This serum is impressive! After only a few weeks, my hair looks thicker especially on top. The serum is very lightweight and has a thin consistency that absorbs well. I like that my scalp feels hydrated but not greasy when I use it. It only takes 2-3 drops of serum per application so this bottle will last quite a while. I've been really happy with how healthy and full my hair looks now. This serum has been a great addition to my haircare routine!

This doctor for hair volition thickening scalp serum in 1.7 Oz is very useful for creating more volume in my hair. I appreciate that there was very little scent and it was easy to apply. Just the right amount with the dropper included this thickening scalp serum not only moisturized my scalp but made my hair feel Fuller and smoother. This is perfect for a once a week type treatment and the instructions are clear on applying it and leaving it on for a few minutes and then rinsing it out. I like this product as I feel like it works really well with my hair type. My thin hair just has a little more bounce to it now

I’ve used several Dr.FORHAIR products before and overall I tend to like what the brand does for hair and scalp care, so I had pretty good expectations.After using this serum consistently, I’d say it’s a solid product, but not one that completely stands out. It has a nice lightweight texture and it doesn’t leave my scalp greasy or heavy, which I like. It also feels soothing when applied and fits easily into a daily routine without any hassle. It dries fast so you can go on with styling.That said, the results have been fairly modest. My scalp feels a bit healthier and more balanced, and my hair looks slightly fuller, but nothing dramatic or noticeably transformative. It’s more of a slow and steady maintenance type of product rather than something that gives obvious visible changes in a short time.

I have an easily irritated and oily scalp. For the most part, I still have a lot of thick hair but it’s been thinning a bit near my temples from tying my hair so tight.I love most products from this brand so I was excited to try this. I like that the ingredients are minimal and skin safe. No silicones, which I need, so it won’t cause extra buildup on my scalp. The consistency is of a really thin serum. You can squeeze some on your fingers and apply where needed or drag the dropper slowly while squeezing lightly to apply.I’ve used it a few times now and it did not make my scalp itchy or oily. The first time I used it, I did feel a tingle from the menthol but it lasted a few seconds. It’s too soon to tell if it works so I will keep applying it daily. Since I’m only using it near my temples, this bottle should last me awhile. If you’re applying this all over with 1-2 dropper fulls as directed, you will go through this bottle quick.

I've tried many different hair growth items but this one is different. Looking at the ingredients and then the little pink encapsulated balls with the fluid shows that it's different. It has a very slight menthol scent that disappears a soon as it's applied. It doesn't leave my hair greasy or heavy. A little goes a long way. When applied it does have a very slight tingle. Obviously it takes weeks to see a difference but in optimistic.

I decided to give this a try since hair thinning runs in my family and I’m in my 30s so expecting it soon lol. And because I’ve had good luck with K-beauty skincare, so why not hair?It’s basically a rinse-out treatment that makes hair look and feel fuller. I’ve only been using it for about a week so this is mostly about first impressions and not prolonged results over time.The packaging is easy to use with a little dropper. I like that it comes in a small size bottle so you can get just a little to try before committing and spending a lot. The product itself is a creamy, opaque white consistency that’s thicker than a regular conditioner but not as heavy as some deep masks I’ve tried. It spreads nicely through damp hair without feeling greasy. The scent is light and fresh, kind of minty, not overpowering or artificially floral like something loaded with perfume. It rinses out cleanly too, no residue left behind.I use it after washing my hair (I just use head and shoulders, nothing fancy. Since I’m prone to dryness). I then apply this treatment from mid-lengths to ends, and work a bit into my scalp where I can. I leave it on for 3-5 minutes (the instructions suggest a couple minutes minimum) while I finish up in the shower, then rinse. It’s meant to be used a few times a week, not every single wash.I haven’t been using it very long but I already notice my hair being a little plumper and more voluminous right after rinsing, especially at the roots. My ponytail looks a bit thicker too. It’s not magic overnight growth, but it definitely creates a fuller appearance within the first couple of uses and builds from there.Haven’t noticed any downsides so far. No irritation or dryness.Overall, I’m happy with it and will keep repurchasing. I think the longer I use it, the more results I’ll see. And it’s already been working great so I’m sure the future will be even better.

I'm not sure if this is really expected to regrow hair, but it seems to market itself in that general direction. It does not. It does however, improve thickeness and shine in the hair you already have, which helps thinner areas along your hairline to look less thin. It smells very nice, and it applies very easily with a nice "its working" tingle to it, but aside from smoother, shinier hair around the application area, I've really not noticed any real difference in "growth". For being a leave in hair serum, however, it works pretty well. Overall, 4 out of 5 stars for slightly deceptive advertising.

I'm definitely on a hair growth journey and I've been trying different products to help me lose less hair and grow more hair faster. So far I'm really liking this serum because it's unscented, it can be applied either to a damp or dry scalp, and as long as I don't use too much of it in a concentrated area it doesn't make my hair feel sticky or greasy.I haven't experienced any skin irritation since I've been using this and while I can't say that I've noticed a lot of new hair growth I feel like I'm not shrdding quite as much, either. I've tried quite a few other products from Dr. Forhair and I've genuinely liked almost all of them so I felt pretty confident in trying this that I would end up liking it as well.I'm definitely looking forward to seeing how my hair looks a month or two from now after I've used this even longer but so far I'm satisfied with the the user experience as well as the results that I've seen in a short amount of time.

Excelente 10/10

This product definitely works!!! Buying my second bottle!! Consistently is key!!!

