Does it really work for thinning hair?

Many customers report less shedding, new baby hairs and fuller-looking thinning areas with consistent use. Results vary, but this isn’t just another messy scalp serum, the built-in brush makes it easy to apply directly where thinning shows most.

When should I expect to notice changes?

Hair changes take consistency. Some customers notice less shedding first, while visible baby hairs or fuller-looking areas can take longer. The key is daily use and giving your scalp enough time before judging the result.

How long does one bottle last?

It depends on how much of your scalp you treat. Hairline-only use lasts longer than applying across multiple thinning areas or the full scalp. Use the selector above to get a more realistic estimate for your routine.

Will it make my hair greasy?

Most customers describe the serum as lightweight and easy to work into the scalp, especially when applied only where needed. If you’re prone to oily roots, start with a smaller amount and focus on the thinning areas instead of over-applying.

Is it suitable for sensitive scalps?

Many customers use it comfortably and like the cooling, refreshing scalp feel. That said, sensitive scalps can react differently to any topical product. Start with a small amount and stop use if you experience irritation.

My shedding finally slowed down

I was losing so much hair in the shower from post-menopause changes and had already tried Rogaine, but my scalp couldn’t handle the irritation. The biggest difference for me has been how little hair I’m seeing fall out now, plus visible progress around my hairline. I honestly didn’t expect to be this impressed.

Baby hairs after trying everything

I had already tried oils, pills, shampoos and gummies with basically zero results. Then I started noticing little baby hairs all over the areas where I apply this. It dries quickly, doesn’t leave my hair oily, and I’ve already ordered more.

I can see less scalp

My thinning had gotten bad enough that I could clearly see my scalp. I’m not claiming overnight growth, but after a few weeks my hair looked fuller and I was seeing noticeably less hair fall. That alone was enough for me to keep going.

Danielle S. | 46

I thought I got scammed

Halfway through the bottle I was skeptical and honestly felt like I got scammed. By the time I finished it, I started seeing significant baby hairs around my edges where I had been thinning. My only complaint is that it can run out pretty fast if you use it over your whole head.

Vanessa M. | 41

My hair looks fuller

At about three weeks I started seeing a difference, so I ordered another bottle. After a month my hair looked fuller and thicker enough that I ordered my third. I love the fresh feeling after applying it. I just wish each bottle lasted a little longer.

These short hairs are new

I wish I had taken a before photo because all these little short hairs around my hairline are new. I’ve tried so many products with zero positive results before this. It’s also surprisingly easy to apply and doesn’t leave my hair greasy.

Finally something I’ll keep using

I’ve dealt with thinning at my crown and an itchy scalp for years. Most products I tried were either greasy or smelled so strong I couldn’t stand them. This is quick to apply, my scalp feels much better, I’m shedding less in the shower and I’ve even started spotting tiny baby hairs near my hairline.

I wanted thickness, not length

I have very fine hair, so I’m not looking for longer hair, I just want to see less scalp. The crown of my head really does seem to be filling in more. It’s extremely easy to use, it isn’t greasy on me, and I already have another bottle waiting.

Less shedding when I brush

The first thing I loved was how refreshing it feels on my scalp. Then I started noticing less shedding when I brushed my hair and what look like little baby hairs around my hairline. The comb tip makes it really easy to get exactly where I want it without making a mess.

Marissa C. | 53

Easy even with long hair

I originally bought it for my daughter because her long hair was shedding, then started using it myself because I’m in my 50s and dealing with hair loss too. The comb makes application so easy, my hands stay clean, and my hair feels light and fresh instead of greasy.

Already on bottle two

I’m already using my second bottle. It doesn’t leave my hair feeling dirty or greasy, application is simple, and I really like the cooling sensation on my scalp. It’s become one of those products I actually look forward to using.

Nothing like a messy dropper

I expected another oily hair serum, but this feels completely different. The brush lets me cover the areas I want in one swipe without dripping serum everywhere. No sticky hands, no heavy roots, and it fits easily into my nightly routine.

