go with MDhair. Three months now. The shedding is gone. My baby hairs are starting to grow!!!”
Jenna - 5 months on the full kit
“I started using Mdhair in December of 2021, at first I was hesitant as I have never used a product like this. After almost 5 months I can definitely say looking at my before and afters and just the look of my hair there has been a big difference. My hair is stronger, thicker and darker!“

A game changer for me
My hair started to thin quite a bit and I tried so many things. This shampoo has been the only thing that made any difference. I get compliments all of the time. It actually filled in a little bald spot I had starting on the back of my head. Now I can put my hair into a pony tail again and not feel self conscious. Wonderful product and wonderful company.

MD hair has been a life saver
MD hair has been a life saver. I started using the shampoo, hair serum and vitamins last December. After 3 months, I have noticed a lot of hair growth. Prior to loosing clumps of hair, I was so used to having thick hair. I am thankful that MD hair helped restore hair growth. I do not notice a lot of hair fall as well. Thank you!

Baby hairs growing along my hairline… longer and stronger than ever
I've used MD Hair for four months and am pleased with my progress. Shedding has decreased, baby hairs are growing, and my hair is stronger. The team checks in regularly. I'm excited to see further improvements!

MdHair has been life changing!
MDhair has been life changing! I started about 4 months ago and have seen insane progress. The system is easy to use and there is plenty of product. I wash my hair every other day and have never run out of shampoo. The serum does not make your hair greasy. Vitamins are simple and the collagen tastes like nothing. It mixes into hot and cold liquids. Super happy with my results and the customer service!

New hair filling in sparse areas and getting thicker
Due to severe stress and thyroid issues I was experiencing a lot of hair loss and shedding. I have been using MD Hair since July and can see a big difference already. I have new hair filling in sparse areas and getting thicker. Which is a plus for me as I've always had thin hair.
