The 30–90 day follicle rejuvenation cycle: real before-and-after images with consistent use of the MD HAIR™ system.
Before-and-after images shown with consistent use of the MD HAIR™ system. Individual results vary. Substantiation on file.
Step 2 of the MD HAIR™ system: condition weak, thinning hair where you see it. MD® Follicle Energizer is a drug-free, leave-in peptide serum with a precision brush applicator — designed by Dr. Susan Lin, M.D. for the hairline, crown, and part line where thinning shows first.
Biotinoyl Tripeptide-1 (Biotinyl-GHK) is studied at concentrations 10–30× lower than minoxidil requires and supports the look of hair-shaft diameter. It's blended with saw palmetto (a plant botanical studied for its interaction with DHT), horse chestnut seed extract, marine Ulva Lactuca botanicals, biotin, glutathione, and panthenol. Lightweight and non-greasy — it disappears into the scalp, not your hairstyle.
In a 17-week (119-day) self-evaluation study of the MD HAIR™ two-step system — Follicle Activator and Follicle Energizer used together — conducted by Spincontrol North America: 71% of the 24 subjects analyzed (32 enrolled) agreed their hair growth had improved, a statistically significant result, and 75% would recommend the product to a friend. The study was open and non-comparative, with no placebo group, and results are based on a self-evaluation questionnaire, not instrument measurement. Individual results vary.
Key Ingredients
Named, clinically-studied actives — not a generic conditioning blend. Rotate through each one.
A biotin-linked signalling peptide studied at concentrations 10–30× lower than minoxidil requires. It supports the look of hair-shaft diameter at the point where thinning shows first — the hairline, crown, and part line.
Benefit: Conditions weak, thinning hair so strands look thicker and denser.
A plant botanical studied for its interaction with DHT, the androgen most associated with pattern thinning. Included as the topical counterpart to the verbascoside used in MD Nutri Hair™.
Benefit: Drug-free botanical support applied directly where thinning is visible.
Horse chestnut seed extract is traditionally used to support microcirculation, paired here with marine Ulva Lactuca botanicals for a lightweight, non-greasy scalp feel.
Benefit: Keeps the serum invisible in styled hair — no residue, no grease.
Biotin supports keratin production, glutathione is the body's master antioxidant, and panthenol (vitamin B5) conditions the scalp and smooths the cuticle.
Benefit: Protects the follicle environment from the oxidative stress that accelerates thinning.
MD HAIR addresses the same biology the leading hair drugs are known for — the DHT pathway, follicle signaling, and the natural cycle — with plant-derived and peptide actives instead of drugs.
How to Use
Nightly on a clean, towel-dried or dry scalp. Draw the brush tip along thinning areas, massage in, leave on. No rinsing, no residue.

I got MD Follicle Energizer Natural Hair Growth Serum. The serum came in a tube that is very convenient to use, you just press at the bottom and get the right amount of serum on the brush on top. The serum is transparent and has a slightly perceptible pleasant smell. There is a slight cool sensation when applied to the head. This naturally liquid evaporates and this feeling is created. After that, I didn't feel anything. I used it as indicated in the instructions for about a month until it ended. Much to my chagrin, it doesn't work for me. I saw absolutely no difference. After reading the reviews of other people, I came to the conclusion that 30 days is a short time to see the result, some write about visible results after 3 months. Well, it’s possible. But I definitely have no result after 30 days of use. I think 30 days should have given at least some result and hope. I don't want to risk wasting money.

The problem spot I’ve applied this to shows some sign of thickening follicles. The initial application didn’t work as the instructions claimed and I required a second button press before I began to feel something being applied to my scalp by the bottle brush. First usage was a little awkward but subsequent use became easier and now I prefer the brush method over twist nozzles because it’s not as messy. The suggested usage doesn’t mention it but the bottle moistens the brush better when upside-down. An interesting product but as the instructions declare it could require using many bottles to see significant results. The bottle I have expires about a year from its receipt.

The bottle is not full with product when it arrives. I took a picture of how much product you actually receive in the tube. It seems to be helping increase the amount of baby hairs on the corners of my hairline. However, it has not made much of a difference on other parts of my scalp.

I received an expired product. I used it anyway and have not really noticed a difference after a month. I do like the application process, it allows the product to go on the scalp and not all in your hair. Unfortunately it has not done anything, whether this is from being expired I dont know.