Mi sincera opinión usándolo es , sii funciona aunque arde un poco al principio como sensación de mentol , aún así lo usé y definitivamente disminuyó demasiado mi caída del cabello y ya tengo cabellos bebé 😭🩷 yo lo combine con minoxidil algunas veces y se los recomiendo bastante , este serum y el de KABA son mis favoritos , ahora compraré un bote nuevo 🥺

I decided to try this because I’ve had great experiences with other Dr. FORHAIR products, and so far I’m really liking it. The formula is lightweight, absorbs quickly, and doesn’t leave my hair greasy or weighed down, which is a huge plus for a scalp treatment.The dropper makes it easy to apply directly to my part and scalp, and the scent is very mild and fresh without being overpowering. After using it consistently, I’ve noticed my roots looking a bit fuller and my hair feeling healthier overall.I also appreciate that the ingredient list includes things like biotin, peptides, and vitamins that actually support scalp and hair health. It’s definitely more of a gradual, supportive product than an overnight miracle, but I think it’s a solid addition to a hair care routine.The bottle is small for the price, but a little goes a long way, and I think you get more than your money's worth with this brand.

I already use one of Dr.FORHAIR’s shampoos and noticed a difference with that alone, so I jumped at the chance to try this serum too. So far, I’ve been really impressed. It doesn’t weigh my hair down or leave it feeling greasy at all. My hair actually feels soft and smooth after using it, which I wasn’t expecting from a scalp serum. I’ve also started noticing less hair in the drain after washing, which has been a huge plus for me. Overall, this has fit really well into my haircare routine and I’ll definitely keep using it.

I love Dr. FORHAIR products and have not tried their Folligen line. My hair has been thinning and my part, widening due to menopause. I’m reviewing this product based on a first impression as it will take weeks for any visible sign of hair volume and fullness to be noticeable. First odd, this is just a little over 1 1/2 oz. Of product. At $30, it’s pricey. However, Dr. FORHAIR is a well-known and long trusted brand in Korea and has a strong following. So, I would expect this product to be worth the hype and price tag. The smell is somewhere between unscented and barely a trace of light fragrance. The texture of the serum is very lightweight. Using the dropper applicator, it is easy to target my middle part and I can see how the product will be used sparingly with the dropper dispenser. The results photos are impressive, but what I noticed is this is not a growth serum but rather it’s a hair plumper. The ad talks about “giving the appearance of” or “visibly more volume.” Though one claim is less hair breakage or hair loss. I suppose, if I am not breaking or losing the normal amount of hair, I am retaining more hair and that is a good thing, overall. The best part about this serum is the high quality list of ingredients. It packs a powerful cocktail of supplements for the scalp and hair that are all safe and proven ingredients that, in other hair products, would live up to their claims. I will use this serum daily and hope to report back some good results.

Generally speaking, I have a thick head of curly hair. However, like my mom, on one side of the front of my hairline is a quickly thinning patch. It has become so that I can't part my hair on the left anymore because it shows a balding area. This serum is from a line of products that specializes in hair thickening, so I am somewhat hopeful. It also speaks to specific use around the crown and hairline.I like that it does not have any scent, and have used it for a couple of days now after the shower in the problem region. Basically I massage it into the scalp, and then follow up with normal hair product. Unlike some plant oils, this does not leave your scalp extra greasy or wet looking, and a little will go a long way if you only use it for a few spots. I will report back if I see any significant change after repeated use!

There’s a very humbling moment in life where you’re minding your business, doing your hair like you always have… and then the lighting hits just right and suddenly your temples and crown are like, “hey girl, we’ve been thinning a little.”Yeah. That moment.After years of having thick, full hair without even trying, I realized I might actually need to participate in my hair routine now. So I started experimenting with scalp treatments, and this one from Dr.FORHAIR made its way into the rotation.First impression? Lightweight. Like, suspiciously lightweight. I was expecting something heavier or oily, but this absorbs fast and doesn’t leave my hair looking like I skipped wash day on purpose. Big win.The formula is doing the right kind of work behind the scenes. You’ve got biotin (the overachiever of hair ingredients), peptides helping support the look of stronger, fuller strands, and vitamin B12 backing it all up. It’s not some overnight miracle situation, but with consistent use, my hair does look a little more filled in around those problem areas. Not “brand new scalp who dis,” but definitely “okay, we’re making progress.”What I like most is that it feels realistic. It’s not promising fantasy-level regrowth in 3 days. It’s more like… giving your scalp the support it clearly should’ve been getting this whole time.I’ve also noticed my scalp just feels healthier overall—less dry, less “ignored,” if that makes sense. And since it’s not heavy or greasy, I can actually use it regularly without messing up my styling routine.If I had to nitpick, it’s one of those products where patience is required. If you’re expecting instant volume or dramatic change overnight, you’ll probably get impatient. But if you treat it like part of a routine instead of a magic fix, it earns its place.For around $34, it sits in that “mid-range but feels thoughtful” category. Not cheap, not outrageous, and it actually behaves like it respects your scalp.Final verdict: not a miracle worker, but a solid, consistent team player. And honestly, at this stage in life, I’ll take steady progress over empty promises any day.

I am a big fan of this brand as I have been buying the shampoo for my husband for about 6 months and I'm finally starting to notice new growth. I figured I would give the serum a try on my hair line which is beginning to thin with menopause. Following directions to shake bottle- I expel whatever is in dropper and pull up freshly mixed serum- apply three drops to my hairline and run into my scalp. It leaves a very pleasant tingle and leaves no greasy residue. I will update my stars if I notice no growth or phenomenal growth.
