Will it work on my hair type?
Yes. Straight, wavy, curly or coily, it makes no difference, because this goes onto your scalp rather than into your hair.
The texture is water-light, so it sinks in fast and leaves nothing behind. No grease, no residue, no flat roots. Wet hair or dry, morning or night. Ten seconds and you are out the door.
Key ingredients
Caffeine sits fourth on the ingredient list, ahead of most of the rest.
Niacinamide, panthenol and biotin round out the actives you already know by name.
Heartleaf (Houttuynia cordata) is the Korean botanical behind the (V)BioExo-Water named on the front of the carton.
Green tea, turmeric and licorice root make up the rest of the botanical side, alongside bisabolol and a trace of menthol for the cooling feel.
Fragrance-free. No minoxidil, no hormones.
How to use it
Three steps, about ten seconds.
Turn. Twist the comb head to unlock it.
Squeeze. Press it straight onto the scalp: hairline, part line, crown, temples.
Comb. Work it in with the built-in teeth. No rinsing.
Once a day, wet hair or dry, morning or night.

Ten seconds. Straight to the scalp.
The comb built into the cap parts the hair so the serum lands on the scalp, not on the lengths.
Thinning Hair Doesn't Have to Be Permanent
You are not alone. Thinning and shedding can start in your 20s, 30s, or 40s, after a baby, through menopause, from stress or hormones. And for most people, it begins far earlier than they expect.
Beyond the hair itself, thinning quietly chips away at your confidence. The photos you avoid, the part you keep covering, the mirror you stop looking in.
Our VAXA Korean scalp ampoule reaches the scalp, not the strand, with a silicone comb built into the cap so it lands exactly where you aim it.

What customers are saying about this product
“Honestly, I didn't have very high expectations... I've used quite a few products that claim to help with thinning hair or hair fall and honestly, most of them never made a noticeable difference. This one really surprised me. I've been using it consistently for about three weeks, applying it on both wet and dry hair. Personally, I prefer using it on damp hair because it feels easier to distribute evenly across my scalp. The formula is lightweight, absorbs quickly and doesn't leave my hair greasy or sticky... My only complaint is the size. The bottle is quite small, so I wish it contained a little more product, especially considering the price.”
“I honestly bought this product randomly and didn't expect much, but it ended up being one of my favorite hair care purchases. I've been using it consistently and I actually noticed some positive results, which was a nice surprise. The brush applicator makes it super easy to apply directly to the scalp, and it doesn't make my hair look greasy or oily afterward. That's a huge plus for me because I hate hair products that leave residue or weigh my hair down. It feels lightweight, absorbs quickly, and is very easy to include in my routine. My scalp feels refreshed after using it.”
“The packaging is very practical. it comes with a comb style applicator that helps distribute the product evenly on the scalp without making a mess, which I absolutely love. The serum itself is lightweight and doesn't weigh my hair down at all. It has no scent, doesn't leave any oily residue, and dries quickly... One of the main benefits I noticed is a reduction in hair fall, especially when washing and detangling my hair. I have very fine hair, and I feel like this product has really helped in that aspect.”
“it is really really good product that I will definitely buy again. this is very easy to use and my hair doesn't look greasy after this serum which is absolutely amazing because usually when I use something on my hair, it looks greasy so I'm really happy to use this ampoule. the only thing I don't like about this product that I need to wash the brush because after like we use it twice a day, I see that it gets dirty but after washing the brush, I use it as usual. I truly recommend.”
“I really like the comb-like applicator that spreads the product well through the hair in the desired areas! I had a thinning area near my temples, and now there's more hair there! We all know that hair regrowth products take time before you see real results, it's definitely a long-term process. That said, in just two weeks, less than a month, I already noticed small baby hairs starting to grow back, especially around my temples.”
“A nice leave-in treatment. I like that it is lightweight and non-greasy. I found the formula to be non-irritating. It properly absorbs and does not make the hair feel heavy or sticky. Love the brush applicator that makes the application easy and mess-free. It helped distribute the serum evenly. After continuous use, I experienced less hair shedding which was great. Also, the ingredients used help stimulate blood circulation.”
“The fact that this product was very viral influenced my purchase a bit. This doesn't change the fact, however, that I was still looking for a product that would help me with a slightly excessive hair loss and provide relief with eczema. I've tried it once so far and I'm quite happy because my hair has dried without being weighed down and because I felt a fresh sensation on the scalp.”
“The twist to turn it on and off avoids product leakage when stores. if you hold this against the scalp and move down your head while squeezing gently you will not end up with it all in your hair it will only be on the scalp. Has a really nice cooling effect on the scalp and feels very refreshing. Not sure about the long term just yet but its really nice”
“I have plenty of hair, but I've noticed that it has slowly started to thin, especially around the front of my head. Because of that, I started using this hair growth product. I've been using it for about two months, and I feel that the parted area of my hair looks slightly denser than before. It seems to be working for me, and I will purchase it again.”
“totally loved everything about this ampoule. It is soothing and has a soothing sensation on my scalp. Plus as someone doesn't like my scalp greasy, the products melts in perfectly after working it in. I feared that the brush won't go through my Afro hair too but the serum softens my hair while working it through and the brush works just fine”
“I started using this on my thinning areas near the temples. I apply it at night and massage it in gently. The texture is very light and doesn't make my hair greasy, which I love. After a couple of weeks, I've noticed less hair fall in the shower and my hair feels a bit stronger at the roots.”
“I have really liked this product so far. I feel like it hydrates and Suits my scalp and the applicator makes it really easy to apply it all over my head. I think I may be a little bit heavy-handed with it it's finishing quicker than I would have hoped. Would likely buy again when on sale.”
“The brush is very convenient for daily application of the product directly to the scalp as it helps spread the product and also massage at the same time. Also love the cooling effect it gives on the scalp. Is a great relaxing step for treating it as a routine.”
“The brush applicator makes it super easy to apply directly onto the scalp without making a mess, and it gives a refreshing, cooling feeling right away. My scalp feels healthier and less dry, and my hair looks softer and shinier after consistent use.”