My scalp feels refreshed

It absorbs cleanly and gives my scalp this cool, fresh feeling after I use it. With consistent use my scalp has felt healthier and my hair feels a little stronger at the roots. It’s simple enough that I actually keep up with it.

Camille T. | 45

Perfect for my hairline

The applicator is what sold me. I can part my hair and apply it directly to weaker areas and my hairline instead of coating all of my hair in serum. The cooling feeling after a shower is a nice bonus too.

Alyssa P. | 34

Good for my sensitive scalp

I’m careful with scalp products because mine can be sensitive, so I checked everything before trying this. I’ve found it fresh and comfortable to use, and the built-in brush makes applying and massaging it in much easier than the serums I’ve tried before.

Elise W. | 39

My thin areas look more filled in

I’ve tried other scalp serums before, but I keep reaching for this one because it’s refreshing and easy to massage in. After staying consistent, my scalp feels healthier and some of my thinner areas look a little more filled in. For me that makes it worth continuing.

Kristen L. | 46

Less hair in my brush

After several weeks my hair feels stronger and I’m seeing less hair come out when I brush it. The texture stays lightweight, and being able to apply it straight to my scalp makes it much easier to use every day without wasting product.

Meghan C. | 36

A really easy daily step

The brush is what makes this work so well for my routine. It spreads the serum directly across my scalp without making a mess, absorbs quickly and doesn’t weigh my hair down. I’ve also noticed less shedding and my hair feels stronger and healthier overall.

Adrienne K. | 41

Less shedding over time

What I noticed first was the clean, cooling feeling on my scalp. With continued use I started seeing less shedding and my roots felt stronger. I like that it gives me an immediate refreshed feeling while I stay consistent for the longer-term results.

Sabrina F. | 33

My roots look thicker

My hair is naturally very fine and has been damaged from heat and bleach. I started applying this after the shower on clean, damp hair, and my roots started looking and feeling noticeably thicker. I’m excited to see what consistency does over time.

Chelsea A. | 41

Actually feels good to use

I’m already into scalp care, so I’ve tried plenty of products that feel sticky or uncomfortable. This one feels fresh, the applicator gives a nice massage, and it’s so easy that adding it to my routine didn’t feel like extra work.

Nicole J. | 32

Not greasy at all for me

Greasy roots were one of my biggest concerns before trying another serum. I’ve used this on both wet and dry hair and it dries down without leaving that oily look. Once I brush through my hair, it actually feels soft and fuller.

Valerie M. | 52

Still giving it time

I don’t give five stars to products where the end result takes time, so four stars from me is pretty high. It’s easy to keep right at the scalp even with long hair, and I like using it. The bottle does feel a little small for the price, so now I’m waiting to see what consistent use does.

Your questions answered

Here you'll find the most important answers regarding usage, warranty, and results.

How do I use the serum?

Apply once daily directly to the areas you want to target, such as your hairline, part, temples or crown. Use the built-in brush to distribute the serum across the scalp, then gently massage it in and let it absorb. Consistency matters more than over-applying.

Can I use it on wet or dry hair?

Yes. It can fit into either a morning or evening routine. Apply it directly to the scalp rather than coating the lengths of your hair, and give it a moment to absorb before adding other products.

Can I use it with other hair products?

Yes. You can keep using your normal shampoo, conditioner and styling products. We recommend applying the serum directly to the scalp first and allowing it to absorb before layering heavier oils or styling products over the same area.

Is it suitable for color-treated or chemically treated hair?

The serum is designed for scalp application rather than the lengths of your hair, so it can fit into routines that include colored or treated hair. If your scalp is freshly treated, irritated or particularly sensitive, give it time to settle and patch-test before regular use.

Can I use it on my whole scalp?

Absolutely. You can use it only on targeted areas or across the full scalp depending on where you’re noticing thinning. Just keep in mind that full-scalp use will naturally go through a bottle faster than treating only your hairline, part or temples.

What happens if I stop using it?

Hair and scalp routines work best with consistency. If you stop using the serum, you simply stop the routine and the ongoing support it provides. We don’t position it as something you’re “locked into” forever. Use it for as long as it makes sense for your hair goals.