I have always been worried about the scarcity/thinning of my hair near the forehead. So it was great to see that MD has this hair care product. I’ve been using it for two weeks now, once before going to bed every night. It has a very convenient design and can apply directly to the scalp with the brush. design. After each use, I rinse the bristles with water and then wipe them dry with paper towels. But need to very gentle otherwise the bristles will fall off as shown in picture. After two weeks now use I’m sad to report nothing has changed yet, I will continue to use it, hoping for a miracle!

It is easy to use it because of the applicator. Only one click on the bottom will push a small dose of serum and you can apply it where is needed. I have been used it for more than two weeks, I can see my new hair. I want to mention that I don't feel any scent. I don't like that this is slightly sticky. I am continuing to use that serum for better results that it is needed more than two weeks for sure.

Pros: *I noticed the very next day my hair shed significantly less in the shower *Natural ingredients Cons: *Very little product for high cost *My scalp required way more then the recommended one pump (more like 4-5 pumps every night) *Requires long term use to see little hair growth results *If you’re sensitive to scents this may bother you a little. Immediately when I tried this it has a very distinctive odor which reminded me of another hair peptide serum currently in my cabinet. After researching and comparing the ingredients side by side this is similar to the ordinary’s hair peptide serum. The consistency of this is a thick gel compared to the ordinary which is a light and watery like. For the little amount in each bottle along with expensive cost I will stick with the other brand which you get a lot more product and saves me thirty-one dollars.

Due to constant stress I’ve been noting A lot of areas of hair thinning so I decided to give this a try. Although this is still early to notice any major changes given this is recommended for 30 days use before you see changes, and one of these tubes actually has enough application for 30 days. So I’ll report back and see! It is a little tricky to figure out because there isn’t a specific instruction except apply to the hair follicle areas, however on my first application I felt a little tingly in the areas Applied. The tube actually can be opened up so you can see the contents inside (see first picture). In order for you to actually apply the product for the brand new tube you do have to pump it, or click three times before the product actually is registered in the applicator tip area. You can see from the brush on the third picture that finally the product does make it into the brush. My only issue with this is that this is slightly sticky and does leave a slightly fishy scent on your scalp, so it may not be so pleasant to go out with this product applied on you.

I think the overall product is ok. It will take time to see the actual results. The container is a bit confusing to use because different sections comes apart when I’m trying to open it to use it correctly. Eventually I got it to work, but the mechanics of the tube could be much better than it is.

I have been using MD Factor Natural Hair for several weeks and I have noticed a big difference. My hair feels stronger from the root, with less fall when combing and more natural volume. The texture is light, leaves no greasy or heavy residues, which I love because I can apply it and continue with my routine without problem. I have also noticed small new hairs growing, which gives me a lot of hope. In addition, the product has a soft and pleasant aroma. Compared to other treatments I've tried, this one really delivers what it promises. Very satisfied with the purchase, I recommend it to those looking to strengthen their hair and stimulate growth naturally.

I got this for my husband who is suffering from hair loss at the crown of his head; the ingredients looked promising so we decided to give it a try. The brush tip application is good in theory, but he said that it was a little difficult to reach all areas of his scalp without also getting a bit of product on his hair. Formula is a bit greasy as well, so take this into consideration when deciding what time of day to apply. My husband wears hats everyday for work so that didn't much matter to him. The smell of this serum is definitely strange, not in the best way, but I never noticed it unless I went up to him to smell his head, lol. So, per the directions, he's been only using one pump per application, but he said it wasn't really enough to cover all the areas that needed to be covered 🤦♀️ so he should have been using more. The amount in the tube has also lasted him a little over a month, so I'm also wondering if one click isn't dispensing the correct amount. However, after over a month's use, he hasn't noticed a visible difference and I don't see a difference unfortunately either. I wouldn't count this completely out, because like many products it may take months before seeing results. At this time I just can't justify buying another tube at $50 to test out that theory.

After a month of consistent daily use, absolutely no difference was seen. The product itself was okay, with no noticeable color or smell. It applied easily and the texture was light enough to not affect the hairstyle. Another issue with it was that the container was lightly unscrewed, so that when I clicked it to push the product into the applicator brush, it instead pored out into the area between the container holding the product, and the outer casing. I had to open it up and scrape the product out to use it. Maybe this needs more time to work, but a month is typically long enough with other hair growth products to see some sort of change, even if it's small. At this price, I can't afford another month or more to find out.
